A battery-powered constant current stimulator for motor end-point detection.
The device described was developed as an external electrical stimulator to assist in the accurate location of motor end-points prior to the injection of nerve blocking agents in the treatment of spasticity. Monophasic pulses are produced with a duration of 10-100 microseconds and a current from 0 to 10 mA. The current is maintained over a wide range of electrode impedance and is independent of battery voltage.
