Doctors recommend nerve conduction studies or NCV Tests for those who develop the symptoms like numbness in fingers, tingling in arms or legs, or experiencing weakness in arms and legs.

NCV test at home is conducted along with an EMG which points out the difference between a nerve and a muscle disorder. Moreover, Nerve Conduction Velocity determines any problem affecting the nerve, whereas an EMG detects the working of the muscle in response to the stimulus of the nerves.
