Participant Flow

Two iterations of the sensors were tested against commercial sensors. For iteration 1, 51 healthy older adults were screened for eligibility between September and November 2018. For iteration 2, 38 healthy older adults were screened for eligibility between October 2021 and March 2023. All was completed at a university research lab and clinic in West Lafayette, Indiana.

For iteration 1, 40 of the 51 participants were randomized into one of 2 groups for testing 1. Of those not randomized, 7 did not meet inclusion criteria, 1 declined to participate, and 1 did not participate due to other reasons (scheduling conflicts or technical issues). For iteration 2, 30 of the 38 participants were randomized into one of 2 groups for testing 2. Of those not randomized, 7 did not meet inclusion criteria, and 1 did not participate due to other reasons (technical issues).

Group A1: Conventional Sensors First, Then Experimental (Tele-EaT) Sensors - Iteration 1
Group A1 participants completed the experimental protocol (swallow trials) with the conventional (commercially available) electrodes/sensors first. After a break of 10 minutes, they then repeated the exact same experimental protocol (exact same swallow trials) with the first iteration of the experimental sensors (i.e., a wearable surface EMG sensors patch we are developing). Tele-EaT Sensors - Iteration 1: A first iteration of a wearable surface EMG (sEMG) sensors patch we developed was tested against commercially available wired devices. The first iteration of the wearable sensor patch is an ultrathin patch with a honeycomb-inspired design that included sEMG and strain sensors in order to capture muscle activity and thyroid movement signals from the submental area during swallows and swallow maneuvers/exercises. Participants performed standardized swallow tasks while wearing the first iteration device. Conventional Sensors: Conventional sensors included snap-on wired electrodes as the control condition. The same set of standardized swallow tasks was completed with the conventional and commercially available devices as well.

The second iteration of the wearable sensor patch is a more durable slightly thicker flexible, non-stretchable, and double-sided thin sEMG patch. Participants performed standardized swallow tasks while wearing the second iteration device. Conventional Sensors: Conventional sensors included snap-on wired electrodes as the control condition. The same set of standardized swallow tasks was completed with the conventional and commercially available devices as well.

PRIMARY outcome

Timeframe: Post each experiment (i.e., 1 hour after the sensors have been placed)

Population: Reminder: The first iteration testing of the Tele-EaT sensors was tested against commercial/conventional sensors in 40 participants. The second iteration testing was tested in an additional 30 participants.

Normalized sEMG amplitude values during standardized swallow tasks and maneuvers will be recorded and compared between the two sEMG devices. Normalized amplitude is used as a signal quality parameter and is not a health related outcome.

SECONDARY outcome

Timeframe: Post each experiment (i.e., 1 hour after the sensors have been placed)

Population: The first iteration test of the Tele-EaT sensors against commercial/conventional sensors included 40 participants. The second iteration testing was tested in an additional 30 participants.

Ease-of-use/comfort will be examined using a survey also devised by the investigators (using a positive centered 5-point Likert scale) with questions about ease-of-use/comfort after each experiment with each device. This survey includes statements related to the participants' ease-of-use/comfort during the experimental protocol (e.g., I was comfortable while the experimenter placed the sensors on my skin). The answers will be rated on a 10-point scale (i.e., 1 = extremely uncomfortable, 10 = extremely comfortable). Higher values indicate better or higher satisfaction/comfort scores. Total scores will be compared across conditions/devices tested. For the first iteration testing, the scale used for this outcome measure included 5 survey questions rated on a 10-point scale (total possible: 50; range 0-50). For the second iteration testing, we added one more question, hence the scale included 6 survey questions (total possible: 60; range: 0-60).

SECONDARY outcome

Timeframe: Pre and Post each experiment (i.e., right before the placement of sensors on the subject and 1 hour after the sensors have been placed and 5 minutes after their removal)

Population: Reminder: The first iteration testing of the Tele-EaT sensors was tested against commercial/conventional sensors in 40 participants. The second iteration testing was tested in an additional 30 participants. For this outcome measure, cumulative data across both time points are presented.

Safety will be examined by documenting the incidence of skin irritations and pain in the subjects. A visual inspection form including a binary scale (YES/NO) has been devised by the investigators (no formal name) and will be used by a rater who will thoroughly inspect the participants' submandibular skin before and after each experiment. For any irritation or change in appearance YES will be selected and the type of irritation will be descriptively recorded (e.g., red skin). Pain is also rated in the same way through a question to the participants. This form will be completed by a rater who is not part of the data collection process and who is blinded to sensors type to avoid any bias.The number of YESs will be used to calculate the incidence of these adverse effects in the sample.
