This project includes a 4-week randomized trial comparing pre-meal vagal nerve stimulation (taVNS) to pre-meal sham stimulation. The aims will assess if taVNS results in greater satisfaction, greater calorie consumption, less self-reported fullness, decrease in eating disorder symptoms, and less anxiety than sham stimulation.
The purpose of this research study is to determine the safety and ability of a device that will stimulate the vagus nerve (taVNS), in 30 adolescents ages 14-17. This project will explore if stimulation has any effect on eating behaviors in individuals with eating disorders, such as Anorexia Nervosa. Study measurements include eating behavior and other measures of behavior. These measurements will take place before and in response to the nerve stimulation during the course of a 4-week randomized trial. Participants are assigned to one of two conditions: 1) Vagal Nerve Stimulation (n=20; this g…
Inclusion Criteria: * Ages 14-22 * Engaged in standardized refeeding in the EWDP during the intervention (may include individuals with anorexia nervosa or avoidant/restrictive food intake disorder) * Needing to gain at least 8 lbs during the refeeding period * English-speaking Exclusion Criteria: * Pregnancy * GI disturbance or diagnosis (Crohn's disease, diverticulitis, irritable bowel syndrome, gastric bezoar, or suspected or known GI obstruction) * GI surgery in the last 3 months * Implanted or portable electro-mechanical device such as a pacemaker, defibrillator, or infusion pump * Alle…
Participants will receive vagal nerve stimulation approximately 3 days a week for 30 minutes over the course of 4 weeks while they are attending treatment for Anorexia Nervosa in the Eating and Weight Disorder Intensive Program.
