TEA Synchronized With Natural Breathing for EPS

This arm will receive the experimental treatment for 4 weeks.

The AutoSTEA device is a device that detects the user's respiration wave and synchronizes each breath to deliver electrical stimulation at acupuncture points via skin surface electrodes. With this automated synchronization device, patients can inhale and exhale with an uninterrupted and normal respiration pace while receiving the TEA treatment, largely simplifying the treatment procedures, improving patients' compliance, and enhancing the effectiveness of the method.

This arm will first receive the sham treatment for 4 weeks.

The sham treatment is the same as the AutoSTEA device except that it doesn't synchronize with users breathing. It still does deliver the same electric shocks.

This questionnaire will be filled out daily, and it describes the physical dyspepsia symptoms experienced by the patient in the last 24 hours. It is done on a scale from 0-10, with 0 meaning they have not experienced a symptom at all, and 10 being they have severely experienced a symptom.

Assess how well a patient's dyspepsia symptoms respond to the treatment. This will be done using the Nepean Dyspepsia Index Questionnaire. One will be filled out weekly, where patients describe how much their dyspepsia symptoms have affected their daily lives. The scale for this will be 0-4, with 0 being no effect on their daily life and 4 being extreme effect on their daily lives.

Assess how easy the device is for patients to use in their home. This will be done using the usability questionnaire. This questionnaire will be filled out daily and the user will rate on a 0-5 scale how easy and comfortable the device was to use. 0 would signify the device being extremely difficult and extremely uncomfortable to use, while 5 would signify the device being extremely easy and extremely comfortable to use.

Assess any adverse effects the device may have when used by patients in their home. This will be done using the device safety questionnaire. The safety questionnaire is to be filled out weekly, with any adverse event that is experienced being reported. These adverse events (if applicable) will be rated in severity on a 0-5 scale, with 0 being no experienced adverse event and 5 being extremely severe (requiring medical attention).

Patients will keep a device-use log that is filled out daily. They will write how many sessions they use the device for and how long each session was.

The patient will undergo an EGG. The myoelectrical activity of the stomach will be measured by cycles per minute (CPM), which is the frequency of electrical slow waves generated by the smooth muscles of the stomach. A CPM of under 2.5 or above 3.75 will be considered abnormal.

Patients will undergo an ECG. This will measure their heart rate variability (HRV) by tracking the interval in milliseconds between each heartbeat. What is considered normal or abnormal will vary greatly depending on the patient.
