The scores of the Box and Block Test (BBT). a) Improvement of the BBT score. That is, the BBT score after training divided by that before training on the same day. The BBT test after training was conducted with SENS during the intervention period. The gray bar is the improvement rate for the intervention period, and the white bar is that for the observation period. The left bars show the result after 30 min training, and right bars show that after 60 min training. b) The BBT scores on each intervention day. Open squares denote the scores of BBT assessed without SENS before training. Filled circles denote BBT scores assessed with SENS after 60 min training. Open triangles denote BBT scores assessed without SENS after 60 min training. c) The score of BBT assessed without SENS before training throughout the control, the intervention and the observation period, plotted against the interval scale of time. The gray zone indicates the intervention period. To evaluate whether the patient was able to maintain the improved manipulation capability or not, BBT score assessed without SENS after 60 min training on the last day of intervention (Day 134) was marked by the broken line.
