ABSTRACT
Background: -Frozen shoulder is an insidious condition that begins with pain and
gradual restriction of movement in the shoulder region. There are various methods of
treating frozen shoulder (both surgical and non-surgical).Among the non-surgical
methods there is no specific method accepted universally. Capsular stretching has been
used in the management of frozen shoulder but Muscle Energy Technique is a recent
technique and there are no studies done to study its effects on frozen shoulder. The main
objective of this study was to find out the effects of capsular stretching over Muscle
Energy Technique in the management of frozen shoulder.
Method: - This study includes 60 individuals with frozen shoulder who were randomly
divided into two groups and one group received Capsular stretching and the other group
received Muscle energy technique. The ROM and University of Pennsylvania Shoulder
Score (Ist subset) were considered for assessment and analysis.
Conclusion: - This study concluded that both Capsular stretching and Muscle energy
technique are effective in the management of frozen shoulder but Capsular stretching is
more effective in the management of frozen shoulder. Hence Capsular stretching can be
used as an effective method in the management of frozen shoulder.
Key words:-MET, Capsular stretching, Frozen shoulder.

INTRODUCTION
The expression “If you don’t use it you loose it” applies perfectly to diseases of
the shoulder because any voluntary or involuntary guarding of the shoulder may result in
loss of mobility.1The shoulder is the most movable but unstable joint in the body because
of the range of motion it allows. It is easily to subject to injury because the ball of the
upper arm is larger than the socket that holds it. To remain stable, its muscles, tendons
and ligaments must anchor the shoulder.1
Shoulder pain and stiffness are common presenting symptoms in patients who
seek evaluation from musculoskeletal physicians. A common quandary with this set of
complaints exists in determining the cause and effect cycle of the symptoms. It is often
difficult to establish which came first and whether pain results from stiffness or produces
it. To answer these important questions thorough understanding of the differential
diagnosis and pathophysiology of shoulder stiffness is necessary.2
Shoulder stiffness is a poorly understood disorder of the glenohumeral joint and
this poor understanding is partly due to the use of confusing terminology. Over the years,
the stiff shoulder was labeled initially periarthritis by Duplay in 1872,then frozen
shoulder by Codman in 1934 and later adhesive capsulitis by Neviaser in 1945.3Codman
described the disorder known as frozen shoulder as a “condition difficult to define,
difficult to treat and difficult to explain from the point of view of pathology. Neviaser
was the first to recognize “a chronic inflammatory process” that resulted in capsular
fibrosis, or thickening and contracture of the capsule.2
Page 14
2
Some of the more common terms that are synonyms for frozen shoulder are
adhesive capsulitis, periarthritis, stiff and painful shoulder, periarticular adhesions,
Duplay’s disease, scapulohumeral periarthritis, tendinitis of the short rotators, adherent
subacromial bursitis, painful stiff shoulder, bicipital tenosynovitis, subdeltoid bursitis,
humeroscapular fibrositis, shoulder portion of the shoulder of the shoulder hand
syndrome, bursitis calcarea, supraspinatus tendinitis, periarthrosis humeroscapularis,and
a host of foreign language terms.3
Peariarthritis covers a large group of disorders including tendonitis and tears of
the rotator cuff, calcifying tendinitis, bursitis.Therefore, this is not an acceptable term and
frozen shoulder and adhesive capsulitis are the preferred terms.4
The debate continues as to whether inflammation or fibrosis is the primary
pathologic process underlying frozen shoulder. It is generally well accepted that this
process whatever it is, is localized to the joint capsule to include synovial lining and
subsynovial tissue. Neviaser and Lundberg observed the role of inflammtion in the
development of frozen shoulder. The reason for this histologically observed
inflammatory reaction is unclear.3 It has been hypothesized that it could represent a
response to injury, an infectious agent, a chemical mediation.or an autoimmune reaction.
Cytokines seem to have a primary role in the inflammatory reaction and subsequent
capsular fibrosis. The role of cytokines in the initiation of inflammation is well known
and it has been shown that the sustained production of these substances can result in
fibrosis by stimulating fibroblasts. Radeo et al observed the role of specific cytokines
(platelet derived growth factor, transforming growth factor-β and hepatocye growth
factor in the inflammatory and fibrosing cascades specifically in frozen shoulder, in the
Page 15
3
primary and secondary forms. The initial trigger resulting in the proposed inflammatory
cascade and subsequent fibrosis is still unknown.2
Based on the etiology frozen shoulders can be classified as primary or secondary.
Primary frozen shoulder is an idiopathic condition, where the exact underlying cause is
not known.2 Frozen shoulder associated with a known underlying disorder is cosidered to
be secondary.5 Zuckerman and Cuomo have separated secondary frozen shoulder into
intrinsic, extrinsic and systemic categories.6 Intrinsic shoulder abnormalities include
rotator cuff tendinitis, rotator cuff tears, tendinitis of the long head of the biceps tendon,
calcific tendinitis and acromioclavicular joint arthritis. Extrinsic disorders which
represent pathologic conditions remote from the shoulder region, include ischemic heart
disease and myocardial infarction, pulmonary disorders including tuberculosis, chronic
bronchitis, emphysema, and tumor, cervical disc disease and radiculopathy, cerebral
vascular hemorrhage, previous coronary artery bypass graft surgery, previous breast
surgery, lesions of the middle humerus, and central nervous system disorders, such as
Parkinson’s disease.5 Extrinsic causes refer to the posttraumatic category, which can be
iatrogenic (post surgical) or may result from high-impact forces or low-level activity.2
Systemic disorders represent generalized medical conditions that are known to occur in
association with frozen shoulder which include diabetes mellitus, hypothyroidism,
hyperthyroidism, and hypoadrenalism.5
Frozen shoulder is a pathology of often unknown aetiology characterized by
painful and gradually progressive restriction of active and passive glenohumeral joint
motion (Baslund et al,1990;Pearsall and Speer,1998).Approximately 2-3% of adults aged
between 40 and 70 years develop frozen shoulder with a greater occurrence in women
Page 16
4
(Anton,1993;Connolly,1998;Stam,1994). Full or partial restoration of motion may occur
over months or years with or without medical intervention (Ogilvie-Harris et al, 1995).7
Codman stated that the patients with frozen shoulder have twelve features in
common. ‘The condition comes on slowly; pain is felt near the insertion of deltoid;
inability to sleep on the affected side; painful and incomplete elevation and external
rotation; restriction of both spasmodic and adherent type; atrophy of the spinatii; little
local tenderness; X-rays negative except for bony atrophy, the pain very tiring to every
one of them; but they were all able to continue their daily habits and routines.8
Condition comes on slowly 8Like frozen shoulder, there are many other
disorders of the shoulder such as impingement, which are far more common, and also
come on slowly. Codman had noticed that ‘they usually give a story of slight trauma or
overuse’. Surgery may be another initiating factor, for instance breast surgery and it had
been thought it was the immobilization, which led to the development of the frozen
shoulder. But, it is more likely the molecular response to the injury or surgery that is
responsible to the development of frozen shoulder.
