A method and apparatus for the assessment of neuromuscular function by estimating motor unit F-wave component time of arrival (TOA), comprising: (i) determining and comparing F-wave component features so as to accurately identify individual F-wave components (ii) repeatedly searching the individual F-wave components and extracting individual F-wavelets from the F-wave components so as to build a complete F-wave TOA profile and (iii) computing and reporting TOA results for the assessment of neuromuscular function.
