6. MUSCLE STIMULATOR
6.1 INTRODUCTION
The neuro-muscular stimulator stimulates the nerves (neurons) of the part of the body to which the electrodes are attached. It provides relief for headache, muscular pain, or fatigue (due to exertion of muscles) and also revives the frozen muscle which impairs movement. The main function of this electronic instrument is to provide energy to nerve of the muscle and to remove cellulites.
Current stimulator is one of the most commonly used instruments used for diagnosis and treatment of a wide variety of neurological and muscular disorders. It works by forcing electric current into a human system, to elicit information to treat the system.
The muscular stimulator circuit generates 150 µs pulses at 80 Hz frequency, which is then given to the secondary of the transformer to generate 60V positive and 150V negative peaks at very low current so that the patient in not subjected to any shock. The intensity of the current can be varied by changing the resistance which is connected to the pulse generator. Pulse generator is the heart of the circuit involves CMOS timer (7555) to generate pulse train.
