From: The effect of a trunk release maneuver on Peak Pressure Index, trunk displacement and perceived discomfort in older adults seated in a high Fowler’s position: a randomized controlled trial

Peak Pressure Index (PPI)

Before trunk release

After trunk release

Range

64 to 98.75 mmHg

39.5 to 59 mmHg

Median

85.3 mmHg

52.3 mmHg

  1. *These results are from a preliminary pressure mapping study that explored the influence of bed linen layers on interface pressure. High pressure over the sacral-coccygeal area was recorded when the person was moved into high Fowler’s position. The procedure was repeated 15 times with different bed linen layers.
