Near-fiber electromyography

Describe and evaluate the concepts of near fiber electromyography (NFEMG), features used, including motor unit potential (NFMUP) duration dispersion, which relate to distal axonal branch muscle conduction time NFMUP segment jitter, a new measure temporal variability neuromuscular junction transmission (NMJ), fibre for fibres (i.e. NF jitter), methods obtaining their values. Trains high-pass filtered potentials (MUPs) trains) were extracted from needle-detected EMG signals assess changes in (MU) morphology electrophysiology caused by disorders or ageing. Evaluations using simulated data completed example human are presented. NFEMG feature values can be used detect sprouting, slowing NMJ delay as well MU diameter variability, jitter. These detected prior alterations size numbers. The evaluations clearly demonstrate support that dispersion reflect branching, and/or jiggle jitter early has augment clinical diagnosis tracking disorders.
