Abstract:
1. An apparatus for self-diagnostic evaluation of nerve sensory latency, such as that which is symptomatic of carpal tunnel syndrome, comprising: (a) a power source; (b) a stimulator circuit configured for coupling to a first electrode at a first contact position on the skin of the user and for generating an electrical pulse from said power source at a selectable time; (c) a sense circuit configured for coupling to a second electrode at a second contact position on the skin of the user and for detecting the nerve response associated with the electrical pulse generated by the stimulator circuit as it arrives proximal to said second contact position; (d) a timer circuit configured for recording the time interval between the generation of the electrical pulse by the stimulator circuit and the arrival of the pulse response within the sense circuit; and (e) a display circuit operatively coupled to said timer and configured for displaying the time interval as recorded by the timer circuit.
