Heart Rate Variability and Inflammatory Bowel Disease

"At all 4 assessment points (T1-T4), HRV will be measured using the ECG module of the mobile MindWare system at a sampling rate of 500 Hz, and a Skin Conductance Response (SCR) will be collected at a sampling rate of 10 Hz using eSense for iPad. Electrodes to assess SCR and HRV will be attached to patients during an \~10-minute period.~A 5-minute initial baseline assessment will occur first followed by three 5-minute stress trials.~Stress tasks will be audio recorded to measure study fidelity, and participants will be asked to rate their subjective level of stress with each trial. At all assessment points (T1-T4), participants will be provided with stool collection kits to collect a stool sample within 3 days of the laboratory psychophysiological assessment.~At all assessment points (T1-T4), a blood draw of approximately 3 ml of blood will be collected."
