DPT 707 Musculoskeletal I Lumbar Spine Patient “Conversation” and Physical Examination Primer
I. Structures capable of producing symptoms
Lumbar spine symptoms can come from a variety of structures that are located both in the
anterior and dorsal compartments of the spine. Any structure that is innervated by the nervous
system has the capacity of being a potential source of symptoms. This can include but is not
limited to the zygapophyseal joints, the intervertebral discs, ligaments, muscles and fasciae of
the lumbar spine (Twomey and Taylor 2000). The innervation of these somatic structures is
based upon their orientation in the anterior or posterior column of the spine. Below is a list of
structures and their innervation sources based on innervation. This can serve as a good guide
for your hypothesis of “potential structures” that you would need to investigate.
Column Structure Innervation
Anterior Vertebral bodies Located deep into the cancellous bone and vertebral end plates: Anterior and Posterior Plexi *
Anterior Intervertebral discs Outer 1/3 of the annulus, proprioceptive role but can also be nociceptive: sinuvertebral nerve *
muscle tone, and bilateral glove sock distribution
5.) Physical Examination Considerations: a lower quarter neurological examination is required
for all patients in which you want to perform any neurodynamic testing of which includes
slump, straight leg raise, or if mobilization of the nervous system will be an eventual treatment
approach you may take .
Standard PNS or LMN screening should include:
1. Sensory testing
2. Deep tendon reflexes
3. Strength testing (myotomes)
Standard CNS or UMN screening should include:
1. Babinski sign testing
2. Clonus testing
3. DTR’s (hyper-reflexia)
4. Sensation testing for bilateral glove / stocking presentation
5. Assessment of muscle tone via passive movement of the extremities
Neurodynamic Assessment (will review in week 4):
1. Passive neck flexion in supine
2. Straight leg raise
3. Slump testing
Neurodynamic tests are movements which place or presume to place a load onto the nervous
system (Butler 2002). These are often tests used to determine where a peripheral nerve may
have static or dynamic issues either based on the nerve itself or the tissue container it is located
in (i.e. fascia, muscle etc). Because this can often be a mobility issue and not necessarily a
conduction issue there may or may not be true neurological changes.

Peripheral Neurogenic Pathology:
Peripheral nerve trunk: Pathology at the peripheral nerve trunk creates a pattern of altered
sensation corresponding with the cutaneous distribution of that peripheral nerve distal to the
site of the pathology.
Spinal nerve root: Pathology at the spinal nerve creates a pattern of altered sensation in a
dermatomal distribution.
Pathology affecting the peripheral nerve trunk (PNS
lesion) includes one or more of the following
neurological signs:
1. Altered sensation in a cutaneous field pattern distal
to the site of pathology
2. Absent / decreased strength in muscles supplied by
the peripheral nerve trunk distal to the site of the
lesion
3. May include absent or decreased DTR’s if the
peripheral nerve trunk innervates the muscle tested
by the DTR (e.g pathology affecting the femoral nerve
may cause absent/ decreased patellar DTR because
the femoral nerve innervates the quads).
Pathology affecting a spinal nerve root includes one
or more of the following neurological signs:
1. Altered sensation in a dermatomal pattern
2. Absent / decreased strength in a myotomal pattern
3. May include absent or decreased DTR’s
*may present as “Radicular Pain”

V. Beginning the Physical Examination
According to Cook (2012) there are 5 key criteria the therapist should have established prior to
initiating the objective examination. They are the following:
1. A list (or no findings) that represent potential red flags to items that require further
testing to “rule out” a condition.
2. Post subjective set of competing HYPOTHESES to allow the clinician to isolate certain
components of the physical examination for more specific findings.
3. The nature of the problem driven by the severity, irritability and stage of the condition.
4. The patient’s expectations and prediction of the outcome (through goals).
5. The concordant or asterisk sign and a hypothesis of what physical activities may be
associated with it. The concordant sign will drive the examination and subsequent
treatment.

