Abstract

Important information related to the function of active motor units in a contracting muscle is represented within the shapes of the motor unit potentials (MUP), as well as by changes to these shapes between firings arising from shifts produced by delay at the neuromuscular junction (jitter). This work further evaluates a localized timeshifting (with kernel weighted averaging) algorithm presented earlier, verifying that there is a correspondence between increases in the values of timeshifts considered by the algorithm, and increases in observed jitter values.
