Abstract

It is known that falls in the daily life of the elderly occur frequently during walking and rising up and greatly affect their quality of life. In the previous study we obtained the COG-heel horizontal distance and the COG horizontal velocity when the subjects performed rising up under the “fastest” or “slowest” velocity task. These seat-off parameters which were an indicator of the stability in rising from a chair were defined based on the relationship between them. In this experiment with healthy adults as subjects the seat-off parameters were found to become a different distribution because of the rising up strategies of each subject. Moreover, based on the relationship between the seat-off parameters and motor function, they could become an index expressing current fall risk and predicting future fall risk.