Painful and incomplete external rotation 8Is the first distinguishing feature of
frozen shoulder. There are only four conditions that restrict external rotation. They are
arthritis, locked posterior dislocation, the late stage of a massive cuff tear and frozen
shoulder. All of these have specific radiographic changes. Arthritis shows diminution of
joint space, inferior osteophytes, sclerosis and occasional cysts; locked posterior
dislocation shows a ‘light bulb sign’ on the anteroposterior film and posterior dislocation
on the axillary view; massive cuff tear shows upward subluxation of the head with a
Page 17
5
break in Shenton’s line of the shoulder and irregularity of the greater tuberosity; while
frozen shoulder shows an entirely normal radiographic appearance of the shoulder.
Limitation of the spasmodic and mildly adherent type 8 In other words this is
better stated as ‘limitation of active and passive movement’. Limitation of passive
movement in the shoulder can only be caused by two things: firstly, irregularity of the
joint surface, as is found in arthritis and locked dislocation; and secondly contracture of
the ligaments that bind the humerus to the glenoid.
There are some rare muscular conditions such as deltoid contracture, which also
cause restricted passive movement, but in pragmatic terms, if the radiograph is normal
and the joint shows passive restriction, this can only be caused by contracture of the
ligaments of the shoulder capsule. The symptoms and signs of frozen shoulder suggest
that there is a contracture of the shoulder joint capsule.
Cyriax proposed that pathologies involving the glenohumeral joint capsule result
in a predictable pattern of joint restriction (capsular pattern) with lateral rotation most
restricted, abduction next most restricted, and medial rotation third most restricted.7
Stages of Frozen Shoulder9: -Neviaser and Neviaser described the arthroscopic
stages of frozen shoulder and stressed the importance of an individualized treatment plan
based on an understanding of the clinical stages of the disease. Frozen shoulder can be
broken down into four stages.
Stage 1: Here, the symptoms last for duration of 3 months and there will be pain
with active and passive range of motion. There will be limitation of forward flexion,
Page 18
6
abduction, internal rotation and external rotation. Examination with the patient under
anesthesia reveals normal or minimal loss of range of motion. Arthroscopy reveals
diffuse glenohumeral synovitis, which is often more, pronounced in the anterosuperior
capsule.
Stage 2: is also known as the freezing stage and it lasts for 3 to 9 months. The
pain will be of chronic nature with both active and passive movements. There will be
significant limitation of forward flexion, abduction, inernal rotation and external rotation.
The pain is very difficult for the patient to localize. The movement restriction may have
begun and the restriction is usually in both active and passive range of motion. The
patient often reports an impairment of a normal daily activity such as combing hair,
fastening a bra strap, putting on a coat, etc. The pain most often interrupts sleep and
sleeping on the affected side is impossible.
Stage 3: This stage is also known as the “frozen stage”. The symptoms last for
duration of 9-15 months. The pain will be minimal except at the end range of motion.
There will be significant limitation of range of motion with rigid “end feel”. In this stage
the primary restriction pattern is external rotation, abdction, followed by internal rotation.
Stage 4: This stage is known as “thawing phase” in which there will be minimal
pain and it lasts for duration of 15-24 months.
The total course of the disorder has been reported to self-resolve in 18 to 24
months.

The diagnosis of idiopathic frozen shoulder is made when other causes of pain
and motion loss are eliminated. Determining from the history which stage a patient is
vital to determine the appropriate treatment. Night pain and pain at rest are common in
the early presentation. Identifying associated factors in a patient’s medical history and
other medical conditions that may contribute to shoulder stiffness is important in
determining a diagnosis of idiopathic frozen shoulder.2
It is suggested that the diagnosis of frozen shoulder be one of exclusion (i.e, other
conditions should be ruled out before identifying the condition as frozen shoulder).
