Focal Vibration Therapy in Post-stroke Shoulder Pain

Resumen breve

Hemiplegic Shoulder Pain (HSP) is a common and disabling complication after stroke, negatively affecting upper limb function, participation in rehabilitation, and quality of life. Despite the widespread use of conservative and physical therapies, evidence supporting the efficacy of specific non-invasive neuromodulation techniques remains limited. Focal Vibration Therapy (FVT) is a non-invasive physical modality that delivers localized mechanical vibration to targeted muscles or tendons and may modulate pain, muscle tone, and proprioception through frequency-dependent mechanisms. This randomized controlled trial aims to evaluate the efficacy of a multimodal FVT protocol, in addition to standard rehabilitation, compared with a sham intervention plus standard rehabilitation, in reducing pain in patients with chronic post-stroke Hemiplegic Shoulder Pain.
