Single-fiber electromyography (SFEMG) is useful in the evaluation of disorders of neuromuscular transmission and the assessment of motor unit morphology. Standard EMG techniques are used routinely in the evaluation of laryngeal dysfunction, but the feasibility of laryngeal SFEMG has not been established. We, therefore, performed laryngeal SFEMG in 10 normal individuals to demonstrate the feasibility of the technique and generate preliminary normative data. We also studied 2 patients with amyotrophic lateral sclerosis and 1 patient previously treated with botulinum toxin for comparative purposes.
