Which pathologies can be evaluated with nerve conduction studies?

Nerve conduction studies (NCS) are specialized tests that evaluate the electrical conduction of peripheral nerves. They are particularly useful in diagnosing and assessing various neurological conditions that affect nerve function.

Carpal tunnel syndrome, for instance, is a common condition caused by compression of the median nerve at the wrist. NCS can identify decreased conduction velocity or increased latency in this nerve, confirming the diagnosis and assessing the severity of the condition.

Neuropathies, which include a range of disorders affecting nerves, can be evaluated through nerve conduction studies by examining the electrical signals of affected nerves. This allows for differentiation between the types of neuropathies, whether they are due to metabolic conditions, entrapment, or hereditary factors.

Radiculopathies, which involve nerve root compression typically stemming from a herniated disc or other spine-related issues, can also be assessed. NCS helps in determining if the electrical activity is affected in the regions supplied by the compressed nerve root.

Thus, the ability to evaluate these specific pathologies makes nerve conduction studies a crucial tool in the diagnosis and management of peripheral nerve disorders.
