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.

Conditions

  • Parkinson Disease

Interventions

DEVICE

COSD

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.

DEVICE

SOC

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.
