A sensor mat creates a visual record of pressure where the body meets a supporting surface. It can assess wheelchair cushions, mattresses, toilet seats, and other surfaces used for prolonged sitting or lying.
A clinician interprets computer-generated pressure images alongside a physical assessment. The image locates higher and lower readings; clinical examination connects those readings to the person’s body.
What are the limitations to the use of pressure mapping?
Position, equipment, and testing methods affect readings; mapping cannot assess every contributor to skin injury. Moisture, friction, age, and time spent sitting also influence skin health.
Experts value the technique, but direct evidence that it prevents pressure injuries after SCI remains limited. Much existing prevention research involves other populations, limiting conclusions specifically for SCI.
