Summary

This randomized clinical trial aims to compare the effects of post-isometric relaxation (PIR) and post-facilitation stretch (PFS) on pain, range of motion, and disability in individuals with tight hamstring syndrome. Conducted at Riphah Rehabilitation Clinic, Lahore, participants aged 18-35 years with posterior thigh pain will be divided into two groups. Both groups will receive hot pack therapy and core strengthening exercises, with Group A receiving PIR and Group B receiving PFS. Outcomes will be assessed at baseline and after 4 weeks using NPRS, a disability questionnaire, and a goniometer, with data analyzed using SPSS version 25.

Interventions

OTHER

Post Isometric relaxation

Group A will receive Post Isometric Relaxation (PIR) Patient applied the sub-maximal contraction almost 20%. Isometric contraction was held for 10 seconds and then slight stretch for 30 seconds was maintained.4 contractions per treatment with 3 seconds rest between each contraction. This protocol continues 3 days/week for 4 weeks conventional treatment Hot pack for 10 minutes Pelvic bridging: The subjects will be asked to lie supine and with knee flexed and then raise the pelvis upward till the comfort then hold that position for 5 sec and repetitions were 10 times Cat and camel: The subjects will be requested to prone kneel and then take a deep breath from nose while making hump in the back (cat) and breathe out from mouth while curving the spine (camel) for 5 second 10 times repetitions

Post Facilitation stretch

Group B will receive Post Facilitation Stretch (PFS) Isometric contraction was held for 10 seconds and then slight stretch for 30 seconds was maintained. 4 contractions per treatment with 3 seconds rest between each contraction.
