\n Epistemic note<\/strong> \u2014 This article presents pathophysiological mechanisms drawn from scientific literature in neuroscience and biomechanics. It does not constitute medical advice, does not establish a diagnosis, and does not formulate therapeutic recommendations. The mechanisms described are presented for educational purposes; their clinical application is a matter for qualified healthcare professionals.\n<\/div>\n\n\n\n\n\n\n

Summary<\/strong> \u2014 Chronic pain is not always a sign of tissue damage. It can result from a nervous system that has become hypersensitive: it amplifies signals, “learns” pain, and maintains an alert state even in the absence of any real threat. This mechanism \u2014 central sensitization \u2014 is biological, measurable, and above all, reversible. This article explains how it develops, what role fascia and mechanical constraints play, and why reintroducing movement variability is the key to recalibrating the system.<\/p>\n<\/section>\n\n\n\n\n\n\n
