Abstract
There are around one million disabled people who can't walk due to disease or accidents. In order to assist their walking, many kinds of gait orthosis have been developed. Especially, Hart Walker is one of the most sophisticated orthosis for improving walking-functions. Then we have been developed "Active Walker" by implementing McKibben artificial muscles to Hart Walker. Active Walker is able to perform various gait patterns for training. However, since Active Walker needs special adjustment by physiotherapists, it is unsuitableness for early rehabilitation. On the other hand, it is important to recover walking-functions soon after diseases or accidents. Then we have developed new Active Walker that has simple adjustment mechanisms for early rehabilitation.
