Abstract

Observing small changes (SCs) at specific sites is a new form of managing changes in position. We investigated SCs at specific sites considering interface pressure, contact area, body alignment and physical sensation in nine healthy female adults and evaluated SCs using the air mattress that was divided into six cells (A-F). Thirty-three SC combinations at one or several sites were evaluated. Pressure in the sacral region significantly decreased in 28 SC combinations compared with the supine position (p < 0.05), and the effect of pressure redistribution was greater when SCs were applied at several instead of a single site. The contact area at 17 of the 28 SC combinations significantly increased (p < 0.05). Among sites ranked based on interface pressure, body alignment and physical sensation, SCs at sites BCE, AE and BD were the most favorable. The common feature among these three combinations was that they involved tilting the buttock region and one other site. The findings suggested that SCs at the buttock region could reduce disruptions in alignment as well as the impact on physical sensation caused by the body sinking into the mattress and improve interface pressure redistribution via increased contact area with the mattress.
