Recruitment curves for the femoral nerve cuff electrodes in Subjects 09, 10, 13, 14. Caption: Pulse width-modulated recruitment curves normalized to body weight for four subjects with monopolar spiral nerve cuff electrodes on their femoral nerves. The positive moment values represent knee extension. When the data were collected, Subjects 09 and 10 had been implanted for 4.5 years, and Subjects 13 and 14 had been implanted for 2 years
