ABSTRACT

The patient main complaint was the inability of continuing playing volleyball at a semi-professional level. A 28-year-old semi-professional volleyball player with a 5 week history of right anterior-superior shoulder pain aggravated by performing volleyball “spike”, free weights chest press, with discomfort at full rom in flexion, resisted abduction and external rotation, with reverse scapulohumeral rhythm, positive on impingement tests.

Risk Factors and sports specific aspects

Shoulder injuries amongst volleyball athletes are mainly reported to result from overuse possibly leading to rotator cuff tendinitis, coracoacromial impingement and glenohumeral joint instability. In an epidemiological study amongst 295 volleyball players, Aagaard and colleagues (1) reported 286 injuries with an incidence of 4.2 injuries every 100 hours of playing. The most frequent injuries were acute injuries located in the ankle and finger and overuse injuries in the knee and shoulder, which occurred mostly during blocking and spiking.

The risk factors associated with the recurrence of shoulder pain are linked to:

Overuse during training
Poor shoulder mobility
Muscle imbalance, specifically between internal and external rotators
Muscle weakness
Scapular dyskinesis

The implication for the patient was to modify his training regime and stop his participation to games. It is paramount to diagnose the injury in time and produce an appropriate treatment plan with a specific gradual return to training.

Examination

Inspection

Static scapular malposition compared to the non-affected side.
Dropped scapula due to scapular protraction, lateral displacement and abduction.
Moderate scoliosis with right thoracic and left lumbar curvatures.
Anteriorly, apparent inferior position of the lateral clavicle due to scapular protraction.

ROM

Reverse scapulohumeral rhythm with shoulder elevation and excessive scapular lateral tilt after 60° of abduction
Full flexion with increased shoulder elevation after 75°
Full external rotation with discomfort at the end of range

Resisted tests

Abduction combined with external rotation against resistance was painful (VAS 7/10) and weaker than left side
External rotation and abduction when tested singularly did not reproduce symptoms
Scapular retraction with rhomboids activation was weaker on the right side and position could not be maintained for 10 seconds

Palpation

Tenderness on the coracoid medial aspect, at the point of insertion of the pectoralis minor tendon.
Tenderness on the superior scapular border at the attachment of the elevator scapulae
Acromioclavicular ligament discomfort

Scapular assistance test

Laterally and upward manual assistance of the inferior medial scapular border to simulate the serratus anterior/lower trapezius portion of the elevation force couple.
Discomfort at the end of range was not present when technique applied

Other

Empty-can test for rotator cuff integrity: mild discomfort.
Neer test for impingement: positive at full internal rotation
Kennedy-Hawkins test for impingement: positive.
Acromioclavicular shear test: positive

Rehabilitation

Rehabilitation is based on a proximal to distal regain of motion, control, and strength.

SMART GOALS

Proximal Scapular Control And Strength 35%

Antagonist Musculature Increase In Flexibility 50%

Correction Of Postural Dysfunction 35%

Decreasing Symptoms 40%

Rehabilitation Plan

Avoidance of painful exacerbating movements (volleyball spike, chest press) and fatigue of the scapula-humeral/thoracic muscles.
Initiation of closed kinetic chain (CKC) activities in order to reproduce or provide proprioceptive stimulation to joint mechanoreceptors which helps to reorganize and re-establish normal muscle firing patterns.
CKC activities can include weight shifts, scapular clock, rhythmic ball oscillations and wall-push ups.

Inclusion of activities which involve using of hip and trunk musculature (mass movement patterns) such as trunk strengthening: abdominal crunches and/or prone upper/lower extremities opposition for para-spinals; trunk extension with lateral rotation facilitates scapular retraction.
Scapular retractions combined with massage to reduce contracture of coracoid based muscles.
Myofascial release near anterior clavicle or delto-pectoral triangle
Manual stretching of scalenes, elevator scapulae, pectoralis minor.
“Sleeper” stretches to stretch posterior capsule and posterior rotator cuff muscles
Interval volleyball training can commence including aerobic training, ball activity with partners, sprinting and change in direction.

