Comparative Effectiveness of Active Isolated Stretching, Muscle Energy Technique and Myofascial Release in Non Specific Neck Pain

Non specific neck pain is a common musculoskeletal condition affecting functional ability and quality of life. Various physiotherapy interventions such as active isolated stretching (AIS), muscle energy technique (MET) and myofascial release are used in clinical practice, but their comparative effectiveness remains unclear. Objective: To compare the effectiveness of AIS, MET and MFR in reducing pain and improving cervical range of motion in individuals with non - specific neck pain. Methods: A total of 130 participants aged 18 - 30 years with non specific neck pain were recruited and randomly divided into three groups: MET (group A), MFR (group B) and AIS (group C). Interventions were administered three times per week. Pain intensity was measured using the numerical pain rating scale (NPRS) and cervical range of motion was assessed using a goniometer. Data were analysed using ANOVA and post hoc test. Results: All three groups showed significant improvement in pain and cervical range of motion following intervention. However, intergroup comparison revealed no statistically significant difference in pain reduction (p > 0.05). Significant differences were observed in certain range of motion parameters such as lateral flexion and rotation (p < 0.05). Conclusion: AIS, MET and MFR are equally effective in managing non- specific neck pain. These interventions can be used interchangeably in clinical practice based on patient needs and therapist preferences.
