Using Pressure Mapping to Compare the Effect of Various Positioning

IRB Protocol Number STU00207594


Katherine Earnest


The purpose of this study is to use pressure mapping to compare effectiveness of various bed positioning aids in relieving pressure over bony areas of the body. Available information regading the effectiveness of bed positioning aids often uses data obtained using only non-disabled individuals. We hope to compare results from individuals with a spinal cord injury to those without an injury, using 4 different types of bed positioning aids. In addition to indicating if one type of positioning aid is more effective than another, this will help us determine if pressure mapping results obtained with non-disabled individuals can be applied to individuals with SCI or not. We hope this will provide information that will be useful to institutions and individuals when selecting bed positioning aids.
