Evaluation of the specificity of selected dynamic balance tests.

Many researchers have suggested that balance is not a general motor ability but rather is specific to the task which is performed. The purpose of the present study was to examine the relationship between a laboratory test (stabilometer) for assessing dynamic balance and three field tests: the Modified Bass Test, Balance Beam Speed Test 1 (forward walking), and Balance Beam Speed Test 2 (sideward walking). In addition, associations of whole body reaction time with scores of the four tests of dynamic balance were assessed in 54 undergraduate students. Pearson coefficient of determination indicated no significant correlation between the time participants were in balance on the stabilometer and on any of the three field tests. Body reaction time was significantly correlated with scores on the four tests. These results give further support to the specific character of dynamic balance since all tests seemed to measure different aspects.
