Note: FES, functional electrical stimulation; Quads, quadriceps; Hams, hamstrings; Gastrocs, gastrocnemius; PW, pulse width, Freq, stimulation frequency; Stim, Average stimulation; L, left; R, right; µs, microseconds; Hz, hertz; µC, micro Coulomb; mA, milliampere; P, participant.
Best session is the session with the highest average power of all sessions per participant. Average stimulation is the average charge delivered per session across all channels, and is an overall measure of the stimulation intensity for the session. Underlined values in bold indicate stimulation amplitudes that were limited due to stimulation-associated pain. Underlined values indicate stimulation amplitudes that were limited due to apprehension with FES. Value in bold and italic indicate a deviation from the default parameter.
