Reactive Postural Adjustments | Strategies For Maintaining Balance

The video explains reactive postural adjustment strategies used to maintain balance during unexpected perturbations. It covers three main strategies: ankle, hip, and step. The ankle strategy is used for small perturbations, relying on ankle proprioceptors. The hip strategy is for large or fast perturbations with a narrow base of support, involving opposite movements of the head and hips. The step strategy involves taking a step to adjust the base of support in response to large perturbations.

Explain the difference between the hip strategy and the step strategy.

What happens to the head and hips during the hip strategy when a large perturbation occurs?

How does the base of support influence the choice of postural adjustment strategy?
