Discriminant ability of the Trunk Impairment Scale: A comparison between stroke patients and healthy individuals

Abstract

Purpose. The Trunk Impairment Scale (TIS) is a standardized scale to evaluate the trunk function in stroke patients. It was the aim of this study to determine the discriminant ability of the TIS by comparing stroke patients with healthy individuals. Further, the variables that had an influence on obtaining a high score on the TIS in healthy subjects were examined. Method. Forty stroke patients and 40 age- and sex-matched healthy individuals were included in the study. TIS scores from the stroke patients and healthy individuals were compared using the Wilcoxon ranked sum test. Results. Sub-scale and total TIS scores showed significant differences between stroke patients and healthy individual..
