title: Jitter analysis with concentric needle electrodes.
abstract: Because of certain restrictions in medical praxis, reusable materials are only allowed in some countries. This also applies to electrodes for electromyography; the special single-fiber electromyography electrode must be replaced. This article gives some details of the possibilities of using an alternative-a small concentric needle electrode. Practical hints, reference values, and the application in diagnostic work for myasthenia gravis are summarized.
