We examined changes to the level of care needed by the patients who have been rehabilitated by the Takizawa method over an extended period of time. Although it was reported that approximately 29% of elderly needing some level of care in Japan got worse within two years, aggravation was seen less with this method. Then, in order to investigate a mechanism, we performed cerebral function evaluation by the functional Near-Infrared Spectroscopy. The Shimadzu Company offered the Near-Infrared Spectroscopy and analysis software; we analysed not only the motivative exercise for the ankle joint dorsiflexion and plantar flexion exercise, but also resistive selfexercise facilitated by using the device and passive exercise supervised by the physiotherapist. It was found that the motivative exercise on an ankle activated the cerebral function more than the passive exercise [P<0.05] and the motivative exercise and resistive self-exercise had no significant difference.
