Brief Summary
University of Colorado is looking for adults with Parkinson's disease to participate in a research study. The study aims to explore how a novel low technology device can achieve an increase in tongue strength comparable to standard of care exercise using tongue depressors but with the kinematics and simple biofeedback of existing high cost devices. Research has shown that tongue resistance exercises paired with biofeedback have resulted in improved tongue strength to support chewing, control of food and liquid in the mouth, and propulsion of material for a swallow.

Outcome Measures
Primary Outcomes (1)
Change in Tongue Strength, as measured in kPa via IOPI
Tongue Strength, as measured in kPa via IOPI with measurements that are equal to or higher compared to baseline at follow-up visits at weeks 2,3,6 and 8 from initial visit. Tongue strength will be assessed using The Iowa Oral Pressure Instrument (IOPI). IOPI measures tongue strength with max pressure (kPa) ranging from 0 to 110 with an average of 50-60 kPa depending on age. Higher kPa is associated with increased tongue strength.
Baseline, up to 8 weeks.
Study Arms (2)
COSD
EXPERIMENTALParticipants assigned to the COSD, will use the investigational device.
SOC
ACTIVE COMPARATORTongue depressors are the standard-of-care so the control group will use these instead of the investigational "Colorado Oral Strengthening Device."
Interventions
The exercise protocol will include using the tongue to compress the COSD against the hard palate, or against the tongue depressor for 30 repetitions, 3 times per day, on 3 days of the 7-day week. For the first week, the participants who are in the COSD group will be issued a COSD bulb that corresponds to no less than 60% of their baseline maximum strength. After week 1, they will switch to a COSD bulb that corresponds to no less than 80% of their maximum tongue strength for the remaining 7 weeks.
The exercise protocol will include using the tongue to compress the COSD against the hard palate, or against the tongue depressor for 30 repetitions, 3 times per day, on 3 days of the 7-day week. For the tongue depressor group, they will be given 8 tongue depressors, which are disposable, for the duration of the study.
