Analysis of Potential Risk Factors in Sensory-related Static Supine Posture with or without Wedge for Healthy Science Research

Objective The purpose of this study was to analyze body pressure-related sensory changes in males and females in a static supine posture with or without wedge for healthy science research. Methods The Body Pressure Measurement System was used to analyze body pressure, and body pressure sensors were attached to mattresses beneath the subjects. Before the supine posture with wedge was adopted, pain score tools were used to evaluate the level of pain at 1, 5, 10, and 15 min, and in total for specific parts of the body. Results In analysis of digitized images, head pressure intensity and shoulder pressure intensity were significantly higher than the pressure intensity of other body parts. In terms of head pressure intensity, the static supine group with wedge was significantly higher than the non-wedge group. The total pain score values for each body part in the supine group were higher than in the supine with wedge group. In particular, the value for pelvis pain in the supine group was significantly higher than in the supine with wedge group. All values were significantly increased after the supine posture with wedge was adopted. Conclusion These results suggest that postural changes and properties that change in a time-dependent manner need to be carefully considered when applying pain rehabilitation.
