Application of Quantitative Motor Assessments in Friedreich Ataxia and Evaluation of Their Relation to Clinical Measures

Friedreich's ataxia (FRDA) is a rare autosomal-recessive slowly progressive neurodegenerative disorder. As common clinical measures for this devastating disease lack sensitivity, we explored whether (a) the quantitative motor assessments of the Q-Motor battery can enhance clinical characterisation of FRDA; (b) clinical measures can predict Q-Motor outcomes and (c) Q-Motor is sensitive to longitudinal change. At baseline 29 patients and 23...
