Phramongkutklao Hospital.

Objectives:
To compare maximal interface pressure between rubber mattress
and air dynamic mattress in patient with ambulation problem.

Study design: Cross sectional study.

Subjects:
Participant with ambulation problem, need personal assistance

or assistive device.

Methods:
Participant lay down on the mattress in supine position in
5minutes. Pressure mapping measure maximal interface pressure (mmHg),
between patient and mattress, upper body and lower body part. Maximal

interface pressure is compared in patient with ambulation problem
with/without risk for pressure ulcer.

Results:
Compared maximal interface pressure with rubber and air
mattress were not significant in upper body (P-value= 0.404) and lower

body (P-value= 0.162). In subgroup analysis, participants with risk of
pressure, were not significant in upper body (P-value= 0.596) and lower
body (P-value= 0.138). In participants without risk of pressure ulcer were

not significant in upper body (P-value= 0.507) and lower body (P-value=
0.949).

Conclusion:
Rubber mattress has no significant to reducing interface
pressure in 5 minutes compared with air mattress in patients with

ambulation problem.
