Minimal clinically important difference of the Kansas University standing balance scale in patients with acute-to-subacute stroke using two external anchors

The minimal clinically important difference for the KUSBS was 0.5 for patients requiring walking assistance and 1.5 for those needing maximal assistance with daily activities. Alternative balance assessment tools may be more suitable for patients who do not require assistance. Our study findings emphasize the importance of incorporating qualitative balance assessment tools, such as the KUSBS, alongside traditional quantitative measures, such as the BBS, to provide a more comprehensive evaluation of post-stroke balance function.
