Measurement system of gait performance for estimation of fall experience of elderly people is introduced. Dual task walk test, in which recall question like the name of Japanese prefecture is imposed on subjects while walking, is conducted. In addition gait parameters such as stride length, walk rate, toe clearance and toe angle of each step are measured using tiptoe-mounted inertial sensor and subject's voice is recorded using voice recorder, respectively. A tablet type of computer with specially developed application is used to wirelessly control the inertial sensor and voice recorder, to count the number of answer and to record the personal information of subjects. The relation between the change rate of difficulty of the question as the required time for one answer and that of the gait parameter is compared. The experimental results show that the change rate of the gait parameter for fall experienced subjects is larger than that of the difficulty of the question and can be used to classify the fall experience of elderly people.
