Relative and absolute refractory periods were determined in sensory fibres of 24 median nerves and in 19 sural nerves of 30 volunteers aged 20–60 years, who had no sign of a neuromuscular disorder. Th

The findings support the assumption that peripheral nerve myelinated fibers are usually involved in MS.

Refractory period studies in a human neuromuscular preparation.

The absolutely refractory periods of the distal motor nerve branches and of the muscle fibres were found to be similar, the majority being within the 2.5--3.0 ms range; the values were distributed in a unimodal manner.

Effects of age, temperature, and disease on the refractoriness of human nerve and muscle.

No significant changes in muscle fibre excitability could be demonstrated in either condition or in patients with renal failure or motor neuropathies.

The relationship between the axonal conduction velocity and refractory period observed in healthy subjects did not hold for patients with neuropathies and neuromuscular disorders, and the significance of these findings with regard to the clinical application of the Hopf technique for determining the conduction Velocity spectrum of peripheral motor nerves is discussed.

The reliability of the commonly used blocking technique for measuring the conduction velocity spectrum of the peripheral motor nerve in man, as first described by Hopf in 1962, was tested and an inverse relationship between the axonal conduction Velocity and the refractory period was observed.

The refractory periods and the recovery curves of the ascending and descending conductive spinal cord evoked potentials (SCEP) in cats are estimated to be the result of elimination of the synaptic inhibitory influence by the conditioning stimulus of the paired stimuli for the descending SCEP.

Refractory period of human motor nerve fibres.

Whereas recovery in amplitude of the test response was unrelated to the length of the refractory segment, change in latency was greater with the longer refractORY segment, although not in proportion to the distance.
