Clinical practice commonly attributes musculoskeletal pain to specific muscle weaknesses—weak cores, quadriceps, or glutes—leading to targeted strengthening protocols. However, this tissue-specific weakness model lacks robust scientific foundation, as pain rarely correlates directly with localized muscle deficits or structural abnormalities. The reductionist approach oversimplifies pain's complex neurobiological nature, where central sensitization, movement patterns, and psychosocial factors often matter more than isolated muscle strength. This paradigm shift has significant implications for rehabilitation approaches. Rather than pursuing targeted strengthening based on assumed weak links, evidence increasingly supports broader movement-based interventions that address pain through neuroplasticity, confidence building, and graded exposure. The weakness-focused model can inadvertently reinforce pain-related fear and movement avoidance by suggesting structural fragility. More effective approaches emphasize progressive loading, movement variability, and patient education about pain mechanisms. This represents a fundamental reconceptualization moving from mechanical fixes to biopsychosocial understanding, potentially improving outcomes for millions experiencing chronic musculoskeletal conditions by addressing root neurological and behavioral components rather than chasing anatomical red herrings.
