Compare the effectiveness of post isometric relaxation technique and postural education VS ultrasound assisted static stretching and postural education on hip extension range of motion, pelvic tilt and quality of life in college students with iliopsoas tightness

This randomized controlled trial will evaluate the effect of Post-Isometric Relaxation (PIR) with Postural Education versus Ultrasound-Assisted Static Stretching with Postural Education on hip mobility, pelvic alignment, and quality of life in physiotherapy students with iliopsoas tightness. A total of 308 participants aged 18–28 years will receive one of the two interventions for six days. Hip extension range, pelvic tilt, and SF-36 scores will be assessed before and after treatment to identify the more effective technique for improving flexibility and posture.
