Sumario:BACKGROUND: Video recordings of neurological examinations are often used in clinical trials. The Scale for Assessment and Rating of Ataxia (SARA) is a widely used clinical scale for ataxic patients. Despite several advantages of video ratings, correlation between live ratings and remote video‐ratings has not been systematically investigated. OBJECTIVE: To compare live and remote video assessment of SARA. METHODS: Full SARA examinations of 69 patients with cerebellar ataxia were recorded on video. Live rating from site investigators were compared with remote video rating of three experienced ataxia clinicians using Bland–Altman analysis. RESULTS: Live and remote video ratings showed a high level of agreement for the complete score (bias = 0.09, with standard deviation = 2.00) and all single SARA items (bias <0.20 for all items). CONCLUSION: Remote video ratings of SARA are a reliable means to assess severity of ataxia.
