Ten healthy people (average age 21 ± 2.4, 4males) participated in this study. The interface pressure around sacral region was measured in four types of mattresses with 0, 30, 45 and 70 degrees of bed-backrest lifting angle respectively: a standard mattress, an iris urethane mattress, an air mattress, and a maxi float mattress. The averages of interface pressures, maximum interface pressures and area supporting surfaces were measured by the use of a pressure-sensitive sheet. Those averages with the different bed-backrest lifting angles and the four types of mattresses were statistically examined by ANOVA. The three types of support surface mattresses were compared with the standard mattress. The average values of interface pressures of supporting surface were significantly lower than those of the standard mattress (p < 0.05), and also the area of supporting surface of support surface mattresses were significantly wider than those of the standard mattress (p < 0.05). Maximum interface pressures were approximate 100mmHg in all of the mattresses with bed-backrest 45 and 70 degrees up. The results show that the value of interface pressure increases as the degree of head up rises in all of the mattresses. This suggests that interface pressure should be considered while the bed-backrest is lifted up.}, pages = {143--149}, title = {ギャッジアップ角度と体圧分散との関係}, volume = {7}, year = {1999} }
