An old work of 18 years, children's torticollis rehabilitation medical treatment, is suitable for children from 6 months to 10 years old. There are not many pictures. From design to landing, several versions have been changed in the middle. The main body is made of silicone, and the nylon pillar is supported at three points, which is wear-resistant and pressure-resistant. By pressing both sides of the knob, adjusting the height by rotation and releasing the clamping position, the pillar is easy to install and disassemble, and the position can be adjusted at will.
