Ergonomic design enables full flexion and extension of the wrist joint, along with radial and ulnar bending exercises to improve range of motion and allow bilateral hand exercise. Features two training modes: switch between pronation and supination for active training and fast recovery, or use passive training where the healthy hand assists the affected hand to encourage movement and alleviate elbow stiffness. Aids in upper limb rehabilitation by enhancing range of motion in shoulder and elbow joints, effectively strengthening upper body muscles to support overall recovery. Enhances wrist joint flexibility through forward and reverse training, addressing issues related to upper limb pronation and supination to gradually restore hand function. Ideal for wrist rehabilitation and muscle strength training, suitable for individuals with ligament injuries, hand hemiplegia, dysfunction, stiffness, or weakness to increase wrist joint range of motion.
