Pressure Relief
A deliberate, scheduled shift in body weight performed by or for a seated or recumbent person to reduce sustained pressure on bony prominences and prevent tissue breakdown.
Full Definition
Pressure relief is a foundational concept in rehab technology seating and positioning. It refers both to the clinical behaviour (a timed weight shift) and to design features engineered into seating systems to facilitate or automate that shift—such as tilt-in-space mechanisms or elevating seat functions. Editors encounter the term in seating assessment reports, power wheelchair prescriptions, and funding justification letters. It is distinct from 'pressure redistribution,' which describes how a cushion material disperses load across a surface over time. Conflating these terms in clinical documentation can misrepresent the intervention being funded and affect reimbursement.
Usage
Usage note: Distinguish carefully from 'pressure redistribution' (a cushion property) and 'pressure mapping' (an assessment technique) when editing clinical or funding documents.
