Background It is necessary that coordinated, synchronous motion of humerus, scapula and clavicula for full shoulder mobility and function. This motion may be impaired by adhesive capsulitis (AC) which is characterized by fibrosis and contracture of the glenohumeral joint capsule and ligaments.

Objectives In this study we aimed to assess scapular biomechanics in patients with adhesive capsulitis and determine changes.

Methods Twenty five patients with AC (21 female, 4 male; mean age 53±6 years; age range 44–67) and twenty five healthy people (21 female, 4 male; mean age 51±7; age range 39–65) were included in this study. Mean Body Mass Index (BMI) was 29.02±4.89 in AC group (ACG) and 28.40±4.67 in healthy group (HG). 11 dominant and 14 non-dominant shoulders in ACG and 12 dominant and 13 non-dominant shoulders in HG were measured. Kibler's observational classification system and lateral scapular slide test (LSST) were used for evaluating scapular position and mobility.

Results There were 2 type I, 8 type II,10 type III and 5 symetric scapula in ACG and 3 type I, 4 type II,7 type III and 11 symetric scapula in HG. 80% of ACG and 56% of HG had scapular dyskinesia but it was not significant (p>0.05). There was significant difference between groups in LSST the distance between inferior angle of scapula and T7 at 90° abduction (p<0.05) (Table 1).

Conclusions In this study, our results showed that scapular biomechanics were impaired in patients with AC. Especially the majority of type III scapula and the distance between inferior angle of scapula and T7 at 90° abduction demonstrate increase in scapular upward rotation in upper degrees of elevation.
