Causes of Sprains and Strains
A sprain is usually caused by trauma to a joint (the space between bones). Twisting or forces overstretch the ligaments (such as hyperextension or hyperflexion) and can cause tears in the ligament tissue, which can be graded from mild to severe depending on the amount of damage. Sprains can happen when people twist an ankle or knee or fall on an elbow or shoulder. A strain is usually the result of overstretching or overuse of muscles and tendons. An acute strain can be the result of sudden twisting or trauma to the muscles or tendons. Chronic strains are the consequence of overuse of muscles and tendons, such as with athletes who train constantly and do not rest adequately.
