Motor control and learning in individuals with early-treated phenylketonuria.

Although past studies have documented motor control impairments in individuals with early-treated phenylketonuria (ETPKU), much less is known regarding motor learning in ETPKU. The goal of the present study was to advance our understanding on this front.We isolated and examined motor kinematics associated with the learning of a rapid aimed limb movement in a sample of 40 individuals (13-34 years of age) with ETPKU and a matched comparison group...
