In brainstem tumor surgery, routine motoring of brainstem function can be achieved by BAEP, SSEP, and MEP. In addition, stimulated or free-run EMG for the endangered cranial nerve (CN) or nucleus can be useful.
28 lis 2023 · Electromyography (EMG) and nerve conduction studies (NCS)–also called a nerve conduction velocity test (NCV)–are invaluable diagnostic tools used in neurology to assess and diagnose a wide range of neuromuscular conditions.
Electrodiagnostic studies are the gold standard for diagnosing and prognosticating nerve injuries. However, most surgeons are not trained in the interpretation of these studies; rather, they rely on the interpretation provided by the electrodiagnostician, who in turn is unlikely to be trained in nerve reconstruction.
A nerve can be repeatedly stimulated to evaluate the neuromuscular junction for fatigability; eg, a progressive decremental response occurs in myasthenia gravis. Techniques focusing on single-fiber conduction may be more sensitive for detecting changes associated with neuromuscular junction disorders such as myasthenia gravis.
Neurologists often perform an EMG test alongside a nerve conduction study (NCS). An NCS measures the flow of electrical current through a nerve before it reaches a muscle. An EMG measures the response of muscles to electrical activity and how much electrical activity a muscle contraction produces.
14 mar 2024 · Electromyography (EMG), a diagnostic test, measures how well your muscles respond to those signals. Movement is a complex interaction between your central nervous and muscular systems. Your...
