Quantitative evaluation of the motor unit potential complexity.
A method for MUAP complexity evaluation is proposed. A complexity coefficient intended for measuring potential complexity is defined, it is a product of filling factor and coefficients measuring the variability of signal parameters. This coefficient has been used to estimate quantitatively the degree of complexity and hence to order a set of potentials. The potential ordering agrees with intuitive expectation. So, it seems that this method may be appropriate for complexity evaluation, and could be applied in the study of remodeling process in neuro- and myopathic diseases.
