Abstract

Objective
The purpose of this study is to translate the Berg Balance Scale (BBS) to the Korean version (K-BBS) and to evaluate its reliability.
Method
With the agreement of Katherine Berg, the original editor of the BBS, two physiatrists and three physical therapists had translated the English version of BBS into Korean (K-BBS). This was back-translated into English by a Korean-American physiatrist fluent in English. After a 2- hour K-BBS education course, the video recorded K-BBS of 18 stroke patients were reviewed by nine examiners (four physiatrists and five physical therapists) to assess the inter- rater and the intra-rater reliability. Kendall's correlation co-efficient and Pearson's correlation coefficient were computed to assess the intra-rater and test-retest reliability, respectively.
Results
The inter-rater reliability was 0.97 at 2 separate evaluations with an interval of 10 days (p＜0.05). The intra- rater reliability was 0.95 (p＜0.05) in the physiatrist group and 0.97 (p＜0.05) in the physical therapist group.
Conclusion
We recommend that the Korean version of the Berg balance scale is a reliable instrument to be used in balance assessment of stroke patients. (J Korean Acad Rehab Med 2006; 30: 611-618)
