PhronesisWe apply the Displacement Framework to Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS), formalizing it as W_ME — a post-infectious energy wrong attractor characterized by dysfunctional cellular energy metabolism in which physical exertion deepens rather than resolves the attractor through post-exertional malaise (PEM). The energy ground state S⁰_energy is defined across six dimensions: normal oxidative phosphorylation, proportionate ATP dynamics, PDH enzyme activity, proportionate exertion-recovery, calibrated autonomic regulation, and refreshing sleep.
W_ME is triggered by infectious or immune insult and is maintained by PDH suppression, IDO metabolic trap, mitochondrial membrane potential abnormalities, NK cell dysfunction, GPCR autoantibodies, and neuroinflammation. The exercise intolerance paradox is the pathognomic feature: graded exercise therapy (GET), effective for deconditioning, deepens W_ME through repeated PEM induction — formalized as GET increasing Φ rather than reducing it.
PEM is formally modeled with D(ξ_PEM) incorporating excess exertion and PEM history terms; two-day CPET data showing 10-22% VO₂max decrement on day 2 provides objective measurement of the energy landscape collapse. Nine formal propositions cover: S⁰_energy definition (P1), W_ME post-infectious formation (P2), PEM as landscape collapse event (P3), the exercise paradox and PACE trial failures (P4), energy envelope pacing as the evidence-based return path with D(ξ_activity) < D(ξ_threshold) (P5), cellular energy mechanisms (P6), autonomic dysfunction and POTS (P7), Long COVID as ME/CFS pandemic amplification (P8), and the treatment absence as systematic medical failure (P9).
The paper formally distinguishes ME/CFS from deconditioning and depression-related fatigue.
