Abstract

Background: The Balance Evaluation Systems Test (BESTest) and its abbreviated version, the Mini-BESTest are clinical examination of balance impairment, but its psychometric properties have not yet been tested in European Spanish. We aimed to assess the psychometric properties of BESTest and Mini-BESTest in Spanish in community-dwelling elderly people.

Methods: We designed a cross-sectional transcultural adaptation and validation study. Convenience sample of thirty (N-30) adults aged 65 to 89 years old without balance problems were recruited. Two physiotherapists assessed participants at the same time. Internal consistency of Spanish BESTest and Mini-BESTest was carried out by obtaining the Cronbach Alpha. The reproducibility between raters was studied with the Intraclass Correlation Coefficient. The Pearson correlation coefficient was calculated by comparing the relationship between the BESTest, mini-BESTest, Berg Balance Scale (BBS) and Falls Efficacy Scale-International (FES-I).

Results: BESTest and Mini-BESTest showed good internal consistency. BESTest and Mini-BESTest total scores showed an excellent inter-rater agreement. There was a significant correlation between total score of the BESTest and the Mini-BESTest (r = 0.65; p < 0.001). BESTest had a moderate association with BBS and a strong association with FES-I. Mini-BESTest had a fair correlation with BBS and FES-I. Total scores obtained by women at BESTest and at Mini-BESTest were significantly lower than those reached by men. The differences observed in all the test when disaggregating data by sex require further research.

Conclusions: Spanish versions of BESTest and Mini-BESTest are comprehensible for new raters. They are reliable tools to provide information on which particular balance systems show impairment in community dwelling older adults. Elderly women had a worse quality of balance and a greater perception of their risk of falling.

Trial registration: This study was registered in ClinicalTrials.gov with NCT03403218 on 2018/01/17.
