The effect of dynamic neuromuscular stability (DNS) training on dynamic balance and functional disability in athletes with non-specific chronic low back pain

The aim of this study was to investigate the effect of dynamic neuromuscular stability (DNS) training on dynamic balance and functional disability in athletes with non-specific chronic low back pain.

The present study is quasi-experimental, applied with pre-test and post-test design. The sample consisted of 24 male team athletes with chronic non-specific low back pain in two equal and random control groups and experimental were divided into. The control group did not participate in any treatment and rehabilitation activities during this period and was engaged in normal daily activities. The experimental group performed dynamic neuromuscular stability training for 8 weeks. Also, before and after the intervention, the Oswestry questionnaire was used to evaluate the functional disability and the Y balance test was used to evaluate the dynamic balance. The data were analyzed using analysis of covariance (ANCOVA) at the significant level of p < 0.05.

The results of intergroup comparison after dynamic neuromuscular stability training showed a significant difference in improving dynamic balance and functional disability in the experimental group compared to the control group (P <0.05).

Based on the findings of this research, dynamic neuromuscular stability exercises improve functional disability and dynamic balance in athletes with non-specific chronic low back pain.
