Brief summary

Dysphagia in Parkinson's disease(PD) is common and its presence is related to motor and sensory abnormalities, and incoordination between swallowing and breathing. Despite harming as respiratory infections and increased risk of death, treatment of this condition remains uncertain. This study aims to evaluate the effect of oral motor exercises on the swallowing dynamics and quality of life of dysphagic Parkinson's disease patients. This study is an open trial, self-paired and blinded to the examiner. The participants will perform oropharyngeal exercises for five weeks and will be evaluated before and after intervention by swallowing videofluoroscopy and questionnaires about quality of life in dysphagia (SWAL-QOL).

Interventions

OTHERMotor exercises for swallowing, breathing and phonation

This exercises aimed to increase strength and range of motion of mouth, larynx and pharynx structures. All patients made sustained vowel phonation of /a/, pushing plosive phonemes /pa/, /ta/, /ka/ in a forceful manner, suction of wet gauze, swallowing with tongue hold and modified supraglottic maneuver, in ten repetitions, ascending and descending gliding phonation of vowel /a/ and /u/, five repetitions of each vowel, and tongue rotation in oral vestibule, 3 series of 5 repetitions to each side. Patients underwent oral motor exercises twice a day, five days a week, for five weeks.

Design outcomes

Primary

MeasureTime frameDescription
Oropharyngeal Swallowing Scorefive weeksBased on videofluoroscopy, were awarded points for the swallowing events according to their clinical relevance. The sum of these points results in the OSP (Oropharyngeal Swallowing Score), so that higher scores signify greater impairment in swallowing. OSP-score range from 0 to 243.5. This tool is being validated for that group.

Secondary

MeasureTime frameDescription
Quality of Lifefive weeksMeasured by the Swal-qol (Quality of life in Swallowing disorders). In this questionnaire the score range from 0 to 100 and higher scores is better quality of life.

Participant flow

Recruitment details

Consecutive patients from Movement Disorders Ambulatory of Federal University of Bahia in Brazil with idiopathic Parkinson disease (IPD) and complaint of dysphagia, from March 2009 to June 2010, were invited to participate.

Pre-assignment details

Patients with severe dysphagia who needed others interventions (for example: management of food consistency, alternative way of feeding) were excluded. During the study, subjects with absence in three sessions of exercises were excluded from the study and sent to Ambulatory of Speech and Deglutition Disorders at Federal University of Bahia.
