How is a Pressure Mapping Tool Used to Select the Right Seat Cushion?
A pressure mapping tool is used as a data-driven diagnostic aid during a seating evaluation to ensure a cushion is perfectly matched to an individual’s unique anatomy. The process follows a specific clinical workflow:
- Visualizing Pressure Distribution: A thin, flexible sensor mat is placed between the user and the cushion. It sends real-time data to a computer, creating a color-coded map where warmer colors (red/orange) indicate high-pressure "hot spots" and cooler colors (blue/green) show even weight distribution.
- Analyzing Key Metrics: Certified Assistive Technology Professionals (ATPs) look at specific data points, such as the Peak Pressure Index (PPI) to identify injury risks, and the Contact Area to ensure weight is spread across the largest possible surface.
- Comparing Cushion Materials: The tool allows clinicians to objectively test how different materials—such as air, foam, gel, or hybrid designs—manage pressure for the user. It reveals how well a cushion contours to the body to prevent skin breakdown.
- Static and Dynamic Testing: Mapping is used to evaluate pressure not just while sitting still, but also during movement, such as reaching or reclining. This ensures the selected cushion provides protection throughout daily activities.
- Refining the Fit: Clinicians use the map to make iterative adjustments, such as changing the seat dump or back angle, to see an immediate reduction in pressure before finalizing the custom seating prescription.
