Examining the mean frequency of myoelectric signals produced by dynamic muscle contractions

The mean frequency of the power spectrum of a myoelectric signal is an accepted index for monitoring fatigue in static contractions. There is, however, indication that it may be a useful index even in dynamic contractions. The purpose of this investigation was to examine this possibility. Results obtained while comparing mean frequency data produced from static and dynamic contractions reveal that it may be feasible to use mean frequency as an index for monitoring fatigue in dynamic contractions
