Development of a new instrument for evaluating leg motions using acceleration sensors (II).

Objective: The purpose of this study was to investigate the characteristics of the average acceleration of elderly people during walking.

Method: The subject cohort comprised nine men and 21 women aged ≥63 years. Subjects walked a 10-m straight course (walk test) which required stepping over six obstacles (hurdle walk test).

Development of new instrument for evaluating leg motions using acceleration sensors.

The purpose of this study is to develop a new system for measuring leg motions using a portable three-dimensional accelerometer. The measuring system is composed of acceleration sensors (Micro Stone, MA3-10Ac), a data logger, a data reader, and a personal computer. The personal computer draws a graph of the acceleration of movements (i.
