Subacromial Impingement Syndrome is one of the most common shoulder pathologies causing shoulder pain, functional disability, and reduced quality of life. This study investigated the effectiveness of posterior capsule stretching and posterior mobilization on shoulder joint functions in Subacromial Impingement Syndrome.~74 patients with SIS were enrolled, 58 were included, but 50 completed the study. Also, 30 healthy individuals were included and completed the study. The introductory characteristics of cases with the 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 a goniometer, shoulder muscle strength with myometer, grip strength with dynamometer and pinch meter and posterior capsule tightness with a tapeline. Individuals were divided into three different groups posterior mobilisation, posterior capsule, and control group. While participants 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 this study, while there was found a statistically significant difference between both groups in the Constant score and involved part External Rotation range of motion (p<0,05), a statistically significant difference was not observed in the evaluation of muscle strength, grip strength and posterior capsule tightness (p>0,05). In the participants who applied mobilization, the functional capacity of the shoulder joint was increased more than those of the capsule stretching.
