Abstract

Autonomic nerve conduction velocity (ANCV) can be determined non-invasively using peripheral autonomic surface potentials of the skin. The sympathetic skin response (SSR) is a constituent of clinical diagnostics. Several authors have established standardised values for SSR on hands and feet. No systematic investigation of peripheral ANCV has been conducted. The examinations were performed on 30 healthy individuals. The following four points for the placement of leads were located on the upper body: vertebral column in dermatome T6, axilla, hand (palm), 3(rd) finger. The points on the lower body were: vertebral column over dermatome T12, poplitea, foot (sole), hallux(plantar). Stimulation was performed as electrical single square. The ANCVwas calculated as the quotient of the distance and the difference between two SSR latencies. To determine whether the ANCV depends on the temperature, the surface temperature of 10 participants was increased incrementally from 31 to 37 degreesC, measuring the SSR on poplitea, foot and hallux. In the T6 area, the SSR was not detectable in most of the participants. We have therefore not systematically calculated the ANCV in the section T6-axilla. The ANCV in the upper and lower extremities were approximately equal in thearm (1.63 +/-0.45 m/s), thigh (1.74 +/-0.42 m/s) and lower leg (1.56 +/-0.46 m/s). In the distal areas of hand (0.38 +/-0.16 m/s) and foot (0.36 +/-0.14 m/s), the values were significantly lower. Increasing the skin temperature did not significantly change the SSR latency values or, correspondingly, the ANCV. This study indicates that ANCV derived from SSR can be reliablydetermined from healthy subjects.
