This figure of FMA change scores shows the sample means and SDs at each baseline evaluation and each posttraining time point by intervention groups. P was based on paired t tests. Scores at the baseline demonstrate stability and were without significant between group differences. The within group change from baseline to final showed a significant benefit for both robotic groups: planar 2.79±3.82 (P=.005) and planar with vertical 1.69±2.19 (P=.005). This benefit was also seen from baseline to follow-up: planar 3.27±3.27 (P=.002) and planar with vertical 2.51±3.33 (P=.007).
