![]() The ACL connects the thigh bone to the shin bone. Timothy Hewett, head of sports medicine research at Ohio State University, has long studied a part of the knee joint known as the ACL (or anterior cruciate ligament Tough, flexible tissue that connects bones to each other and holds your skeleton together.). ![]() ![]() Any movements outside a joint’s natural range might cause injury.ĭr. But others, like your knee joint, can only bend one way. Some joints, such as your shoulder joint, can move in many directions. Joints are a common source of problems and pain. Others have devised improved treatments for movement disorders such as cerebral palsy and Parkinson’s disease. Some researchers are working to develop better artificial joints. NIH-funded studies of biomechanics have already led to better ways to prevent muscle and joint injuries in kids during sports and play, and to help older people stay more mobile and independent. These parts all work together to help you move throughout the day. Your body has about 200 bones and more than 600 muscles. The main moving parts of your body include the solid bones, the joint tissues that link bones together, and the muscles that attach to your bones. “Biomechanics is effectively applying the physics of mechanics to problems in biology and medicine,” Weiss says. Body movements involve force, balance, gravity and motion. Jeffrey Weiss, a biomechanics expert at the University of Utah. “All systems, whether in traditional mechanics or in the human body, are governed by the same basic physical laws,” says Dr. These studies are finding that the way you move-including walking, standing and bending-can affect your future mobility and overall health. This type of research is called biomechanics. Scientists are studying the mechanical movements of our bodies to help us be as strong, flexible and mobile as possible throughout our lives. It needs regular care and maintenance to keep moving with ease. Like any machine, your body can suffer some wear and tear. Your bones, muscles and joints all work together to make your body an amazingly movable machine. Think about all the movements you do every day: walking, climbing stairs, typing, turning doorknobs and lifting.
