DBS Frequency on Swallowing Function in Parkinson's Disease
Effects of the Stimulation Frequency of STN DBS on Swallowing Function in Patients With Parkinson's Disease
Studie Overzicht
Gedetailleerde beschrijving
This is the first study on the effect of the stimulation frequency on swallowing function in PD patients with STN DBS. Swallowing dysfunction is often difficult to treat pharmacologically and associated with increased morbidity and mortality. This study hence would have significant clinical implications in the management of swallowing dysfunction in these PD patients with STN DBS and could potentially decrease their morbidity and mortality.
The investigators expect that the traditionally high frequency stimulation of 130 Hz would worsen while the low frequency stimulation of 60 Hz would improve the swallowing function in OPMS summary

The primary outcome would be the OPMS swallowing function scores
Tijdsspanne: One year
|
Eight PD patients with STN DBS and FOG responsive to stimulation frequency changes will be enrolled.
Information on the oropharyngeal motility study (OPMS) of the oral, pharyngeal and esophageal phase function will be collected, under "Med on/DBS off", "Med on/DBS 130 Hz", or "Med on/DBS 60 Hz".
Each patient will be randomly assigned to these three conditions in a double blinded manner of 30 minutes apart.
The patients will be reassessed under the single best condition (likely Med on/DBS 60 Hz) after being on for 6-8 weeks.
ANOVA will be used for group comparison of the scores.
A regression model will be further used to assess the predicting value (s) of the other scores and demographics for the swallowing function.
