Sensor-Based Ergonomics - Developing a System to Measure Transitional Phenomena during Repositioning

[1. Introduction] People who are in lying positions require 'body repositioning'. In nursing care, 'body repositioning' is necessary to prevent pressure ulcers, joint contractures, nerve paralysis, and lower lung injury. Nursing skills for 'body repositioning' are acquired from knowledge of body mechanics and learning through exercises. Articles describing the impact of repositioning on patients include hemodynamic changes, ventilation changes, and relationships between frequency of positional changes and reduced risk of pressure ulcers. However, techniques of repositioning and pressure transitions a patient undergoes during repositioning have not been evaluated.
