Research Objectives
To investigate perceptions of dysphagia in Parkinson's disease prior to initiation
of the LSVT LOUD program.
To investigate perceived improvement in swallowing following completion of the LSVT
LOUD program.
Design
The research methodology is a prospective case study with data being collected from
September 2020, to October 2020.
Setting
The study setting was an outpatient speech language pathology office within a medical
facility.
Participants
67 year old male with a diagnosis of Parkinson's disease with deep brain stimulator.
Interventions
LSVT LOUD tune up sessions.
Daily homework: 1-2x daily.
Carryover assignments: Daily.
Main Outcome Measures
1) Qualitative interview
2) The Dysphagia Handicap Index (measures the effect of dysphagia on three aspects
of their lives 1) physical, 2) functional, and 3) emotional)
3) Voice Handicap Index.
Results
Case study findings revealed changes from pre and post- LSVT LOUD tune-up sessions
for two out of the three self-rated dysphagia perception measures. The physical perceptions
(sensations of choking), emotional perceptions (fear of choking) improved from a moderate
to a minimal perceived problem. Functional perceptions (avoidance of eating) remained
unchanged at a normal level of a perceived problem.
Conclusions
Research indicates that with Parkinson's disease an individual's self-perception of
functioning is not a reliable indicator of actual function. That is, their current
ability to ambulate, communicate, and swallow may be more impaired than perceived.
However, it is still important to include input from the individual as part of evidence-based
practice guidelines. In this case study, the emotional perception of swallowing ability
following tune-up sessions improved and may correlate to improved quality of life
overall. Questions remain and include whether the perception of improved swallowing
may relate to improved compliance with a comprehensive treatment protocol as well
as overall quality of life and health. Additional research is needed to compare dysphagia
perceptions of improvement after tune-up sessions and after the complete LSVT-LOUD
program.
