Detailed Description
Cyclic vomiting syndrome (CVS) is an difficult to treat and debilitating functional gastrointestinal disorder. Majority of children and adults with CVS have concurrent severe abdominal pain and migraine-features, rendering them incapacitated during the vomiting cycle.
The vagus nerve carries signals of nausea, vomiting and pain between the brain and the gastrointestinal tract and is part of the autonomic nervous system. The autonomic nervous system appears to be in imbalance in patients with CVS during a vomiting cycle. By stimulating a branch of the vagus nerve in the outer ear, this study aims to improve symptoms and quality of life in both children and adults with CVS.
Subjects will be randomized to receive active vs sham (non-active) neurostimulation therapy for 5 days at the onset of a CVS cycle. They will then cross over to the other group (active vs sham) at the onset of the next CVS cycle. Subjects in a separate sub-study receive 6 weeks of active neurostimulation therapy (5 days/week). Pain, nausea, vomiting, anxiety, quality of life, potential side effects and overall symptom improvement will be monitored before and after therapy for the entire study.

Outcome Measures
Primary Outcome Measures
- Baxter Retching Faces Scale [From date of baseline assessment (therapy start date) through next 7 days for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
Daily nausea severity assessed by pictorial nausea faces scale 0-10 (0=no nausea; 10=worse possible nausea) with higher scores indicating worse outcomes (greater nausea).
Secondary Outcome Measures
- Numeric pain scale [From date of baseline assessment (therapy start date) through next 7 days for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
Daily pain severity assessed by numeric pain scale 0-10 (0=no pain; 10=worst possible pain) with higher scores indicating worse outcome (greater pain).
- Anxiety [From date of baseline assessment (therapy start date) and day 5 of therapy for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
State-Trait Anxiety Inventory for Children and Adults
- Health-Related Quality of Life [From date of baseline assessment (therapy start date) and day 5 of therapy for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
Patient Reported Outcomes Measurement Information Systems
- Disability in Children [From date of baseline assessment (therapy start date) and day 5 of therapy for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
Functional Disability Inventory
- Disability in Adults [From date of baseline assessment (therapy start date) and day 5 of therapy for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
Sheehan Disability Scale assessing disability and impairment on a scale 0-10 with higher scores indicating more disability. Three sub scales: 1) school/work, 2) social life and 3) family life are assessed (scale 0-10) with a total score reflecting the sum of the 3 subscales (total score range 0-30 with higher score indicating more disability).
- Global symptoms [From date of baseline assessment (therapy start date) and day 5 of therapy for each cycle of therapy. Also assessed at follow-up visit 3 months after end of therapy and further follow-up visits up to 12 months after end of therapy.]
Global symptom improvement scale