VI. Lumbar Spine Physical Examination
A typical examination structure includes the following:
1. Observation (including posture and gait)
2. Structural differentiation tests
3. Active physiological movements
4. Passive physiological movements
5. Passive accessory movements
6. Special clinical tests
A pattern of patient positing during the examination tends to follow a STAND → SIT → SUPINE
→ PRONE. These positions may vary in order based on the patient’s tissue irritability, severity of
the condition as well as the need to provide highly sensitive tests first to rule out sinister
pathologies. A neurological examination may be needed based on the key criteria described
earlier in this chapter. The neurological examination may be integrated throughout the
examination or done as a separate entity when deemed appropriate.
Observation:
Posture
2 key points need to be understood about posture in general. 1.) The observation of posture
involves the careful identification of potential contributors to the patient’s impairments, and 2.)
the presence of a postural fault or body asymmetry does not dictate a pathology or
impairment. Keeping those points in mind postural dysfunction can be the cause of painful
conditions especially those which involve microtrauma to myofascial, periarticular, articular and
or neural tissues (overuse). The other factor is that postural dysfunction can be caused by
painful conditions in which the patient adopts postural positions that inhibit optimal conditions
for tissue healing (adaptive). When one assesses posture the following ideas and or thoughts
should be concerned as it applies towards your clinical reasoning process:
Muscle length impairments
Muscle strength and or endurance impairments
Relationship / interaction of muscle length / strength
Movement patterns / muscle firing sequences
Joint mobility impairments
Symptom avoidance posturing (could be an insight into a maladaptive issue)
Structural anatomic impairment
Development features (changes in posture throughout the lifespan)
Neurological examination: LMN / UMN and or
Neurodynamic testing as needed (can be
integrated in exam or added when appropriate)

Postural Grid
Good posture Part Postural Faults Muscle Impairments Intervention
Head is held erect in a position of good balance
Head
Arms hang relaxed at the sides with the palms of the hands facing toward the body. Elbows are slightly bent, so forearms hang slightly forward. Shoulders are level and neutral in the frontal plane. Scapulae lie flat against the rib cage ~ 4 inches apart
Arms & Shoulders
A good position of the chest is one in which it is slightly up and slightly forward (while the back remains in good alignment)
Chest
In older children and adults the abdomen should be flat
Abdomen
The front of the pelvis and the thighs are in a straight line. The buttocks are not prominent in back but slope slightly downward. The neck and lumbar spine should be in lordosis and the thorax and sacrum in kyphosis
Spine and pelvis (side view)
Ideally the body weight is distributed evenly on both feet and the hips are level
Hips, pelvis and spine (back view)
Legs are straight up and down, patella face straight forward, the knees are straight in the sagittal plane
Knees and legs
In standing the longitudinal arch has the shape of a half dome. The feet toe out slightly
Feet
Toes should be straight. They should extend forward in line with the foot and not be squeezed together or overlap.
Toes
You may have to prioritize what is important AND relevant as non-ideal posture does not
always result in significant or relevant dysfunction

From Kendall (4th ed. 1993) Be familiar with what muscles groups would be ELONGATED and
WEAK as well as those that are SHORT and STRONG
Gait and Functional Screening (*)
Gait:
Functional * screen: looking for REPRODUCTION of the patient’s asterisk sign or movement
which provokes “their pain”.
Functional quick neurological screen: (not to be used in substitution of a thorough and
complete neurological exam but can be quickly performed after watching the patient walk).
1. Single leg sit to stand (L3/L4)
2. Heel walk (L4/L5)
3. Toe walk (L5/S1)

Active physiological movement:
The main objective is to identify the asterisk or concordant sign. Positive findings may be used
as treatment. Overpressures are used to rule out joints. The concept of “centralization” may be
observed during your motion assessment of the spine. This is when the patient reports pain
arising from the spine and felt laterally from the midline that is reduced and transferred to a
more central or near midline position when certain movements are performed. If this occurs
during the first visit there is evidence to support that your patient may overall have a successful
outcome. When looking at physiological movement (flexion, extension, side bending and
rotation) it is recommended that the student follow the sequence below:
1. Have the patient stand in a standardized position (feet about 4-6 inches apart use your
foot to set the measurement).
2. Have the patient ACTIVELY move to the first point of pain (hold) and assess the response
(0-10 scale) if pain occurs prior to end range.
3. Have the patient then move past the point of pain (as long as they are comfortable and
able to do so) to their limit (hold) and assess the response (0-10 scale).
4. The patient then repeats the movement to determine if pain or range has changed while
the therapist again assesses their response.
If there is NO PAIN an OVERPRESSURE is applied. The use of overpressure is designed to “rule
out” potential movements and directions which may not be contributing to the patient’s
presentation. Overpressure is also performed as an attempt to reproduce the patient’s
concordant and or asterisk sign.

