Table 4 Incidence of participants who exceeded the limit of the typical error indicating a change outside the normative standard for the parameter. The typical error is based on a database acquired in specific test-retest approaches for each of the parameters analyzed in the present study. The typical error is presented in the same unit as its respective parameter
