A test to determine the site of abnormal neuromuscular refractoriness

Abstract

Highlights A recovery cycle (RC) protocol is described with an added supramaximal stimulus (RCSM). Unlike with conventional RC, RCSM refractoriness is unaffected by cooling the muscle. RCSM may help to localize abnormal neuromuscular refractoriness in neuropathies.

The test–retest reliability of large and small fiber nerve excitability testing with threshold tracking

“…One more sensory and motor NET parameter with high variability was refractoriness. Although we paid attention to keeping the temperature between certain limits, this may partly be because of the dependency of this variable to temperature changes ( Tankisi et al, 2022 ). Additionally, rheobase both for sensory and motor NET showed poor reliability.…”
