Study Overview
Brief Summary
This project is being completed to test the usability and safety of the Watch-Transcutaneous Electrical Acustimulation (TEA) Device.
This is a pilot study that will lead to future projects for cancer patients that may experience chemotherapy-induced symptoms.
Detailed Description
This project will include three different aims (aim three is a clinical trial) and will be funded by the National Institute of Health (NIH). In aims 1 and 2 the device hardware and device application will be developed and will not be included in this registration as these are not clinical trials. However, aim three is being registered early in the project in order to obtain the Notice of Award (NOA) funding from the NIH. Once the NOA has been obtained the registration will be updated.

Outcomes
Primary Outcomes
Usability of the device for both groups day 3
Time Frame: Day 3
Questionnaires are administered online and there are 17 usability questions in the questionnaire. All answers use 0-to-5 scale (0 - no,1 - minor, 2 - some, 3 - considerable, 4 - major, 5 - critical) with a range of 0-85 with a higher score meaning more usable.
Number of adverse events related to the device noted on the safety questionnaire
Time Frame: 1-2 weeks (after baseline visit 1)
A safety questionnaire with 3 questions about skin irritation, pain, or infection. Visit 2 is at 1-2 weeks after visit 1.
Number of Transcutaneous Electrical Acustimulation (TEA)-related adverse events for both groups 3 days
Time Frame: Day 3
These will include skin irritation, pain, or infection under the Watch-TEA and tethered TEA devices after wearing each device for 3 consecutive days. Adverse events will be noted by the following: 1. \- Mild averse event (AE) - No treatment needed 2. \- Moderate AE - Resolved with treatment 3. \- Severe AE - Inability to carry on normal activities, required professional medical attention 4. \- Life-threatening or disabling AE 5. \- Fatal AE
Number of TEA-related adverse events for both groups 60 minutes at maximal tolerable level
Time Frame: Daily for 3 days
The subjects will self-apply the TEA for 60 minutes once daily with the current amplitude set at a maximal tolerable level. Events collected will include skin irritation, pain, or infection. Adverse events will be noted by the following: 1. \- Mild AE - No treatment needed 2. \- Moderate AE - Resolved with treatment 3. \- Severe AE - Inability to carry on normal activities, required professional medical attention 4. \- Life-threatening or disabling AE 5. \- Fatal AE

Number of non-treatment TEA adverse events for both groups
Time Frame: up to 1-2 weeks (after baseline visit 1)
Adverse events will be noted by the following: 1. \- Mild AE - No treatment needed 2. \- Moderate AE - Resolved with treatment 3. \- Severe AE - Inability to carry on normal activities, required professional medical attention 4. \- Life-threatening or disabling AE 5. \- Fatal AE
