| Outline of Final Research Achievements |
The aim of this study was to develop a sensory-enhancing robot-aided rehabilitation system with tendon vibration for the upper limbs. The pilot study included 5 healthy subjects. Vibration stimuli at 100-150 Hz delivered to the dominant arm pronator enhanced the sensation of supination movement during robot-aided forearm pronation/supination exercise. Next study was performed to determine whether vibration could change a cortical activation pattern during robot-aided forearm pronation/supination in normal healthy subjects. Vibration stimuli at 100-Hz delivered to the pronator during supination of the forearm. We measured the cortical activation of the motor area during robot-aided exercise by means of a near-infrared spectroscopic imaging system. Vibration stimuli enhanced oxy-Hb increases in 4 of 6 subjects in the active-assisted mode, while the enhancement in oxy-Hb increases was observed only in 2 of 6 subjects in the passive mode.
