The invention discloses a training and motion state detection integrated ankle rehabilitation training device. The device comprises a supporting mechanism, a training mechanism and a detection portion; the supporting mechanism comprises a base, a supporting frame, foot plates and foot plate supporting seats; the training mechanism comprises varus/valgus motion platforms, dorsiflexion/plantarflexion motion platforms and pronation/supination motion platforms; the detection portion comprises three torque sensors mounted on single platforms and three encoders mounted on motors for power transmission. The training and motion state detection integrated ankle rehabilitation training device can realize three-degree-of-freedom rehabilitation training of human ankles, can be used for providing passive training for patents by simulation of operation techniques of therapists and is also available for independent training of the patents under specified requirements of doctors; by the torque sensors and the encoders, torque and movement position information of the patients in a training process can be acquired, functions of rehabilitation training and patient's movement information detection are integrated, and bases can be provided for a rehabilitation evaluation system.
