Operational Probe and Falsification Framework for Human Restoration Theory

Abstract Human Restoration Theory proposes that skeletal load-bearing efficiency under gravity functions as a systemic regulatory variable. If this claim is to be scientifically meaningful, it must be exposed to direct empirical pressure. This paper presents a practical observational probe centered on the sit-to-stand transition as a reproducible window into early recruitment strategy under gravitational demand. The distinction examined is not strength or performance, but organizational strategy: whether standing emerges primarily through structural load transmission or through compensatory muscular holding. Two observable modes are proposed: doing and allowing. Doing is characterized by deliberate initiation, visible muscular effort, breath bracing, cervical pulling, and co-contraction-driven stabilization. Allowing is characterized by minimal initiative, preserved ground contact, respiratory continuity, and the emergence of standing as a consequence of available structural transmission rather than imposed effort. The purpose of the probe is not diagnostic classification, but falsifiability. If meaningful alteration of gravitational encounter conditions fails to produce measurable changes in early recruitment patterns, anticipatory postural adjustments, co-contraction indices, and functional stiffness without destabilization, the central explanatory premise of the framework weakens substantially. The model is therefore presented not as a protected theory, but as a testable claim.
