Using inertial sensors for the generation of REBA and RULA reports in functional colonoscopy simulations
研究用惯性传感器自动收集结肠镜医生的动作数据，生成REBA和RULA报告来评估人体工学风险，发现新手风险更高，但主观问卷结果不一致。
Suboptimal ergonomics during colonoscopy procedures can lead to physical discomfort, fatigue and musculoskeletal conditions for the endoscopist. Measurement of possible risks is usually done using subjective ergonomic reports or involving trained observers who follow methods such as RULA and REBA. This paper introduces the use of IMUs for gathering motion data from colonoscopy practitioners and generating RULA and REBA reports automatically. Eight endoscopists performed two simulated functional colonoscopy procedures while wearing an inertial-magnetic motion tracker suit, the MTw Awinda by Xsens. The procedure was recorded while IMUs tracking data was captured and processed by the Xsens MotionCloud for automatic REBA and RULA report generation. Physicians also answered a NASA-TLX questionnaire to subjectively measure comfort and workload. Automatic REBA and RULA reports show higher ergonomic risk for novices, while subjective questionnaire results mismatch. The experiment indicates the usability of the system for automatic RULA and REBA generation.
