Four Core Principles for Applying the Biopsychosocial Model

Working from the definition of pain as a distressing experience with sensory, emotional, cognitive and social components, the speaker argues that sensitivity is a less threatening and more accurate word than tissue damage, since language can create nocebo effects. Phantom limb pain and persistent pain after knee replacement show pain is not simply a tissue input. The and, not or principle replaces single cause thinking. Shoulder pain may involve scapular dyskinesis, but also static postures, training volume, history and beliefs; research suggests guessing the painful shoulder from dyskinesis is close to a coin toss. The same applies to flat feet and knee pain. Relevance versus prevalence asks whether findings such as anterior pelvic tilt, joint space loss on imaging or bulging discs matter for the person in front of you. Clinicians are framed as facilitators, not fixers. The last principle uses the cup analogy: sleep, stress, fear, beliefs and tissue health are all loads, and people differ in how they handle them.
