Purpose: Functional disability, impaired balance, and trunk muscle endurance are among the major changes in patients with Non-specific Chronic Low Back Pain (NCLBP). Investigating the relationship between these factors and Functional Movement Screen (FMS) can facilitate effective pain management and functional problems in these patients. This study aimed to assess the relationships between FMS and pain, dynamic balance, and trunk muscle endurance in military personnel with NCLBP. Methods: The present study was of a correlational research design. The study subjects were 50 male military personnel with NCLBP (Mean±SD age=33.30±3.94 y, height= 175.32±5.50 cm, & weight=74.05±3.64 kg). FMS was evaluated by FMS tests and pain severity was assessed through Quebec Back Pain Disability Scale; the dynamic balance was evaluated by Y-Balance Test (YBT), and the trunk muscle endurance was measured by the ITO test. Statistical analysis was performed by SPSS. Pearson correlation coefficient at a significance level of P<0.05 was used to examine the association between the research variables. Results: Pain (P=0.04, r=-0.285) was negatively correlated with the FMS. The FMS was positively associated with the dynamic balance (P=0.014, r=0.346) and trunk muscle endurance (P=0.02, r=0.381). Conclusion: The FMS can be recommended as a functional assessment tools to identify functional deficits in military personnel with NCLBP. The data suggested that the researchers could employ the FMS as a useful tool in designing more effective treatment plans and improving the functional capacity of individuals with CLBP.

Background Pre-participation examinations are the standard approach for assessing poor movement quality that would increase musculoskeletal injury risk. On the other hand, the neuromuscular control plays a significant role in the prevention of injury and rehabilitation. The main purpose of this study was to determine the effect of an 8-week neuromuscular training on functional movement screen (FMS) in injury-prone military athletes. Methods In the present quasi-experimental study, forty injury-prone male military athlete were identified by functional movement Screen. Functional Movement screen were assessed before and after the 8-week program. Participants were placed into 1 of the 2 groups: intervention (n = 20) and control (n = 20). The intervention group was required to complete a neuromuscular training program that met 3 times per week for 8-week. Data analysis was done using the independent t-test and analysis of covariance at the significant level of p < 0.05. Results The comparison of total FMS score indicated a significant difference (P < 0.05 and effect size = 0.83) between intervention (17.75 ± 1.55) and control (11 ± 1.55) groups. A significant improvement in mobility (p < 0.05 and effect size = 0.39), stability (p < 0.05 and effect size = 0.77) and advanced movement (p < 0.05 and effect size = 0.75) were also found. Conclusion An 8-week neuromuscular training program enhances functional movement screen in military athletes. It seems that this training program can minimize injury risk in injury-prone individuals.
