Symptoms:

acute pain in the left anterior deltoid
back pain (sometimes but not always)

Visual assessment:

The right hip is higher with internal rotation of the left femur and compensatory external rotation of the left tibia. This would insinuate lengthened left medial hamstrings and popliteus, lengthened posterior fibres of the left gluteus medius and lateral rotators of the left hip.

Hypertrophy of the left thigh.

The left scapula is abducted/medially rotated. The left glenohumeral joint appears to be medially rotated although this may be the result of the medially rotated scapula. Efforts should focus on adducting the left scapula to be symmetric with the right scapula and to see if this apparent glenohumeral medial rotation resolves itself.

Treatment:

Primary exercises should focus on Adducting the left scapula and laterally rotating the left femur.  After 4 weeks exercises should extend to the medial hamstrings. Once the left scapula is maintained in a more adducted position, the glenohumeral joint can be assessed and appropriate rotator cuff exercises can be prescribed.

The higher right pelvis stretches the right abductors as the right hip is held in relative adduction, exercises should focus on creating tension in the right abductors at a shortened position. This may resolve the back pain.

Exercises:

Perform 1 set of exercises on the right and 3 sets on the left side- 8-12 reps twice a week

Left Single arm rows with scapula held in a stabilised position

Clams on left

Stretch left pec minor

Lower trapezius to reciprocally inhibit he pec minor
