The machine displays waves and spikes on the monitor, which will be interpreted by your Doctor to diagnose the conditions you are suffering from.
On average 30-60 minutes are usually taken to perform EMG or NCV tests.
Procedure for EMG test:
- You will be allowed to either sit or lie on the examination table.
- Your body area to be tested is cleaned properly.
- Then needle electrode will be placed into the muscle to measure electrical activity in your muscles. When the electrodes are inserted then you may feel slight pain or discomfort.
- These electrodes will transmit signals which are then recorded in the machine connected.
- After placing electrodes, you will be asked to contract and relax muscles and the machine will record this activity.
- The machine displays waves and spikes on the monitor, which will be interpreted by your Doctor to diagnose the conditions you are suffering from.
Procedure for Nerve conduction velocity(NCV) Test:
- You will be allowed to either sit or lie on the examination table.
- One or more electrodes are attached to the part which need to be tested.
- These electrodes deliver a mild electrical impulse which may be perceived as painful by some people.
- Response to electrical stimulation from nerves is recorded and analyzed. The speed at which response is produced and impulse travel in your nerves is called as nerve conduction velocity.
