ランニング時の腕振りの効果を考慮したアマチュアアスリート用リハビリ装置の設計及び評価

抄録

The current increase in health awareness has led to greater attention to exercise. However, the growing number of competitors in various sports has caused a concomitant increase in the number of injuries during matches. After an injury, an immediate return to competition is difficult. Thus, there is a need to develop rehabilitation devices that can provide an environment in which the amateur athletes can safely be rehabilitated while determining his or her own state of recovery even if no athletic trainer is available. Conventional rehabilitation devices have emphasized recovery of cardiopulmonary function or the function of specific joints, with little to no development of devices aiming for an early return to competition.

In the previous work, we aimed to develop a device which reproduces the motion of the leg during running by using a planar 6-link mechanism and reduces the load on the leg. Furthermore, we focused on the arm swinging effect during running, and tried to develop a device that can acquire linkage properties of the body by adding arm motion during running using a slider crank mechanism. As a result of experiments to measure motion, it was confirmed that the arm reproducibility of the arm swing is insufficient in the arm mechanism of the device.

In this research, we try to improve the usefulness by adding a new function that enables tracking of the locus of the arm. Further, in order to evaluate the utility as a rehabilitation device in a produced device, experiment of muscle action potential is conducted.
