A system for muscle, tendon and spine adjustment and rehabilitation training, a robot (820, 1000), and a holding device (300) thereof. The robot comprises: a base (100), a back plate (200), the holding device and a first drive mechanism (400). The back plate is arranged on the base and rotatably connected to the base. The holding device is arranged on the back plate, forms a holding area (302) with the back plate, and is used for holding the upper half of the body of a user (888) within the holding area when the user leans against the back plate. The holding device is hingedly connected to the back plate to enable the holding device to open or close on one side of the formed holding area with respect to the back plate, so as to make it easy for the user to enter or leave the holding area. The first drive mechanism is used for driving the back plate to rotate with respect to the base when the holding device holds the upper half of the body of the user. The robot has a simple structure, and simultaneously performs adjustment or training on the muscles, tendons and entire spine of the user. The horizontally opening holding arm structure makes it easy for the user to enter and exit the holding area.Font lobjet de cette invention un système de réhabilitation et de régulation des tendons de la colonne vertébrale, un robot (820, 1000) et un dispositif denveloppement et étirement (300) associé, lequel robot comprend une base (100), un plateau (200), un dispositif denveloppement et étirement et une première structure de transmission (400).
