Sensitivity was 40 μV/division, sweep speed was 1 ms/division. Low frequency filter, high-frequency filter, duration of pulse, rate of pulse, and the machine used were not specified.
This study was performed in the supine position.
Following the orthodromic method , signals were recorded on the course of the median nerve (Fig. 1) above the wrist (R1), at the elbow (R2), and in the axilla (R3). For recording at the wrist (R1), the active (A) electrode was placed proximally to the distal crease at the wrist; the reference (R) electrode was placed 3 cm proximally to the active electrode. For recording at the elbow (R2), the active (A) electrode was placed proximally to the wrist in the antecubital fossa; the reference (R) electrode was placed proximally to the active electrode. For recording in the axilla (R3), electrodes were placed medially on the course of the median nerve, with the active (A) electrode placed proximally to the elbow and the...
