Essential tremor is a disorder that causes involuntary oscillations in patients while engaging in actions or while maintaining a posture. The patients have serious difficulties in performing activities of daily living such as eating food, drinking water, and writing. We have thus been developing an EMG-controlled exoskeleton to suppress tremors. In this paper, the extent of tremor suppression by using the proposed exoskeleton is reported. Thought an experiment, it confirmed that the amplitude of tremor while wearing the exoskeleton was 50〜70% smaller than that of no support case. This result indicated that an approach to use exoskeleton is effective way to suppress tremor. Toward the practical use, the fitting of the robot must be improved. As a future work, to make it possible to fit the robot automatically, we will define the effective point to suppress tremor originated from the particular point of the body.
