The purpose of this study is to clarify the circumstances in which the residents' postures are changed in a nursing home. The residents' behavior tracking survey and the interviews with the staff were performed for this study. The results are as follows. 1)As the body functional capacity declines, the ratio of staying in a common space decreases. Some with akathisia or with dysphagia were observed bedridden for the whole day. 2)As the body functional capacity declines, the variation and the number of the residents' postures decreases. 3)Among the postures observed of those who are unable to transfer or with akathisia and dysphagia. "sitting on a wheelchair" holds 100% of the data in the common spaces. And some were observed staying seated for quite a long time in one day
