A rehabilitation stimulator is a physiotherapeutic device. A patient is subjected to currents using electrodes and it brings the required results in the patient. The different current types are available and used for various functions. In the proposed system the currents are produced with the help of a microcontroller which makes it more accurate, compact and cost effective. The programming is done in assembly language using microcontroller 89C51. The prototype is implemented and user interface was provided by a matrix keyboard and LCD. Current can be subjected to the patient via surface electrodes. There are few contraindications where in the rehabilitation stimulator should be avoided.
