Why is it essential to establish a baseline during nerve conduction studies?

Establishing a baseline during nerve conduction studies is crucial because it allows for the identification of significant changes that may indicate pathology. A baseline provides a reference point from which any subsequent measurements can be compared. If a patient's nerve conduction velocities, amplitudes, or latencies deviate from this baseline, it can suggest that a neurological disorder or injury has occurred.

When clinicians assess a patient’s nerve conduction data against their baseline measurements, they can more effectively detect abnormalities such as demyelination or axonal damage. This objective comparison is vital for diagnosing conditions such as peripheral neuropathy, carpal tunnel syndrome, or other nerve-related disorders. Without a reliable baseline, it would be challenging to differentiate between normal variations in nerve function and pathological changes that require intervention.
