Examining the Validity of An Endoscopist-patient Co-participative Virtual Reality Method (EPC-VR) in Pain Relief during Colonoscopy.

To relieve perceived pain in patients undergoing colonoscopy, we developed an endoscopist-patient co-participative VR tool (EPC-VR) based on A Neurocognitive Model of Attention to Pain. It allows the patient to play a VR game actively and supports the endoscopist in triggering a distraction mechanism to divert the patient's attention away from the medical procedure. We performed a comparative clinical study with 40 patients.
