Low Back Pain (LBP) is one of the most common musculoskeletal disorders and is closely associated with decreased segmental stability of the spine. The multifidus muscle plays an important role in maintaining lumbar stability; however, patients with LBP frequently exhibit reduced activation and neuromuscular control of this muscle. Dynamic Neuromuscular Stabilization (DNS) is an exercise approach based on developmental kinesiology that aims to optimize the coordination and activation of deep stabilizing muscles. This study aimed to determine the effect of Dynamic Neuromuscular Stabilization on multifidus muscle activity in patients with Low Back Pain. The research employed a quasi-experimental design with a pretest–posttest approach. The study subjects were patients with non-specific Low Back Pain who met the inclusion and exclusion criteria. DNS intervention was administered for 4–6 weeks with a frequency of 2–3 sessions per week. Multifidus muscle activity was measured using electromyography (EMG) before and after the intervention. Data were analyzed using a paired t-test or Wilcoxon test according to data distribution. The results demonstrated a significant increase in multifidus muscle activity following DNS intervention (p < 0.05). In conclusion, Dynamic Neuromuscular Stabilization has a positive effect on increasing multifidus muscle activity in patients with Low Back Pain and can therefore be recommended as a physiotherapy intervention to improve lumbar stability and reduce the risk of pain recurrence.
