Objective: To examine the test–retest reliability, responsiveness, and clinical utility of the machine learning-based short form of the Berg Balance Scale (BBS-ML) in persons with stroke. Design: Repeated-measures design. Setting: A department of rehabilitation in a medical center. Participants: This study recruited 2 groups: 50 persons who were more than 6 months post-stroke to examine the test–retest reliability, and 52 persons who were within 3 months post-stroke to examine the responsiveness. Test–retest reliability was investigated by administering assessments twice at a 2-week interval. Responsiveness was investigated by gathering data at admission and discharge from the hospital. Interventions: Not applicable. Main Outcome Measure: BBS-ML. Results: The BBS-ML exhibited excellent test–retest reliability (intraclass correlation coefficient=0.99), acceptable minimal random measurement error (minimal detectable change %=13.6%), and good responsiveness (Kazis’ effect size and standardized response mean values≥1.34). On average, the participants completed the BBS-ML in around 6 minutes per administration. Conclusions: Our findings indicate that the BBS-ML appears an efficient measure with excellent test–retest reliability and responsiveness. Moreover, the BBS-ML may be used as a substitute for the original BBS to monitor the progress of balance function in persons with stroke.
