Distance Measurement for Conduction Velocity Measure from distal edge of wrist to index line of the sensory active electrode. Distal Edge of Wrist Electrode Distal Edge of Wrist Electrode Measure this distance in cm Measure this distance in cm Index Line Index Line * Stimulator (cathode) to proximal detector distance is measured distance plus 3 cm. ©2008 NeuroMetrix.
