Clinical Trial 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.

Description:

When an individual contacts the PI or the department research coordinator, a preliminary screen will be administered for any obvious exclusion. If there are no exclusions, the first visit will be scheduled. At this initial visit, a full description of the study and exercise protocol will be provided. A health history questionnaire and an EAT-10 questionnaire will be administered.

If consent is obtained, baseline tongue strength will be measured using the IOPI device. Individuals with Parkinson's will be randomized to exercise with the COSD or with the tongue depressors. Those who will use the COSD will be start with no less than 60% max strength and receive an exercise log. Those using the tongue depressors will also receive an exercise log.

All participants will receive a full demonstration of the exercise and will be asked to return the demonstration.

The second visit will be scheduled for all participants the following week. At that time, the EAT-10 and tongue strength will be re-assessed. The exercise logs will be reviewed to ensure compliance. Participants using the COSD will be issued a new device that is no less than 80% of their max strength.

The third visit will be scheduled the following week (week 3). The EAT-10 questionnaire and tongue strength will be reassessed. The exercise log will be reviewed for compliance. COSD will be inspected for any signs of wear and a new one will be issued if the device appears worn.

The last 2 visits will be scheduled during weeks 6 and 8 of the exercise protocol. The EAT-10 and tongue strength will be re-assessed, and the exercise log will be reviewed for compliance. The COSD will be inspected for any signs of wear and a new one will be issued if the device appears worn. In addition, during the final visit, all participants will be asked to complete a questionnaire regarding their satisfaction with the exercise device they were assigned. The COSD will be collected at that visit.

• Parkinson Disease

Intervention

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.
• 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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.
