Single-rater use is adequate for the PBS and the SARA but limited for the BARS in this floor-dominated population. Age-referenced interpretation of the PBS is warranted. Establishing the reliability and normative characteristics of these scales in typically developing children will facilitate more accurate interpretation of pediatric ataxia and balance...