The conditions regarded as subgroups under the term periarthritis should be
eliminated before the term frozen shoulder is applied.4
Therefore, the term frozen shoulder should be reserved for limitation of specific
active and passive range of motion that is due to no known underlying disorder. If an
underlying disorder is found and frozen shoulder is present a qualification as secondary
frozen shoulder be given.4 The physical examination helps to identify secondary causes
of frozen shoulder and other diagnoses that may mimic symptoms suggesting frozen
shoulder and to document shoulder range of motion. Adequate documentation of the
range of motion is important in assessing the resolution or progression of shoulder
stiffness.2
The examination should not be limited to the symptomatic shoulder but should
include the opposite shoulder, cervical spine, and trunk. A thorough neurologic and
vascular examination of the upper extremities is imperative to evaluate for radiculopathy
or vascular causes of shoulder pain. The examination should include measurements of
Page 20
8
forward elevation, external rotation at the side, external an internal rotation in abduction
(preferably at 90° of abduction or maximal abduction if the patient cannot reach 900),
internal rotation up the back, and cross-body adduction. A limitation of external rotation
with the arm in abduction typically is associated with an anteroinferior capsular
restriction, whereas limited internal rotation and limited cross-body adduction are
associated with a posterior capsular restriction.2
Plain radiographs usually are normal in frozen shoulder, although they may show
osteopenia usually secondary to disuse and are helpful in identifying other causes of
shoulder stiffness and pain, such as osteoarthritis and tumor. More advanced imaging
techniques are not routinely necessary in the evaluation of the stiff shoulder but are
helpful in determining alternative treatment if the patient is not improving with the
typical rehabilitation program.2
The primary mode of treatment for frozen shoulder is prevention. Avoiding
prolonged immobilization of the shoulder after trauma or when shoulder pain develops is
key. Other than the importance of prevention, there is poor agreement on an optimal
treatment protocol. Because the pathophysiology of frozen shoulder is poorly understood,
many different forms of treatment are used empirically.
The overall goal of treatment is to relieve pain, restore motion, and to restore
function.2
Although frozen shoulder is generally considered to be a self-limiting condition
that can be treated with physical therapy, the best treatment has been the subject of
Page 21
9
extensive investigation. A variety of different treatments have been recommended, and
numerous studies have demonstrated successful results.
The types of treatment have included benign neglect, chiropractic manipulation,
oral corticosteroids, physical therapy exercises and modalities, brisement, manipulation
under anesthesia and arthroscopic and open releases of the contracture. Recent studies
have emphasized the surgical management of recalcitrant shoulder stiffness. Many of
these studies have been flawed because they have lacked objective and subjective
outcome criteria.10 Non-steroidal anti-inflammatory drugs, local anaesthetic and
corticosteroid injections into the glenohumeral joint, calcitonin and antidepressants,
distension arthrography, closed manipulation, physical therapy modalities and stretching
exercises can be listed among the most common non-surgical approaches to treatment in
frozen shoulder.11
Identifying the stage of frozen shoulder in which a patient is presenting is
important to determine the appropriate treatment regimen. Exercise is the key to any
treatment protocol for frozen shoulder.2 In this study the treatment for frozen shoulder
mainly consists of Capsular stretching and Muscle energy technique.
CAPSULAR STRETCHING The glenohumeral joint capsule has a significant
degree of inherent laxity with a surface area that is twice that of the humeral head. This
redundancy allows for a wide range of motion. This redundancy allows for a wide range
of motion. Medially, the capsule attaches both directly onto (anteroinferiorly) and
beyond the glenoid labrum and laterally it reaches to the anatomical neck of the humerus.
Page 22
10
Superiorly, it is attached at the base of the coracoid, enveloping the long head of the
biceps tendon and making it an intraarticular structure.12
The capsule also has a stabilizing role tightening with various arm positions. In
adduction, the capsule is taut superiorly and lax inferiorly; with abduction of the upper
extremity this relationship is reversed and inferior capsule tightens. As the arm is
externally rotated, the anterior capsule tightens while internal rotation induces tightening
posteriorly. The posterior capsule in particular has been shown to be crucial in
maintaining glenohumeral stability, acting as a secondary restraint to anterior dislocation
(particularly in positions of abduction) as well as acting as a primary posterior stabilizing
structure.12
On Pathologic examination of the shoulder joint capsule, in frozen shoulder the
joint tends to be contracted, thickened and closely adherent to the humeral head,
contributing to the limitation of movement.13In frozen shoulder, limitation of external
rotation with the arm in abduction typically is associated with an anteroinferior capsular
restriction, whereas limited internal rotation and cross-body adduction are associated with
a posterior capsular restriction.2The capsular pattern is designated by a hard end-feel and
limitation of all three passive movements in fixed proportions. Limitation of medial
rotation is slight; the patient cannot fully put her arm behind her back. The restriction of
glenohumeral abduction is more pronounced, but it is impairment of lateral rotation that
is most marked. In a case of medium severity, medial rotation would be limited by some
10-15 degrees, glenohumeral abduction by about 45 degrees and lateral rotation by 60-70
degrees. In a very mild attack, medial rotation is full but painful and the other limitations
amount to between 10 and 30 and some 45 degrees respectively.14
Page 23
11
The treatment of frozen shoulder should initially be conservative, with the
emphasis on passive stretching of the capsular structures.15Stretching for the anterior,
inferior and posterior shoulder should be performed by the patient as a part of the motion
programme.16Stretching a frozen shoulder can be painful but stretching slightly past the
point of pain is necessary to make forward progression in range of motion.2
Muscle energy technique17,18 is a direct hands-on therapy originally developed
by Dr.Fred Mitchell, Sr. Osteopathic physician, and continued by Dr.Fred Mitchell,Jr.
It utilizes the patient’s own gentle muscle contractions and body positioning to
normalize joint motion. It is a non-invasive technique that can be used to lengthen a
shortened contracted or spastic muscle; to strengthen a physiologically weakened muscle
or group of muscles; to reduce localized oedema to relieve passive congestion and to
mobilize an articulation with restricted mobility. Muscle energy technique targets the soft
tissues primarily, but it also makes a major contribution towards joint mobilization.
According to Bourdillon much of the joint restriction is a result of muscular tightness and
shortening. When damage to the soft or hard tissues of a joint is a factor, the periarticular
and osteophytic changes are the major limiting factor in joint restrictions. However, in
both situations muscle energy technique may be useful. In treating joint restriction with
muscle energy technique Sandra Yates in 1991 has suggested the following simple
criteria to be maintained:
1. The joint should be positioned at its physiological barrier-specific in three
planes.
