Intercorrelations between predictor variables were analyzed in order to determine which
variables were highly correlated. Table 3 displays the correlation coefficients of the risk
factors studied that are significant at the 0.01 level. The results illustrated that the total
Berg balance scale score and the total ABC score had the highest correlation followed by
the total Berg balance scale score and simple reaction time followed by total ABC score
and simple reaction time. Frequency mode in the anterior–posterior and lateral directions
were not highly correlated with other dependent variables. Due to the fact that many of the functional balance tests have many similarities, it was hypothesized that a second model
might be more effective in the hope of eliminating any redundancies found within the Berg
balance scale and the ABC scale.
