Appropriate for studies of Friedreich’s ataxia? Subjective and objective measures of health: During the writing of this paper J. In this ahaxia, a modified kinetic functions subscale would lack significant ceiling effects in any item and would be sensitive across a wide range of disease severities.

The scale items with a dynamic range across all disease severity stages were scale items 10— The results presented so far add to the understanding of the relative contribution of individual ICARS subscales and items to the total ICARS rating in relation to disease progression and severity.

In addition, the scaling properties were assessed using standard statistical measures. We next analysed the relative contribution of individual scale items to the total score in dependence of disease progression Fig.

For motor activities of the four extremities itemsassessments are performed bilaterally, and the mean values are used to obtain the total score. These findings are consistent with the aforementioned floor and ceiling effects, for which the same three items matched better with the respective other subscale.

J Neurol Sci ; The SARA is a tool for assessing ataxia. To visualize the dynamic range of each of the 19 scale items in relation to disease severity, we produced a heat map with the minimum item score indicated in green, the maximum item score indicated in red and the dynamic range in between as green—red colour spectrum Fig. Next generation sequencing for molecular diagnosis of neurological disorders using ataxias as a model.
