🧍 Postural Balance and Center of Pressure: How the Body Stays Upright
Explore the biomechanics of quiet standing, from the inverted pendulum model and center of pressure sway to the vision, vestibular, and proprioceptive systems that keep the body balanced.
The simulation shows the body modeled as an inverted pendulum balanced over a base of support, with a real-time center of pressure trace responding to simulated sensory input and small perturbations.
🔬 What It Demonstrates
The simulation shows the body modeled as an inverted pendulum balanced over a base of support, with a real-time center of pressure trace responding to simulated sensory input and small perturbations.
🎮 How to Use
Adjust which sensory inputs are available (vision, vestibular, proprioception) and apply perturbations of varying size to see whether the body responds with an ankle strategy, a hip strategy, or a protective step.
💡 Did You Know?
Force plates used in real balance labs can detect center of pressure shifts smaller than a millimeter, which is how researchers can quantify subtle balance deficits long before a person notices any unsteadiness themselves.
