Video-Based Versus Numerical Pain Assessment in Postoperative Patients: A Pilot Study

"The Numerical Rating Scale (NRS) is a standardized, self-reported pain assessment tool in which patients are asked to rate their pain intensity on a scale from 0 to 10.~0 represents no pain~10 represents the worst pain imaginable"

"This novel pain assessment method involves showing postoperative patients a set of pre-recorded video scenarios that visually represent different levels of pain intensity. The videos are 8 seconds long and were created using AI-generated scripts and VEO-3 software. Each scenario corresponds to a specific Numerical Rating Scale (NRS) range (1-2, 3-4, 5-6, 7-8, 9-10) and is portrayed by actors matched to the patient's age group and gender (18-44, 45-65, \>65 years; male and female versions available).~Participants are asked to watch the full video set and select the one that best represents their current postoperative pain experience. This intervention is designed to offer a visual and contextual method of pain expression, particularly beneficial for patients who have difficulty understanding or using abstract numerical scales."
