Electro-Diagnostic Testing    

NEUROLOGICAL TESTING CENTERS OF AMERICA is one of the most respected medical clinics in South Florida for the evaluation and treatment of neurological conditions and musculoskeletal abnormalities.  Our respected neurosciences program features highly specialized Neurodiagnostic Testing methods which help differentiate neurological conditions from other conditions with similar symptoms.  Data from these tests assists our neurosciences team to determine an accurate diagnosis in order to begin immediate, appropriate treatment.

Our neurological diagnostic tests include:

  *  Electromyography (EMG)            

  *  Nerve Conduction Velocity Test (NCV)

Electromyography (EMG)  is a test that assesses the health of the muscles and the nerves controlling the muscles.  During a needle EMG, a needle electrode inserted directly into a muscle, records the electrical activity in that muscle. The electrical activity detected by the electrode is displayed on an oscilloscope and may be heard through a speaker.  After placement of the electrodes, the patient may be asked to contract the muscle (for example, by bending the arm).  The wave form produced on the osciloscope provides information about the ability of the muscle to respond when the nerves are stimulated.  EMG testing helps to differentiate primary muscle conditions from muscle weakness caused by other neurologicial disorders.  EMG results can reveal nerve dysfunction, muscle dysfunction or problems with nerve-to-muscle signal transmission.

     

Nerve Conduction Velocity  (NCV)  is usually performed in conjunction with an EMG.  The test evaluates the speed of conduction of impulses through a nerve.  The nerve is stimulated, usually with electrodes that are placed on the skin.  One electrode stimulates the nerve with a very mild electrical impulse.  The resulting electrical activity is recorded by the other electrodes.  The distance between electrodes and the time it takes for electrical impulses to travel between electrodes are used to calculate the nerve conduction velocity.  This test is used to diagnose nerve damage or destruction.  Abnormal results can indicate peripheral neuropathy, damage to the spinal cord and other conditions.  

EMG and NCV results are often necessary to help diagnose or rule out a number of conditions such as:

    * Herniated Discs                       *  Radiculopathies                          * Peripheral Neuropathies

    * Carpal Tunnel Syndrome       *  Nerve Disfunction                       * Entrapment Neuropathies

    * Amyotrophic laterl sclerosis   *  Polio                                             * Mononeuropathy

    * Muscular dystrophy                 * Myasthenia Gravis                       * Polyneuropathy 


A physician may order an EMG and/or an NCV if a patient has signs or symptoms that may indicate nerve or muscle  disorder.  Such symptoms may include:

   * Tingling in the upper or lower extremities (arms, legs)

   * Numbness in the upper or lower extremities

   * Back and/or neck pain

   * Muscle pain, weakness, or cramping

   * Certain types of limb pain

   * Burning sensation in the extremities

   


Somatosensory Evoked Potential (SSEP) measures nerve impulses as they travel along the Central Nervous System.  Somatosensory Evoked Potential evaluates the sensory function from the peripheral nerves through the spinal cord and into the brain.  SSEP aids in the evaluation of:

   *  Herniated Discs                   * Spinal Cord Tumor                * Neuropathy & Radiculopathy

   * Spinal Trauma                      * Multiple Sclerosis                  * Myelopathy
