Abstract [en]

When physiotherapists are using clinical balance instruments and computerized balance equipments there is a need to establish the reliability of the instrument before using them in clinical practice. The aim of this study was to determine the test-retest reliability of Balance Master (BM), a computerized balance equipment, when using the tests Step Up/Over and Step Quick/Turn. Method: Thirty-three community-dwelling elderly people between 65 and 81 years participated in the study. 52 % were females, cognitive status estimated by the Mini mental state examination was 28,5 (SD+/-1,5). The subjects were independent in ADL according to Barthel ADL Index and 97 % of the subjects ambulated independently. Outcome measures derived from Step Up/Over’s variables: Lift up Index, Movement time and Impact Index: Step Quick/Turn’s variables Turn time and Turn sway. Data were collected on two occasions, one week apart. Relative reliability was calculated as the intraclass correlation coefficients (ICCs): two-way mixed effect model was used. Absolute reliability was calculated according to Bland & Altman’s 95 % Limits of Agreement (LOA). Results: The ICCs between 0.63 and 0.83 indicated that the relative test-retest reliability was good to excellent for Step Up/Over and Step Quick/Turn. The values for absolute reliability (LOA) were provided for each variable of Step Up/Over and Step Quick/Turn. In conclusion these two tests are reliable tests and it indicates that they can be useful in clinical practice, by testing forces and centre of gravity during locomotion. There is a necessity to determine the validity of Step Up/Over and Step Quick/Turn against clinical balance instruments.
