Background and purpose: We examined the correlation between the scores of the Postural Assessment Scale for Stroke Patients (PASS) and those of the Berg Balance Scale (BBS) among ambulatory patients with chronic stroke. If the PASS scores are strongly correlated with the BBS scores, the PASS would be a superior alternative for evaluation because it can be administered faster and is more comprehensive. Methods: The PASS and BBS scores of 23 independently ambulatory patients with chronic stroke were collected and analyzed using Spearman’s rank correlation. Because the BBS includes more items for assessing dynamic balance function, we also analyzed the correlation between the scores of the changing posture subscale of the PASS and the scores of the BBS. Results: The Spearman rank correlation coefficient (r) between the BBS and PASS scores was .93 (P<0.05), that between the changing posture scores and BBS scores was .87 (P <0.05). Conclusions: Our study indicated that among ambulatory patients with stroke, the PASS and BBS scores were strongly correlated. Thus, the PASS is a superior alternative for evaluating patients with stroke because it is faster to administer and more comprehensive. Contrary to our hy-pothesis, the degree of the correlation between the changing posture scores and the BBS scores was not higher than that of the correlation between the PASS and BBS scores. Nev-ertheless, we believe that the PASS is still a more effective test for evaluating balance func-tion among ambulatory patients with stroke.
