EMG/NCS Testing

EMG/NCS (electromyography and nerve conduction study) is offered at ONSS.  EMG/NCS is a diagnostic procedure to assess the health of muscles and nerve cells that control them, and can help doctors diagnose nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signals.

The body’s nervous system is much like an electrical system in a building or vehicle.  Nerves and neurons are like wires that send messages to direct parts of the body to respond, move or react. An EMG uses tiny devices called electrodes to help detect signals between neurons and muscles. The test measures the speed and conductivity of the nerves. The test is conducted and interpreted by Dr. Judith Canlas at ONSC. 

Symptoms that may cause a doctor to order an EMG include:
 

• Tingling or numbness
• Muscle weakness, pain or cramping
• Certain types of pain or problems in the arms or legs

EMG can help diagnose or rule out a number of conditions, including:
 

• Muscle disorders
• Carpal tunnel
• Peripheral neuropathy
• Spinal problems
• Sciatic nerve issues
