| Outline of Final Research Achievements |
Real time viewing of electromyography (EMG) can be used to see muscular activity (MA) during octave keystrokes (OKS). The aim of this study was to examine how MA during piano OKS was reduced by viewing real time EMG (RTEMG). The subjects were sixteen under and graduate students majoring in piano. The experimental task was to play fortissimo OKS on right side. Surface EMG was used to measure and present the MA of subjects’ upper body muscles. Integrated EMG during the 250 ms of the before keystroke (before and during keystroke: BDKS) and after keystroke (AKS) at the time of peak sound pressure. The biofeedback (BF) task was to consciously reduce the MA by looking at the RTEMG. Significant BF effect was only observed in abductor pollicis brevis. MA of all arm muscles in AKS was significantly lower than that of PDKS. It was assumed that the subjects concentrated on decreasing MA of all arm muscles in AKS for the prevention of injury.