Page 24
12
2. The patient should be asked to statically contract muscles towards their freedom
of motion away from the barrier of restriction as the operator resists totally any
movement of the part, the contraction held for 10 seconds.
3. The patient is asked to relax for 2 seconds or so between the contraction efforts,
at which time,
4. The operator re-engages the joint at its new motion barrier.
Muscle Energy Techniques are used to mobilize joint dysfunctions of both the
spine and peripheral joints. When a joint becomes “locked up” or moves out of neutral
position, this technique can work well to restore proper joint space.
NEED FOR THE STUDY
The treatment of patients with frozen shoulder remains controversial. Many
studies have been reported in the orthopaedic and rheumatology literature during the last
30 years. Treatment options documented in the literature include: benign neglect19,
supervised physical rehabilitation20,21, nonsteroidal antinflammatory medications, oral
corticosteroid, intraarticular injections, distension arthrography, closed manipulation22 ,
open surgical release, and more recently, arthroscopic capsular release.23 It is difficult to
compare the results reported in these studies because of the lack of documentation of the
stage of frozen shoulder being treated Shoulder pain and stiffness are common presenting
symptoms in patients with frozen shoulder. 2With its diverse origins pain about the
shoulder joint is most commonly related to the periarticular soft tissues. Keeping in view
the pattern of restriction is external rotation followed by abduction and internal rotation
Page 25
13
the treatment procedure should include methods to stretch the capsule so as to avoid the
frozen shoulder.10
Conventionally, treatment of frozen shoulder consists of heat therapy (superficial
and deep) along with joint mobilization.3As a new method of approach, the Muscle
Energy Technique targets mainly the relaxation of the soft-tissues. Studies have been
conducted to find the effects of capsular stretching and muscle energy technique but no
study has attempted to compare the effectiveness of these two techniques on frozen
shoulder. So this study attempts to compare the effectiveness of these two techniques on
frozen shoulder. In this study comparison of two treatment techniques i.e. muscle energy
technique and capsular stretching is done on 60 subjects with frozen shoulder.30 subjects
are treated with capsular stretching and the other 30 subjects are treated with muscle
energy technique

REVIEW OF LITERATURE
M.A.Harrast, Anita G.Rao (2004)2, have mentioned the use of a typical exercise
program of active and passive stretching with the goal of maintaining and regaining range
of motion in frozen shoulder. The basis of this program is four-quadrant stretching of
shoulder joint capsule which includes forward flexion, internal rotation, external rotation
and cross-body adduction. These exercises should be prescribed 4-5 times daily in the
supine position in order to stabilize the scapula and stretch the glenohumeral joint
capsule. Stretching slightly past the point of pain is necessary to make forward
progression in range of motion. At the initiation of the exercise, application of heat can
be helpful to reduce pain and facilitate stretching. After stretching, ice application can
help reduce inflammation and irritation.
Fusun Guler et al (2004)11 mentioned that nonsteroidal anti-inflammatory drugs,
local anaesthetic and corticosteroid injections into the glenohumeral joint,calcitonin and
antidepressants, distension arthrography,closed manipulation, physical therapy modalities
and stretching exercises are the most common non-surgical approaches to treatment in
frozen shoulder.
P.W.McClure et.al (2004)23 used the University of Pennsylvania Shoulder Scale,
which has subscales for pain, satisfaction, and functional activities. The combined total of
the the subscale scores may be used to determine a composite score based on 100 points,
with higher score being better. This scale has documented psychometric characteristics,
Page 29
17
including test-retest reliability (ICC=0.94), responsiveness (standardized response
mean=8.6, 90%confidence interval (CI), and a minimal detectable change score of
12.1(90%CI).
Captain Eric Wilson et al (2003)24 reported that MET combined with
supervised neuromuscular re-education and resistance exercises may be superior to
supervised neuromuscular re-education and resistance exercises alone for decreasing
disability and improving function in patients with low back pain.
Sarah Jackins (2000)16 has used capsular stretching in the non-operative
treatment of rotator cuff injuries, where she recommended her patients to perform the
capsular stretching of the shoulder 5 times a day. Each stretch is performed to the point
where the patient feels a pull against the shoulder tightness, but not to the point of pain.
Each stretch is performed for one minute and is found useful in improving the range of
motion.
Mantone et al (2000)16 have documented the importance of stretching exercises
for the anterior, posterior and inferior shoulder capsule as a part of the motion
programme to improve the joint range of motion in stiff shoulder.
Griggs et al (2000)10 reported that following a physical therapy programme
consisting of passive stretching exercises (forward elevation, external rotation, horizontal
adduction and internal rotation) at a mean follow-up of 22 months, patients demonstrated
a reduction in pain score from 1-57 to1-16 in a range from one to five points,
improvements in active range of motion, and 64 patients (90%) reported a ‘satisfactory
outcome.’
Page 30

Hannafin and Chiaia (2000)9 have mentioned that low load; prolonged stretch
produces plastic elongation of tissues as opposed to high tensile resistance seen in high
load, brief stretch. Heat may be used to promote muscle relaxation before stretching and
cryotherapy may be used to reduce discomfort after stretching.
BenzaminA.Goldberg et.al (1999)26 the majority of patients with frozen
shoulder can be successfully treated with a strictly home based physiotherapy program
consisting of 5 repetitions of each exercise 5 times every day with gentle stretching as
tolerated against directions of stiffness. For each exercise, gentle pressure as tolerated
against directions of stiffness. For each exercise, gentle pressure against the firm end
point of the range is maintained for a minimum count of ten.
Levit K (1999)25 states ‘The usual mobilization and manipulation techniques are
useless in dealing with the shoulder joint itself’. This highlights the critical importance of
soft tissue evaluation and treatment in shoulder joint in particular.
