Efficacy of a Lower Back Intensive Rehabilitation Program in Occupational Injury Patients and Characteristics of Care: A Retrospective Cohort Study.

ABSTRACT

BACKGROUND The Lower Back Intensive Rehabilitation Program (LBIRP) was developed by hospitals affiliated with the Korea Workers' Compensation and Welfare Service to support patients with lower back pain caused by occupational injuries. We studied the characteristics of patients who participated in this program to assess its efficacy and suggest areas for program quality improvement. MATERIAL AND METHODS This large-scale retrospective cohort study analyzed the electronic medical records and occupational injury insurance data of patients with lower back damage due to occupational injuries who participated in the LBIRP in hospitals affiliated with the Korea Workers Compensation and Welfare Service between April 2017 and 2020. RESULTS Multidimensional analysis showed that pain, isometric strength of the hip, central muscular endurance, neuromuscular control ability, and self-questionnaire scores were significantly different among groups. Further, significant differences were observed in most multidimensional analysis items according to the cause of disease, program period, and severity of disease. There were no significant differences between the groups. CONCLUSIONS Based on the findings of this study, efforts must be continued to improve and standardize the LBIRP. It is expected that future studies with continuous patient follow-up comparing treatment effects among affiliated hospitals will help to expand the LBIRP for rehabilitation in private hospitals.
