Tendon a decrease in the average thickness of the collagen fiber bundles comprising the tendon. In humans, an experiment in which people were subjected to a simulated micro-gravity environment found that tendon stiffness decreased significantly, even when subjects were required to perform restiveness exercises. These effects have implications in areas ranging from treatment of bedridden patients to the design of more effective exercises for astronauts. The tendons in the foot are highly complex and intricate. Therefore, the healing process for a broken tendon is long and painful. Most people who do not receive medical attention within the first 48 hours of
Achilles tendon rupture opinions are divided what is to be preferred. Non-surgical management traditionally was selected for minor ruptures, less active patients, and those with medical conditions that prevent them from undergoing surgery. It traditionally consisted of restriction in a plaster cast for six to eight weeks with the foot pointed downwards (to oppose the ends of the ruptured tendon). But recent studies have produced superior results with much more rapid rehabilitation in fixed or hinged boots. Some surgeons feel an early surgical repair of the tendon is beneficial. The surgical option was long thought to offer a significantly smaller risk of "re-rupture"
