Fig. 6.

Differences in reference unit firing frequency (ΔF) and baseline reciprocal inhibition (RI). A: ΔF values (pulses/s, pps) did not differ between standing postural sway and seated plantarflexion. B: similarly, baseline RI did not differ between standing and seated postures. Note that a larger negative value denotes increased reciprocal inhibition. Individual values are represented by circles, and the connecting line denotes two values obtained from the same participant. PIC, persistent inward current.
