DTWとMT法を用いた類似性を基準とする高齢者の側方リーチ動作の運動評価

―複数の動作特徴量による指標の構成―

The purpose of this study is to develop an evaluation index for the lateral reaching motion of elderly people using a simple measurement system with RGB-D sensors. Physical therapists often evaluate the motor function of elderly people visually. Therefore, if we can quantitatively evaluate motor functions, it is expected to reduce the workload of physical therapists and to allow elderly people to measure their own motor functions. In this study, we use DTW to extract features from time series data of movements. We propose an index that focuses on whether a person is able to perform actions equivalent to those of a healthy person by making judgments using the MT method based on the actions of a healthy person from multiple motion features.
