Psychometric analysis of the Friedreich Ataxia Rating Scale

Takeaway

  • The Friedreich Ataxia Rating Scale (FARS) neurologic examination (FARSn) and the modified FARS (mFARS) have appropriate item-subscale groupings, inter-subscale correlations, and internal consistency when assessed in a large cohort.

Why this matters

    This study endorses the use of the mFARS and FARSn to monitor the complex features of Friedreich Ataxia, including changes early in the disease course.
