Shoulder injuries are likely to occur if the arms are overly stretched. It is important to note that the muscles, tendons and ligaments might be lengthened beyond the normal range of motion, thus resulting to instability of the joint.
The instability heightens the risk for shoulder injuries such as sprains, strains and dislocations. If an injury occurs, a doctor should be consulted for medical treatment.
Who are at risk?
Athletes who are susceptible to overstretching and the ensuing shoulder injuries include gymnasts and baseball pitchers. The types of sports that makes athletes susceptible to acute overstretching of the arms from a fall, tackle or reach include volleyball, football and baseball.
Those who engage in yoga who perform positions incorrectly might overly stretch the arms and end up with shoulder injuries.
Common forms of shoulder injuries
It is important to note that overly stretched muscles deactivate and lose their ability to normally contract, thus resulting to diminished joint stability.
The overstretched ligaments that link and stabilize the shoulder bones also lead to instability. A decrease in the arm muscle activation as well as stabilization of the ligament also heightens the possibility for injuries.
Tendon and muscle strains
If the arm is overstretched, the muscles neighboring the shoulder becomes strained or pulled, resulting to a torn muscle. The tendon in which the muscle links might also overstretch and strain. A muscle or tendon strain might be partial or full.
The ligaments that link the bones comprising the shoulder joint are rigid. Overstretching the shoulder joint and arm can occur from a fall or when reaching for a ball.
Subluxations and dislocations
Overstretching of the ligaments and muscles adjacent the shoulder joint increases the risk for subluxation or dislocation.
A dislocation occurs if the joint moves out of the socket and should be reduced or restored back manually. A subluxation occurs if the joint moves back into the socket naturally. Both shoulder injuries overstretch the ligaments, further escalating the possibility for future injuries to the joint.
