Prevention

• Injuries are prevented by:

• Identifying risk factors

• Addressing risks with preventive measures

Posture

Muscle Imbalance

Muscle

Imbalance

Altered Reciprocol

inhibition

(Altered length-tension )

Synergistic

Dominance

(Altered force-

couple)

Arthrokinetic

Dysfunction

(Altered Joint function)

Dysfunction

• Altered reciprocal inhibition- a tight muscle causes decreased neural drive to its functional antagonist

• Synergistis dominance- compensation of synergistic muscles in order to maintain force production

• Myofascial dysfunction (trigger points)

• Arthrokinematic dysfunction- joint dysfunction affecting the surrounding muscles

• Faulty movement patterns

Dysfunction Leads to

• Altered neuromuscular control

• Tissue fatigue

• Injury and impaired performance

Causes of Muscle Imbalances

• Postural stress

• Pattern overload

• Repetitive movement

• Lack of core stability

• Lack of neuromuscular efficiency

Muscle Imbalance

• The relationship between the tone or strength and

length of the muscles around a joint

• Stronger will shorten and the opposite will lengthen

• Weakness causes faulty alignment or an imbalance

• Bilateral and unilateral

• Common example is low back pain can be contributed to a

weak abdomen

PATTERNS OF DYSFUNCTION

When a chain reaction evolves in which some

muscles shorten and others weaken, in predictable

patterns of imbalance (Janda)

1. Upper crossed syndrome

2. Lower crossed syndrome

Cumulative Injury Cycle

Muscle Imbalance

Altered Neuromuscular Control

Muscle Spasm - Adhesions/Trigger points

Tissue Trauma

Inflammation

Screening

• To recognize candidates for possible injury

• Manual Muscle Testing

• A muscle is isolated and tested for strength

• Muscle length

• Stretched to endpoint

Strengthening

• The agonist needs to be lengthened

• The antagonist needs to be trained to work again or strengthened

• Statically then dynamically

• Static requires both the agonist of that movement to be strengthened and the antagonist of that movement to be stretched lengthening the muscle

• Dynamic exercises can be done in a variety of ways to contribute to the benefits needed

Prevention

• Education

• Proper posture

• Proper and equal weight lifting

• Hamstring vs. quadriceps muscles

• Stretching

Weaknesses Usually Found

• Hip Stabilizers (gluteus medius, adductors, quadratus

lumborum, hip external rotators)

• Lumbar Stabilizers (transverse abdominus, internal

obliques)

• Scapular Stabilizers (lower traps, rhomboids)

In Other Words… “The Core”

• Evolving concept of trunk strength & stability

• “Pillar” a more inclusive concept, more than just the

abdominals

• It is the integration of the hips, trunk and shoulders

Some other roles of the

Core

• Posture

• Balance

• Energy transfer (LB to UB & vice-versa)

• Protection (internal organs)

• Anchoring (muscle origins & insertions)

FUnctional Assessment

What is Function? • Function – from Latin

“functio” meaning to perform, the special action or physiologic property of an organ or other part of the body (Stedman’s)

• What constitutes lower extremity “function”?

– Speed

– Agility

– Hopping

– Jumping

– Landing

– Balance

– Proprioception

– Stability

– Strength

– Muscle Reaction Time

– Joint Laxity

– Kicking

– Subjective considerations

Ultimate Rehabilitation Goal

• Return the

athlete/patient to the

highest functional level

in the most efficient

manner!

Functional Performance

Testing • Can assist the clinician in making

return to play decisions

• “These tests are designed to

simulate, in a controlled manner,

the stresses produced and

imposed on the LE during athletic

participation” – Drouin and Riemann -

ATT 2004

• The outcome measure is a

summary variable that represents

a patient’s sensorimotor function,

muscle strength and power,

flexibility, pain, and confidence

Concepts of Functional

Rehabilitation

• Begins on the day of injury and continues until pain-

free gait & activities are achieved!

• Four Aspects of Functional Rehabilitation:

• ROM

• Strengthening

• Proprioception

• Activity-Specific Training

Lower Extremity

Functional Testing • Balance Tests

• Numerous variations of

the Romberg test are

available

• Valid and reliable

• Scoring may include time

or use of the Balance

Error Scoring System

(BESS)

• Can be performed on a

variety of surfaces

The BESS

Reliable with SL and TS on a firm

surface, and DL, SL, and TS on a foam

surface!

Lower Extremity

Functional Testing • Balance Tests

• Star Excursion Balance Test (SEBT)

• Reliable (Kinzey & Armstrong 1998 – JOSPT, Hertel et al. 2000 – JSR)

• A test of dynamic stability (strength, hip, knee, & ankle ROM, proprioception, NM control) as an alternative to those involving a quiet stance

• Goal is to reach as far as possible with one leg in each of 8 directions while balancing on the contralateral leg

• Three reaches in each direction are averaged

• Posteromedial reach is highly representative of all 8 components! (Hertel

Functional Movement

Screening

What is FMS? • Series of movements designed to

screen for:

Flexibility

Body movement asymmetry

Core muscle weakness

• Screening can potentially predict injury

If we can predict it, we can prevent it

• Find the weak link and fix it!

• Less Injuries =

Decreased training losses

Better soldier retention

What is FMS? • 7 fundamental movement patterns

• Graded by trained examiner

• Each movement graded 0 to 3

• Able to target problem movements

• Creates individual functional

baseline

• Simple, quick, reproducible

• Deficits corrected by physical

therapy program

7 Movements

• Deep Squat

• Hurdle Step

• In-Line Lunge

• Shoulder Mobility

• Straight Leg Raise

• Push-Up

• Rotational Stability

Summary

• Certain physiologic measures are good indicators of

performance

•Many performance tests can be conducted

•Multiple variations of training programs can be

devised to improve performance

• All energy systems should be trained.
