The coefficient of friction of wheelchair seats as a risk assessment for potential pressure ulcers

Short description

Pressure ulcers in wheelchair users are caused by shear stress. We investigated the kinetic coefficient of friction (COF) of 5 wheelchair seats. The lowest COF measured (0.35-0.4) was still too high. We recommend a very low COF surface combined with a concave seat to reduce the ulcer risk.
