Abstract

BACKGROUND AND PURPOSE

Mini-Balance Evaluation Systems Test (mini-BESTest) is a widely used measure to assess balance impairments. This study aimed to assess the validity, reliability, responsiveness, and minimal clinically important change (MCIC) of the Persian mini-BESTest among ambulatory People with Multiple Sclerosis (PwMS).

METHODS

Fifty ambulatory PwMS participated in this study. Persian mini-BESTest validated against Berg Balance Scale (BBS) and Timed-Up and Go (TUG) with/without a cognitive task. To assess the reliability, the Persian mini-BESTest was re-administered for a sample of 30 participants after 1 week. Also, 32 PwMS were tested before and after a 4-week of balance and gait training to assess the responsiveness.

RESULTS

No floor/ceiling effect was found for the mini-BESTest total score. There were significant excellent correlations (p < .001) between mini-BESTest and BBS (r = 0.71), TUG (r = -0.76), and cognitive TUG (r = -0.73). No strong correlations were observed between the subscales (r = 0.37-0.55). Test-retest reliability and internal consistency of Persian mini-BESTest total score were excellent, with Intra-class Correlation Coefficient (ICC and Cronbach's alpha level of 0.89 and 0.80, respectively. The minimal detectable change was 4 points. The Persian mini-BESTest had acceptable responsiveness (AUC = 0.83), and MCIC was 5 points.

CONCLUSION

The Persian mini-BESTest is a valid, reliable, and responsive measure of balance performance in Iranian ambulatory PwMS.

摘要

背景与目的

Mini-Balance Evaluation Systems Test（mini-BESTest）是一种广泛用于评估平衡障碍的测量工具。本研究旨在评估适用于伊朗活动期多发性硬化症患者（PwMS）的波斯语 mini-BESTest 的有效性、可靠性、反应度和最小临床重要变化（MCIC）。

方法

50 名活动期 PwMS 参与了本研究。波斯语 mini-BESTest 与 Berg 平衡量表（BBS）和计时起立行走测试（TUG）进行了验证，包括有无认知任务。为了评估可靠性，对 30 名参与者中的样本在 1 周后重新进行了波斯语 mini-BESTest 测试。此外，对 32 名 PwMS 在 4 周的平衡和步态训练前后进行了测试，以评估反应度。

结果

mini-BESTest 总分无地板/天花板效应。mini-BESTest 与 BBS（r=0.71，p<0.001）、TUG（r=-0.76，p<0.001）和认知 TUG（r=-0.73，p<0.001）之间存在显著的优秀相关性。分量表之间没有观察到强烈的相关性（r=0.37-0.55）。波斯语 mini-BESTest 总分的测试-重测信度和内部一致性非常好，组内相关系数（ICC）和 Cronbach's alpha 分别为 0.89 和 0.80。最小可检测变化为 4 分。波斯语 mini-BESTest 具有可接受的反应度（AUC=0.83），MCIC 为 5 分。
