Principal component analysis of standardized residuals confirmed the unidimensionality of the test. All items fit the Rasch analysis. Person ability-item difficulty matching was good. Person reliability was 0.96, and the patients were divided into 9 strata. The keyform for the BBS will enable clinicians and investigators to estimate patients’ postural balance ability and monitor their progress.<br /><strong>Conclusion:</strong> The BBS has strong measurement properties.

The Berg Balance Scale (BBS) measures a person’s ability to maintain postural balance. Several analyses were performed to investigate the measurement properties of the BBS in patients who have had a stroke. Then, a keyform tool was generated and some strata (levels) determined that separate patients according to postural balance ability. A keyform can help therapists to identify items that a patient finds relatively  difficult. Use of a keyform can contribute to both rehabilitation goal-setting and planned interventions for patients. The strata can be  used to detect and measure changes in a patient’s postural balance ability. The findings of this study demonstrate that the BBS has  strong measurement properties and provides an appropriate keyform and 9 strata. Use of these tools can facilitate the rehabilitation of patients with stroke through quantification of a patient’s postural balance ability.</p> ER -
