ABSTRACT

Purpose:This study were to examine the test-retest and inter-rater reliability as well as the concurrent validity,and convergent validity of the 2 simplified Postural Assessment Scale for Stroke:5itmes-3Level(PASS:5i-3L) &Berg Balance Scale:7items-3Level(BBS:7i-3L), and comparison between the original measures(PASS, BBS). Methods:A total of 33 patients participated in this part of the study. The 2 middle scores of the center of the PASS were averaged(ie, 0-1.5-3) to form the PASS-3Level. Similarly, the 3 level in the center of the BBS were collapsed to a single level(ie, 0-2-4) to from the BBS-3level. To examine test-retest reliability the PASS-3L and BBS-3L was administrated to each participant by rater A in 2 testing sessions 3days apart. To allow evaluation of inter-rater reliability the was rated simultaneously rater B(PASS, BBS-3L), C(BBS, PASS-3L) in the latter testing session. The reliability index(intra-class correlation coefficient, ICC2,1) of both simplified PASS-3L &BBS 3L was used to examine the Test-retest and inter-rater reliability. We examined the distribution, concurrent validity, and convergent validity(Spearman correlation coefficient) of the data obtained with the simplified and original measures. Results:The PASS-3L, BBS-3L showed high test-retest(ICC2,1= .96, .97, respectively) and inter-rater reliability (.97, .96, respectively). and Reliability for single item scores were good(range, PASS-3L=.88∼.96, BBS-3L= .86∼.93). The internal consistency of the PASS-3L, BBS-3L were high(Cronbach's α coefficient =.70, .80,respectively). The PASS-3L, BBS-3L showed high concurrent validity(r=.80∼.92, p<.01) and convergent validity with the FM-B, MBI, & FM-M score(r=.55∼.82, p<.01). Conclusion:The PASS-3L, BBS-3L showed high reliability and moderate to good validity so 2 simplified 3-Level scale is a useful clinical tool for evaluating balance in stroke patients. The both simplified PASS, BBS 3-Level scale was found to be adequate for assessing balance in patients with stroke.