ACTIVE PHYSIOLOGICAL FLEXION
1. The patient is positioned in a neutral standing position and baseline symptoms are
assessed.
2. The patient is instructed to flex forward to his or her first point of pain and the pain is
questioned if it is their concordant sign.
3. The patient is then instructed to push past the initial point of pain and symptoms are
again questioned.
4. The patient is then asked to perform repeated movements past and or near the end
range of motion.
5. While performing the movement the patient is instructed to report whether his or her
symptoms are worsening, improving or staying the same (and or centralizing or
peripheralizing or neither). It is also imperative that you monitor to see if ROM has
changed as well.
6. If repeated flexion to end range was pain free, gently take up the slack on the last
repetition and apply firm pressure to engage the end feel.
7. Perform small oscillations at end range to rule out this motion.
8. If pain was present during flexion the overpressure is unnecessary.
If the repeated or sustained movements and overpressure are pain free the movement can be
identified as nonprovocative.

ACTIVE PHYSIOLOGICAL EXTENSION
1. The patient is positioned in a neutral standing position and baseline symptoms are
assessed.
2. The hands of the patient are placed on each side of his or her hips and baseline pain and
radicular/referred symptoms are reported.
3. The patient is instructed to bend backwards to his or her first point of pain and the pain
is queried to determine if it is their concordant or asterisk sign.
4. The patient is then instructed to progress past the first point of pain; symptoms again
are assessed.
5. The patient is then instructed to perform repeated movements past and/or near the
end range of motion.
6. While performing the movement, the patient is instructed to report whether his or her
symptoms are worsening, improving, or staying the same, and or
centralizing/peripheralizing, or neither. It is also imperative that you monitor to see if
ROM has changed as well.
7. If end range extension was pain free, gently take up the slack on the last repetition and
apply firm pressure to engage the end feel.
8. Perform small oscillations at end range to rule out this motion.
9. If pain was present during extension the overpressure is unnecessary.
If the repeated or sustained movements and overpressure are pain free the movement can be
identified as nonprovocative. Also if these movements do not demonstrate centralization it
may be helpful to assess the movements in prone.

ACTIVE LATERAL FLEXION (SIDE BENDING)
1. The patient is positioned in a neutral standing position and baseline symptoms are
assessed.
2. The hands of the patient are placed on each side of his or her hips and baseline pain and
radicular/referred symptoms are reported.
3. The patient is instructed to bend to his or her RIGHT / LEFT side to the first point of pain
and the pain is queried to determine if it is their concordant or asterisk sign.
4. The patient is then instructed to progress past the first point of pain; symptoms again
are assessed.
5. The patient is then instructed to perform repeated movements past and/or near the
end range of motion.
6. While performing the movement, the patient is instructed to report whether his or her
symptoms are worsening, improving, or staying the same, and or
centralizing/peripheralizing, or neither. It is also imperative that you monitor to see if
ROM has changed as well.
7. If end range lateral flexion was pain free, gently take up the slack on the last repetition
and apply firm pressure to engage the end feel. (PT standing to the side being
overpressed)
8. Perform small oscillations at end range to rule out this motion.
9. If pain was present during lateral flexion the overpressure is unnecessary.
If the repeated or sustained movements and overpressure are pain free the movement can be
identified as nonprovocative.

ACTIVE ROTATION in SITTING
1. To test rotation the patient is instructed to sit and cross tightly their arms on the chest
wall while sitting on the treatment table.
2. The clinician uses his or her knees to block the knees of the patient to reduce
compensation at the pelvis.
3. A baseline assessment in regards to pain is queried.
4. The patient is instructed to rotate as far as possible to the right side and pain is again
questioned specifically if it is their concordant or asterisk sign.
5. If pain free gently take up the slack and apply firm pressure to engage the end feel.
6. If end range rotation was pain free, gently take up the slack on the last repetition and
apply firm pressure to engage the end feel.
7. Perform small oscillations at end range to rule out this motion.
8. If pain occurred any time during the movement the overpressure is unnecessary.
9. Repeat on opposite side.

ACTIVE QUADRANT
1. The patient is positioned in a neutral standing position and baseline symptoms are
assessed.
2. The patient is then instructed to extend, rotate (right) and side bend (right) while the
symptoms are assessed.
3. This is then repeated for the left side
This can be a highly sensitive type technique but does not have the capacity to define the
specific origin of pain. A negative finding during the combined tests may be more useful than
a positive finding. It is useful to follow this active motion up with the seated rotation test
explained below.

