A strain / sprain can refer to an injury caused by damage to one or more of the structures located in the joints of the human body. When the damage is done to a muscle or tendon, the resulting injury is referred to as a strain. If a ligament is involved, the injury is referred to as a sprain. Typical symptoms of these injuries are pain, swelling, inflammation, tenderness, inability in some cases to use the joint for normal purposes and (in severe cases) a feeling of “instability” in the joint. An orthopedic brace can be used to restrict the movement of the damaged structures and so give them time to heal. Care should be taken to consult with a medical professional in the choice of a brace in order to ensure that the choice is suited to the individual’s specific circumstances, including his or her normal activity level.
