Simulation of macro EMG motor unit potentials

摘要: Abstract Macro EMG motor unit potentials (MUPs) have been simulated. The effects on MUP parameters of number fibres, fibre diameter, end-plate scatter, nerve branch delay, territory and electrode position studied. shape is sensitive to in the vicinity end-plates. It mainly reflecting scatter delays. Away from end-plates wave principally determined by diameter distribution. Total muscle fibres their mean act as gain factors at all recording positions. In simulations area signal appears be a better measure strength than amplitude. offers much less selective conventional single therefore new aspects can quantified. Preliminary results neuromuscular disorders are consistent with actual findings.
