Respiratory Load Magnitude Estimation in PD

NCT02202057 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 30

Last updated 2016-09-19

No results posted yet for this study

Summary

The purpose of this study is to determine whether people with Parkinson's disease (PD) experience reduced perception of respiratory resistive loads versus healthy adults in the same age group. Further, the study will determine whether people with PD and trouble swallowing experience even more reduction of their perception of a respiratory resistive load.

Conditions

Interventions

OTHER

Respiratory resistive load on inhalation

The participant will be seated in a chair, and will be instructed to "relax and breathe" through a facemask. Five respiratory resistive loads (5-40 cmH2O resistive pressure) will be applied between 3-5 times during inhalation. Following each loaded breath, participants will rate the perceived difficulty of breathing in.

OTHER

Fluoroscopic swallowing evaluation

Participants with PD only will receive a swallowing evaluation as part of their routine clinical care. Generally, the standard clinical evaluation protocol consists of multiple swallows of thin liquid barium, pudding-thick barium, and a cracker or cookie coated with barium. Results are reviewed by the treatment speech-language pathologist, and for the purposes of this study, the researchers will review the most recently recorded swallow study and identify the worst observed penetration-aspiration (PA) score.
