Abstract
Endoscopists performing fluoroscopy procedures often suffer from musculoskeletal disorders (MSDs) due to persistent static muscle contraction and the load imposed by radiation personal protective equipment. We devised the "practical load-on-the-shoulders releasing technique" (PoRT), integrated it within the work-rest schedule, and investigated its ability to reduce muscular discomfort. The results showed that PoRT lowered discomfort, including by maintaining the head angle closer to the neutral position and keeping the trunk in a stable state, which together resulted in an ideal posture. As a simple, no-cost intervention based on an ergonomic approach, PoRT may contribute to reducing MSDs.
