In the study, researchers had twenty women wear two pairs of shoes with three inch heels, one with a narrow heel and the other with a thick one. The scientists compared how much pressure was put on the women's knees by both types of shoes. The women also walked barefoot to test normal pressure. The scientists found that both types of shoes applied equal amounts of pressure to the knees. Compared with walking barefoot, the heels increased pressure on the inside of the knee by 26 percent. Increased pressure on the knee eventually leads to arthritis, experts say.
The idea that high heels are bad for your health isn't new—scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained(扭伤)ankles and back problems. But in 1998,Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage(软骨) surrounding the knee. The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky highheeled shoes she noticed many women wearing. ”This study confirms what we all intuitively(直觉地)know that highheeled shoes of any kind are not good for our health,” said Dr.Glem Pfeffer, a San Francisco doctor and member of the American Academy of Orthopedic Surgeons who was not connected to the study.
