Objective: This study evaluated the effectiveness of a primary prevention program—including a field survey, environmental adjustments, and a lower back pain prevention class conducted by physiotherapists—on reducing lower back pain and improving work performance among Japan Air Self-Defense Force personnel over an eight-month period.
Methods: Seventy-seven personnel (71 males, 6 females; mean age 33.4±10.0 years old) participated. Workplace ergonomics were assessed through a preliminary field survey, and feedback was provided to reduce lumbar strain. Participants attended a prevention class that included education on low back pain and guided exercises. Questionnaires were administered before and eight months after the intervention, covering working hours, sleep, work performance (percentage), the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ), and symptoms of low back pain and fatigue. Statistical analyses were performed using the Mann–Whitney U-test with significance set at p<0.05.
Results: Significant reductions in low back pain and fatigue were observed at follow-up, along with a significant improvement in work performance. However, environmental adjustments were not implemented.
Conclusion: A structured prevention program led by physiotherapists can reduce low back pain and enhance work performance among Air Self-Defense Force personnel, highlighting the value of educational and exercise-based interventions.
