Expert Guides

The scientific, anatomical, and biomechanical foundations of the Blue Portance Knowledge Base

The Expert Guides follow a progression: understanding pain, explaining how living systems function dynamically, studying the structures that allow stresses, fluids, and information to circulate, and then showing how prolonged sitting can impede these circulations. They form the in-depth foundation to which the Frequently Asked Questions, Lived Experiences, and Case Studies refer.

From Adaptive Potential to Its Assessment in the Sitting Position

Adaptive potential is a property of living systems. A seat does not create it: depending on its architecture, it can preserve the possibilities for its expression or constrain them.

SBNFA™ — Systemic Biological Neuro-fascial Adaptive Framework applies this principle to the specific situation of sitting. Its functional framework, structured into 7 functions and 19 state variables, makes it possible to describe and compare what different seating architectures enable or limit.
