## 2 Materials and Methods
After the reach motion was completed, or a specified time passed, the center point was designated as the target, and the subject moved the indicator back to the center making \begin{table}

Table 1: Characteristics of participants at the start of robot training. the total movement count as two. This task was repeated in a clockwise direction around the circle, until each outer target had been touched. This entire cycle was repeated five times, and the 80 th reach motion ended the task. The RE indicated the distance from the point reached by the indicator to the target, and, whenever the indicator did not reach the target, the RE value increased. The PE evaluated the track of the indicator. Whenever the track of the indicator deviated from the optimal track, the PE value increased. The RE and PE were both averages of the values obtained during the 80 reach motions. For statistical analysis, a range of \(\pm\)1.96 of the mean values of the hemiplegic patients without complete sensory loss were set as the 95% confidence intervals and were compared against the scores of the patients with complete sensory loss.
