Introduction: Work-related musculoskeletal disorders (WRMSD) are considered the main cause of occupational diseases. Health care workers, nursing assistants, and service forces that perform manual labor are the most vulnerable to musculoskeletal disorders, especially low back pain, due to the nature of their jobs. The purpose of this study was to compare the effectiveness of corrective exercise training to ergonomic principles training on low back pain in nursing assistants and service forces. Methods: A nonrandomized clinical trial study was done on 75 staff (nursing assistants and service forces) with low back pain. The participants were divided into three groups: corrective exercise training, ergonomic principles training, and control group. Pain intensity and disability questionnaires were completed before and after 8 weeks of intervention by each group and analyzed. Results: The mean intensity of pain after intervention in corrective exercises group (3.8 ± 1.5) was markedly less than the ergonomic group (4.7 ± 1.4) and control group (5.5 ± 1.7) (P = 0.001). The mean disability score after intervention in the corrective exercises group (17.3 ± 9.6) was significantly less than the ergonomic group (21.8 ± 12.6) and control group (25.3 ± 11.2) (P < 0.001). Conclusion: While corrective exercises training and ergonomic principles training both have a significant effect on reducing the severity of pain and disability caused by low back pain, corrective exercises training is more effective than ergonomic principle training.
