Sammanfattning
BACKGROUND A number of evidence-based guidelines now recommend that a nerve conduction study should be used to confirm the existence of carpal tunnel syndrome before any surgery takes place.
METHOD The article is based on a search in PubMed, a personal literature archive (1980?–?2011) and long clinical experience of neurological and neurophysiological diagnostics.
RESULTS Both motor and sensory nerve fascicles must be tested after adequate warming up. An extended nerve conduction study with supplementary tests to compare velocities and latencies in median and ulnar nerves, increases the diagnostic precision. Given normal or mild findings, surgery can usually be avoided as the first choice of treatment, because many patients with mild carpal tunnel syndrome recover spontaneously.
INTERPRETATION The gold standard for diagnosis of carpal tunnel syndrome should be a combination of a clinical examination and a nerve conduction study.
