A Feasibility Study of Quantitative Motor Assessments in Children Using the Q-Motor Suite

Abstract

Q-Motor is utilized across various clinical trials in adults with Huntington's disease (HD) to provide quantitative, reliable assessments of motor abilities. With gene-knockdown therapies entering the clinic, development of preventative therapies for pediatric carriers of the HD mutation seems imminent. It is currently unclear if Q-Motor is useful for tracking changes in motor abilities in pediatric HD patients or at-risk youth, as most assessments have never been administered in children. We demonstrate the feasibility of administering Q-Motor tasks in a sample of children recruited from the community, and we show that Q-Motor is sensitive to age-related changes in motor abilities.
