Abstract
Values obtained from six procedures for estimating electromyogram (EMG) activity from the unintegrated and average integrated signals were compared to cumulative integration values. Correlation coefficients were derived for repeated measures data used in evaluating single subject performance over time, and for subject means used in comparing group performance. The results indicated that the cumulative integration values are necessary for precise estimates of within subject changes, while all but one of the derived EMG measures were good estimates of group activity.
