Figure 2.

A model of the key attributes required for the ability to respond quickly to a perturbation.

Note: The afferent process shown is proprioceptive in nature, but vision and vestibular input must be accounted for as well. The central processes are related to inhibitory executive function and attention/simple reaction time. Although Complex RT_clin Accuracy (as RRTAcc) is depicted in the Figure, other measures of this critical neurocognitive attribute such as Stroop or Trails B testing is acceptable.
