75 participants diagnosed with PD were grouped by Hoehn and Yahr (HY) scores: Group 1 consisted of subjects with scores 1 or 2 (n = 52, mean = 25.42±0.76), while Group 2 consisted of subjects with scores 3 or 4 (n = 23, mean = 19.43±1.45). Mini Balance Evaluation Systems Test (MiniBEST) was used to quantify balance, then comparing it to different stages of the disease through Hoehn and Yahr (HY). The Unified PD Rating Scale (MDS-UPDRS), Life-Space Assessment (LSA) and Parkinson's Disease Questionnaire (PDQ-8) were performed to verify aspects associated with balance and mobility deficits such as severity of the disease and years since first symptom. Evaluations were performed during the "ON" period of medication. T-test and Spearman’s Correlation were performed in order to compare and correlate the independent samples, respectively.

Quantitative measurements of balance correlate with the course of the disease, severity of symptoms and social participation of individuals, therefore showing relation with Community Mobility. Also, miniBEST appears to be a good instrument to assist evaluation of motor symptoms in PD patients.
