Diagnostic Services



The diagnosis of neuromuscular disease requires careful clinical and diagnostic assessment. Dr. Gupta is specially trained in neuromuscular disease, clinical neurophysiology and electrodiagnostic medicine to provide a thorough assessment of your condition.

We Provide the Following Services at the Clinic:

EMG (Electromyography) and Nerve Conduction Studies (NCS)

EMG is a test used to measure the electrical activity of your muscles. An EMG is often done in conjunction with a Nerve Conduction Velocity study, which measures how well and fasts the nerves can send electrical signals. Nerves use these electrical signals, called impulses, to control your body’s muscles to react in specific ways. Problems with either your nerves or muscles can cause your muscles to react in abnormal ways.

If you have pain or numbness in your legs, these two tests may help find out how much your nerves are being affected. These tests can also check how well your spinal nerves and the nerves in your arms and legs are working.

Why The Tests Are Done

An EMG is done to:

  • Assist in diagnosing diseases that damage muscles, nerves, or the junctions between nerves and muscles. These problems may include a herniated disc, amyotrophic lateral sclerosis (ALS) or myasthenia gravis (MG).
  • Assist in finding the cause of weakness, paralysis, or muscle twitching. These issues are symptomatic of problems in a muscle, the nerves supplying a muscle, the spinal cord or the area of the brain that controls a muscle.

A nerve conduction study is done to:

  • Find damage to the nerves that lead away from the brain and spinal cord and the smaller nerves that branch out from those nerves called the peripheral nervous system. This test is often used to help find nerve problems such as carpal tunnel syndrome or Guillain-Barré syndrome.

How to Prepare for Your EMG and Nerve Conduction Studies

Skin Biopsy is an easy and minimally invasive technique that allows us to exam the small sensory nerves in the skin for the diagnosis of small fiber neuropathy (SFN).
