The millisecond negotiation with gravity

The Millisecond Negotiation With Gravity: How Your Body Stays Upright Every step you take is a controlled fall — and your nervous system has approximately 250 milliseconds to prevent it from becoming a real one. In this episode, Dr. Christophe Delong explores the extraordinary real-time computation that allows the human body to negotiate with gravity thousands of times per day. Balance is not passive. It is an active, neurologically complex process involving the vestibular system, proprioceptive input, visual processing, cerebellar integration, and anticipatory motor commands. When any part of this system fails — through aging, injury, or neurological disease — the risk of falls rises dramatically. This episode is essential for physiotherapists, neurologists, geriatricians, and anyone working in fall prevention, rehabilitation, or movement science. KEY TALKING POINTS 🔹 The three pillars of balance: vestibular, proprioceptive, and visual — and what happens when one fails 🔹 Cerebellar integration and the 250ms window: how the brain predicts and corrects postural sway 🔹 Anticipatory postural adjustments (APAs): the movement your body makes before you consciously move 🔹 Clinical assessment of balance and fall risk: from force plates to functional movement screens 🔹 Evidence-based rehabilitation protocols to restore postural control after injury, stroke, or aging ABOUT DR. CHRISTOPHE DELONG Dr. Christophe Delong is a French physician specializing in Physical Medicine & Rehabilitation (PM&R), Sports Traumatology, and Medical Podiatry. A former Intern and former Head of Department at the Assistance Publique - Hôpitaux de Paris (AP-HP), he combines decades of clinical expertise with cutting-edge research in movement science, rehabilitation, and artificial intelligence applied to medicine. He is the founder of Kinexa, a pioneering platform dedicated to AI-powered movement health and professional training for physiotherapists and healthcare professionals.
