EMG/NCS tests are used to diagnose nerve and muscle disorders in patients with symptoms such as numbness and tingling of extremities, burning of the feet, pain and weakness of extremities.

The EMG requires the insertion of a small needle that records muscle responses. NCS involves giving a patient small electrical stimuli causing the hand or foot to twitch. These procedures aid in the diagnosis of:


  • Carpal tunnel syndrome
  • Peripheral neuropathy
  • Peroneal nerve compression
  • Proximal neuropathy such as Guillain-Barré syndrome
  • Motor neuron diseases such as amyotrophic lateral sclerosis (ALS)
  • Nerve root compression/lesions such as radiculopathy from a ruptured disk
  • Plexopathy
  • Muscle disorders such as myopathy, myositis, muscular dystrophy, neuromuscular junction diseases such as Myasthenia Gravis and Eaton-Lambert Syndrome
