1, don't move too fast, don't run and jump on the stairs. When climbing stairs, pay attention to the strength of thigh muscles, hip muscles and abdominal muscles. At the same time, your arm should also play an important role. When you feel tired, you can hold the handrail of the stairs to help lift your body upwards and reduce the burden on your thighs.

2. Because going downstairs is more harmful to the knee joint than climbing stairs, it is best to lean sideways or hold the handrail with both hands when going downstairs.

3. Climb stairs with a portable cross-country walking stick, and be careful not to carry or lift heavy objects.
