简要总结
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.
详细描述
Neck pain is one of the most prevalent musculoskeletal complaints among young adults, with studies reporting a prevalence of up to 75.7%, making it the fourth leading cause of disability worldwide. Research suggests that weak cervical musculature, reduced muscle-to-bodyweight ratios, and imbalances in muscle strength are key contributors to neck pain and associated disability. Muscle Energy Techniques (METs), particularly Post-Isometric Relaxation (PIR) and Post-Isometric Stretching (PIS), have been widely used to address these issues. PIR involves gentle isometric contractions followed by muscle relaxation and is effective for managing active muscle tone, making it suitable for acute conditions. However, it lacks a stretching component to target passive tone. PIS adds a post-contraction stretch, potentially addressing both active and passive tone, but may cause discomfort in sensitive individuals. While both techniques have shown positive outcomes in reducing pain and improving function, limited research directly compares their effectiveness. Therefore, this study aims to compare PIR and PIS in terms of pain relief, cervical range of motion, and functional improvement in individuals with mechanical neck pain.
According to M.Osama et al in 2020 a study was conducted to compared autogenic inhibition (AI) and reciprocal inhibition (RI) muscle energy techniques (MET) to static stretching (SS) for managing mechanical neck pain. Both AI-MET and RI-MET outperformed SS in enhancing isometric strength, with no adverse effects observed. The findings highlight AI-MET's superiority and support its use in neck pain rehabilitation.
Another study was conducted by Osama M 2024, 78 participants a randomized trial concluded that Muscle and Movement specific PIR is effective in improving neck pain, disability and ROM. Dudonienė V et al preformed a study in 2024 that aimed to investigate the 3 effectiveness of post-isometric relaxation (PIR) compared to self-stretching (SS) in working-age individuals with chronic non-specific neck pain. Result showed PIR group achieved lower pain intensity, greater neck extension ROM and lower neck disability index compared to the SS group.
A study conducted in 2022 investigates the effects of post-isometric relaxation (PIR) versus myofascial release therapy on non-specific neck pain management. Results showed that the PIR group had significant improvements in pain (measured by VAS), disability (NDI), cervical extension, and social QoL compared to the MFR group.
Another study investigated the effectiveness of post isometric relaxation (PIR) combined with traditional physical therapy for treating chronic mechanical neck pain compared to traditional therapy alone. Results showed significant reductions in pain and increases in cervical range of motion (ROM) for group adding PIR to conventional therapy.

Post Isometric Relaxation
Post-Isometric Relaxation (PIR) is used for treating muscle tightness or spasms. It involves a sequence of steps that aim to improve flexibility and reduce muscle tension.

结局指标
主要结局
Pain Intensity
时间窗: 1 week
The Visual Analog Scale (VAS) will be used to measure the intensity of neck pain before and after the intervention. Participants will mark their level of pain on a 100 mm horizontal line, where: 0 mm indicates "no pain", and 100 mm indicates "the worst imaginable pain".
Cervical range of motion
时间窗: 1 week
A universal goniometer will be used to assess cervical spine mobility in the following directions: Flexion Extension Lateral Flexion (Right and Left) Rotation (Right and Left) ROM will be recorded in degrees.
Functional Disability
时间窗: 1 week
The Neck Disability Index (NDI) will be used to assess functional impairment related to neck pain. It is a self-administered questionnaire consisting of 10 sections, including pain intensity, personal care, lifting, reading, headaches, concentration, work, driving, sleeping, and recreation. Each section is scored from 0 to 5, with higher total scores indicating greater disability. The NDI is a validated, open-access tool commonly used in research to measure changes in disability levels pre- and post-intervention.
