At the international academic conference (Vladivostok), I gave a history of Teikyo Heisei University and a report on the gait analysis research of the ankle assist device CoCoroeAAD to date. Russia has a lot of physical therapy and a high interest in robots. The ankle assist device CoCoroeAAD is effective before and after use, but the experience of the physical therapist is important because the setting of the device is left to the physical therapist.
