The number of neural disorder cases has been continuously increasing every year. Rehabilitation, customarily besides being a long and arduous process, is also an expensive deal, which makes it beyond reach for the ordinary people. The inspiration for this project is to design a financial device that is compact, easy to use, and decreases the tedious and long duration of the recovery period.
Electronic Muscle Stimulator is a device, which is used for recovery of the patients suffering from strokes, spinal cord injuries, and other neural disorders. This device replaces physiotherapy sessions, which makes it economical and thus, accessible to all individuals.

EMG Sensor/Muscle Sensor Module interface with Arduino
EMG Sensor, also known as an electromyography sensor, is one that detects tiny electrical signals as you move your muscles. Sensors will measure the filter, the rectification of electrical activity in the muscle 0 - vs v, output size depend on the muscle activity
- Connect +Vs pin to the positive terminal of a battery.
- Connect -Vs pin to the negative terminal of another battery.
- Connect the positive and negative terminal of the two batteries to the GND pin of the sensor.
- Connect the SIG pin of the sensor to an analog pin on the Arduino.
- Connect the GND pin to the GND pin on the Arduino.
EMG (Electromyography) signals generated by the movement of muscles in the hand are acquired by surface electrodes. Acquired signals are then amplified, filtered, and conditioned. Further, this conditioned signal is transmitted to a microcontroller. On the reception of this signal, the micro-controller enables the EMS circuit via a switching circuit. The stimulus provided by the ems circuit is of a specified frequency and current intensity and is applied for a certain period. Accurate placement of stimulation electrodes ensures replication of the movement of the reference hand on to the imitation hand.