Structural differentiation tests:
EXTENSION ROTATION TEST (Seated)
SN = 100
1. The patient is positioned in sitting position and the knees
are blocked as best possible. (may be modified according
to table height)
2. The patient is passively pushed into full extension.
3. The patient is then taken into full rotation on both LEFT
and RIGHT sides; while maintain full extension.
4. A positive finding is pain at end range extension and
rotation.
Notes:
Neurodynamic Assessment:
Sequencing of tests in order of least to most aggressive on the nervous system:
1. Passive neck flexion
2. Straight leg raise
3. Slump test
**PASSIVE NECK FLEXION (Supine) ** = A LMN neurological examination needed prior to performing
SN = Not reported
1. Passive neck flexion can be performed in two ways. Upper cervical flexion places the
load on the cervical and cranial meninges and if this is combined with lower cervical
flexion, a considerable load is placed right through the entire neuromusculature system.
2. This technique can frequently reproduce back pain suggesting nervous system
involvement. This is the preferred test to perform prior to SLR and SLUMP because it is
the least aggressive load on the nervous system and functions as a quick screen of their
current nervous system state.

Dr. Leal PT, DPT, OCS, FAAOMPT
**STRAIGHT LEG RAISE (Supine) ** = A LMN neurological examination needed prior to performing
SN = 97
1. Have the patient assume a supine position close to your side
of the plinth with both legs extended. This closeness allows for
improved patient handling during the technique. If you decide
to use a pillow under the head make sure you use it every time
to standardized your test position.
2. Stand facing your patient and place one hand under the ankle
avoiding pressure on the peripheral nerves where they are
superficial and place the other hand above the patella.
3. Keeping the knee extended flex the hip in a perpendicular
plane.
4. The patient’s trunk and hips should remain neutral avoiding any
internal or external rotation of the hips.
4. The leg is taken short of, to, or into sensory and or motor
responses depending on prior reasoned hypothesis of
pathobiological processes involved.
5. Be aware of symptom responses before, during and after the
technique.
6. A positive test is concordant reproduction of symptoms, positive sensitization (in this
case the use of passive neck flexion or passive ankle dorsiflexion to change either distal
or proximal symptoms), or overall gross asymmetry findings.

**SLUMP TEST (Seated) ** = A LMN neurological examination needed prior to performing
SN = 84
1. Starting position
The patient is sitting up straight and sitting with their
hips and thighs supported on the plinth with their knees
creases at the edge of the plinth. Ask your patient to put
their knees together and then relax their legs. Ask them
to link their hands together behind their back which will
keep the patient’s arms out of the way. Sit next to the
patient with your hands ready to guide the movement.
Assess symptoms.
2. Spinal slump
As your patient to then “sag in the middle of their spine”
while still looking forward and keeping their sacrum
perpendicular to the table. A small tactile cue of pushing on the stomach gently in the
posterior direction can help facilitate this if necessary. You won’t to avoid any pelvic
rotation as best as possible. Another great verbal cue is “keep tall while letting your
spine sag”. At this point there is no need for direct overpressure on the spine. Assess
symptoms.
3. Neck flexion
With the spine in this slumped position ask the patient to bend their head down or bring
their “chin to chest”. Watch their movement and imagine how much more the nervous
system is being loaded at this time. Tucking her chin in could also add more load to the
NS if needed.
4. Knee extension
Now have the patient extend their knee (usually non-affected leg first if the patient is
presenting with leg pain). Have them relax so that the ankle stays in a relative plantar
flexed position and not active dorsiflexed at this time. Take note of the patient’s
symptoms with this movement especially paying attention to if the non-affected leg
movement causes the opposite side symptoms to occur or worsen.

Dr. Leal PT, DPT, OCS, FAAOMPT
5. Release neck flexion
Have the patient then release neck flexion to “look up a little” using your hand to help
guide her neck and be aware of any change in symptoms. If a small amount of neck
flexion alters the patient’s lumbar spine or leg symptoms clearly the nervous system
could be “sensitive” at this time. You can refine the test by having her slowly extend her
neck back and at the same time check when symptoms change.
6. Extend knee
With the above position held ask the patient if they can straighten their knee any
further, this will often be the case. Check to see if it brings on symptoms again.
Additional modifications:
Ankle dorsiflexion = ankle and foot movements can easily be included in the
examination. A command such as “toes up towards your face” for dorsiflexion or “toes
to the floor” for plantar flexion is helpful directions for the patient in regards to
completing those movements. Ankle movements may be useful if the individual can full
extend their knee in regards to loading the nervous system as well as a movement for a
more proximal related issue.
Bilateral knee extension = after the patient has completed the routine slump it may be
worth asking the patient to extend both of their knees which will allow the therapists to
compare left versus right. It is important to remember that this as well is a progression
from the standard slump in regards to loading the nervous system a bit more
aggressively.

