简要总结
The closed kinetic chain (CKC) of terminal knee extension exercise (TKE) is designed to activate VM activity for knee injury training. This CKC exercise is effective for highest recruiting muscle activity, especially safe for post-operative knee surgery. The study of ACL reconstruction rehabilitation guideline suggests that exercises can be applied within the early phase of rehabilitation to prevent knee laxity and less knee pain compared to open chain exercise. Therefore, it is interesting to investigate the effects of TKE exercise synchronized with metronome pace on change of VM motor unit behavior in post operative ACL reconstruction. This study focuses on the immediate effect of 1-seesion TKE and expects that adding metronome during TKE will enhance neuromuscular control of VM and may change motor unit behavior.
