Chapter

Original Settings

Sensitivity was 20 µV/division, low frequency filter was 20 Hz, high-frequency filter was 2 kHz, sweep speed was 0.2, 0.5 and 1 ms/division, and the machine used was a specially designed designed amplifier with short blocking time (1 ms) and a low noise (0.5 µV RMS at bandwidth of 2 KHz). Duration and rate of pulse were not specified.

Position

This study was performed in the supine position.

Recording

Following the antidromic method [ 1], signals were recorded from digit II (index finger) using ring electrodes (Fig. 1). The active electrode (A) was placed around the proximal interphalangeal joint of digit II; the reference (R) was placed on the distal interphalangeal joint of the same finger. Ground (G) electrode was placed around the forearm (author used a Velcro strap).
