Outcomes

Primary Outcomes

Peak Sacral Pressure

Peak sacral pressure is defined as the highest pressure within a 9-10 cm squared area under the coccyx. The area under coccyx was identified prior to each condition tested using the pressure mapping system. Presure was recorded continuously for 15 minutes. Because the mattresses tested were advertised as 'cycling' pressure, with the cycles set to 5 minutes, the average of minutes 1-3 and 6-8 were used for analysis. These periods represent different phases of the 'cycling' where sacral pressure would conceivably differ.

Time frame: minutes 1-3 and minutes 6-8
