Fig. 1. Bland-Altman plot for the difference between measures from the two test sessions against the mean of the two test sessions for each subjects The LOA for the SF-BBS and the SF-PASS ranged from -2.91 to 4.61 and -1.48 to 1.92, respectively. (a) Short form Berg Balance Scale (SF-BBS) (b) Short form Postural Assessment Scale for Stroke Patients (SF-PASS). : mean difference, the 95% limits of agreement (LOA). The 2 dashed lines define the 95% LOA (mean of difference ± 1.96 × SD of the difference).
