[Purpose] The aim of this study was to evaluate the reliability, validity and clinical utility of the basic balance ability test (BBT) which we designed. [Subjects] Subjects were 122 patients with balance disorders hospitalized in five hospitals. [Methods] The BBT is composed of 25 tasks which are divided into three balance levels, including static balance, weight-shifting in the sitting and standing positions, step movement, and standing up from a therapeutic bed and sitting down. Each task was scored on a 3-point scale, 0 to 2, according to the stability levels of performance. Reliability of the BBT was evaluated by the test-retest method. The validity of the BBT was evaluated using the correlation between the total score of the BBT and the Berg balance scale (BBS). The utility of the BBT was assessed by the measurement time of BBT, and the relation between BBT and gait ability of the patients. [Results] The average ratio of agreement between two measurements was 81.6%. The correlation coefficient between the BBT and the BBS was 0.88. The mean measuring time for BBT was 8.6 minutes. And the total score of the BBT changed in accordance with the gait ability of the patients. [Conclusion] From the above results, we conclude that BBT has reasonable reliability, validity and clinical utility. [ABSTRACT FROM AUTHOR] |
