Healthcare professionals are generally well aware of the terms pressure, shear and friction in relation to pressure ulcers. They may be less familiar with use of microclimate when discussing pressure ulcer aetiology. Whilst most will have a basic understanding of some or all of these terms, there is a tendency for eyes to glaze over when terms like perpendicular force or tangential force are used. A major strength of the consensus document is that it explains the science behind pressure, shear, friction and microclimate and then applies it to practical issues.�
