Summary

This study aims to compare two treatment methods for piriformis syndrome, a condition that can cause pain in the buttock and leg. Adult patients with piriformis syndrome will take part in the trial. Participants will be randomly assigned to one of two groups. One group will receive focal extracorporeal shock wave therapy (f-ESWT), a non-invasive treatment that uses sound waves. The other group will receive a steroid injection, which is a common treatment used to reduce pain and inflammation. The goal of this study is to find out which treatment is more effective in improving symptoms of piriformis syndrome.

Conditions

• Piriformis Syndrome

Interventions

Type	Name	Description
OTHER	Focal extracorporeal schock wave therapy	Participants in this group will receive a total of 5 sessions of focal extracorporeal shock wave therapy. Each session will deliver 1000 pulses per cm² to the affected piriformis muscle.
