Which statement about nerve conduction studies is true?

Nerve conduction studies (NCS) are diagnostic tests used to evaluate the function of peripheral nerves. The statement that they provide information about both motor and sensory nerves is accurate. NCS assess the electrical conduction velocity and amplitude of signals in nerves, allowing for the evaluation of motor fibers, which control muscle movements, as well as sensory fibers that transmit sensory information. This dual assessment is essential for diagnosing various neurological conditions, as it helps healthcare providers determine the presence and extent of nerve damage or dysfunction in both types of nerve fibers.

The ability to evaluate both motor and sensory nerves makes this technique versatile and valuable in clinical practice, aiding in the identification of peripheral neuropathies, nerve entrapments, and other related issues. By analyzing the conduction properties of these different nerve types, clinicians can gain a comprehensive understanding of a patient's nerve health and potential pathologies.
