Airflow tracking in patients with ataxic disorders.
Source: Clinical Linguistics and Phonetics 13(6):433-447.
Abstract: Expiratory airflow control was tracked in 17 cerebellar disorder patients and 25 normal controls. An aerometer recorded airflow rate, visually fed back on a computer screen. Cerebellar disorder patients showed remarkable tracking deficits compared to the controls. Their tracking impairment had less related to perceptual and acoustic measures of dysarthria than to clinical ataxia scores based on limb examinations. Tracking skills did not improve over repetitive trials. However, there was a significant training-related gain in initiation of tracking tasks, which indicates a specific impairment of the tracking process.(CIRRIE Abstract)
