Figure 2: Pre and postoperative nerve conduction study of the median nerve. The sensory nerve action potential (SNAP) was antidromically recorded over the index finger with stimulation at wrist 14 cm away from the active electrode, and the compound motor action potential (CMAP) was recorded over thenar muscles with stimulation at the wrist 8 cm away from the active electrode. Note that the SNAP reappeared and the CMAP of the right median nerve underwent a significant recovery in distal motor latency on the postoperative study at 1 year
