EMG findings in myasthenia often reveal characteristic patterns indicative of muscle weakness.

EMG findings in myasthenia often reveal characteristic patterns indicative of muscle weakness.

Correct answer is True: Electromyography (EMG) in myasthenia gravis typically shows abnormal patterns associated with muscle weakness. This can include a decremental response to repetitive nerve stimulation, especially at higher rates. Single-fiber EMG may also demonstrate increased jitter, reflecting irregularities in neuromuscular transmission. These findings contribute to the diagnosis and understanding of the neuromuscular involvement in myasthenia gravis.
