Abstract

In recent years, a rapid increase in bedridden elderly, due to cerebral strokes and other diseases, has become a social problem due to soaring medical costs and heavy burden of long term care support. Therefore, development of walk rehabilitation devices for the elderly, suffered from cerebral strokes, is strongly expected. In the research so far, the authors have developed a rollator with a chest support pad that can rotate freely with one degree of freedom, and the effectiveness of its walk assistance was evaluated. In this study, a novel rollator using a motor-driven chest support pad was developed. A compact system to combine data collect system and motor control was configured. Walk measurements for six subjects were conducted using the developed rollator. The relationship between the movements of the lower limbs and rotation of the motor driven chest support pad was investigated. Time series and power spectrum results were analyzed, and the effectiveness of the motor-driven chest support pad on movement of the lower limb during walking was discussed.
