title: Continuous positive air pressure eliminates nocturnal stridor in multiple system atrophy. Barcelona Multiple System Atrophy Study Group.
abstract: We prospectively studied the sleep patterns and laryngeal function of 20 patients with multiple system atrophy and found sleep disturbances in all subjects and vocal cord abduction dysfunction in 14 (70%). In three patients with nocturnal stridor and complete vocal cord abductor dysfunction, continuous positive airways pressure eliminated laryngeal stridor, obstructive apnoea, and haemoglobin desaturation.
