Shoulder Pain Syndrome

This study aims to compare the effects of concentric and eccentric full can exercises on supraspinatus muscle architecture in individuals with partial rotator cuff tears. Rotator cuff tears are a common cause of shoulder pain and functional limitation. The supraspinatus muscle plays a key role in shoulder movement and stability, and its structure may be affected in individuals with partial tears. Exercise-based rehabilitation is widely used in the conservative management of these conditions. The full can exercise is commonly prescribed to selectively activate the supraspinatus muscle. However, the effects of different contraction types, specifically concentric and eccentric exercises, on muscle structure and clinical outcomes are not fully understood. In this study, participants will be randomly assigned to either a concentric or eccentric full can exercise group. Both groups will receive a standard physiotherapy program, including therapeutic ultrasound and transcutaneous electrical nerve stimulation (TENS), in addition to the assigned exercise protocol. The intervention will last for 6 weeks, with sessions performed three times per week. Outcomes will be assessed before and after the intervention. The primary outcome is the change in supraspinatus muscle pennation angle measured by ultrasound imaging. Secondary outcomes include muscle architecture parameters, pain intensity, range of motion, muscle strength, functional status, and kinesiophobia. The findings of this study may help improve exercise selection in the rehabilitation of individuals with rotator cuff tears.

The aim of this clinical trial is to investigate the effects of a dual-task-based exercise program on clinical outcomes in individuals with rotator cuff-related shoulder pain. The study will evaluate the effects of a dual-task exercise approach, in which physical exercises are performed concurrently with cognitive tasks, on pain, functional status, pain catastrophizing and kinesiophobia. These results will be compared with those of a standard shoulder rehabilitation program. The main questions this study aims to answer are: * Is there a difference in pain levels between individuals with rotator cuff-related shoulder pain who participate in a dual-task-based exercise program and those who participate in a standard exercise program? * Is there a difference between these two exercise approaches in terms of shoulder function and psychosocial factors? Participants will: * Participate in either a dual-task-based shoulder exercise program or a standard shoulder exercise program twice per week for 6 weeks. * Undergo clinical assessments at baseline, at week 6, and at week 12.

The primary aim of this study is to determine the clinical effectiveness of patient education alone in individuals with rotator cuff-related shoulder pain and to identify which patient subgroups benefit more from this approach. In addition, the translation and cultural adaptation of the "Patient Knowledge Questionnaire (PKQ-RCRSP)" into Turkish will be carried out to measure the level of patient knowledge regarding patient education.
