How to climb stairs correctly?

1, when going up the stairs

When climbing stairs, the back should be kept straight, and the center of gravity should not move forward prematurely, otherwise it will increase the pressure between the patella and cartilage; Reduce the knee flexion angle, if the flexion angle is too large, it is easy to damage the knee joint; The whole sole of the foot should be on the ground, but the forefoot should be on the ground, which will not play a fixed role, reduce the efficiency of stretching the knee and hip, and will also damage the ankle joint. Avoid splayed feet inside and outside, otherwise the physiological force line of lower limbs will be incorrect, which will affect the sliding of patella on femur and lead to joint injury. When climbing stairs, it is advisable to aim your second toe at your knees.

In order to reduce the pressure on the knee joint, first land with the forefoot, then the center of the foot and finally the heel, which can cushion the pressure on the knee joint. Massage your knees properly after climbing stairs every time can improve local blood circulation. When the elderly go up and down the stairs, they should try to lean sideways. They must hold the handrail with their hands and let their toes land first, which can extend the buffer distance and better protect the knee joint. Older people who suffer from joint diseases and are over 70 years old should go up the stairs slowly, make sure that their feet stand firm before going down the stairs, and don't worry to avoid falling.
