Abstract: A wrist joint actuating structure of a hand rehabilitation device includes a palm orthosis body, a forearm orthosis body and a joint unit. The palm orthosis body includes a plurality of finger support rods and a thumb support rod. The joint unit is a universal joint and is connected between the palm orthosis body and the forearm orthosis body. The palm orthosis body can be turned an angle relative to the forearm orthosis body through actuation of the joint unit according to the bending degree of a user's wrist joint. A tension adjustment unit includes elastic members connected to the finger support rods and the thumb support rod. According to the different stretching tensions required by the fingers or the thumb for rehabilitation, the respective lengths of the other ends of the elastic members to be pressed by a fixing seat are adjustable, so as to adjust different stretching tensions.

Abstract: A tension adjustment structure of a hand rehabilitation device includes a palm orthosis body, a forearm orthosis body, and a tension adjustment unit. The palm orthosis body includes a plurality of finger support rods and a thumb support rod. The forearm orthosis body includes a fixing seat. The tension adjustment unit includes a plurality of elastic members. First ends of the elastic members are connected to the finger support rods and the thumb support rod, respectively. Second ends of the elastic members are connected to the fixing seat. The elastic members are adjustable to generate different stretching tensions by adjusting respective lengths of the second ends of the elastic members to be secured to the fixing seat.

Abstract: A foot assistive device for improving drop foot gait comprises an assistive device body and an elastic module. The assistive device body comprises a foot support base and a brace. The foot support base is movably connected to the brace. The elastic module connects the foot support base to the brace. The elastic module has a spring, a preset support included angle is formed between the foot support base and the brace under an elastic force of the spring. The support included angle is not larger than 90°. Thereby, when the foot is raised up, the foot support base is unlikely to drop excessively due to the foot weight, the drop foot gait is improved effectively.
