Sensitivity to change and responsiveness of the Balance Evaluation SystemsTest (BESTest) Mini-BESTest and Brief-BESTest in patients with subacute cerebralinfarction

摘要

[Purpose] To compare the sensitivity to change and responsiveness of the BalanceEvaluation Systems Test, Mini-Balance Evaluation Systems Test, and Brief-BalanceEvaluation Systems Test in patients with subacute cerebral infarction. [Participants andMethods] Thirty patients with subacute cerebral infarction participated in this study. TheBalance Evaluation Systems Test, Mini-Balance Evaluation Systems Test, Brief-BalanceEvaluation Systems Test, Berg Balance Scale, and ambulatory ability were assessed onadmission and discharge. Sensitivity to change was calculated using the effect size,standardized response mean, and relative efficiency. Responsiveness was analyzed bycomparing the ability of the difference between the scores of the balance assessments atadmission and discharge in classifying the participants’ ambulatory independence.[Results] All assessments showed significant improvement from admission to discharge. Theeffect size of the three versions of the Balance Evaluation Systems Test ranged from 0.41to 0.69. The standardized response mean ranged from 0.75 to 1.28. The cutoff score was16.7% for the Balance Evaluation Systems Test, 5.5 points for the Mini-Balance EvaluationSystems Test, 1.5 points for the Brief-Balance Evaluation Systems Test, and 3.5 points forthe Berg Balance Scale. [Conclusion] The sensitivity to change of the three versions ofthe Balance Evaluation Systems Test was high or moderate. However, the Mini-BalanceEvaluation Systems Test had the highest responsiveness, as determined with the extent ofambulatory independence.
