Outline of Final Research Achievements

Using X-ray imaging, musculoskeletal model analysis, and electromyography, we examined the safety and effectiveness of the front bridge exercise performed by extending the knee in the prone position with the fulcrum placed at the proximal front leg. Findings confirmed the restraint of the tibial front displacement and adequate muscle activity. It was therefore revealed that the front bridge was safe and useful training for patients after anterior cruciate ligament reconstruction. It was confirmed by the same method that in the front bridge with the distal leg fulcrum, the contraction force of the quadriceps femoris muscle and gravity drew the tibia forward. Therefore, the safety and effectiveness were shown for the posterior cruciate ligament-deficient knee. Furthermore, the muscle activity of the front bridge was higher than that of straight leg raising and muscle setting. Therefore, the front bridge exercise was effective knee extensor muscle training for knee osteoarthritis.
