What this Trial Is About
Researchers are evaluating the effects of kettlebell training on shoulder pain, function, and performance in individuals with Rotator Cuff-Related Shoulder Pain. The study aims to compare the improvements from kettlebell exercises with those from a standard rehabilitation program over an 8-week period. This randomized controlled trial is designed to provide higher quality evidence on kettlebell training's therapeutic impact on shoulder conditions. Participants will be randomly assigned to one of two groups: an 8-week kettlebell exercise group or an 8-week standard rehabilitation program group. Each group will follow their respective exercise regimen to assess differences in pain perception, shoulder function, and performance. The study includes a quadruple masking design to reduce bias in the evaluation of these therapies. During the study, participants will undergo assessments before and after the 8-week program. These assessments include the Shoulder Pain and Disability Index, several functional performance tests like the Seated Single-Arm Shot-Put Test and Upper Extremity Y Balance Test, muscle strength evaluations, and hand grip strength measurements. Researchers will also use the Global Rating of Change to monitor overall improvement. The total participation duration covers these evaluations and the exercise interventions.
