Welcome to our EMG / NCS Review Flashcards! Understanding is paramount, but unfortunately, one aspect of academic success does rely on simple memorization and repetition. In our neurology flashcards feature, we have taken the most commonly seen rote memory topics and “buzzwords” from neurology board and RITE* exams and made easy to use flashcards. These work on desktop, tablet, and mobile devices.
Compound Motor Action Potentials (CMAPs)
EMG insertional activity finding in muscle necrosis
Increased EMG insertional activity is seen with...
Irregular spontaneous firing of a motor neuron at rest. "Popcorn popping" sound on EMG. When they are frequent, they can represent acute muscle denervation. Widespread fasciculations involving can be seen in motor neuron disease (ALS), benign fasciculation syndrome, and cramp fasciculation syndrome.
Disorders of increased and decreased recruitment
EMG findings in chronic neuropathic lesions
