Summary of femoral motor and saphenous sensory nerve conduction studies. Time axis is the same for all plots with preoperative period shaded. Measurements in this region are used as baseline values. Dashed lines indicate C-FINE-elicited CMAPs. Solid lines indicate surface-elicited CMAPs (the clinical standard). CMAP is measured at RF. a Femoral MNCV. Mean MNCV of quadriceps muscles compared to clinical minimum normal velocities. Error bars represent SEM between velocities to the heads of quadriceps muscles. b Femoral CMAP Amplitudes: C-FINE-elicited compared to baselines surface-elicited 2 weeks preoperatively and minimum normal values. C-FINE-Elicited CMAPs also compared with subject sitting (hips flexed 90°) and supine. Error bars represent standard deviations between 3 trials of supramaximal stimulation. c Femoral CMAP Areas collected and presented identically to CMAP amplitudes and at the same time points. d Saphenous SNAP Amplitudes. Postoperative amplitudes compared to baseline elicited 2 weeks preoperatively and minimum normal amplitudes
