Abstract :
Weakness of the lumbar flexor and extensor muscles is among the most important contributors to low‑back pain. Considering the role of dynamic neuromuscular stability (DNS) training on muscular strength, the present study was conducted to determine the effect of DNS training on lumbar flexor and extensor strength in women with chronic low‑back pain. Twenty middle‑aged women with at least six months of chronic low‑back pain were recruited as participants and randomly assigned to a DNS‑training group or a control group. DNS training was performed three times per week for eight weeks. Lumbar flexor and extensor strength was measured with a digital dynamometer before and after the intervention. Results indicated that DNS training produced a significant increase in flexor strength (P = 0.001) and extensor strength (P = 0.001), whereas the control group showed no significant changes for flexors (P = 0.141) or extensors (P = 0.104). The findings suggest that DNS training can enhance lumbar flexor and extensor strength in women with chronic low‑back pain. Because weakness of these muscles is a major factor in the development of chronic low‑back pain, the program can be considered a suitable strategy for reducing related impairments. Nevertheless, further studies are needed to confirm these results.
