Abstract
This study assessed electrically-evoked sustained muscle contractions with real-time changes in near-infrared spectroscopy and mechanomyography signals. Twenty healthy volunteers performed electrical-evoked wrist extension for 10 min. Root mean square derived from MMG (%RMS-MMG) and tissue oxygen saturation (%StO 2 ) from NIRS of the extensor carpi radialis (ECR) muscle were monitored throughout the sessions. The correlated responses of these two measures comprised of 7 consecutive sets of 10 contractions each. %StO 2 revealed an initial decline from muscle contraction 1 to 10 and then an increase from contraction 11 to 70. For %RMS-MMG, a significant decrease was observed from contraction 1 to 10 as well as from contraction 41 to 60 while an increase was seen from contraction 11 to 40 and from contraction 61 to 70. Positive low-order correlations were found between %StO 2 and %RMS-MMG during the start of the exercise while later on, the two variables were negatively correlated. As the number of contractions increased over time, increased %StO 2 revealed good oxygen saturation aligned with decreased %RMS-MMG values, suggesting decreased muscle fiber activation and strength. In this study, the physiological muscle responses were associated with its mechanical characteristics.