Passive Accessory Intervertebral Motion (PAIVM):
PALPATION (PRONE): (Always start with this)
1. Have the patient positioned in supine and skin exposed for an overall scan of the
tissue and palpation assessment. Head needs to be supported in a neutral position.
2. Use the palmar aspects of your hands to sweep up and down the lumbar spine area
feeling for muscle bulk / atrophy as well as temperature, sweat, and overall coloration
or any discoloration of the tissue. This is a good introductory for you to have with your
patient in regards to touch. Be sensitive to cold hands and the position of the patient
(prone unable to view what is going on). Assess symptoms as needed.
3. Palpate the following: QL (left and right), ES (left and right), and the supraspinous as
well as iliolumbar ligaments. Note any differences left versus right and assess for
symptoms.
4. Palpate the iliac crests and then find the spinous process of L4.
Notes:
PASSIVE ACCESSORY INTERVERTEBRAL MOTION (PAIVM): Central PA
1. The patient is placed in prone with their hands down at
their sides and their head in a neutral position. Palpate
the iliac crests to then move across the midline part of
the body to find the spinous process of L4. Once at L4
count upwards to L1; this will be your starting point.
2. Once at L1 place the pisiform of one hand on the spinous
process of L1.Then take your other hand and intertwine it as
shown in the picture to the right. Your elbows should be
straight and your head / trunk should be directly over your
arms and over the L1 segment. You should be able to “look
straight down” at the L1 segment with your head over the
opposite side of the patient’s trunk. Assess for symptoms.
3. Once in this position the clinician applies ~ 4kg of force (blanching of your fingernail
if pushing down on the plinth) while at the same time assessing for symptoms and
or a response to the applied pressure. The pressure should be light first followed by
progressive intensities.

Dr. Leal PT, DPT, OCS, FAAOMPT
4. The clinician continues from distal to proximal on the patient’s spine again assessing
for symptoms (specifically the patient’s asterisk sign if possible) as he or she assess
each segment.
5. The clinician attempts at each segment to make a decision regarding if the movement
is: NORMAL, HYPOMOBILE, or HYPERMOBILE often times in relationship to each of the
other segments.
6. The clinical is encouraged to assess tissue movement through various GRADES OF
MOVEMENT as established by Maitland (see below):
GRADES OF MOVEMENT REVIEW:
A system of graded movements (I, II, III, IV, V) is used to describe where this motion takes
place within the continuum of the overall total motion of the joint.
Grade I: small amplitude movement performed at the beginning of range.
Grade II: large amplitude movement performed within a “resistance-free” part of range.
Grade III: large amplitude movement performed “into resistance” or up to the limit of range.
Grade IV: small amplitude movement performed well into resistance.
Grade V: To be discussed in Ortho (DPT 707)
Concept of R1/R2 (Maitland): Resistance to movement may manifest as a loss of the friction-
free feeling through range of stiffness, increasing as the movement is carried further into range.
The term R1 is used to represent the onset of resistance and R2 to represent the quality of
resistance which acts to limit range of motion.

PASSIVE ACCESSORY INTERVERTEBRAL MOTION (PAIVM): Unilateral PA
1. The is similar to the central PA as mentioned above but you are
now applying pressure and assessing left and right sides
independently. This unilateral pressure is directed towards the
right facet, lamina and transverse process (one motion) of each
lumbar vertebra and then the other side is assessed in a similar
fashion.
2. Find L1 as you did previously. Once at L1 place a thumb pad to
thumb nail contact. The clinician then applies a gentle force
perpendicular to the targeted transverse process of the lumbar
spine (right or left).
3. Once in this position the clinician applies ~ 4kg of force (blanching of your fingernail
if pushing down on the plinth) while at the same time assessing for symptoms and
or a response to the applied pressure.
4. The clinician continues from distal to proximal on the patient’s spine again assessing
for symptoms (specifically the patient’s asterisk sign if possible) as he or she assess
each segment.
5. The clinician attempts at each segment to make a decision regarding if the movement
is: NORMAL, HYPOMOBILE, or HYPERMOBILE often times in relationship to each of the
other segments.
6. The clinical is encouraged to assess tissue movement through various GRADES OF
MOVEMENT as established by Maitland (see section above for details).
Notes:
Summary for PAIVM’s:
It may yield useful information in the detection of lumbar pathology
It is useful in isolating the dysfunctional segment (pain)
May be reliable when assessing pain but not as reliable when reporting or assessing
“Stiffness only”
IIs beneficial when pain provocation is the purpose of the segmental examination
Necessary “last part” when clearing the lumbar spine
