Effects of Biopsychosocial Interventions on Non-specific Chronic Low Back Pain and Its Related Disabilities among Students

Abstract

Background: This study aimed to investigate the effects of biopsychosocial interventions on non-specific chronic low back pain (NSCLBP) and disabilities caused by it among Students. Study Design: A two-group pretest-posttest randomized clinical trial. Methods: The statistical population of the study was female students enrolled at the first-stage secondary school in Hamadan, Iran. A total of 200 students were selected through cluster sampling and randomized into two groups of intervention and control. The primary evaluation was performed by the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), the Health-Related Quality of Life (SF-36), the International Physical Activity Questionnaire-Short Form (IPAQ-S), the World Health Organization Disability Assessment Schedule (WHODAS), and the visual analogue scale (VAS). Upon developing and implementing the biopsychosocial model-based interventions for ten weekly two-hour sessions, the secondary evaluation was fulfilled, and the extracted data were analyzed using the IBM SPSS version 21. Results: The independent-group t-test results revealed that the mean scores of quality of life (QOL) and physical activity significantly elevated in the intervention group, compared to the control. In addition, the mean value of disabilities, the amount of disorder in the lumbar region, and the VAS scores in the intervention group substantially declined compared to the control group. Conclusion: The significant variations in the biopsychosocial factors demonstrated that the development of some interventions based on the bio-psychosocial model (BPSM) could help manage the NSCLBP and its ensuing disabilities. Therefore, the BPSM-based interventions could be exploited to minimize musculoskeletal disorders (MSDs) in students.
