Ataxia quiere decir torpeza motora o la pérdida de coordinación que
no sea causada por debilidad muscular. La palabra “ataxia” puede
ser empleada simplemente para referirse a la descoordinación o, de
manera más específica, para denotar una enfermedad degenerativa
del sistema nervioso.

Friedreich ataxia, although rare, is the most prevalent inherited ataxia. Recent insight into the disease pathogenesis is creating new hope for effective therapies. The purposes of this update are:(1)to review the etiology, presentation, and progression of Friedreich ataxia and (2) to describe a comprehensive physical therapist examination emphasizing valid and reliable performance measurements associated with disease progression.
