Abstract
Introduction: Chronic non-specific low back pain is one of the prevalent musculoskeletal disorders among nurses, which imposes significant burdens on society. The present research aimed to investigating the effect of motor control approach with and without whole-body vibration (WBV) on pain, static and dynamic balance of the female nurses with chronic non-specific low back pain (NLBP).
Materials and Methods: The statistical sample consisted of 75 female nurses with chronic NLBP and with a history of pain for more than three months. They were randomly divided into three groups: the combined group (motor control with whole-body vibration), the motor control group and the control group. The pain intensity was measured using a visual analog scale, and static and dynamic balance were measured using the Biodex balance meter. Tests were conducted before and after eight weeks. The Shapiro-Wilk test was used to check if the data were normally distributed; the parametric analysis of variance (ANOVA) and non-parametric Kruskal-Wallis tests were used if the data followed a normal distribution or did not, respectively.
Results: The research results showed a significant difference (P < 0.001) in pain intensity, and static and dynamic balance between the combined and motor control groups and the control group; however, no significant difference (P > 0.05) was observed between the combined and motor control groups.
Conclusion: It seems that exercise improves the symptoms of chronic NLBP in female nurses, and both exercise approaches were equally effective.
