Brief Summary
Abdominal pain is a central symptom of Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS). IBD is an autoimmune disease characterized by inflammation of the gastrointestinal tract. IBS does not have clear biomarkers and is diagnosed based on symptom reports. The aim of this study is to explore biopsychosocial factors which may perpetuate and/or increase the severity of pain in these conditions. The main focus will be on the role of top-down brain processes in the experience of abdominal pain.

Outcome Measures
Primary Outcomes (2)
Efficiency of inhibitory pain modulation, comparing patients with IBS or quiescent IBD
Measured with Conditioned Pain Modulation test. Two inflatable pressure cuffs are secured around the caffs of subjects and then inflated. Pressure pain detection threshold (PDT) and pressure pain tolerance (PTT) are assessed on a subject's dominant leg. PDT is the first sensation of pain and PTT is defined as the point a subject no longer want the cuff to inflate. A VAS device allows participants to report their pain levels by moving a sliding button along a continuous line between two endpoints (0=no pain to 10=worst pain imaginable). After a second baseline measure on the non-dominant leg CPM is assessed: the cuff on the non-dominant leg is inflated to 70% of the subject's PTT, then after 15 seconds the cuff on the dominant leg is inflated. If pain modulation is achieved, the subject will show increased threshold and tolerance levels during CPM. The CPM-effect is defined as the difference between baseline and conditioning measurements of both PDT and PTT.

Contribution of socio-demographic, clinical and psychosocial factors to the efficiency of inhibitory pain modulation
Measured with a range of questionnaires, i.e.: Brief Pain Inventory Short Form (BPI), painDETECT questionnaire, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Visceral Sensitivity Index, Pain Catastrophising Scale, Cognitive and Behavioural Response to Symptoms Questionnaire, Pain Self Efficacy Questionnaire, Chronic Pain Acceptance Questionnaire-8, and Mental Health Continuum Short-Form

You may not qualify if:
- Major abdominal surgery in the last 6 months, or 3 or more previous major abdominal surgeries
- Pregnancy or childbirth in the last 6 months
- Any other diagnosed medical condition that may explain abdominal pain, including but not limited to known gynaecological conditions such as endometriosis and known post-surgical adhesions
- Any diagnosed co-morbid medical conditions associated with known neuropathy, such as diabetic neuropathy, renal neuropathy, multiple sclerosis
- Use of opioids in the last week
- Use of anti-depressants used as pain medication in the last month
