Describe the cognitive demands of postural control and implications for dual-task stability and task performance.

-finite amount of cognitive attentional resources -when reaching our attentional limits one or multiple tasks decrease -reaction times are slowest when postural demands higher -attentional demands increase with balance challenge

Describe the pathophysiology of concussion

-k ions rush out of cell -Ca ions rush into the cell -metabolic dysfunction ensues

True/False: Symptom severity in initial days following BI is most consistent predictor of recovery rate

True
