Abstract
This study aimed to investigate the effect and durability of eight weeks of dynamic neuromuscular stabilization exercise on pain and basic functional movement in individuals aged 30 to 50 with non-specific chronic low back pain. After targeted recruitment and random grouping, 29 participants (13 in the intervention group and 16 in the control group) completed the trial. The visual analog scale for pain and functional movement screening tests was used to assess patients at pretest, posttest, and 2-month follow-up. The exercise group performed 3 sessions per week of 50–60 minutes of dynamic neuromuscular stabilization exercise for eight weeks, while the control group continued their daily routine activities. Data were analyzed using mixed analysis of variance, independent t-tests, and Bonferroni post hoc tests at a significance level of 0.05. The results showed that the pain index (P ≤ 0.001) and functional movement screening scores (P ≤ 0.001) of the exercise group improved significantly at the posttest. The positive effects of the exercises showed a slight decrease after a two-month period of detraining compared to the posttest, although this reduction was not statistically significant (P > 0.05). The follow-up changes compared to the pretest in the exercise group and the changes between measurement periods in the control group were not significant (P > 0.05). It can be concluded that eight weeks of dynamic neuromuscular stability exercises improved pain and functional movements in individuals with non-specific chronic low back pain, with these improvements persisting for up to two months post-training.
