OBJECTIVE: To examine relations between peak expiratory (cough) airflow rate and
swallowing symptom severity in participants with Parkinson disease (PD). DESIGN:
Cross-sectional study. SETTING: Outpatient radiology clinic at an acute care
hospital. PARTICIPANTS: Men and women with PD (N=68). INTERVENTIONS: Participants
were cued to cough into an analog peak flow meter then swallowed three 20-mL thin
liquid barium boluses. Analyses were directed at detecting potential relations
among disease severity, swallowing symptom severity, and peak expiratory (cough)
airflow rate. MAIN OUTCOME MEASURES: Peak expiratory (cough) airflow rate and
swallow symptom severity. RESULTS: Peak expiratory (cough) airflow rate varied
significantly across swallowing severity classifications. Participants with more
severe disease displayed a significant, linear decrease in peak expiratory
(cough) airflow rate than those participants with earlier stage, less severe
disease. Swallowing symptom severity varied significantly across groups when
comparing participants with less severe PD with those with more severe PD.
Participants with early stage PD demonstrated little to no swallowing symptoms
and had the highest measures of peak expiratory (cough) airflow rate. In
contrast, participants with the most severe swallowing symptoms also displayed
the lowest measures of peak expiratory (cough) airflow rate. CONCLUSIONS:
Relations existed among PD severity, swallowing symptom severity, and peak
expiratory (cough) airflow rate in participants with PD. Peak expiratory (cough)
airflow rate may eventually stand as a noninvasive predictor of aspiration risk
in those with PD, particularly those with later stage disease. Inclusion of peak
expiratory (cough) airflow rates into existing clinical swallowing assessments
may increase the sensitivity and predictive validity of these assessments.
