The Stroke-Balance Evaluation Systems Test (S-BESTest) is an assessment tool for assessing 6 domains of postural control impairments. However, consistency of its score over time and across multiple raters that used the S-BESTest in people with chronic stroke were necessary to be tested. Therefore, this study aimed to examine the reliability of the S-BESTest in chronic stroke patients. Three physical therapists examined the patients’ performance from the same set of ten video clips on 2 separate occasions performed 10 days after the first occasion. The performance’ scores were based on scoring criteria of the S-BESTest (English version). Scores from the first and second occasions of each rater were used to determine intra-rater reliability using intraclass correlation coefficient (ICC) model 3,1. The scores from the first occasions were used to determine inter-rater reliability using ICC model 2,1. The intra-rater reliability of the S-BESTest total score and domain scores were excellent with ICC (95% CI) of 0.96-0.99 (0.85-0.99) and 0.93-1.00 (0.71-1.00), respectively. The inter-rater reliability of the S-BESTest total score and domain scores were excellent with ICC (95% CI) of 0.97 (0.93-0.99) and 0.91-0.98 (0.76-0.99), respectively. Clear instructions of how to score and how the rater practice and discuss the session with an experienced physical therapist are necessary for such degree of reliability of the S-BESTest. Further study should examine validity properties of the S-BESTest to ensure measurement properties before using it in assessing postural control impairments in people with chronic stroke.
