Abstract
The vastus medialis oblique (VMO) and vastus lateralis (VL) muscles at the knee joint play important roles for coordination, stability, and posture control. However, no currently available device records muscle activity while simultaneously warning users regarding abnormal muscle activity. This study used a commercialized electromyography sensors placed on the VL and VMO to monitor muscle activity while triggering warnings and vibration feedback to the muscles when an undesired ratio of VL/VMO muscular activation level set by current study was detected. The system was able to trigger alarms when the subject performed moderate-intensity activity and avoid triggering during low-intensity activity. Further research is needed of high-intensity exercises, such as running or weightlifting, to determine the effects of increased muscle activity on the judgment of the undesired ratio of VL/VMO muscular activation level using the device reported in the current study.
