Abstract

Background Adhesive capsulitis (AC) is characterized by a painful, gradual loss of both active and passive glenohumeral motion resulting from progressive fibrosis and ultimate contracture of the glenohumeral joint capsule. Fibrosis of the glenohumeral joint capsule can effect proprioception by stimulating mechanoreceptors.

Objectives The aim of this study is to investigate the effect of capsular tightness on proprioception in patients with Adhesive Capsulitis.

Methods Twenty five patients with adhesive capsulitis (21 female, 4 male; mean age 53±6 years; age range 44-67) were included in this study. Mean Body Mass Index (BMI) was 29.02±4.89. 11 dominant and 14 nondominant shoulder was measured. Proprioception was assessed with active repositioning process by inclinometer. Flexion, scapular elevation and rotations were assessed at mid range (MR) and end range (ER). Capsuler tightness (superior and mid fibers of posterior capsule, posterior capsule general, glenohumeral ligament (GHL)) was measured by a ruler and a universal goniometer. Relationship between proprioception and capsular tigtness was determined by Pearson correlation analysis.

Results There was a significant, moderate and negative relationship between proprioception of external rotation at MR and ER and GHL (superior, middle and inferior GHL complex) tightness (p<0.05). There was a significant, moderate and negative relationship between proprioception of external rotation at ER and general posterior capsule tightness (p<0.05) ( Table 1).

Conclusions In this study, our results showed that enhancement in tightness of capsule and GHL in patients with adhesive capsulitis increases proprioception of external rotation at MR and ER. This means that mechanoreceptors located within joint capsule are more sensitive at these ranges. Decreasing or eliminating tightness of capsule and GHL in patients with adhesive capsulitis may supply restructuring proprioception at normal range of motion.
