A method for the assessment of neuromuscular function by the detection and classification of late wave activity, comprising: (i) pre-processing an ensemble of traces so as to attenuate noise, PFI and baseline disturbances; (ii) identifying time segments of late wave activity in the ensemble of traces; (iii) classifying the time segments of late wave activity into F-wave, A-wave and Repeater segments by exploiting the variable morphology of F-waves across the traces and the fixed morphology of A-waves and Repeater waves across the traces; and (iv) searching the traces in the vicinity of the F-wave trace segments on a trace-by-trace basis so as to identify the F-wave onset latency.

Detection and classification of neuromuscular late wave activity for the assessment of neuromuscular function

This invention relates to the detection of bioelectric signals indicative of neuromuscular function. A mapping biosensor array is first used to identify, relative to reliable anatomical landmarks, the optimal myoelectrical detection site for the majority of the population. Then a diagnostic biosensor array is fabricated using this information so that when the diagnostic biosensor array is positioned on an individual using the reliable anatomical landmarks, the detection electrode is automatically positioned over the optimal detection site.
