- 1. 筋電図検査の概要overview of electromyography [show details]
…The electrical activity from these individual muscle fibers summates to generate a motor unit action potential (MUAP) . This results in a waveform that is characteristically triphasic : A positive (downward) … the time between when the MUAP signal leaves the baseline to when it returns) Number of phases (eg,…
- 2. 神経伝導検査の概要overview of nerve conduction studies [show details]
… Sensory nerve action potentials (SNAPs) and compound muscle action potentials (CMAPs) are compound potentials that… able to record smaller SNAPs in diseases of nerves, especially with digital averaging to increase signal-to-noise ratio . Surface recording electrodes are typically used to record the electrical activity …
