Fig. 1 The inching test is performed on a control subject and shows (A) the location of the nine recording/stimulation points, (B) the nine recorded sensory action potentials, and (C) a graph of the eight normal conduction delay values (CD/cm) in milliseconds and corresponding orthodromic sensory conduction velocity (OSCV) in meters per second.

Fig. 2 The inching test in a person with mild carpal tunnel syndrome. The classical data are DML, 3.1ms, OSCV, 52m/s. Only the sixth CD/cm is abnormal; this MCD/cm is.74ms and the sixth SAP peak is flattened.
