Persistent and transient "conduction block" in motor neuron diseases.

abstract：INTRODUCTION:Low-intensity electrical stimuli of digital nerves may generate a double peak potential (DPp), composed of a cathodal (caAP) and an anodal (anAP) potential in orthodromic recordings. METHODS:We studied the effects on caAP and anAP of stimuli of variable intensity, duration, and frequency. We also applied ...
