A body–surface–pathway–point cognitive framework for human functional systems: translating the material–space–flow meta-model into an operational clinical navigation architecture

Building on the “Material-Space-Flow” (MSF) meta-model, this paper proposes the “Body-Surface-Pathway-Point” (BSPP) system theory as a structured cognitive navigation framework for understanding and intervening in complex human systems. The framework defines functional units (Body), interaction interfaces (Surface), conduction pathways (Pathway), and regulatory nodes (Point), and specifies synergistic and destabilizing mechanisms among these elements. Within this model, systemic functional states are attributed to the maintenance or breakdown of the spatiotemporal order of pressure gradients. The central contribution of the BSPP framework is its generativity: it provides a universal cognitive grammar that shifts clinical reasoning from static lesion localization to dynamic navigation and repair of dysfunctional relational patterns. The overarching aim is to establish a complete methodology that links theory to practice for navigating and restoring the spatiotemporal order of systemic pressure gradients, proposed here as the physical basis of systemic function.
