How to treat Sprain and Strain injuries
A sprain is an injury to a ligament. A ligament is a thick, tough, fibrous tissue that connects bones together. Commonly injured ligaments are in the ankle, knee, and wrist. The ligaments can be injured by being stretched too far from their normal position. The purpose of having ligaments is to hold your skeleton together in a normal alignment — ligaments prevent abnormal movements. However, when too much force is applied to a ligament, such as in a fall, the ligaments can be stretched or torn; this injury is called a sprain.A strain is an injury to a muscle or tendon. Muscles move your skeleton in an amazing variety of ways. When a muscle contracts, it pulls on a tendon, which is in turn connected to your bone. Muscles are made to stretch, but if stretched too far, or if stretched while contracting, an injury called a strain my result. A strain can either be a stretching or tear of the muscle or tendon
Causes of Sprains and Strains
A sprain is caused by a ligament being stretched too far. Ligaments are very strong and can allow a joint to move, but they do not have much elasticity. That means that when the ligament is stretched too far, tears can occur. A ligament tear can be partial or complete. Typically, physicians will indicate the severity of the injury by grading the ligament damage. Grade 1 and grade 2 injuries are usually partial injuries to the ligament, whereas a grade 3 injury is often a complete tear.
Strains are injuries to muscles or the tendons that attach the muscles to your bones. By pulling too far on a muscle, or by pulling a muscle in one direction while it is contracting (called an 'eccentric contraction') in the other direction can cause injuries within the muscle or tendon. Strains can also be caused by chronic activities that develop an overstretching of the muscle fibers.
