Comparative Effects of Post-Isometric Relaxation and Reciprocal Inhibition Techniques inPiriformis Syndrome

Starting soon · Not applicable

Conditions studied: Piriformis Syndrome

In brief

Piriformis Syndrome (PS) is a condition which is characterized by pain, numbness, and limited range of motion (ROM) due to compression or irritation of the sciatic nerve by the piriformis muscle. It often leads to discomfort in the buttock region, radiating pain along the posterior thigh, and functional limitations in daily activities. Manual therapy techniques, particularly Muscle Energy Techniques (METs), have been widely used for the management of musculoskeletal dysfunctions, including piriformis syndrome.
