Brief Summary

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 home exercise program.

Conditions

Rotator Cuff Tendinopathy; Rehabilitation Exercise

Keywords

rotator cuff tendinopathy; eccentric exercise; muscle architecture; ultrasonography

Outcome Measures

Primary Outcomes (3)

• 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.

  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.

  3 months

• Ultrasonographic measurement

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