Featuring intelligence, safety, and efficiency, it allows patients to easily, happily, and independently complete finger function training with minimal supervision from a therapist. DA detachable, wearable, and adjustable structure adopts a single-tube adjustable design with individual finger-wear components. It integrates mirror therapy + synergistic stimulation + bilateral movement.Each finger can be worn individually and adjusted separately (including fit adaptability, range of motion flexion-extension amplitude, and flexion-extension force). In a single hand opening and closing motion, the five fingers can achieve different movement postures and forces to address various complex conditions. This enables simultaneous training of five fingers with five different conditions in one action.
