Abstract
This paper presents walking orthotic equipment that enables a person with mildly disabled limbs to use an ordinary toilet. The critical problem occurs as the narrow width of the toilet booth when a wheelchair user would like to use the ordinary toilet. On the other hand, if the wheelchair user can walk, this problem will be solved. In this case, the user has to realize the following motions: standing up from a wheelchair, walking to the toilet booth, and sitting down on the toilet seat. The equipment includes two modules: lower extremity orthosis with gas-springs and a pair of telescopic crutches. The gas-spring can be locked or free by pushing the "Lock button" to help the user when he is standing up, walking and sitting down. The telescopic Lofstrand crutch assists the user when he is standing up and sitting down in short length state, and assists the user in a standing position when changed into long length state.
