For high performance, it is important that the myoelectric prosthetic hand have an active wrist mechanism. However, the wrist mechanism can be damaged by external forces during wrist dorsiflexion. Here, we describe a dorsiflexion passive mechanism designed to prevent damage to the wrist mechanism and stabilize the posture of the myoelectric prosthetic hand. When the wrist mechanism reaches the limit of dorsiflexion, the gears become passive, allowing the hand in contact with the elastic body to move elastically against external forces. This is the mechanism of the dorsiflexion passive mechanism.
