Nerve conduction studies are used to investigate how well the nerves in the body work. These studies are typically done when there is a question about potential nerve damage, for example from an injury
or from diabetes. Sometimes, it can be difficult to tell whether symptoms like pain or numbness
or weakness are coming from nerve damage or from another cause, and nerve conduction studies are designed to answer this question. This answer can potentially be very valuable, because it may change the way your symptoms are being treated.
Nerve conduction studies are not difficult, and they are tolerated very well by most people. Basically, small probes are used to send small electrical impulses through the nerves and muscles, and the time these impulses take to travel are measured.
There are a couple of types of medication that can affect the results of a nerve conduction study. In particular, muscle relaxants have to be stopped before the study. Similarly, medications with anti cholinergic side effects, such as certain anti histamines and medications used to treat nerve pain, will also need to be stopped. I suggest that you contact your neurologist
to get the full list of instructions in preparation for the procedure!
