Comparison of the effectiveness of posterior capsule stretching and posterior mobilisation on subacromial impingement syndrome

Subacromial Impingement Syndrome is one of the most common shoulder pathologies causing shoulder pain, functional disability and reduced quality of life. Our study is designed to investigate the effectiveness of posterior capsule strecthing and posterior mobilisation on shoulder joint functions in Subacromial Impingement Syndrome. 50 patients with SIS and 30 healthy individuals are included in our study. The introductory characteristics of cases with sociodemographic survey, pain intensity with VAS, upper extremity function with American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form and Modified Constant Murley Score, upper extremity disability and health situation with Quick Disability Arm, Shoulder and Hand Score, the evaluation of musculoskeletal symptoms with Cornell Musculoskeletal Discomfort Questionnaire, range of motion with goniometer, shoulder muscle strength with myometer, grip strength with dynamometer and pinchmeter and posterior capsule tightness with tapeline. Individuals were divided into 3 different groups as posterior mobilisation, posterior capsule and control group. While individuals included in the mobilization group were given classical stretching and strengthening and home exercise programs in addition to posterior mobilization, for the capsule stretching group, classical stretching and strengthening and home exercise program were given in addition to posterior capsule stretching exercise and no exercise program was given to the control group and only posterior capsule tightness evaluation was applied. In our study, while there were found statistically significant difference between both groups in the Constant score and involved part External Rotation range of motion (p<0,05), statistically significant difference was not observed in the evaluation of muscle strength, grip strength and posterior capsule tightness (p>0,05). It was seen that in the individuals applied mobilisation, the functional capacity of the shoulder joint were increased more than according to those of the capsule stretching.
