What is the primary purpose of electromyography (EMG) in nerve conduction studies?

The primary purpose of electromyography (EMG) in nerve conduction studies is to assess muscle electrical activity and recruitment patterns. EMG is a diagnostic procedure that helps evaluate the health of muscles and the nerve cells that control them. Through EMG, clinicians can record the electrical activity of muscles at rest and during contraction, providing valuable information about the state of the neuromuscular system. This assessment can help identify neuromuscular disorders, such as muscle diseases or peripheral nerve damage, by highlighting abnormalities in muscle activation and responses.

This focus on evaluating muscle electrical activity and recruitment patterns is essential in clinical settings for diagnosing various conditions, tailoring rehabilitation strategies, and determining the functional capability of muscles in different scenarios.
