Category 1: Control Strategies for Balance

What is Steady State Postural Control?

A

The ability to control the location of the body’s COM within the area defined by the BOS under predictable, quasi-static conditions.
- This includes the ability to adapt motor behavior to meet the demands of different task and environmental conditions

Category 1: Control Strategies for Balance

What is Anticipatory Postural Control?

A

The ability to generate postural adjustments prior to the onset of and during voluntary movement for the purpose of either countering an upcoming postural disturbance due to voluntary movement or realigning the body’s COM prior to changing the BOS.
- This includes the ability to adapt motor behavior to meet the demands of different task and enviornmental conditions

What is Reactive Postural Control?

A

The ability to respond to sensory input that signals a need for a response to ensure successful maintenace of postural control. The need for response is unanticipated but may be generated externally (pertubation originating external to body) or secondary to an internally generated movement.
- This includes the ability to adapt motor behavior to meet the demands of different task and environmental conditions
