Method and device for evaluating nerve impulse propagation velocity and latency of electrodermal reflexes

摘要

The method and reactometric device provide for separate or simultaneous evaluation of latency and electrodermal reflex propagation speed through postganglionic sympathetic nerve fibers. Evaluation is carried out by help of electronic interval counting devices and yields certain correlations enabling differentiation between the central and peripheral neurovegetative fatigue as well as intoxication phenomena of peripheral vegetative fibers. Evaluations are conducted through two electrodes located on the same innervation area, i.e. on the longitudinal axis of palm, the electrodes being spaced by a known distance which is considered in the evaluation of electrodermal reflex propagation. The first electrode intercepts the electrodermal reflex used in the evaluation of latency.
