Abstract: 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.

Abstract: 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.

Abstract: A disposable, multi-purpose cardiovascular autonomic neuropathy testing device which comprises a tubular body having a distal end, a proximal end and a passageway extending therebetween; at least one ECG electrode disposed on the exterior surface of the tubular body for monitoring ECG signals of a patient holding the tubular body; a breathing sensor attached to the tubular body for monitoring breathing through the passageway; a closure mechanism attached to the tubular body for selectively restricting the passageway; and a pressure monitor attached to the tubular body for confirming when a pre-determined pressure has been established in the passageway; whereby the testing device can be used to conduct (i) metronomic breathing tests, (ii) Valsalva maneuver tests, and (iii) HRV standing tests.
Abstract: A method for the assessment of neuromuscular function by motor unit number estimation, comprising: (i) determining and controlling stimulation and data acquisition process via pre-configured electrode array so as to acquire stable and less uncertainty MU responses; (ii) pre-processing acquired MUs responses so as to attenuate noise, determine MUs activity region, and improve processing speed and accuracy; (iii) minimizing alternation effects by globally searching and comparing SMUPs; (iv) eliminating alternation effects by identifying alternating MUs directly; and (v) computing and reporting MUNE results, as well as the statistical description of these MUN estimates to evaluate its robustness.
Abstract: In one form of the present invention, there is provided a method for detecting an A-wave, the method comprising: applying a series of stimuli to a nerve; recording a series of late responses; creation of a feature space map from an ensemble of late responses; identification of clusters within the feature space that represent A-wave components; consolidation of A-wave components into a discrete collection of A-waves; removal of false positive A-waves; and extraction of A-wave characteristics.
Abstract: An apparatus and method for detecting physiological function, for example, nerve conduction, is described. In one embodiment the apparatus includes a housing including a stimulator shaped to fit a first anatomical site and a detector shaped to fit a second anatomical site. The housing automatically positions the detector substantially adjacent to the second anatomical site when the stimulator is positioned substantially adjacent to the first anatomical site. The detector contains a plurality of individual detection elements, whereby the response evoked by stimulation at the first anatomical site is measured using one or more of these detection elements at the second anatomical location.
