Pressure Study
Author: Broda Seating
Published: 19 May 2009
The following outlines the results of a pressure study performed with a test subject on various surfaces including Broda's Comfort Tension Seating™. Testing was performed with a Tekscan Model 5330- 32 x 32 Element Sensory Array.
The sensor processing software calculated the following information:
- Peak Pressure (mmHg)
- Highest reading recorded at one or more sensors
- Average Contact Pressure (mmHg)
- Mathematical average of all non-zero elements
Subject: Male, 5'6", 200 lbs.
Each test chair had armrests removed. Test subject's feet remained flat on
the floor or footrest (with knees at an approx. 90° angle) to maintain a
consistent body position throughout each test for accuracy purposes.(except
when tested in the tilt and recline position in the Broda 785)
Surfaces and Results
Peak and average pressures are average after one hour of sitting.
Wheelchair sling with no additional padding.
