For example, excess alcohol consumption, hypothyroidism, diabetes, systemic diseases, or neurologic medications such as muscle relaxants, opioids, or psychotropic medications can all affect the results of a nerve conduction study. Chronic inflammatory polyneuropathy and neuropathyīefore starting a nerve conduction study, your neurologist will discuss possible factors that can affect the results of the study.Amyotrophic lateral sclerosis (ALS) aka: Lou Gehrig’s disease.Nerve conduction studies and EMGs can diagnose a variety of conditions, including: In some cases, both the nerves and muscles can be affected. Conducting these two diagnostic tests allows your neurologist to more accurately determine if the cause of the problem is a nerve disorder or if it has affected the muscles. Oftentimes, nerve conduction studies are performed in coordination with an electromyography (EMG), which is a test that measures electrical signals produced by the muscles when they are at rest versus when they are active.

Based on the results, your neurologist can determine if nerve damage has occurred, where it has occurred, and to what extent. A nerve conduction study, also known as nerve conduction velocity (NCV) test measures the speed of electrical impulses as they move through the nerves. Have you been experiencing numbness, tingling, or continuous pain with no known cause? If so, your neurologist may recommend having a nerve conduction study performed.
