Q

What is functional Recovery?

A

Improved function following injury

Doesn’t distinguish between movement strategies and or underlying processes used for function

Q

What is neural recovery?

A

Neurophysi level

Funcitoning relies on to original (pre-injury) processes

Q

What is recruitment?

A

Enlisting motor areas with capacity to contribute to lost motor function by may not normally have been contributing before injury

Not necessarily acquiring new function

Q

What is retraining?

A

Motor cortex adapts existing function or takes on NEW functions to support functional improvement.

Ex lost digit representation re-emerge in areas of the motor cortex that used to contain elbow or shoulder representations
