NERVE CONDUCTION STUDIES

A nerve-conduction study (NCS) is a specialised neurophysiological test that allows for the examination of peripheral nerve function. It works, by stimulating the nerves with a small electrical current while recording the signals distally using small electrodes placed upon the skin. Peripheral nerves should transmit signals within a considered normal range and any values outside of the normal range may indicate peripheral nerve dysfunction. This specialised study can be performed in isolation but can also be accompanied by another specialised study known as an electromyogram (EMG), depending on the clinical presentation and NCS findings. Once your test is complete the results are reviewed and interpreted by a consultant neurologist who determines if there are any abnormalities. A report will then be written outlining the findings of the study and will be sent to your referring doctor.
