The invention discloses a wearable multifunctional cervical vertebra rehabilitation power exoskeleton, and relates to the field of human-computer interaction rehabilitation assistive devices. The wearable multifunctional cervical vertebra rehabilitation power exoskeleton comprises an active driving motor module, a fixed support module and a movable joint assembly, wherein the active driving motormodule is connected with the fixed support module, the active driving motor module comprises a left shoulder push rod motor, a right shoulder push rod motor, a cervical vertebra and thoracic vertebraleft front side push rod motor, a cervical vertebra and thoracic vertebra left rear side push rod motor, a cervical vertebra and thoracic vertebra right front side push rod motor and a cervical vertebra and thoracic vertebra right rear side push rod motor, and the active driving motor module and the movable joint assembly are combined into a six-link power driving structure. By means of the implementation of the wearable multifunctional cervical vertebra rehabilitation power exoskeleton, four-degree-of-freedom rehabilitation exercises of passive traction, anteflexion and posterior extension, lateral flexion and horizontal rotation of the cervical vertebra are achieved, traction training of the neck and directional resistance training of neck muscles are conducted, the neck muscle strengthis improved, the stability of the cervical vertebra is enhanced, and the biomechanical balance of the cervical vertebra is improved and corrected.
