Physical Therapy Techniques

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.

The goal of this study \[type of study: clinical trial\] is to was planned to investigate the effect of motor imagery training given to geriatric individuals with action observation on their balance performance and to compare these two methods. The main questions it aims to answer are: 1. Is virtual reality-based balance training given together with action observation and motor imagery for six weeks in geriatric individuals more effective in improving static balance than virtual reality-based balance training given alone? 2. Is virtual reality-based balance training given together with action observation and motor imagery for six weeks in geriatric individuals more effective in improving dynamic balance than virtual reality-based balance training given alone? 3. Is virtual reality-based balance training given together with motor imagery for six weeks in geriatric individuals more effective in increasing balance confidence than virtual reality-based balance training given alone? 46 geriatric individuals will be randomized into 2 groups. Along with action observation, motor imagery training and virtual reality-based balance training will be given to the study group. On the other hand, only virtual reality-based balance training will be given to the control group. All assessments will be repeated before and after the trainings. The trainings will be applied 2 days a week for 6 weeks. Each training session; 25 minutes for the control group and 45 minutes for the study group.
