Effects of exercise therapy on muscular strength in firefighters with back pain

[Purpose] The purpose of this study was to determine how an exercise program focusing on muscular strength could aid firefighters with chronic lower back pain. [Subjects] The research subjects were randomly assigned to two groups, the experimental group (n=8) and the control (n=8). [Methods] The experimental group performed two types of exercise programs four times per week for 8 weeks under supervision. Tests were performed before and after the 8 weeks of exercise in accordance with the Korea Occupational Safety and Health Agency's program. [Results] At the end of the 8 weeks of the rehabilitation program, abdominal muscular strength were significantly increased in the experimental group, and this indicates that the exercise therapy was effective for improvement of muscular strength. [Conclusion] We found that exercise therapy is an effective intervention that can reduce the pain of patients with chronic lower back pain. The firefighters with chronic lower back pain who participated in this study exhibited enhanced lower back muscular strength and obtained some additional benefits. They need regular exercise.
