What this trial studies

This research evaluates the effectiveness of focused Extracorporeal Shock Wave Therapy (ESWT) on upper limb spasticity in patients who have suffered a stroke. Participants are randomly assigned to either receive targeted ESWT on their forearm flexor muscles or a placebo treatment that mimics the therapy. The treatment is administered twice weekly over two weeks, with various assessments conducted before, and at multiple intervals after the therapy to measure improvements in muscle function, pain levels, and daily living activities.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have experienced a unilateral stroke and exhibit spasticity in their wrist and finger flexor muscles.

Not a fit: Patients with a history of multiple strokes, other central nervous system disorders, or those who have recently undergone similar therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve upper limb function and quality of life for stroke survivors with spasticity.

How similar studies have performed: Previous studies have shown promise for shock wave therapy in treating spasticity, suggesting potential for success in this approach.
