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.
