Laryngeal electromyography and acoustic voice analysis in Parkinson's disease: a comparative study.

Unlabelled: Parkinson's disease (PD) involves a progressive depletion of dopamine in the basal ganglia leading to motor alterations. Oral communication impairment occurs in 75% to 90% of patients and has been poorly studied.

Aim: to asses laryngeal electromyography (LEMG) patterns and correlate them to vocal analysis in patients with Parkinson's disease.
