Effects of McKenzie Therapy on Cervical Proprioception and Postural Control in Patients with Chronic Non-Specific Neck Pain: A Randomized Controlled Trial

Abstract

Background: Chronic non-specific neck pain is a common musculoskeletal disorder that affects proprioception and postural control, leading to functional limitations and an increased risk of falls. McKenzie therapy, a widely used intervention focusing on self-management and mechanical diagnosis, has been proposed as an effective treatment, and its impact on cervical proprioception and postural control remains underexplored. Objective: To evaluate the effects of McKenzie therapy on cervical proprioception and postural control in patients with chronic non-specific neck pain. Methodology: A randomized controlled trial was conducted at Irfan General Hospital with 26 participants diagnosed with chronic non-specific neck pain. The participants were randomly assigned to two groups: the McKenzie therapy group (n=13) and the conventional physiotherapy group (n=13). Interventions were conducted for 8 weeks. Outcome measures included cervical joint position sense (measured through laser pointer repositioning tests), postural control (assessed using a balance platform), and pain/disability scores (using the Neck Disability Index and Visual Analog Scale). Independent Sample T-tests were used for normally distributed data, while the Mann-Whitney U test was used for non-normally distributed data.  Data were analyzed using mixed ANOVA to assess group differences over time. Results: The McKenzie therapy group showed statistically significant improvements in cervical joint position sense and postural control compared to the conventional therapy group (p<0.05). Additionally, pain and disability scores were significantly lower in the McKenzie therapy group, indicating superior functional recovery. Conclusion: McKenzie therapy is an effective intervention for improving cervical proprioception and postural control in patients with CNSNP. These findings support its integration into rehabilitation protocols for individuals with chronic neck pain to enhance sensorimotor function and overall quality of life.
