Nerve Conduction and Electromyography


Nerve Conduction and Electromyography are used to evaluate nerve and muscle injuries.


Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons).

Motor neurons transmit electrical signals that cause muscles to contract. An EMG translates these signals into graphs, sounds or numerical values that a specialist interprets.

An EMG uses tiny devices called electrodes to transmit or detect electrical signals.

During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle.

A nerve conduction study, another type of EMG, uses electrodes taped to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points.

EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

Nerve Conduction Study and EMG are diagnostic tools commonly used to evaluate the functional level of electrical conduction of the sensory and motor nerves.

Nerve Conduction Studies and EMG are used mainly for the evaluation of paresthesia (numbness, tingling, burning) and/or weakness of the arms and legs. The study is used to evaluate conditions such as:
• Carpal Tunnel Syndrome
• Nerve injury of the upper and lower extremities
• Pinched nerve in the lower back and neck
• Neuropathy
