【The most knee-friendly up and down stair posture】 >> when going up the stairs, the back is straight, the center of gravity should not be prematurely moved forward, and the knee joint flexion angle should be appropriately reduced; the full foot is on the ground; avoid the inner and outer figure eight feet, and it is best to align the second toe with the knee. Premature shift of the center of gravity leads to greater pressure between the patella and femur. When climbing the stairs, only the front foot is used to land on the ground, the lower leg is equivalent to the distal end is not fully fixed, and the ankle joint is easily damaged. The inner or outer figure eight can cause the physiological line of the lower limb to be incorrect, and the trajectory of the patella sliding on the femur is affected, which can cause joint injury. When >> go downstairs, in order to prevent the knee joint from being under pressure, it is necessary to use the forefoot to land first, and then transition to the full foot landing to cushion the pressure of the knee joint. After climbing the stairs, a local massage of the knee joint can be performed. The old man can go up and down the stairs, and he can lean on his side and hold the handrail of the stairs with both hands. Let the toes touch the ground first, so that the arch of the foot is subjected to a part of the force, which can increase the buffer distance and play a certain protective role on the knee joint.