Frances Cuomo (1999)6 mentioned that nonoperative treatment is indicated for
those primary or secondary frozen shoulders with stiffness of less than 6 months and or
no previous treatment. Each patient should begin an active-assisted range of motion
exercise program complying with gentle, passive, stretching exercises. These exercises
should be performed four to five times daily, including forward elevation, internal and
external rotation, and cross body adduction. They can be performed standing or sitting,
but are most readily performed in the supine position. It is important to perform these
exercises gently, but it needs to be stressed that at each session the arm should be pushed
Page 31
19
slightly past the point of pain, otherwise no progress in the range of motion would be
expected.
BenzaminA.Goldberg et.al (1999)26 anterior capsule tightens during external
rotation and the posterior capsule tightens with internal rotation and cross body
adduction.
Harryman DT (1998)27 reported that in 226 frozen shoulders treated with
stretching exercises alone, Watson-Jones found that only 5% of patients did not regain
satisfactory motion with 6 months. However, Rizk et al (1998) noted that 60% of patients
treated with physical therapy achieved the ability to sleep pain free after 5 months
duration.
Helen Owens (1997)3 has mentioned the use of cryotherapy in frozen
shoulder.Cryotherapy, like heat application, produces increased circulation and
vasodilatation to the area. There is however, an initial vasoconstriction with cold
application. Ice can prove beneficial in reducing any post exercise soreness.
Mao et al (1997) 7reported statistically significant improvements in glenohumeral
active range of motion, and reappearance of the axillary recess (via arthrography) in
subjects managed with 12 to 18 sessions of physical therapy including moist heat,
ultrasound, passive joint mobilizations, and flexibility and strengthening exercises.
Craig Liebenson DC (1997)28 mentioned that in post-isometric relaxation or in
muscle energy technique for joint we first take up the slack and engage the barrier and
ask the patient to gently contract against your resistance away from the barrier. After a
Page 32
20
brief isometric effort, the patient is asked to relax and we wait for a release of the barrier,
when we feel it, we follow by taking up the slack to the new barrier.
Schenk et al (1997)25,29 performed a randomized controlled trial to determine the
effectiveness of MET for increasing lumbar extension in asymptomatic individuals with
each session lasting less than 5 minutes with each subject receiving 4 repetitions of the
MET maneuver two times a week for four weeks and reported a statistically significant
difference (p<0.5) in the increase of lumbar extension in the increase of lumbar extension
in the experimental group.
Melzer et al (1995) and Waldberg et al (1992)7 prospectively compared
outcomes of patients treated with a physical therapy regimen of moist heat, gentle
stretching, range of motion exercises, mobilisation, electro-analgesia (TENS) and
cryotherapy to outcomes of patients treated with either manipulation under anaesthesia
(Melzer et al, 1995) or subcutaneous calcitonin injections (Waldberg et al, 1992). Patients
treated with physical therapy in the Melzer et al (1995) investigation gained an average
active motion that exceeded that of the manipulation group, but the results were not
reported as statistically significant.
Pollock et al(1994)3, inspected 30 frozen shoulders arthroscopically and noted
subacromial bursal adhesions in al patients. He stated that a contracted glenohumeral
joint capsule is the primary structure responsible for frozen shoulder.
Petriquin 1992, Spencer 191625 mentioned that Spencer sequence offers precise
evaluation of even minor restriction in shoulder range and quality of motion, with the
added advantage of allowing treatment from the test position. Over the years the
Page 33
21
sequence of assessment has been modified to include treatment elements other than the
original mobilization intent which includes MET.
DiGiovanna 1991,Greenman 1989,Janda 1989,Lewit 1986,Liebenson
1989/1990,Mitchell 1967,Travell and Simons 199225 defined MET (Muscle energy
techniques )are sift tissue manipulative methods in which the patient on request, actively
uses her muscles from a controlled position, in a specific direction, with mild effort
against a precise counterforce. The counterforce can match the patient’s effort
(isometrically) or fail to match it (isotonically) or overcome it (isolytically), depending
upon the therapeutic effect required. Depending upon the relative acuteness of the
situation, the contraction will be commenced from or short of a previously ascertained
barrier of resistance. When MET is applied to joints, the acute model is always used i.e,
no stretching, simply movement to the new barrier and repetition of isometric contraction
of agonist or antagonist.
P.E.Greenman in 198917 told that MET can be used to lengthen a shortened,
contracted or spastic muscle; to strengthen a physiologically weakened muscle or group
of muscles; to reduce localized edema, to relieve congestion, and to mobilize an
articulation with restricted mobility.
Vladimir Janda (1988)16, acknowledges that it is not known whether dysfunction
of muscles causes joint dysfunction or vice versa, he points out to the undoubted fact that
they massively influence each other and that it is possible that a major element in the
benefits noted following joint manipulation derives from the effects such methods (high
velocity thrust, mobilization etc.)have on associated soft tissues. Normalization of the
Page 34
22
muscle tone by muscle energy technique provides an equally useful basis for joint
manipulation.
Robert J. Neviaser & Thomas J. Neviaser (1987)14 have mentioned the use of
gentle stretching exercise into elevation, external rotation and internal rotation under the
supervision of a physician and a knowledgeable therapist in the treatment of frozen
shoulder.
Lewit and Simons (1984) 30wrote that, “the use of post-isometric relaxation was
pioneered by Fred Mitchell Sr.and clearly described by F.L.Mitchell Jr.as a mobilization
technique that applies gentle force to improve ‘articulation’ and thereby restore
previously restricted movement”.
John Connolly et al (1972)31 have proved that self-induced passive stretching
exercise program was eventually successful in restoring satisfactory functional range of
shoulder motion in a large percentage (44%) of the hospitalized patients in their study.
