Nerve conduction studies are used to assess if there is any possible damage to your nerves in your wrists, fingers and forearm, and also studies how well and how fast your nerves send impulses in your body.
A nerve conduction study test is a non-invasive procedure. During the test, electrodes are placed on your hand and wrist. The electrodes then produce a small electrical current which stimulates the nerves in the wrist, fingers, and forearm. Although it is a little uncomfortable, there are no side effects.
During an EMG, a needle shaped electrode is inserted into the muscle. The electrical activity is measured whilst the muscle is at rest, then your specialist will ask you to contract the muscle to measure the activity.
Your doctor will advise whether you need to stop certain medications before the procedure, such as Warfarin or aspirin. It is advisable to wear loose fitting clothing for your own comfort, and ensure the area which is going to be tested is clear of body oils, sprays, or creams.
After the procedure is complete, you will be able to go home as soon as you wish.
If you have an EMG, it is advisable to have someone take you home as you may have some tenderness in the muscle after.
Nerve study test’s and EMG’s are both very safe procedures. Your doctor or surgeon will discuss any risks with you beforehand.
