Review examines neurological causes of unusual vocal-cord movement

Researchers conducted a systematic review of published human studies on paradoxical vocal fold motion linked to confirmed disorders of the brain, spinal cord, nerves, or related systems. Across 11 included studies, 42 patients were identified with both this vocal-fold movement problem and a confirmed neurological disorder. The findings describe reported associations and treatment outcomes; they do not establish how common these causes are or prove that one condition caused another.
