Robotic Assessment of Lower Extremity Motor Learning

This study is ongoing, but not recruiting participants.

The investigators hypothesize that the motor learning processes observed in the lower extremity will be similar to those seen in upper arm experiments. Furthermore, the investigators hypothesize that lower extremity motor learning can be quantified with an adapted model of the force-field adaption paradigm (FFAP) introduced by Shadmehr et al. for studying motor learning in the upper extremities.
