The IPIs of 2 example MUAPTs, measured during the 25-s constant force region of the contraction. Shown are the IPIs of a (A) stationary MUAPT and (B) moderately nonstationary MUAPT. The Kwiatkowski, Philips, Schmidt, and Shin (KPSS) test statistic, indicated in the upper-right corner of each plot, was used to determine the stationarity of each MUAPT. A KPSS test statistic >0.463 indicated that the MUAPT contained statistically significant nonstationary firing instances.
