What is EMG?
Electromyography (EMG) is a nerve test that evaluates the electrical condition of the neuromuscular function. EMG includes many procedures such as needle EMG testing, nerve conduction studies, H-reflex studies, F-waves studies as well as other procedures. H-reflex studies are used here to represent the EMG procedures. It is recorded using surface electrodes that are applied on the skin of the legs or the arms while electrically stimulating some of the leg or arm nerves (with surface electrodes). The patient will feel electrical pulses and the foot or the hand moves involuntarily. It is rather inconvenience for some patients who do not like small electrical pulses. Such sensation is more prominent in the first 5 min. during testing after which sensation is easily tolerated by almost every body.
