Probabilistic model of the spatial distribution of muscle fibres in human muscles. (English) Zbl 0578.92011

Summary: An analytical model and computer simulation model for measuring fibre density in motor units of human skeletal muscles have been described. The model was developed for Gaussian distribution of the fibres in the motor unit territory.
It has been shown that fibre density measurement using a triggering fibre was a biased estimate of the actual density of the fibres in the territory. The effects of varying the standard deviation of the spatial distribution on the estimate of fibre density has been investigated, and it has been shown that for high values of standard deviation a uniform distribution of the fibres in the territory was a good first order approximation.
