Step velocity

1. Posterior cortical atrophy has no effect on step velocity in humans.

   “no significant differences were found for pattern and variability outcomes or between PCA and AD groups ( p >0.05; Figure 1).”

2. Posterior cortical atrophy increases step velocity in humans.

   “The PCA group walked faster, spent more minutes walking, took more steps and walking bouts per day ( p <0.01 for all) than the LBD group”
