Shoulder Flashcards
Frozen shoulder
Adhesive capsulitis is often more prevalent in women, individuals 40-65 years old, and in the diabetic population, with an occurrence rate of approximately 2-5% in the general population, [5][2][8][9][4][10] and 10-20% of the diabetic population.[9][10] If an individual has adhesive capsulitis they have a 5-34% chance of having it in the contralateral shoulder at some point. Simultaneous bilateral involvement has been found to occur in approximately 14% of cases.[2] Other associated risk factors include: trauma, prolonged immobilisation, thyroid disease, stroke, myocardial infarcts, and presence of autoimmune disease.[5][11]
patients with adhesive capsulitis commonly present with ROM restrictions in a capsular pattern. A capsular pattern is a proportional motion restriction unique to every joint that indicates irritation of the entire joint.[20] The shoulder joint has a capsular pattern where external rotation is more limited than abduction which is more limited than internal rotation (ER limitations > ABD limitations > IR limitations).[20][22] In the case of adhesive capsulitis, ER is significantly limited when compared to IR and ABD, while ABD and IR were not seen to be different.
