| Outline of Final Research Achievements |
Four Square Step Test（FSST） has been reported as a dynamic balance evaluation of falls. However, the FSST is only a time measurement that reciprocates four squares. We developed a device that can decompose moving motion in 8 directions around, such as front, back, left and right, and detect the direction which took longer time. In addition, this device can also perform random movement exercises specialized in a weak movement direction.
As a result of intervention training conducted on 25 subjects, reduction of wobbling leading to falls, shortening of weak movement time, improvement of lower limb muscle strength was confirmed. It was inferred that the lower limb muscular strength and the weak movement time improved by random and rapid load transfer to the surrounding eight directions. Lower limb muscular strength has the greatest influence on fall risk, and its improvement may have led to a reduction in waving.
