Dynamic Neuromuscular Stabilization Exercise and Chronic Lumbar Disc Herniation: Effects on Pain, Mobility, and Trunk...

Area of Science:

• Physical Therapy
• Rehabilitation Medicine
• Exercise Science

Background:

• Chronic lumbar disc herniation affects numerous women, leading to pain and functional limitations.
• Current rehabilitation strategies may not fully address the underlying neuromuscular deficits.
• Dynamic Neuromuscular Stabilization (DNS) is a therapeutic approach focusing on developmental movement patterns to improve core stability.

Purpose of the Study:

• To evaluate the efficacy of an 8-week Dynamic Neuromuscular Stabilization (DNS) exercise program.
• To assess the impact of DNS on pain intensity, lumbar range of motion, functional disability, and trunk muscle endurance.
• To compare the outcomes of DNS training with routine physical activity in women with chronic lumbar disc herniation.

Main Methods:

• A randomized controlled trial involving 30 women (aged 30-40) with chronic lumbar disc herniation.
• Participants were assigned to either an experimental group (DNS exercises) or a control group (routine activity).
• Outcome measures included Visual Analog Scale (VAS) for pain, modified Schober test for lumbar mobility, Oswestry Disability Index (ODI) for function, and McGill endurance test for trunk muscle endurance.

Main Results:

• The DNS group showed significant improvements in pain reduction, lumbar mobility, functional capacity, and trunk muscle endurance (p < 0.05).
• The control group exhibited no significant changes in the measured variables (p > 0.05).
• Post-intervention analysis revealed significant between-group differences favoring the DNS group across all outcome measures (p < 0.007).

Conclusions:

• An 8-week DNS program is an effective intervention for managing chronic lumbar disc herniation in women.
• DNS exercises significantly alleviate pain, enhance lumbar mobility, reduce disability, and improve trunk muscle endurance.
• DNS presents a viable and effective rehabilitation strategy for individuals suffering from chronic lumbar disc herniation.
