Abstract
The purpose of this study was to investigate muscle recruitment patterns for a task routinely performed in industry, under conditions which might be encountered in industry rather than in a controlled laboratory setting. Subjects encountered two asymmetric loading conditions (minimal and substantial) and two trunk motion speed conditions (normal and fast) and performed several repetitions of each condition. Electromyographic (EMG) voltage data pertaining to four pairs of trunk muscles were collected for analysis. The timing of certain events in each signal (start, peak, and end times of elevated activity) were determined. From these events, networks were constructed which portrayed average muscle recruitment order results which were found to occur under all loading and velocity conditions encountered by the subjects. Only two event-pairs were found to occur consistently for all subjects. Event-pairs which were related to changes in resistance or velocity were found for each subject. Some subjects shared event-pairs, but only one pair was found to occur for all subjects.
