The invention provides an intelligent apparatus with functions of activating tendon and collaterals. The intelligent apparatus is characterized by comprising a bracket structure, a leg part supporting structure, a hip part supporting structure, an upper body part supporting structure and a controller, wherein one side of the hip part supporting structure is connected with the leg part supporting structure through the bracket structure; and the other side of the hip part supporting structure is connected with the upper body part supporting structure through the bracket structure. According to the intelligent apparatus, a clinostatism tendon stretching method is adopted, so that a gravity action direction and massaging warm-up before tendon stretching are changed, and effects of reliving pain feeling, improving training strength conveniently, and improving physical therapy and treatment effects are achieved; the bending, stretching and lifting speeds of the apparatus are inversely proportional to the tendon stretching strength under control of an intelligent algorithm, so that force increasing can be executed step by step; the intelligent apparatus also has a force detection sensor, and hand and foot-triggered emergency stop protection, so that injury to a user can be avoided; on the basis of full automation, the intelligent apparatus also has a sound-control operating system, so that action patterns, strengths, time and the like can be chosen at any time; and furthermore, the intelligent apparatus has the functions of user favor memory and score evaluation so as to improve interest of the user.
