Conditions

Pain

Summary

Chronic abdominal pain is a common disorder that can have significant impact on the lives of patients. Treatment options include medication which can have limited effectiveness, be associated with side effects and may lead to tolerance and dependency. Spinal cord stimulation (SCS) is a minimally invasive, therapeutic option for managing chronic abdominal pain. This involves implanting a device that delivers mild electrical signals to the spinal cord to reduce pain. Conventional SCS has been shown to improve abdominal pain caused by different disorders, but it causes feelings of unpleasant tingling in the tummy area. This feasibility study aims to explore relief from chronic abdominal pain symptoms when using a device that does not cause uncomfortable tingling feelings in the tummy area.
