Single-fiber electromyography (SFEMG) is a selective electromyography (EMG) recording technique that uniquely identifies action potentials (APs) from individual muscle fibers, thus allowing measurement of fiber density (FD) and neuromuscular jitter. FD quantifies the local concentration of muscle fibers within a motor unit and is a sensitive measure of reinnervation. Jitter is the most sensitive in vivo measurement of transmission across the neuromuscular junction and is particularly useful in demonstrating abnormalities associated with myasthenia gravis (MG) and related conditions.
