Sensitivity, low-frequency filter, high-frequency filter, sweep speed, duration of pulse, rate of pulse, and the machine used were not specified.
This study was performed in the supine position, with the elbow and fingers slightly flexed.
According to a previous standardized technique [
1], the author used the antidromic method [
2]. Signals were recorded 14 cm distally from the wrist to a not specified finger (Fig.
1). Probably he recorded sensory potentials from digit II (R), placing the active electrode (A) to the base of the digit and placing the reference (R) 4 cm proximally to the active electrode, slightly distal to the distal interphalangeal joint. Ground (G) electrode position was not specified in the paper; it was probably placed over the midforearm or on the palm of the hand (the figure shows the ground electrode placed on the palm).
