Summary

This study aims to compare the effects of post-isometric relaxation (PIR) and post isometric stretching (PIS) techniques on reducing neck pain, improving range of motion, and decreasing neck disability in individuals with neck pain. A randomized controlled trial will be conducted with 50 participants, who will be randomly assigned to one of two groups: one receiving PIR and the other receiving PIS. A single-blind method will be used, meaning the participants will not know which group they belong to. Participants will be selected based on specific criteria related to neck pain and will then be randomly allocated to the PIR or PIS group. Initially, all participants will receive two standard treatments: Transcutaneous Electrical Nerve Stimulation (TENS) and hot pack application. After these treatments, one group will undergo post-isometric relaxation (PIR), which involves 3-5 repetitions of muscle contraction and relaxation, conducted over five consecutive sessions. The other group will receive post-isometric stretching (PIS), which involves stretching after muscle contraction and relaxation, also administered over five consecutive sessions. At the end of the intervention, pain, range of motion, and neck disability will be measured. Pain will be assessed using a standardised pain scale, range of motion will be measured with a goniometer or other appropriate tools, and neck disability will be evaluated using the Neck Disability Index (NDI). Statistical analysis will be performed to compare the effectiveness of PIR and PIS in terms of pain reduction, range of motion improvement, and decreased neck disability.

Conditions

  • Chronic Neck Pain

Interventions

PROCEDURE

Post Isometric Relaxation

All patients were given Trans-Cutaneous Electrical Nerve Stimulation (TENS) in combination with superficial heat for 10 minutes. with a session of 5 days/ week. Group A (PIR) : In this group, participants performed 3-5 rounds of post-isometric relaxation (PIR). Each round involved contracting the target muscle at 30-50% strength for 7-10 seconds, resting for 5 seconds .

PROCEDURE

Post Isometric Stretching

All patients were given Trans-Cutaneous Electrical Nerve Stimulation (TENS) in combination with superficial heat for 10 minutes. with a session of 5 days/ week.Group B (PIS) : In this group participants performed 3-5 rounds of post-isometric relaxation (PIR), which is then followed by a stretch of the same muscle to its new range of motion. Followed by rest of 5 seconds, and then stretching the muscle and holding the stretch for 10-60 seconds
