  1. GP LECTURE SERIES 2013 THE SHOULDER Assessment, treatment and functional considerations

  2. Basic rotator cuff anatomy and function • Dynamic stability of the glenohumeral joint • The RC tendons blend together to become the joints capsule • Allows for increased mobility but compromises stability • Shallow glenoid fossa supported by a cartilaginous labrum cover • RC’s aim to maintain the HOH in optimal contact with the glenoid fossa throughout range

  3. 3D assessment • Upper and lower fibres of trapezius work together to E/IR the scapula • Serratus anterior keeps the medial border of the scapula in close contact with the thorax • If 1 or more of these forces become under/over active abnormal shoulder, neck or back mechanics could result

  4. Thoracic spine and shoulder function • Compensatory thoracic spine E, rot and LF to allows for more arm elevation • Hypomobile/stiff spinal and rib joints mean more movement needs to take place at the GHJ • Increase kyphosis protracts the scapula causing an imbalance throughout the shoulder girdle

  5. Poor sitting posture & ergonomics

  6. Looking at the bigger picture • The shoulder and thoracic spine can also be affected by structures way down the kinetic chain • Core strength and posture are very important and need to be addressed • Often diagnosing a shoulder condition is simply the symptom of a much bigger cause

  7. Hawkins Kennedy Test • Test for impingement and bursal bunching • Position for testing: Arm abducted to 90 degrees the examiner administers a downward pressure on the forearm into internal rotation whilst stabilising the humerus.

  8. Full/Empty can test • Test for supraspinatus/infraspinatus tear/tendonitis • Position for testing: Patient in standing or sitting abducts arms to 90 degrees. • Supraspinatus; empty can • Infraspinatus; full can

  9. Apprehension Test • Test for anterior instability or recent shoulder dislocation/subluxation • Position for testing: patient lies in supine with shoulder abducted at 90 degrees and in maximal external rotation. The humerus is supported and overpressure into external rotation administered. • The anterior capsule should be supported and then overpressure released to confirm instability

  10. Crank-pivot test • Designed to identify a labral tear or SLAP lesion. • Position for testing: Patient in supine, arm in external rotation, examiner compresses the humeral head into the glenoidfossa and pivots the arm back and forth.

  11. Frozen shoulder • Related to a loss of range throughout all degrees of freedom in the shoulder – need to look at all AM’s • External rotation most affected followed by abduction and then flexion • Particular attention should be taken to look at the scapula - sometimes range may seem equal both sides, but this is only being achieved by excessive compensatory scapulothoracic joint movement rather than normal glenohumeraljoint function

  12. Physiotherapy and Shoulder Disorders • Analysis of the results and effectiveness of exercise across all available clinical trials demonstrates that Physiotherapy exercises for mixed shoulder disorders & rotator cuff diseases are effective at; • Reducing pain • Improving muscle strength • Increasing function • Improving general well-being • Unsurprisingly the longer the patients performed the prescribed exercises the greater the reduction in their pain (Green, Buchbinder & Hetrick 2013)

  13. Shoulder Impingement • Manual therapy applied by experienced physical therapists, combined with a supervised exercise programme was found to be better than exercise alone for patients with shoulder impingement syndrome in; • Increasing strength • Decreasing pain • Improving function (Bang & Deyle, 2000)

  14. Frozen Shoulder • No evidence that Physiotherapy, Pharmaceutical intervention or corticosteriod injections change the outcome of idiopathic frozen shoulder (Brukner & Khan 2006) • However, early range of motion exercises and education on the pathway of frozen shoulder are effecting in restoring range, relieving pain and improving function (Brukner & Khan, 2006) • It is also important to correct secondary complications that may arise from having a stiff and painful GHJt
