Study of Enterra Programming with Nocturnal Cycling in Gastroparetics

The purpose of this research study is to evaluate if different Enterra® device programming methods active during sleeping hours can maintain gastroparesis-related symptom relief and quality of life measures. Participants in this study with existing Enterra® devices will be randomly assigned to one of three programming methods that will be active during sleep. Participants will answer daily questions about their gastroparesis symptoms on an application with their phone/tablet. Participants will answer quality of life questionnaires about their gastroparesis symptoms at study visits. Participants will be involved in the study for up to six months after treatment assignment. Programming parameters in the study are within currently approved labeling.
