The Effect of 8 Weeks of Dynamic Neuromuscular Stabilization Training on Pain, Electromyography Activity of Lumbar Muscles, and Quality of Life in People with Chronic Low Back Pain

Abstract

Objectives: To evaluate the effects of an 8-week DNS training program on pain, EMG activity, and quality of life in individuals with CLBP. Design: Semi-experimental study. Participants: Thirty male participants with non-specific CLBP, divided into DNS (n=15) and control (n=15) groups. Main Outcome Measures: Pain levels (Quebec Back Pain Disability Scale), lumbar muscle EMG activity (MegaWin EMG device), and quality of life (SF-36 questionnaire). Results: The DNS group showed significant pain reduction (P=0.00), increased EMG activity in rectus abdominis (P=0.000), erector spinae (P=0.002), and gluteus maximus (P=0.002), and improved quality of life (P=0.02). Conclusions: DNS exercises significantly reduce pain, enhance muscle activity, and improve quality of life in CLBP patients
