Analysis of the body pressure-related sensory changes in the static supine position for healthy science research: a randomized controlled pilot trial

Abstract

The aim of this study was to analyze body pressurerelated sensory changes after being in a static supine position to the head, shoulder, right and left arms, low back, pelvic girdle, and right and left legs. To analyze body pressure, a Body Pressure Measurement System was used. Body pressure sensors were attached to existing mattresses and pressure was monitored beneath the ten subjects (five male and five female). The level of pain was evaluated using the pain scale before, at 1, 5, 10, and 15 min, and in total of the head, shoulder, right and left arms, low back, pelvic girdle, and right and left legs after being in the static supine position. Head pressure intensity was significantly higher than other body part measures, and the head had the highest pain score, almost showing a similar tendency. However, the low back was not too high in body intensity, while it had the second highest total pain score. As well, the low back and pelvic girdle showed a significant difference between the pain scores of males and females. The pain appeared after 10 min on all measuring parts. As well, as time progressed, the level of pain became more increased. These results suggest that when performing physical therapy and healthy science research, the properties of time, posture, and gender need to be carefully considered.
