Résumé
Balance problems in Parkinson's Disease (PD) require appropriate evaluation. While the Mini-BESTest is commonly used to assess dynamic balance, some of its psychometric properties have not yet been addressed. What is the responsiveness and the Minimal Clinically Important Difference (MCID) of the Mini-BESTest in patients with PD? One-hundred forty-eight patients with PD underwent a treatment specific for balance skills (1-h session, three times/week for four weeks). All patients were initially evaluated with the Mini-BESTest and Activities-Specific Balance Confidence scale 5-levels (ABC-5L). Post-treatment, patients were assessed with the Mini-BESTest, ABC-5L and Global Rating of Change (GRC, both patient- and physiotherapist-rated). Responsiveness to treatment and MCID were calculated with distribution and anchor-based methods: effect size, area under the curve (AUC) of receiver operating characteristics (ROC), and correlations between evaluations (change in score of Mini-BESTest, ABC-5L, GRC). Eleven a priori hypotheses were formulated for testing responsiveness. The effect size of treatment measured with the Mini-BESTest was 0.44, revealing moderate responsiveness. AUCs were 0.75, 0.82 and 0.59 for the patient-rated GRC, physiotherapist-rated GRC and ABC-5L, respectively.

BACKGROUND
Balance problems in Parkinson's Disease (PD) require appropriate evaluation. While the Mini-BESTest is commonly used to assess dynamic balance, some of its psychometric properties have not yet been addressed.
RESEARCH QUESTION
What is the responsiveness and the Minimal Clinically Important Difference (MCID) of the Mini-BESTest in patients with PD?
METHODS
One-hundred forty-eight patients with PD underwent a treatment specific for balance skills (1-h session, three times/week for four weeks). All patients were initially evaluated with the Mini-BESTest and Activities-Specific Balance Confidence scale 5-levels (ABC-5L). Post-treatment, patients were assessed with the Mini-BESTest, ABC-5L and Global Rating of Change (GRC, both patient- and physiotherapist-rated). Responsiveness to treatment and MCID were calculated with distribution and anchor-based methods: effect size, area under the curve (AUC) of receiver operating characteristics (ROC), and correlations between evaluations (change in score of Mini-BESTest, ABC-5L, GRC). Eleven a priori hypotheses were formulated for testing responsiveness.
RESULTS
The effect size of treatment measured with the Mini-BESTest was 0.44, revealing moderate responsiveness. AUCs were 0.75, 0.82 and 0.59 for the patient-rated GRC, physiotherapist-rated GRC and ABC-5L, respectively. There was a moderate correlation between changes in the Mini-BESTest and patient-rated (r
SIGNIFICANCE
The Mini-BESTest showed moderate responsiveness for detecting treatment-related improvement in dynamic balance. A 4.0-point MCID value is useful to identify clinical effects of balance rehabilitation in a single patient with PD. Values ranging from 3.4 and 4.0 are recommended for interpretation of results at a group level.
