"In 2006, a group of rheumatologists at Chicago's Rush Medical College studied the force of the "knee adduction moment"—basically, the force of torque on the medial chamber of the knee joint where arthritis occurs. For years, rheumatologists have advised patients with osteoarthritis of the knees to wear padded walking shoes, to reduce stress on their joints. As for the knee-adduction moment, they've attempted to address it with braces and orthotics that immobilize the knee, but with inconsistent results. So the researchers at Rush tried something different: They had people walk in their walking shoes, then barefoot, and each time measured the stress on their knees. They found, to their surprise, that the impact on the knees was 12 percent less when people walked barefoot than it was when people wore the padded shoes." <snip> -- Please read our new blog at: http://blog.prathambooks.org/ Join our Facebook Page too: http://www.facebook.com/pages/Pratham-Books/9307274926
