Background

Patients with chronic low back pain (CLBP) often struggle with poor posture due to weak core muscles. Dynamic neuromuscular stabilization (DNS) uses techniques based on how infants move to help improve muscle function. While DNS has helped improve posture in other conditions, it’s unclear if it works better for CLBP patients compared to traditional exercises.

Study Objectives

This study aimed to see how DNS training compares to regular core exercises in improving core muscle strength and balance in CLBP patients.

Methods

Sixty CLBP patients were divided into two groups: one received DNS training, and the other did conventional core exercises. Both groups participated in 12 sessions over 4 weeks. They were evaluated before and after the training using ultrasound to measure muscle changes, balance tests to assess posture, and questionnaires to evaluate pain and disability.

Results

After 4 weeks, the DNS group showed significant improvements in muscle strength and balance compared to the control group. Key findings included:

Improved core muscle function (transversus abdominis and diaphragm).
Better balance performance, especially when visual feedback was removed.
Significant reductions in pain and disability scores for both groups, but DNS showed greater muscle improvements.

Conclusions

DNS training is more effective than conventional exercises for enhancing core muscle strength and balance in CLBP patients. This method may help reduce pain and improve overall function.
