There are probably 30 or more tests just for labrum tears of the shoulder. Many seem to be minor variations on a theme. Which ones have been tested and shown to be of value?
What about instability and rotator cuff tears?
Are there conservative approaches that work for shoulder problems?
What are the best tests for specific shoulder problems?
Impingement Syndrome
In the Park et al. study, 913 patients underwent physical examination and diagnostic arthroscopy
The combination of the Hawkin's-Kennedy, painful arc, and infraspinatus muscle tests yielded the best post-test probability (95%) for any degree of impingement

Rotator Cuff Tear
In a retrospective study by Ito et al. common sites of pain were evaluated using clinical charts of 149 patients diagnosed with either rotator cuff tears or adhesive capsulitis confirmed by arthroscopic findings
The lateral and anterior shoulder were the most common sites of pain regardless of the existence of whether there was a tear or where the tear existed.
Motion pain was more common than pain at rest for patients with rotator cuff tendonitis or tears.
The authors conclude that pain location is not useful in locating the site of a tear, however, the physical exam based on positive results to muscle tests with appropriate thresholds for muscle weakness was clinically useful.
The combination of the painful arc, drop-arm sign, and infraspinatus muscle test produced the best post-test probability (95%) for a full-thickness rotator cuff tear.

Glenoid Labrum Tears
The diagnostic accuracy of individual tests without Hx findings is poor to moderate
The combination of popping/clicking with a positive Crank OR Anterior Slide result
OR
• A positive Anterior Slide with either a positive Active Compression OR Crank test result indicates a labral tear
• The absence of popping/clicking or absence of a positive Anterior Slide or Active Compression test suggests the absence of a labrum tear

Manipulation and exercise for management of shoulder pain
In a Cochrane review by Green et al. (2003) exercise was demonstrated effective for short-term recovery in rotator cuff disease (RR 7.74 [1.97,30.32]) and a benefit for long term restoration of function (RR 2.45 [1.24, 4.86]).
For rotator cuff disease a combination of exercise and mobilization resulted in additional benefit over exercise alone
Green S, Buchbinder R, Glazier R, Forbes A. Interventions for shoulder pain. Cochrane Database Syst Rev; 2000:CD001156.
In the Desmeules systematic review (2003), exercise or manual therapy were evaluated
Four studies (rating of 67% for top three) suggested some benefit for therapeutic exercise or manual therapy when compared with other treatments such as acromioplasty, placebo, or no intervention
Desmeules F, Fremont P. Therapeutic exercise and orthopedic manual therapy for impingement syndrome: a systematic review. Clinical Journal of Sport Medicine. 2003;13(3):176
Bang et al. performed an RCT with patients diagnosed with impingement, rotator cuff tendonitis, or “shoulder tendonitis”, and randomized them into two treatment groups
The first group received supervised flexibility and strengthening exercises while the second group also received the same flexibility and strengthening program but also received manual therapy. Both groups received their respective interventions 6 times over a three week period.
Subjects in the combined treatment group (manual therapy plus exercise) had significantly more improvement in pain and increases in function although both groups had some improvement. Strength in the manual therapy group improved significantly while not in the exercise group!
Manual therapy as described in this study included “gliding” mobilization, not manipulation
Bang MD, Deyle GD. Comparison of supervised exercise with and without manual physical therapy for patients with shoulder impingement syndrome. J Orthop Sports Phys Ther. Mar 2000;30(3):126-137.
In an RCT assessing the effect of a standardized 8 week home exercise program on workers diagnosed with shoulder pain, Ludwig et al. randomized 67 male workers diagnosed with impingement syndrome into either the at-home exercise group or a no treatment control group
The intervention group showed significantly greater improvements in the Shoulder Rating Questionnaire and shoulder satisfaction score compared to the control group.
