Pain Detection Through Automated Video Analysis

Before the videotaping, patients will be asked on their baseline pain scores. Their face and body pose from a frontal view will be videotaped via a mobile phone with no internet access. The collected videos will be further processed to extract key points, which will be the primary input for modelling algorithms and will further ensure anonymity of the patients in the video sequences.

"Patients will be asked to fill in 1-2 questionnaires before surgery/procedure/consultation (Hospital Anxiety and Depression Scale (HADS) and/or EQ-5D-3L). After surgery/procedure/consultation, patients will be again asked to fill in HADS questionnaire (optional).~For pediatrics patient, only Child Pain Anxiety Symptoms Scale (CPASS) will be administered before the surgery."

A medical grade wearable device, Empatica E4 wristband, will be used in phase 3 for pediatrics patients to monitor real-time physiological data on heart rate and body temperature.
