The Human Movement Science Laboratory is equipped to study automatic and voluntary motor coordination and adaptations using established and novel experimental paradigms such as surface perturbations, treadmill locomotion, forward fall, obstacle crossing and optical prism adaptation. Human models include healthy young and older individuals and those with neurologic conditions, such as Parkinson's disease.
