Is this trial a fit for you?

Likely a good fit

Ideal candidates are active amateurs or professionals with at least 3 years of sports participation, Tegner Activity Scale ≥5, shoulder pain for at least 6 weeks with pain ≥3/10 and symptoms worsening with resisted flexion, abduction, or external rotation, and diagnoses such as rotator cuff tendinopathy or small tears (<1 cm).

Probably not a fit

Patients with prior shoulder fracture or surgery, adhesive capsulitis, significant passive range-of-motion loss, major multidirectional instability, or neurological signs are excluded and unlikely to benefit from this protocol.

What this trial studies

This interventional trial enrolls people with rotator cuff–related shoulder pain and assigns them to 8 weeks of kettlebell exercises or a standard exercise rehabilitation program. Pain, shoulder-specific function measures, and performance tests are collected before and after the intervention to compare effects between groups. Eligible participants are typically active athletes with at least 3 years of sports participation and a Tegner Activity Scale score of 5 or higher, and may include those with rotator cuff tendinopathy or small tears (<1 cm). The study excludes individuals with prior shoulder fracture or surgery, adhesive capsulitis, major instability, limited passive range of motion, or neurologic signs.

Why it matters

Potential benefit: If successful, kettlebell training could provide an effective, exercise-based option to reduce pain and improve shoulder function for active people with rotator cuff–related shoulder problems.

How similar studies have gone: High-quality evidence specifically on kettlebell training for rotator cuff pain is limited, though exercise-based rehabilitation approaches for rotator cuff conditions have shown modest benefits in prior studies.
