Internal responsiveness After 2 and 4 weeks of rehabilitation, the majority of patients showed improvement of balance performance as demonstrated by significant increases in total scores of the S-BESTest, Brief-BESTest, Mini-BESTest, and BESTest (Table VI). Those score changes were larger Table IV.

The number of patients who had no change in score post-rehabilitation was seen only when assessing with the BESTest. The highest number of those who had no change in score was found when using the Brief- BESTest at 2–4 weeks post-rehabilitation. The SRM of the S-BESTest, Brief-BESTest, Mini-BESTest, and BESTest were large, ranging from 1.19 to 1.57, in- dicating sufficient internal responsiveness. Minimal Table V.
