Abstract: There is no orthosis available to perform an active assistance to the rehabilitation of rheumatoid arthritis. In thisstudy, we developed new pneumatic actuators which were called membrane pneumatic actuators to produce an assist
orthosis. We presented that the force generated of the single actuator had the linearity to the air pressure supplied to theactuator and that the dynamic characteristics depended on the efficiency of an electropneumatic regulator from ourcharacteristics experiment. And we verified an effect of reduction by the assist orthosis with the actuator.
Key Words: Membrane Pneumatic Actuator, Rheumatoid Arthritis, Assist Orthosis, Linearity, Characteristics
