Validity and Reliability of Star Excursion Balance Test for Dynamic Balance Assessment in Stroke Patients / 中国康复理论与实践

ABSTRACT

Objective:To apply Star Excursion Balance Test (SEBT) in evaluating dynamic balance function in stroke patients. Methods:From September, 2018 to November, 2019, 38 stroke hemiplegic patients of Brunnstrom IV and above who could walk independently were included. They completed SEBT by two testers; the anterior, posteromedial and posterolateral extension standardized distance of the affected leg support were recorded. One of the testers measured SEBT again the day after the next day. The intraclass correlation coefficient (ICC) was calculated. The limits of stability on different directions were measured with active balancer EAB-100 (EAB) and tested with Timed 'Up & Go' Test (TUGT) by the third tester. The correlation of SEBT to EAB and TUGT was analyzed with Pearson correlation coefficient. Results:ICCs of three directions was 0.892 to 0.951 between testers, and 0.888 to 0.963 of test-retest. The standardized distance of three directions of SEBT correlated with the anterior and lateral stability limits of EAB (r = 0.479 to 0.671, P < 0.05), as well as TUGT (r = -0.557~-0.633， P < 0.05). Conclusion:SEBT is valid and reliable for evaluation of the dynamic balance for stroke patients of Brunnstrom IV and above who can walk independently.
