Figure 1. Mean torque produced by each type of NMES across the group of 11 participants at submaximal stimulation intensities and at the stimulation intensity that resulted in maximal torque (MAX<sub>torque</sub>). *P < .05.

Figure 2. Discomfort scores as assessed using the VAS when mNMES, nNMES, and iNMES were delivered over a range of torque amplitudes. The MAX<sub>torque</sub> corresponds to the stimulation intensity that produced the maximal torque independent of whether it was limited by discomfort or activation of the evertors (n = 11). *P < .05.

Figure 3. Current delivered during mNMES, nNMES, and iNMES over a range of torque amplitudes. The current during iNMES was calculated separately for the iNMES<sub>(m)</sub> and iNMES<sub>(n)</sub> sites. *P < .05.
