Outline of Final Research Achievements

A randomized controlled trial of a simple training-assistance robot (MA2) was performed for 45 chronic stroke patients, who were assigned to the robot or control groups. The robot group underwent 20 minutes MA2-assisted training and 40 minutes usual care for 2 or 3 sessions a week, and 24 sessions in total; the control group underwent 60 minutes usual care the same number of times. The Fugl-Meyer Assessment for upper extremity (FMA), the modified Ashworth scale, range of motion (ROM), Motor Activity Log (MAL), and Stroke Impact Scale were measured before and after the intervention. The robot group showed a significantly greater change in the QOM of MAL than the control group, and tended to show an improvement in the extensor synergy and normal reflex activity of FMA, and in the wrist flexion and extension of ROM. Before-after comparisons within the robot group showed a significant improvement in 16 items based on all measurements, while only 2 items within the control group.