McLaughlin (1961)31,32 has applied the analogy of the shrinkage which occurs in
immobilized uncured leather to the collagenous capsular shrinkage associated with the
“frozen shoulder”. In an attempt to combat this capsular shrinkage, the exercise program
should be designed to exert forces on the shoulder, stretching it beyond its limited range.
This can best be done by multiple, self-induced,repetitive passive stretching .

METHODOLOGY
Sample selection:
Sampling:-Simple random sampling.
Source of data: -. Patients with frozen shoulder were selected from the Out Patient
Department of Srinivas College of Physiotherapy and Rehabilitation Center, Government
District Wenlock Hospital and ESI Hospital. Prior permission was taken from the above-
mentioned hospitals to conduct the study and for ethical clearance.
Sampling Procedure: - A total number of 110 subjects were screened out of which 60
subjects were selected for the study. Each patient was screened initially by using a simple
selection proforma relevant to the inclusion and exclusion criteria. Those who fulfilled
this symptomatic criterion underwent a detailed physical examination of the shoulder for
baseline assessment (Refer Annexure 10.1).
Then the selected patients who were willing to participate were randomly divided
into two groups of 30 each in Group A and Group B. The details and the purpose of the
study were explained to all the patients and informed consent was obtained (Refer
Annexure 10.3) and demographic data (Refer Annexure 10.2) were collected from each
patient.
Group A subjects of frozen shoulder (18 females and 12 males) were treated with heat
therapy, capsular stretching and icing. Group B subjects with frozen shoulder (16 males
and 14 females) were treated with heat therapy, muscle energy technique and icing.

Procedure
The range of motion of the affected shoulders was assessed actively with a
universal double-armed transparent goniometer by placing the subjects in supine lying
position. The measurements were taken for shoulder flexion, extension, abduction,
internal rotation and external rotation.
Testing protocol for ROM2,33
Shoulder flexion
Subjects were positioned in supine with the knees flexed to flatten the lumbar
spine. The shoulder was positioned in 0 degree of abduction, adduction and rotation. The
forearm was positioned in 0 degree of supination and pronation so that the palm of the
hand faces the body. The scapula was stabilized to prevent elevation posterior tilting
(inferior angle presses against the rib cage) and upward rotation and thorax was stabilized
to prevent extension of the spine. Initially end feel was tested to measure flexion. The
fulcrum of the goniometer was flexed close to the acromial process. The midaxillary line
of the thorax and lateral epicondyle of the humerus were used as reference.
Shoulder extension
Subjects were positioned in prone with the head facing away from the shoulder
being tested and no pillow was used under the head. The shoulder was positioned in
slight flexion so that tension in the long head of biceps brachii muscle will not restrict the
motion. The forearm was positioned in 0 degrees of supination and pronation so that the
palm of the hand faces the body. Scapula was stabilized to prevent elevation and anterior
Page 39
27
tilting (inferior angle protrudes posteriorly) of the scapula and thorax was stabilized to
prevent forward flexion of the spine. Initially end feel was tested and to measure
extension, centre of the fulcrum of the goniometer was placed to the acromial process and
mid axillary line of the thorax and lateral epicondyle of humerus were used as reference
point.
Shoulder abduction
Subjects were positioned in supine and the shoulder was positioned in 0 degrees
of flexion and extension and available range of lateral rotation so that the palm of the
hand faces anteriorly. The elbow was extended so that tension in long head of triceps
would not restrict the motion. Scapula was stabilized to prevent upward rotation and
elevation and thorax was stabilized to prevent lateral flexion. Initially the end feel was
tested. To measure abduction, the fulcrum of the goniometer was placed close to the
anterior aspect of the acromial process and midline of the anterior aspect of the sternum
and medial midline of the humerus were taken as reference.
Internal rotation
Subjects were positioned in supine with arm being tested in available range of
shoulder abduction .The forearm in 0 degree of supination and pronation so that the hand
was facing the feet. The full length of the humerus was resting on the supporting surface.
The elbow was not supported and pad was placed under the humerus so that it was in
level with the acromial process. Initially the end feel was tested .To measure initial
rotation the goniometer was placed over the olecranon process and ulnar styloid was used
as reference.
Page 40
28
External rotation
The testing position is same as that for internal rotation of the shoulder. In the
beginning of the ROM, distal end of the humerus is stabilized to keep the shoulder in
available range of abduction. Initially the end feel is tested, to measure external rotation,
the goniometer is the same as for testing internal rotation of the shoulder.

Pain and function scores were taken using University of Pennsylvania Shoulder
score(1st sub set ) before the treatment ,after first week of treatment and after two weeks
of treatment.
Testing protocol for University of Pennsylvania shoulder score (I st Subset)5
The university of Pennsylvania shoulder score includes two 100 points scoring
systems. The self assessment 100-point scoring system is based on scoring of the
patient’s report of pain, satisfaction and function. The 100 point impairment score
consists of objective measures of ROM and strength. In this study the Ist subset of self
assessment is only taken to measure the patent’s report of pain, satisfaction and function.
It contains three pain items that address pain with the arm at rest by the side, pain with
normal activities, and pain with strenuous activities. All are based on a 10 point numeric
rating scale with end points of “no pain” and “worst possible pain”. Ten points can be
awarded for each item by subtracting the number circled from 10. Therefore, a patient
can be awarded 30 points for absence of pain.
The patient’s satisfaction with the function of the shoulder is also assessed with a
numeric rating scale. The end points chosen were “not satisfied” and “very satisfied”.
Scoring is based on the number circled by the patient. Therefore, the patient can achieve
10 points for this section.
