Fig 1 Setup for the Drawing Test. A hemiplegic poststroke subject with an Ashworth Scale score of 1 is moving the magnetic mouse from point A to B with his paretic arm. The hand path is recorded by a computer.

Fig 2 (A) Geometric outcome measures for target movement from A to B, shown by means of a schematic hand path. Ym is the remaining radial distance, and Xm is the remaining tangential distance to the desired endpoint B. (B) Four repetitions of actual hand path as recorded for 1 subject with an Ashworth Scale score of 2. The left path was performed with the paretic arm and the right path with the nonparetic arm.

Fig 3 Dependency of outcome measures on the Ashworth Scale score. (A) Remaining radial distance Ym to desired endpoint B. (B) Logarithmic SD in tangential direction log(e(x)). (C) Remaining tangential distance to desired endpoint B. (D) Movement duration T. Each of the 4 outcome measures is presented as a pair of 2 columns, where the left column depicts the measures for the nonparetic arm and the right column for the paretic arm. Group mean values are given for subjects who were hemiplegic on the dominant side (squares) and on their nondominant side (triangles). All values were averaged over 4 trials and vertical bars denote the 95% CI.

Fig 4 Reproducibility of geometric outcome measures (A) Ym and (B) log(Xm) for the paretic arm on either side (dominant or nondominant). The spread of the bars denotes the 95% CI.

Fig 5 Scatterplot of the outcome measures Ym and log(e(x)). Each dot represents the measurements for a single subject. The fitted linear multiple regression equation is depicted as a contour plot with lines representing equal Drawing Test (DT) scores of 0, 1, 2, and 3. Subjects with dots between 2 consecutive lines have a Drawing Test score with a corresponding range and should also have the same range of Ashworth scores. This does not hold for 4 cases, which are circled and labeled with the Ashworth scores assigned by the expert.
