EMG & NCS

What is Electromyography (EMG) and Nerve Conduction Studies (NCS)?

Electromyography and Nerve Conduction Studies, or EMG/NCS, is the recording of the electrical activity in the muscles and nerves. The study used small devices called electrodes to measure electrical signals transmitted by neurons. The electrodes are taped to the skin in order to gather recordings of the speed and strength of the signals as the muscles contract and relax.

Symptoms That May Require EMG/NCS

  • Numbness
  • Muscle Pain
  • Muscle Cramping
  • Limb Pain

  • Rare complications
  • Very low risk
  • Small risk of bleeding at needle injection site
  • Infection or nerve injury at needle injection site
  • Possible lung collapse with needle injection in muscle of the chest
