Functional features: With the help of rib bars, the range of motion and muscle strength training of upper and lower limb joints, sitting and standing training, balance training and trunk stretching training are carried out. Gradually increase the range of motion of the shoulder joint by moving the fingers up the ladder to relieve pain. Rib wood (including pendant) Specification: 80 * 580 * 2310 cm Function: Corrects the posture, prevents the deformity, may do the muscle strength endurance, the joint range of motion training. Shoulder ladder The shoulder ladder is a device that trains the range of motion of the shoulder joint by climbing a specific height with the fingers. Structural composition: 1. Ladder teeth-wood or steel 2. Skeleton-steel or wood 3. Coupling adjustment device-steel or wood Structural parameters: ladder tooth length: 9cm Height difference between upper and lower teeth: 80 ~ 120cm Front and back distance of upper and lower teeth: 50 ~ 60cm Height of lower teeth from the ground: 80cm Height adjustment range: 0 ~ 40cm Performance requirements: It is generally required to have a device that can be connected with the rib, and the horizontal angle can be adjusted, that is, the skeleton can rotate around the vertical axis. Adjustable mounting height. Purpose: Shoulder range of motion training. For patients with limited shoulder joint movement due to central motor paralysis such as peripheral nerve paralysis or hemiplegia, shoulder ladder can be used to lift shoulder joint to prevent shoulder joint contracture.