Recovery Phase (3 –7 weeks)

SMART GOALS
Proximal scapular control and strength 70%
Antagonist musculature increase in flexibility 75%
Correction of postural dysfunction 60%
Decreasing symptoms 70%
Return to volleyball training 50%

Begin with concentric/eccentric contractions.
Standing external rotation (ER) with theraband (towel roll under axilla cueing patient to avoid trunk rotation); side lying ER

Serratus anterior punch/press into wall with pillow or deflated ball (standing, arm neutral at side elbow in 90° of flexion). Progression to arm at or just below 90°
Seated rows emphasizing setting of the scapula prior to each repetition, finishing each set in retraction
Lower/mid trapezius activation in prone with progression to different upper limb positions.
Interval volleyball training can commence including aerobic training, ball activity with partners, sprinting and change in direction.

Maintenance Phase (7 – 10 weeks)

SMART GOALS:
Proximal scapular control and strength 90%
Antagonist musculature increase in flexibility 90%
Correction of postural dysfunction 80%
Decreasing the symptoms 95%
Return to volleyball training 100%

At this stage, the patient must have good scapular control and motion throughout range of shoulder motion in order to progress to full athletic activities.

Ply metric with medicine ball to dynamically challenge scapular stabilizers. The weight of the ball provides an eccentric stretch, which is then converted to a concentric contraction. Progress to unilateral throwing of smaller weighted medicine balls or bilateral overhead ball toss against a spring trampoline.
Modified push-ups.

Chair push ups or seated dips.

‘Scaption” arm in 30 – 45° abduction.
Rhythmic stabilization of rotator cuff muscles.
Return to volleyball training, with gradual return to spiking ad serving and interval competitive matches.

Evidence base

Strengthening Training:

Shoulder muscle imbalance and weakness, low shoulder rotator muscle strength ratios and weak external rotators are possible shoulder injury risk factors for overhead athletes. In the dominant arm, the volleyball players had significantly higher concentric peak torque of the internal and external rotators at both velocities, and significantly higher eccentric peak torque of the shoulder internal and external rotators than the controls. In a similar study by Forthomme and colleagues (4), spike velocity correlated significantly with strength performance of the dominant shoulder rotator muscles. In acceleration, however, these muscles behaved independently; activity of the teres minor remained high, whereas the activity of the infraspinatus declined. The anterior wall muscles functioned to decelerate the humerus during cocking and acted as internal rotators during acceleration. Muscle activities recorded for the serve followed similar patterns as those seen for the spike, but with lower amplitudes. In the specific clinical scenario presented in this report, a strength-training regime was designed for the patient taking into account his needs. Weakness of the external/internal rotator muscles and scapular stabilizers was addressed through a strengthening programme incorporating concentric and eccentric activation patterns and was progressed to include sport specific drills.

Scapular Stabilizers Training

Scapular malposition is thought to be related to shoulder impingement by narrowing of the subachromial space. Scapular dyskinesis was also associated with excessive protraction and decreased cocking and elevation, which can effectively alter volleyball specific biomechanics. The athlete in this case scenario presented a scapula infera with lateral displacement. A specific training regime was designed to retrain scapular stabilizers in an isometric fashion and was progressed to include concentric and eccentric activation patterns with sport specific drills. Since the scapula plays a vital role in the volleyball spike as it acts as a stable base for origin of the muscles that control arm movement and provide glenohumeral compression, scapula position and control training is paramount during rehabilitation and as part of a preventative exercise regime. Rehabilitation protocol aimed to restore scapular musculature balance produced significant changes of glenohumeral internal rotation, increase in rotator muscle strength and decrease in pain scores, which seem to confirm the role of a proper scapular position for an optimal length–tension relationship of the RC muscles.
