Electrical
currents in your organs and tissue control many of your bodily
functions. Nerve conduction velocity (NCV) and
electromyography (EMG) tests record these electrical currents,
helping physicians diagnose nerve and muscle problems. The NCV,
which measures the speed at which your nerves carry electrical
signals, will be performed before the EMG, which analyzes the
nerve impulses within certain muscles.
Carpal Tunnel
Syndrome
An X-ray may be
taken to check for other causes of the complaints such as
arthritis or a fracture. An NCV or nerve conduction study and
EMG may be done to check for other sites of nerve
problems as well as to evaluate the carpal tunnel.