Self assessment of function is based on a 20 item questionnaire with a 4 category
Likert scale for responses . Scoring for this section is calculated in the following ways; 3
points are awarded if the patient “can perform the activity without difficulty”, 2 points for
“some difficulty” 1 point for “much difficulty” and 0 for “cannot do at all” .Therefore,
Page 42
30
the patient can achieve 60 points if he or she can perform every item without difficulty.
Because some items may not be applicable to all patients, the response option “did not do
before injury “is included. When the patient chooses this response option or leaves an
item blank, an average of the items that were responded to is multiplied by 3 (maximum
score for each item), to yield the maximum possible score achievable by that patient. The
score for each relevant item is then added, and this total raw score is divided by the total
achievable maximum score for all relevant items, to yield a percentage of the points
assigned to this category. This percentage is multiplied by 60 points, to yield the final
functional score.
ROM and University of Pennsylvania shoulder score (1st sub set) was assessed for
both group A and group B subjects prior to the study, at the end of 1 week and at the end
of 2nd week i.e., on the day of completion of the study.
Group A: Subjects received treatment with moist pack for 10 minutes followed
by capsular stretching for the anterior, inferior and posterior capsules of the shoulder. To
stretch the anterior capsule the subject was positioned either in side lying with the
affected arm upwards or in high sitting and the shoulder and arms were brought
backwards into extension and this stretch was maintained for a minimum of 30 seconds
and maximum duration up to the point of pain experienced by the patient.15 Posterior
capsule stretching was performed with the subject in supine position and therapist
performing cross body adduction.15 Antero- inferior capsule was stretched with the
subject in supine position. To stretch the antero inferior capsule the affected arm is taken
towards the extreme of attainable elevation and counter pressure is maintained at the
patient’s sternum to prevent spinal extension. Each stress is gentle but firm and not
Page 43
31
released until pain rather than discomfort is experienced.13 Group A received capsular
stretching of 5 repetitions per set, 5 sets per session, 1 session per day and 5 days a week
for 2 weeks. Capsular stretching was followed by 10 minutes of icing to prevent post
exercise muscle soreness.

Group B: Subjects received treatment with moist pack for 10 minutes followed by MET
for abduction, flexion, extension, and rotation restriction which were again followed by
icing for 10 minutes. Subjects were positioned in the lateral recumbent position with the
involved upper extremity upper most.
MET for G.H.joint restricted flexion34: Therapist stands in front of the patient
and places one hand over the top of the patient’s shoulder at the superior part of the
scapula and cup the G.H. joint to palpate for motion .The other hand and forearm support
the patient’s flexed elbow and flex the humerus at the G.H . joint in the sagittal plane up
to the initial point of resistance. Direct the patient to extend the elbow against your equal
counterforce. Maintain the forces for 3-5 seconds, allow the patient to relax for 2
seconds, take up the slack and then repeat.
MET for G.H.joint restricted extension34: Therapist stands in front of the
patient and places one hand over the top of the patient’s shoulder at the superior part of
the scapula and cups the G.H. joint to palpate for motion. Uses the other hand to support
patient’s flexed elbow and direct the patient to push the elbow anteriorly.
MET for G.H.joint restricted abduction34: Therapist stands in front of the
patient, places her one hand over the top of patient’s shoulder, cups the G.H. joint to
palpate for motion. Direct the patient to press the elbow towards the body.
MET for G.H.joint restricted internal rotation34: Therapist stands facing the
patient. Carefully place the dorsum of the patient’s hand against the patients back.
Therapist places her hand over the top of shoulder and superior part of the scapula and
other palm protecting anterior side of the shoulder capsule. Places her other hand
Page 45
33
posterior to the patient’s flexed elbow. Direct the patient “Press your elbow against my
fingers”
MET for G.H.joint restricted external rotation34: Therapist stands behind the
patient. Places her hand superior to the patient’s GH joint. Places her forearm of the other
hand medial to the patient’s flexed forearm with her hand supporting the patient’s hand
and the wrist. Direct the patient to internally rotate the arm by pressing the hand.
Group B received muscle energy techniques for the shoulder joint of 5 repetitions
per set, 5 sets per session, 1 session per day, 5 days a week for 2 weeks with each
repetition maintained for duration of 7 – 10 seconds.

Table 5.5 shows the overall changes in range of motion of Group B following treatment
with Muscle energy technique in frozen shoulder between the weeks and within the
weeks of treatment. p=0.000 for extension and abduction, 0.001for external rotation,
0.024 and 0.012 for flexion and internal rotation which means that there is a significant
difference in ROM of all the ranges but extension and abduction showed more
improvement when compare to the other ranges.

DISCUSSION
Frozen Shoulder is characterized by painful stiffness of the shoulder that may
persist for several years. It is a common disorder, with an estimated annual incidence of
3% to 5% in the general population (Bridgman 1972, Pal et al 1986).Advocated
treatments include rest and analgesics, corticosteroid injections, acupuncture, physical
therapy, manipulation under anaesthesia, and arthroscopic or open surgery. There is no
general acceptance of one standard treatment (Green et al 2000).35
Frozen shoulder is a contracture of the capsule and depending on how severe the
contracture is (for it varies in intensity from patient to patient) the treatment is decided.8
The first objective in the treatment of patients with frozen shoulder syndrome is pain
relief. This is essential, for it permits patients to more readily participate in an exercise
program aimed at restoring motion and recovering function. 5The various physical
therapy approaches for treating patients with frozen shoulder include passive joint
mobilization, moist heat, electrotherapy, extensibility-enhancing exercises, strengthening
exercises and so on.7
The study was conducted on 60 patients with two groups of 30 each. Group A was
intervened with moist heat, Capsular stretching and icing whereas Group B was
intervened with moist heat, Muscle energy technique and icing. The output parameters
i.e,the range of motion(taken with 360 degrees universal goniometer)and pain and
function scores using University of Pennsylvania Shoulder Score(Ist Sub set) was
Page 62
50
measured prior to treatment (Pre-Rx), after 1 week of treatment and at the end of two
weeks of treatment.
