Equilíbrio postural de idosos com provável doença de Alzheimer: análise comparativa entre as fases leve e moderada

Abstract

Study compared the postural balance between older adults with mild (Clinical Dementia Rating - CDR 1) and moderate (CDR 2) Alzheimer’s disease, through the Timed Up and Go Test (TUGt) (simple task, motor and cognitive dual-task) and Clinical Test of Sensory Interaction on Balance (CTSIB). Forty older adults were divided into CDR 1 (n=26) and CDR 2 (n=14) groups. Performance in simple TUGt, motor TUGt, and cognitive TUGt were significantly lower in the CDR 2 group (p<0.05), with greater impairment in dual-task situations. No significant differences between groups were observed in the CTSIB. In conclusion, postural balance is different between mild and moderate phases when a cognitive demand is added to the task, and this impairment is more accentuated in dual-task situations.
