Fig. 1

Experimental setup showing the block electrode on the sciatic nerve and proximal nerve stimulation. Force is recorded from the muscle. The waveform is shown below. The upper trace shows the control signal from Labview® with the three amplitude zones and the ramp. The lower trace shows the KHFAC output. The black arrow points to onset when the KHFAC is first turned on. The grey arrow points to where onset occurs for a step change transition from Sub_Block to Post_Sub_Block. This onset can be eliminated by the use of a ramp (T_ramp)
