- ICARS [ Time Frame: baseline and 6 months ]
International Cooperative Ataxia Rating Scale (ICARS):
ICARS consists of a one-hundred-point semi-quantitative scale based upon 19 simple testing manoeuvres compartmentalized into postural and stance disorders, limb ataxia, dysarthria and oculomotor disorders and has been previously used in this patient population with good inter-rater reliability.
Scores for each subscale quantify the extent of ataxia in each clinically important area. Subscale scores are summed to give a total score ranging from 0 (best) to 100 (worst).
