How Neurologists Perform Nerve Conduction Studies (EMG/NCV) to Evaluate Neuropathy

At the Center for Neurological Treatment & Research in Nashville, TN, Dr. Richard Rubinowicz uses advanced diagnostic tools like nerve conduction studies (NCV) and electromyography (EMG) to evaluate neuropathy. These tests provide valuable insight into the health of your nerves and muscles, allowing for accurate diagnosis and targeted treatment.

Understanding Neuropathy

Neuropathy is a condition in which nerves are damaged or disrupted, leading to numbness, tingling, burning, or muscle weakness. Diabetes, autoimmune diseases, infection, trauma, or exposure to toxins can cause neuropathy. Because of the tendency of neuropathy to disguise other medical conditions, it is necessary to identify the exact cause of neuropathy to be able to treat it effectively. Without proper diagnosis, symptoms will improve or progress, compromising quality of life.

What Happens During a Nerve Conduction Study

A nerve conduction test determines how efficiently electrical signals pass through your nerves. For the test, small electrodes are taped to the skin over a particular nerve. A weak electric shock is used to stimulate the nerve, and sensors measure how fast and well the signal gets through. This procedure uncovers whether there is a delay or blockage in nerve signal transmission. By comparing answers from different nerves, Dr. Rubinowicz can determine if the problem is generalized or localized and thus guide treatment.

How EMG Complements the Test

Electromyography (EMG) is normally performed along with NCV to obtain a complete picture of muscle and nerve function. While NCV assesses the ability of the nerve to transmit signals, EMG examines the electrical activity in the muscles themselves. An electrode placed in some muscles detects electrical activity at rest and with movement using a small needle electrode. Abnormal patterns will show whether the issue lies within the nerves, the muscles, or the interface between the two. The tests combined can distinguish between nerve illnesses, such as peripheral neuropathy, and muscle illnesses, such as myopathy.

Why These Tests Matter

EMG and NCV testing provide detailed information that a physical examination alone cannot uncover. They allow for the identification of the location, severity, and type of nerve damage, whether it involves sensory nerves, motor nerves, or both. This level of precision ensures that treatment plans address the root cause rather than just managing symptoms. For patients, this often means faster relief, better function, and improved long-term outcomes.
