Based on the absence of a significant correlation between jointspace capacity and restricted shoulder
ROM, contracted soft tissue around the shoulder may be related to restricted shoulder ROM. Vermeulen
and colleagues indicated that adherent axillary recess hinders humeral head mobility, resulting in diminished mobility of the shoulder. Furthermore, they documented that abnormal scapular motion existed in patients with FSS despite improvement in glenohumeral motion following a 3-month period of physical therapy intervention. Apparently, impaired shoulder movements affect function. In longitudinal follow-up studies lasting from 6 months to 2 years, significant numbers of patients with FSS demonstrated moderate functional deficits.
