Call to schedule a NVC/EMG study.

Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons). EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle communication. Motor neurons transmit electrical signals that cause muscles to contract. An EMG uses tiny devices called electrodes to translate these signals into graphs, sounds or numerical values. During a needle EMG, a needle electrode  is inserted directly into a muscle  and records the electrical activity in that muscle.


Nerve Conduction Velocity (NCV) measures the speed at which an electrical impulse travels along a nerve. During an NCV, patch-like electrodes are applied to your skin in several places over the nerve to be tested. Low-level electricity is dispensed through the electrodes to stimulate the nerve. The amount of electricity is similar to a shock from static electricity. The velocity, or speed,  at which the electrical signal flows through the nerve is measured and displayed on a screen. The information from these studies is combined and interpreted by a specialist.

   Tracy Norvell, PT, OCS is certified by the American Academy of Clinical Electrodiagnosis and the State of Washington in performing nerve conduction and electromyography testing. She is able to perform and interpret studies for upper and lower extremity peripheral nerve entrapments, peripheral neuropathies, radiculopathies, myopathies, and lower motor neuron diseases.
