Abstract
A transcutaneous nerve stimulating device is provided having a plurality of operating modes, namely burst, normal (single amplitude/single pulse width), rate modulation, amplitude modulation and strength-duration/rate modulation. In the lattermost mode, the rate modulation control circuitry acts independently of the inter-related amplitude and pulse width modulations to result in a means of nerve stimulation obviating the phenomenon of accommodation.
