Electroneurography (ENG / NLG)
If damage to a peripheral nerve is suspected, e.g. due to compression (in carpal tunnel syndrome), or in the context of a disease affecting several nerves (e.g. polyneuropathy), an electroneurography is performed.
For this purpose, the nerves to be examined are stimulated with light impulses, and the resulting potentials can be derived via the corresponding muscles. This allows the electrical nerve conduction velocity (NLG) to be assessed.