1st objective of this study was to find the effectiveness of capsular stretching
(Group A) on frozen shoulder. In Group A subjects who received Capsular stretching its
overall effectiveness on range of motion was found using one way ANOVA which
showed p=0.000 which is very highly significant for all shoulder ranges between weeks
and within weeks of treatment. This means that capsular stretching is effective in
increasing overall shoulder range of motion. The week wise comparison of ranges of
motion obtained by Multiple Scheffe showed very highly significant ‘p’values for Group
A through out 2 weeks of treatment.
The 2nd objective of this study was to find the effectiveness of Muscle energy
technique (Group B) on frozen shoulder. In Group B subjects who received Muscle
energy technique its overall effectiveness on range of motion was found using one way
ANOVA which showed ‘p’ significant for all the ranges but highly significant for
extension and abduction. The week wise comparison of ranges of motion obtained by
Multiple Scheffe also showed highly significant ‘p’values for Group B through out 2
weeks of treatment.
The 3rd objective of the study was to compare the effectiveness of Capsular
stretching over Muscle energy technique in the management of frozen shoulder.
Comparison of range of motion of both Group A and Group B was done using
independent t-test which showed ‘p’ value significant for all the ranges and highly
significant for abduction, internal and external rotation during the last week of treatment
Page 63
51
which means that there is significant increase in these ranges of motion at the end of two
weeks of treatment and the positive mean difference proved that Group A is better than
Group B in improving the ROM.
The overall changes in pain, satisfaction and shoulder function of Group A and B
was obtained using Friedman test which showed p=0.000 for both groups which means
that there is significant overall reduction in pain and improvement in shoulder function in
both the Groups A and B.The week wise comparison of pain and current shoulder
function of Group A and B was done using Wilcoxson test which showed p=0.000 for
both Group A and B throughout the treatment but less significant for group B during the
first week of treatment. The intergroup comparison of pain and shoulder function was
done using Mann Whitney test which showed ‘p’significant after first week and highly
significant after two weeks of treatment. When we compare the mean ranks we can
conclude that Group A is better than Group B in improvement of shoulder function.
The results of this study supported the experimental hypothesis that both Capsular
stretching and Muscle energy technique are effective in improving the shoulder range of
motion in patients with frozen shoulder. On further analysis it also supported the
hypothesis that there is significant difference in effectiveness of both Capsular stretching
and Muscle energy technique. Our results support the study of Griggs et al (2000)35 who
reported that following a physical therapy programme consisting of passive stretching
exercises patients demonstrated a reduction in pain score from n1.57 to 1.16 in a range
from one to five points, improvements in active range of motion, and 64 patients reported
a satisfactory outcome. The mechanism by which Capsular stretching caused
improvement in shoulder range of motion and function could be elongation of tissues
Page 64
52
which could be the probable reason helping to improve range of motion and function
after Capsular stretching.7
The reason for MET being not so effective in improving shoulder ROM and
function in frozen shoulder could be attributed to the conclusion of the study conducted
by Johannes Buchmann et al. 200438 on upper cervical apophyseal joints with
mobilization and manipulation before, during and after endotracheal anaesthesia. They
concluded that post-isometric relaxation (MET) seems to reach mainly the muscular parts
of the treated motion segment and less to the other parts such as affiliated joint capsule,
ligaments and fascia.
From this study it can be said that Capsular stretching is better than Muscle
energy technique and can be used as method of choice for the treatment of patient with
frozen shoulder.
Limitations of the study
1. There was no control group due to ethical reasons.
2. Sample size was limited to 60.
3. There was no long-term follow-up of the patients after the study.
Recommendations for future study are
1. The same techniques applied for a longer duration say 4 weeks
2. On effectiveness of other exercise programmes.
3. The same study can be done with a longer follow-up.
Page 65
53
CONCLUSION
Both Capsular stretching and Muscle Energy Technique are effective treatment
techniques in the treatment of frozen shoulder. Further Capsular stretching is more
effective in increasing the range of motion and function in frozen shoulder.

SUMMARY
This study was conducted on 60 subjects at Srinivas College of Physiotherapy,
with an aim to find out the effectiveness of Capsular stretching over Muscle energy
technique on frozen shoulder. The subjects were divided into two groups of 30 each.
Group A received Capsular stretching with 5 sets per day, 5 repetitions per set and
5 days in a week each stretch held for a minimum duration of 30 seconds and maximum
duration up to the point of pain experienced by the patient with 10 minutes of moist pack
application prior to and 10 minutes of ice pack application after the stretching.
Group B received Muscle energy technique with 5 repetitions per set, 5 sets per
day and 5 days in a week with each contraction held for a period of 7-8 seconds followed
by a brief period of relaxation.
The shoulder range of motion (ROM) and University of Pennsylvania Shoulder
Score (part I) was considered as tool to measure the effectiveness of the interventions.
The range of motion and University of Pennsylvania Shoulder Score were taken prior to
treatment, at the end of 1 week of treatment and at the end of two weeks of treatment.The
analysis led to the finding that:
1. Both the groups showed improvement in shoulder range of motion and function
after 2 weeks of treatment.
Page 67
55
2. Group A of Capsular stretching showed better results when compared to Group B
of Muscle energy technique in the improvement of range of motion and function.
3. Capsular stretching showed a significant difference when compared to Muscle
energy technique in its effectiveness on frozen shoulder.
4. Both the groups showed improvement in shoulder range of motion and function
on frozen shoulder.
This proves that both can be preferred for treatment of frozen shoulder whereas
the first preference can be given to Capsular stretching as it is more effective in
improving shoulder range of motion and function in frozen shoulder.
