The purpose of this study was to investigate the effects of support surface mattresses of different bedbackrestlifting angles on interface pressures around sacral regions. Ten healthy people (average age 21± 2.4, 4males) participated in this study. The interface pressure around sacral region was measured infour types of mattresses with 0, 30, 45 and 70 degrees of bed-backrest lifting angle respectively: astandard mattress, an iris urethane mattress, an air mattress, and a maxi float mattress. The averages ofinterface pressures, maximum interface pressures and area supporting surfaces were measured by theuse of a pressure-sensitive sheet. Those averages with the different bed-backrest lifting angles and thefour types of mattresses were statistically examined by ANOVA. The three types of support surfacemattresses were compared with the standard mattress. The average values of interface pressures ofsupporting surface were significantly lower than those of the standard mattress (p < 0.05), and also thearea of supporting surface of support surface mattresses were significantly wider than those of thestandard mattress (p < 0.05). Maximum interface pressures were approximate 100mmHg in all of themattresses with bed-backrest 45 and 70 degrees up. The results show that the value of interfacepressure increases as the degree of head up rises in all of the mattresses. This suggests that interfacepressure should be considered while the bed-backrest is lifted up.
