Efficacy of Mckenzie and Isometric Strengthening Exercises to Improve ROM in Patients with Non-Specific Neck Pain-A Systematic Review

Background: Non-specific neck pain is a prevalent musculoskeletal disorder that often results in reduced cervical range of motion (ROM) and impaired quality of life. McKenzie exercises and isometric strengthening exercises are two widely adopted physiotherapeutic approaches. Objective: To systematically review the existing literature and evaluate the efficacy of McKenzie and isometric strengthening exercises in improving ROM among patients with non-specific neck pain. Methods: This randomized controlled trial aimed to compare the efficacy of McKenzie exercises, isometric strengthening, their combination, and standard care in improving cervical range of motion (ROM), reducing pain, and minimizing disability in individuals with NSNP. 40 participants with 20-50 years were randomly assigned to four groups. Assessments using a goniometer (ROM), Visual Analogue Scale (VAS), and Neck Disability Index (NDI) were recorded at baseline and after four weeks. Results: Most studies reported significant improvement in cervical ROM post-intervention. Combining McKenzie and isometric exercises yielded better results than either intervention alone in several studies. Conclusion: The combination of McKenzie and isometric strengthening exercises appears to be effective in improving ROM in patients with non-specific neck pain. Further high-quality RCTs are needed to confirm these findings.
