What Data does a Therapist Look for During a Pressure Mapping Session?
During a wheelchair pressure mapping evaluation, a therapist or certified Assistive Technology Professional (ATP) analyzes several critical metrics to identify skin injury risks and optimize seating comfort. The data points they look for include:
- Peak Pressure Index (PPI): This identifies the single highest-pressure spot in the seated area, serving as a primary red flag for potential tissue damage.
- Pressure Gradient: This measures how quickly pressure shifts between high and low zones. Steep transitions often indicate that a cushion is not contouring properly to the user’s body.
- Contact Area: This measures the total surface area supporting the user’s weight. Generally, a larger contact area helps spread pressure more evenly, reducing the risk of injury.
- Symmetry Data: Therapists compare pressure distribution between the left and right sides to identify postural asymmetries caused by muscle weakness or conditions like scoliosis.
- Visual Color Maps: The software generates a color-coded map where warmer colors (red and orange) signal high-pressure zones, often found around bony prominences like the ischial tuberosities. Cooler colors (blue and green) indicate areas where weight is well-distributed.
- Dynamic Movement Data: Beyond static sitting, therapists observe how pressure distribution changes in real time as the user reaches, leans, or operates the wheelchair joystick.
