Abstract

An alternative method for analysis of localized muscle fatigue as performed by Lindström et al. (1977) is presented. The method is based on counting of zero crossing of the electromyographic signal. The method is implemented on a microprocessor computer system. The analysis can be done on line and the result is presented as a plot of the normalized action potential velocity versus time.
