Electromyography & Nerve Conduction Velocity

  • Nerve Conduction Study (NCV): This test is done to diagnose the diseases of nerves,muscles & muscles – nerve junction.

      Nerves : Neuropathy, radiculo pathy, Plexopathy etc.
      Muscles : Myopathy, Spino muscular atropy, poly myositis etc.
      Myo-neural junction : Myasthenia Gravis etc

  • Electromyography ( EMG ): In EMG fine needle is put in muscles & we study the muscle action potential which helps us to differentiate whether weakness is due to involvement of muscles or nerves.
