Summary

Older adults with a disability tend to spend greater periods of time in bed each day and often over a mealtime. To make it safe for them to eat in bed, the patient is placed in a high Fowler's position. This means that the head and the foot of the bed are raised to sit the person up.

Sitting up in bed increases pressure over the buttocks which can lead to the development of a pressure ulcer. The purpose of this study is to evaluate the impact of the positional change called "the trunk release" on pressure over the buttocks, on breathing and on comfort.

Primary Hypothesis - Performing the trunk release with an older adult population at low risk for pressure ulcer will result in a 5mmHg decrease in the peak pressure index over the sacral-coccygeal area as measured by the peak pressure index using a Force Sensitive Applications (FSA) Pressure Mapping System.

Secondary Hypotheses - Performing the trunk release with an older adult population at low risk for pressure ulcer will result in:

* Improved ventilation as measured by a 0.5 liter increase in slow vital capacity.
* Greater comfort as measured by a two point change on a horizontal numeric scale with word anchors combined with the Wong-Baker faces scale (Appendix D).
* A four-centimetre displacement of the trunk as it extends up towards the head of the bed.

PROCEDURE

The Big Squeeze

Trunk release as per MSIP protocol. Standing at the foot of the bed, facing the subject, Experimenter A grasps both ends of the flat sheet to pull the trunk forward and away from the mattress surface. As the trunk release procedure is performed, Experimenter A checks to verify that the laser beam shines through to the opposite wall to confirm that the shoulders have cleared the mattress.
