Development of a statistical model for predicting seat pressure felt level in simulated condition based on direct and anthropometric measurement.
Nor Kamaliana Khamis, Baba Md Deros
PMID 29950761WHAT IT FOUND
In 11 adults seated in a driving simulator, felt pressure was highest at the buttocks, not the thighs.
Seat pressure and a body measurement were linked to reported pressure.
Key findings
01Reported pressure felt averaged 6.52 at the buttocks and 2.00 at the thighs on a 0 to 10 scale.
02Measured pressure was 2.88 psi at the buttocks and 0.83 psi at the thighs.
03Buttock-popliteal length was related to pressure distribution at the buttocks, and both were used to predict reported pressure felt.

What it does not show
Only 11 subjects were studied, so the model may not hold for other drivers. The participants were staff and student drivers, not patients, so the study does not address a clinical group. The work was done in a driving simulator, not a real vehicle, so findings may not transfer to everyday driving. The measured outcomes were pressure felt and pressure distribution, not pain, function, injury, or treatment response.
Declared interests
This research was under GUP-2017–094 funding. The authors declared no conflict of interest.
The easy way to misread this
Do not use this model to predict patient comfort, pain, or seating safety. It was developed from 11 licensed drivers in a simulator, and it measured felt pressure and pressure distribution.
