Objective: Non-specific chronic low back pain is one of the most common musculoskeletal disorders, which can affect motor function, balance, and mental health. The aim of this study was to investigate the effect of Dynamic Neuromuscular Stabilization (DNS) exercises on pain intensity, functional disability, motor balance, and psychological components including anxiety, depression, and fear of movement in women with non-specific chronic low back pain.

Methods: This randomized clinical trial included women with non-specific chronic low back pain who were randomly assigned to experimental and control groups. The control group received conventional physiotherapy, while the experimental group performed supervised DNS exercises in addition to physiotherapy for six weeks. Assessments at pre- and post-intervention included pain intensity (VAS), functional disability (Oswestry Disability Questionnaire), dynamic balance, motor performance, and psychological measures of anxiety, depression, and fear of movement. Data were analyzed using analysis of covariance (ANCOVA) controlling for pre-test scores.

Results: The results showed that performing DNS exercises was associated with improvements in pain intensity and reduction of functional disability. In addition, dynamic motor balance and motor performance were significantly improved in participants who performed DNS exercises. In the psychological domain, a significant reduction in stress and depression was observed, whereas changes in anxiety and fear of movement were not significant.

Conclusion: The findings indicate that DNS exercises can be an effective non-pharmacological intervention alongside conventional physiotherapy, leading to improvements in balance, motor performance, and certain psychological components in women with non-specific chronic low back pain. The use of these exercises is recommended in rehabilitation programs for these patients.
