Short summary
This paper presents a novel rehabilitation mechanism for patients with unilateral motor deficits. Its core principle is "the sound side drives the affected side", using a single-degree-of-freedom mechanical system where the patient's healthy limbs power the movement of their impaired ones. The device consists of an eight-bar leg mechanism, a six-bar arm mechanism, and a back transmission system to ensure coordinated contralateral motion. Design validity was confirmed via simulation and a prototype.
