PURPOSE: The purpose of this study was to examine effects of an exercise treatment program on lumbar extensor muscle strength and pain of rehabilitation patients following lumbar disc herniation surgery. SUBJECTS: This study randomly allocated 14 rehabilitation patients after lumbar disc herniation surgery to an exercise therapy group (ETG, n = 7) and a control group (CONG, n = 7). METHODS: Lumbar extensor muscle strength was measured using a Medx lumbar extension machine (Medx, USA) and pain was assessed using a visual analog scale (VAS). RESULTS: ETG showed significant improvements in all items that measured lumbar extensor muscle strength and pain after the intervention, but CONG did not exhibit any significant improvements. CONCLUSION: The exercise treatment program for rehabilitation patients after lumbar disc herniation surgery was effective at strengthening lumbar extensor muscles and reducing pain.
