Wilke Spine Disc Pressure Model

The Wilke Spine Pressure models are eight models that compare intradiscal pressure measured between L4 and L5 discs in different postures.

For the comparison, all data is normalized (100 %) to the forces from ‘SpinePressureStanding.Main.any’ and ‘Relaxed Standing’ to show trend validity between the various postures.

Both papers refer to the same trial, but supplements each other with study information.
