NCT01361867
First received: May 25, 2011

Last verified: March 2014
  Purpose

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.
