Fig. 3From: Reduction of the onset response in kilohertz frequency alternating current nerve block with amplitude ramps from non-zero amplitudesComparison of minimum ramp times required for elimination of second onset: Each top trace is the force, and the bottom trace is the amplitude control waveform. Black arrows show onset at the start of KHFAC. The gray bar shows proximal stimulation which was run until ~ 23–25 s. Different Sub_Block values were evaluated and the smallest ramp time to produce no onset is displayed in this graph. Higher Sub_Block values require shorter ramp times to eliminate secondary onsetBack to article page
