Nerve Conduction Studies ( NCS)
This study allows the physician to determine if a patient has any damage or injury to the peripheral nerve, such as when Carpal Tunnel Syndrome or Sciatic neuropathy occurs.
The nerve is stimulated with very mild electrical impulses while recording electrodes pick up nerve activity. The distance between the stimulation site and recording site is then measured, allowing for determination of such parameters as distal latency and conduction velocity. Several nerves are studied during the evaluation. In most cases the results of the study are available immediately, however your physician may often need additional time to analyze the collected data to ensure accuracy of the test. In most cases Nerve Conduction and EMG tests are performed during the same visit.
A very small needle electrode is inserted into the muscle during this test. As your muscle naturally provides electrical impulses, these signals are recorded and then interpreted by computer. EMG is a very important part of electro diagnostic evaluation as it allows your physician to determine not only the presence of muscle denervation or damage but the severity and chronicity of such. Electromyography is also extremely useful to ensure accuracy of muscle injection during Botox treatment.
All our physicians received extensive training in electro diagnostics. NCS and EMG are studies designed to evaluate the severity or presence of such conditions as Carpal Tunnel syndrome, lumbar or cervical radiculopathy, peripheral neuropathy, myopathy, Myasthenia Gravis, Guillain-Barre syndrome and a variety of other muscle and nerve disorders.
