Patent attributes
An auxiliary device for muscle strength training is provided, which includes: a base; a sliding member slidingly coupled to the base; and a connecting-rod mechanism connected to the base and the sliding member in such a way that a positional shift of the sliding member allows the connecting-rod mechanism to rotate relative to the base and change its state. As such, the auxiliary device has first and second configurations to assist patients who are incapable of controlling their muscles by themselves to effectively train specific muscle groups. Further, elastic members are connected to the base and the connecting-rod mechanism and provide elastic potential energies so as to keep the auxiliary device in static equilibrium. The auxiliary device has a simple structure and is easily manufactured at a low cost and applicable for patients with muscle strength lower than grade 3.
