Degenerative arthrosis of the shoulder (omarthrosis) is less commonly diagnosed than at the joints of the lower extremity. The shoulder joint does not have to bear weight and some of the mechanical stresses are taken up by the subacromial space. However, anatomical studies reveal a significant incidence of degenerative changes at the glenohumeral joint with increasing age. Arthrosis is caused by mechanical loading, rotator cuff defects, and abnormal joint motion following surgery. Clinical symptoms vary widly. Acupuncture, laseracupuncture and in advanced degenerative situations PRP ( platelet rich plasma) and interstitial PBM (photobiomodulation) can often achieve terrific clincial results.
