3-axis accelerometer data (first three rows) during piezoelectric stimulation of the extensor digitorum longus (EDL) muscle with 50 ms bursts (ultrasound parameters: 1 MHz, 200 cycle, 200 Hz reputation rate) with our PolyUStimulator. The bottom row shows the piezoelectric stimulation pulses for the implanted stimulator
