Abstract
OBJECTIVES: To examine both group- and individual-level responsiveness of the 3-point Berg Balance Scale (BBS-3P) and 3-point Postural Assessment Scale for Stroke Patients (PASS-3P) in patients with stroke, and to compare the responsiveness of both 3-point measures versus their original measures (Berg Balance Scale [BBS] and Postural Assessment Scale for Stroke Patients [PASS]) and their short forms (short-form Berg Balance Scale [SFBBS] and short-form Postural Assessment Scale for Stroke Patients [SFPASS]) and between the BBS-3P and PASS-3P. DESIGN: Data were retrieved from a previous study wherein 212 patients were assessed at 14 and 30 days after stroke with the BBS and PASS. SETTING: Medical center. PARTICIPANTS: Patients (N=212) with first onset of stroke within 14 days before hospitalization. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Group-level responsiveness was examined by the standardized response mean (SRM), and individual-level responsiveness was examined by the proportion of patients whose change scores exceeded the minimal detectable change of each measure. The responsiveness was compared using the bootstrap approach. RESULTS: The BBS-3P and PASS-3P had good group-level (SRM, .60 and SRM, .56, respectively) and individual-level (48.1% and 44.8% of the patients with significant improvement, respectively) responsiveness. Bootstrap analyses showed that the BBS-3P generally had superior responsiveness to the BBS and SFBBS, and the PASS-3P had similar responsiveness to the PASS and SFPASS. The BBS-3P and PASS-3P were equally responsive to both group and individual change. CONCLUSIONS: The responsiveness of the BBS-3P and PASS-3P was comparable or superior to those of the original and short-form measures. We recommend the BBS-3P and PASS-3P as responsive outcome measures of balance for individuals with stroke.
