What is a Teres Minor Muscle

The teres minor muscle is a small, thin muscle located in the shoulder region of the human body. It is one of several muscles that make up the rotator cuff, a group of muscles and tendons that surround the shoulder joint and help to stabilize and move the shoulder.

The teres minor muscle originates from the back of the shoulder blade (scapula) and inserts into the upper part of the arm bone (humerus). It acts to rotate the arm outward (i.e., abduct the arm) and also assists with shoulder extension and downward rotation.

Injury to the teres minor muscle, or to any of the other muscles in the rotator cuff, can cause pain and limited range of motion in the shoulder joint. Treatment may include physical therapy, pain medication, and in some cases, surgery.

Function of the Teres Minor Muscle

The primary function of the teres minor muscle is to rotate the arm outward (i.e., abduct the arm). This movement is important for activities such as reaching overhead or behind the back.

The teres minor muscle also assists with shoulder extension and downward rotation. Shoulder extension is the movement of the arm away from the body, while downward rotation is the movement of the arm downward and toward the body. These movements are important for activities such as lifting objects or throwing a ball.

In addition to these specific movements, the teres minor muscle helps to stabilize the shoulder joint and prevent excessive movement or instability. It works together with the other muscles of the rotator cuff to provide support and stability to the shoulder joint.

Injury or weakness in the teres minor muscle can lead to pain and limited range of motion in the shoulder joint. It is important to maintain strength and flexibility in this muscle and the other muscles of the rotator cuff to help prevent injury and maintain proper shoulder function.

Common Issues with a Teres Minor Muscle

There are several common issues that can affect the teres minor muscle, including:

  1. Strains or tears: Like any muscle, the teres minor muscle can be strained or torn if it is overused or subjected to sudden, intense forces. This can result in pain, swelling, and difficulty using the shoulder.
  2. Tendinitis: Tendinitis is an inflammation of the tendons, which can be caused by overuse or repetitive stress. The teres minor muscle has a tendon that can be affected by tendinitis, leading to pain and limited range of motion in the shoulder.
  3. Bursitis: Bursitis is an inflammation of the bursae, small fluid-filled sacs that cushion and protect the muscles and tendons around a joint. The teres minor muscle has a bursa that can become inflamed, leading to pain and swelling in the shoulder.
  4. Rotator cuff injuries: The teres minor muscle is part of the rotator cuff, which is a group of muscles and tendons that surround the shoulder joint. Injuries to the rotator cuff can affect the teres minor muscle and cause pain and limited range of motion in the shoulder.
  5. Shoulder impingement syndrome: Shoulder impingement syndrome is a condition in which the tendons or bursae of the shoulder become compressed or pinched, leading to pain and limited range of motion. The teres minor muscle and its tendon can be affected by shoulder impingement syndrome.

Treatment for issues affecting the teres minor muscle may include rest, physical therapy, pain medication, and in some cases, surgery. It is important to see a healthcare provider for an accurate diagnosis and appropriate treatment plan.

How to stretch your Teres Minor Muscle

Here is a simple stretch that can help to stretch the teres minor muscle:

  1. Stand with your feet shoulder-width apart and your arms at your sides.
  2. Lift your left arm up and out to the side until it is parallel to the ground.
  3. Bend your elbow so that your hand is behind your head.
  4. Use your right hand to gently push your left elbow downward and toward your left hip.
  5. Hold the stretch for 15-30 seconds and then release.
  6. Repeat the stretch on the other side.

It is important to stretch both sides evenly to maintain balance in the muscles of the shoulder.

Remember to stretch slowly and gently, and never force your body into a position that feels painful or uncomfortable. If you experience any pain while stretching, stop immediately and consult a healthcare provider.

In addition to stretching, it is important to maintain overall shoulder strength and flexibility to help prevent injury and maintain proper shoulder function. This can be achieved through a combination of stretching and strengthening exercises. Consult with a healthcare provider or a fitness professional to develop a safe and effective exercise plan.

How to Rehab your Teres Minor Muscle

Rehabilitation of the teres minor muscle may be necessary if the muscle has been injured or weakened. Here are some general steps that may be taken to rehab the teres minor muscle:

  1. Rest: After an injury, it is important to allow the muscle time to heal. Resting the muscle can help to reduce inflammation and pain.
  2. Ice: Applying ice to the affected area can help to reduce swelling and inflammation.
  3. Physical therapy: Physical therapy can be helpful in strengthening the muscle and improving range of motion. A physical therapist can design a personalized exercise program to help you regain strength and flexibility in the muscle.
  4. Stretching: Stretching the muscle can help to improve flexibility and reduce the risk of future injuries.
  5. Strengthening exercises: Strengthening exercises can help to rebuild strength and stability in the muscle. These may include exercises such as shoulder rotations or internal and external rotation exercises.
  6. Gradually return to activities: It is important to gradually increase the intensity and frequency of activities to avoid re-injury. A physical therapist can help you to progress safely and effectively.

It is important to follow the guidance of a healthcare provider or physical therapist when rehabbing the teres minor muscle. They can provide personalized treatment recommendations based on your specific needs and goals.
