Reliability and Validity of Turkish Version of The Brief-BESTest in Stroke Patients.

BACKGROUND: The Brief-BESTest is the short version of the BESTest used to evaluate balance and fall risk in a multiple disease populations. The clinicians need practical, short application scales to evaluate the risk of falling, balance and rehabilitation results. OBJECTIVE: This study aims to investigate the validity and reliability of the Turkish version of the Brief-BESTest (Brief-BESTest-T) in stroke patients. METHODS: This study included a total of 40 subacute and chronic stroke patients (mean age of 60.28 ± 9.96 years). The Brief-BESTest, Berg Balance Scale (BBS), Timed Up and Go Test (TUG), Functional Reach Test (FRT), Falls Efficacy Scale (FES) and 10 m walking test were applied to the patients. RESULTS: A strong correlation was observed between the1st and 2nd evaluation Brief-BESTest-T total scores (r = 0.933). Cronbach's alpha coefficient was excellent. According to the correlation analysis performed to test the inter-rater reliability, a very high correlation (r = 0.906) was observed between the Brief-BESTest-T total scores. A high correlation was found between the Brief-BESTest-T and BBS and TUG, while a moderate correlation was found between the FRT, FES, and 10 m walking test. The clinical cut-off point for the Brief-BESTest - T was determined to be 9 points with an AUC of 0.872. There were no floor and ceiling effects found. CONCLUSIONS: This study showed that the Brief-BESTest-T had excellent internal consistency, intra-rater, and inter-rater reliability. Its concurrent, discriminant, and known-groups validity were also good and had no substantial floor and ceiling effects.
