213 Development of a New Stick for Convenience Improvement of the Users

It is very important for the user of a walking stick while walking to support their weight with the stability of the stick. So, for the improved convenience of the users, we have developed a new stick based on the principles of biomechanics. In this paper, the shape of the stick as decided by new design concepts is outlined, and we have manufactured for trial of the stick using an ultra-high speed 5-axis vertical machining center. It is clarified that the sticks of the trial production are able to reduce the load to knee while walking more than the usual stick. With these results in mind we explain why and how the new stick design is more effective.
