A deltoid strain is pain at the front, side or back of the shoulder. The deltoid muscle covers the joint of the shoulder. It is divided into three parts which are the anterior, the middle part and the back part. The deltoid muscles facilitate the abduction of the arm such as moving the arms to the side of the body and elevating the arms in front of the body. It is a powerful muscle and needed for various sports activities. Due to certain activities this muscle can become overused and injured and result to straining the deltoid.
- Grade 1 deltoid strain – mild pain in the shoulders, and capable of using the shoulder for activities without difficulty or pain.
- Grade 2 deltoid strain – partial rupture of the muscle, severe shoulder pain, limited movement of the shoulder and swelling of the affected area.
- Grade 3 – severe form of strain, complete rupture of the muscle, severe and incapable of using the shoulders for various activities.
