Zhang Chengyu stands all day sweeping, mopping, cleaning windows, cooking, washing dishes, collecting clothes, hanging clothes, and doing housework, which can easily overload the hip joints and cause pain. Over time, it may continue to deteriorate, greatly limiting mobility, and even causing degenerative hip arthritis. In the worst case, artificial joint replacement may be required. A Japanese dean suggested that by setting up a chair, it might be possible to prevent hip joint pain from getting worse! Standing for long periods of time while doing housework can easily cause hip pain. Hiroshi Katsuno, director of Japan's HIRO Plastic Surgery Clinic, said that many housework needs to be done while standing, such as cooking and preparing food, cooking, washing dishes, sweeping and mopping the floor, etc. Although there are many modern household appliances such as washing machines and vacuum cleaners that can slightly reduce the burden, it is still impossible to completely get rid of the nightmare of standing for long periods of time. Especially when washing dishes and cooking, the body will lean forward slightly, which puts a heavier burden on the hip joints. This has become one of the main causes of hip pain among housewives. Hiroshi Katsuno emphasized that hip pain is closely related to lifestyle habits that overburden and overuse the hip joint. If not improved, it may worsen, causing the range of motion of the hip joint to gradually decrease, making the body's balance even worse. , may cause difficulty in movement, and may even lead to inflammation and degenerative arthritis. Dr. Motomi Ishibe, a hip joint expert who performs more than 600 hip surgeries a year in Japan, also said that hip joint wear can range from mild pain to serious problems that can even cause huge troubles in life. The scope of the impact includes the speed of crossing the road, or Press the accelerator, brake, etc. while driving. Taiwan Elite Clinic Health Education Information also pointed out that aging and external injuries may also cause degenerative hip arthritis. In addition to pain when walking, causing lameness, in severe cases, it may even hurt when sleeping and resting. If no improvement is made, eventually The only treatment is probably artificial joint replacement. Hiroshi Katsuno said that there is actually a simple way to prevent the deterioration of hip joints. Just put a commercially available folding high chair in the kitchen for daily use when cooking and washing dishes. The seat height of the chair is about 60 centimeters, which allows your knees to bend slightly, but be careful not to choose a chair with wheels, and the chair must be stable enough to avoid falling. In addition to sitting on a chair when washing dishes, Hiroshi Katsuno also pointed out that the key to preventing knee joint pain from worsening is the normal bending angle of the hip joint, which is best kept within 70 to 90 degrees. He suggested that the seat surface of the chair you usually sit on should be at least 50cm from the floor, so that the hip joint bending angle does not exceed 90 degrees, which is very helpful in reducing the burden on the hip joint.
