FARS-ADL does not detect ataxia, but in this population at risk for ataxia, it might help investigators to assume which subjects are already ataxic in the temporary impossibility of using the gold-standard method SARA. We aimed to test if FARS-ADL could distinguish subjects with SARA score > = 3 (ataxics) among persons belonging to families with spinocerebellar ataxia type 3/Machado-Joseph disease (SCA3/MJD). 1A Correlation between the Scale for Assessment and Rating of Ataxia (SARA) and Friedreich Ataxia Rating Scale-activities of daily living (FARS-ADL) scores.
