Research Abstract |
Estimation method of possibility of a fall is investigated using gait parameter during dial-task walking. Using inertial sensor and distance sensor mounted on tiptoe of both feet, measurement method of gait parameters including stance width is proposed. Then, it is found that the deterioration of gait performance during dual-task walking depends on subjects’ specialties. Finally, from the dual-task walking experiments for elderly persons, the relation between the deviation of gait parameter and the reduction of the number of answers can be used to estimate the possibility of a fall.
