Study on the safety of a patient who stands up from a chair with a crutch , Hirokawa, N; Nishiyama, E; Hasegawa, N; Itose, K; Shibue, T; Hayami, T; Sawai, T; Ohmasa, M , Proceedings of 6th International Conference on Applied Human Factors and Ergonomics (AHFE 2015) and the Affiliated Conferences , 3 , 74 , 81 , Jul. 2015
   Summary:© 2015 The Authors This study investigates the safety and ease with which a patient stands up from a chair using a crutch, based on the trajectory of the center of gravity (CG) of the body and subjective impressions. In the study, three participants are made to stand up from a chair using a pair of crutches in seven postures that are combinations of different foot positions, crutch positions, body positions, and eye lines to consider their effects. When standing up from the chair, the CG of the body is measured by a stabilometer, and the safety and ease of standing up are determined from the trajectories, their lengths, and subjective impressions. This study suggests that standing up from the chair with a crutch position that is nearer to the body than normal is appropriate.
