Introduction and Hypothesis <p>Current research on pelvic floor disorders is constrained by fragmented disciplinary approaches, static anatomical views, and insufficient attention to biomechanical balance. This paper is aimed at constructing a novel theoretical framework for pelvic floor stress dysfunction disorders (PFSDs) by integrating philosophical and scientific methodologies.</p> Methods <p>Using First Principles thinking, we redefine PFSD as a disruption of dynamic biomechanical equilibrium centered on the concept of “force.” Inductive and deductive reasoning are applied to critically evaluate existing theories (e.g., Three-Compartment, Hammock), while verification and falsification principles are employed to expose logical inconsistencies between etiology and treatment.</p> Results <p>The analysis reveals fundamental limitations in current theories, which fail to account for the dynamic and integrated nature of pelvic floor function. We propose physiological biomechanical reconstruction—rather than symptom-based repair—as the core therapeutic objective. Boundary-breaking innovation promotes a holistic understanding of pelvic floor synergy across disciplines.</p> Conclusions <p>This philosophically grounded framework shifts the focus from static anatomy to dynamic biomechanical balance, offering a logical basis for evidence-based PFSD management. It supports a transition from empirical to mechanism-driven approaches in both research and clinical practice.</p>
