The biomechanics of walking and running.

An increased knowledge of the biomechanics of normal walking and running will improve our understanding of the possible mechanisms of pathology and ultimately improve the treatment of pathology and injury. Running, a natural extension of walking, involves increased velocities, joint range of motion, forces, muscle activity, joint moments, and joint powers as compared with walking. These differences not only stress the mechanics of the body to a greater extent but also contribute to the development of injury due to overuse. With the use of modern computerized gait analysis techniques that provide objective information, comprehension of normal and also pathologic walking and running patterns can be improved.
