The Effect of Eccentric Isokinetic Exercise in Shoulder Tendinopathies

Prof. Dr. Cemil Tascıoglu Education and Research Hospital Organization50 enrolled

Overview

This study aims to evaluate the effects of eccentric isokinetic exercise on pain, shoulder function, and supraspinatus muscle architecture parameters in individuals diagnosed with rotator cuff tendinopathy. The study's primary hypothesis is that controlled eccentric isokinetic loading will induce measurable architectural adaptations in the supraspinatus muscle, in addition to clinical improvement.

Outcomes

Primary Outcomes

To evaluate the effects of an eccentric isokinetic exercise program on shoulder compare outcomes

To evaluate the effects of an eccentric isokinetic exercise program on shoulder pain, function, and ultrasonographic supraspinatus muscle architecture in patients with rotator cuff tendinopathy, and to compare outcomes with a standardized pain was assessed using VAS. The VAS is an ordinal scale that rates pain from 0 to 10. Low scores indicate low pain, while high scores indicate severe pain.

Time frame: 6 mounth

Western Ontario Rotator Cuff Index

It assesses the impact of shoulder pain on five key domains: physical symptoms, sports and recreation, work function, lifestyle, and emotional well-being. The questionnaire takes less than 10 minutes to complete, features 21 items, and is scored out of 2100 points, with higher scores indicating greater dysfunction.

Time frame: 3 months

Ultrasonographic measurement

Supraspinatus muscle thickness was measured in millimeters using ultrasonography. High values indicate good function.

Time frame: 3 months
