Effects Of Subscapularis Muscle Soft Tissue Mobilization On Pain And Functionality In Shoulder Dysfunction

Abstract

Purpose: Tightness of the subscapularis muscle causes glenohumeral external rotation limitation and difficulties in over-head activities. This study aimed to determine the effects of soft tissue mobilization applied to the subscapularis muscle on pain and functionality in shoulder dysfunctions.

Methods: The 48 patients with shoulder pain and limitation were included in the study. They were randomly divided into conventional physiotherapy program (CPP) group (n=25) and soft tissue mobilization (STM) group (n=23). The first group received CPP and the second group received STM. All patients had treatment at a physiotherapy clinic for 15 sessions. The pain was evaluated using Visual Analogue Scale (VAS), shoulder joint movements were measured using a goniometer and overhead reach test, and functionality was evaluated using the Shoulder Pain and Disability Index (SPADI). The patients were assessed before, immediately after, and three weeks after the treatment.

Results: Statistically significant improvements were found in VAS, shoulder flexion and extemal rotation range of motion, and overhead reach test in both groups immediately after treatment and at the end of the 3rd week (p<0.05). When groups were compared after three weeks, statistically significant improvements were found in VAS, external rotation range of motion, and overhead reach test in the STM group (p<0.05). There was a statistically significant improvement in SPADI in both groups after the treatment (p<0.05). There was no significant difference in SPADI score between the groups (p>0.05).

Conclusion: The STM was more effective on pain, range of motion, and functionality than CPP. STM of subscapularis muscle might be an alternative treatment of the shoulder dysfunction.
