Pressure Injury Prevention Through Correct Seating
Pressure injuries are one of the most serious and most preventable complications faced by people who spend significant time in a wheelchair. Correct seating and positioning is one of the most effective tools available for reducing this risk and understanding how it works helps explain why seating prescription is such a clinically significant process.
How Pressure Injuries Develop
Pressure injuries occur when sustained pressure, often combined with shear or friction, reduces blood flow to the skin and underlying tissue over bony areas such as the sacrum, hips, heels and shoulder blades. Risk increases with reduced mobility, reduced sensation, poor nutrition, moisture and time spent in a single position all common factors for people with significant physical disability.
How Seating Reduces Risk
A well-prescribed seating system reduces pressure injury risk in several ways:
Pressure redistribution — cushions and backrests designed to spread load across a larger surface area, rather than concentrating pressure over bony prominences
Postural support — correct alignment reduces shear forces caused by sliding or slumping
Tilt-in-space — allows periodic pressure relief without requiring a full transfer out of the chair
Correctly fitted components — footplates, armrests and lateral supports that keep the body appropriately positioned rather than compensating through poor posture
The Role of Repositioning Schedules
Even the best seating system can't eliminate pressure risk entirely regular repositioning remains essential. A repositioning schedule, developed as part of a seating assessment, specifies how often and how a client should shift position, whether independently or with support. For clients who can't reposition themselves, this relies on consistent implementation by carers and support workers.
Why Implementation Matters as Much as Equipment
Prescribing the right seating system is only half of the picture the benefits are only realised if the equipment is used correctly and consistently. This is why seating assessments typically include education for carers and support teams, covering correct setup, positioning technique and what warning signs should prompt an urgent review.
Early Warning Signs to Watch For
Skin redness that doesn't fade within 30 minutes of pressure relief, new areas of discomfort or visible changes in skin condition all warrant prompt clinical attention. Left unaddressed, early skin changes can progress rapidly, particularly in clients with reduced sensation who may not be able to reliably report discomfort.
A Preventive, Not Reactive, Approach
Pressure injury prevention works best as an ongoing, proactive process regular seating review, consistent repositioning and prompt attention to early warning signs rather than a response to an injury that has already developed. Established pressure injuries can take months to heal and significantly affect quality of life, making prevention by far the better path.
