EMG Testing and Nerve Conduction Studies: Assessing Health of Muscles, Neurons

Electromyography (EMG testing) and nerve conduction study (NCS) are diagnostic tests that are performed in order to assess the health of muscles and motor neurons.

Motor neurons are the nerves that are responsible for the muscles’ contractions, and damaged or dysfunctional motor neurons can cause health conditions like muscle and nerve disorders.

During the exam, we will monitor the electrical activity that occurs within the muscles at rest and when the muscles are slightly contracted. EMG testing measures the electrical activity within the muscles and can help physicians diagnose any potential problems with nerve-to-muscle signal transmission, nerve dysfunction, and/or muscle dysfunction.  

Why Should I Get an Electromyography?

EMG tests can be used to diagnose conditions like muscle disorders, disorders of the nerves, and conditions that affect the nerve root, motor neurons, and/or connections between the nerves and muscles.

Common symptoms that may indicate a muscle or nerve disorder can include:

  • Pain or cramping in the muscles
  • Tingling
  • Numbness
  • Muscle weakness
  • Some forms of limb pain

How is EMG Testing Performed?

This diagnostic procedure is formed by placing surface electrodes or inserting needle electrodes in various locations on your body. You may experience a mild twinge or spasm as the electrode delivers an electrical current to the designated area. You may be asked to contract your muscles during the procedure so the physician can monitor the electrical activity generated in your muscles during movement and at rest.

Where Will the Test be Performed?

If you have been given a prescription for an EMG/NCS test, please schedule your appointment at your earliest convenience. We recommend you return for a follow-up visit to Dr. Arora’s office at least one week after your EMG test to allow enough time for us to obtain the results. We recommend you confirm that we have received the results in our office before you return for your follow-up visit.

Dr. Arora works closely with a few select practices in the areas around each office to co-ordinate EMG testing.

Recommendations will be given at the time of your appointment.

Contact our doctor’s office in West Bloomfield, Howell, St. Clair Shores, or Macomb today for further information or to schedule a consultation. We look forward to hearing from you!
