The rhomboid major muscle is a skeletal muscle located in the upper back. It is a broad, thin muscle that runs from the spine to the inner border of the scapula (shoulder blade). It is responsible for pulling the scapula towards the spine and rotating it downward. This action helps to stabilize the shoulder blade and support the shoulder joint.
The rhomboid major muscle is located beneath the trapezius muscle, which is a large, triangular muscle that covers much of the upper back and neck. The rhomboid minor muscle, a smaller muscle that lies beneath the rhomboid major, also assists in these actions. Together, the rhomboid major and minor muscles help to maintain proper posture and support the shoulder joint during movement.
Injuries to the rhomboid major muscle can cause pain and weakness in the upper back and shoulder area. Common causes of injury include strain from lifting heavy objects, poor posture, and overuse. Treatment may include rest, ice, physical therapy, and in severe cases, surgery.
Function of the Rhomboid Major Muscle
The main function of the rhomboid major muscle is to pull the scapula towards the spine and rotate it downward. This action is known as scapular retraction and helps to stabilize the shoulder blade and support the shoulder joint.
The rhomboid major muscle works in conjunction with the rhomboid minor muscle and the trapezius muscle to perform these actions. The trapezius muscle, which covers much of the upper back and neck, helps to elevate and rotate the scapula. Together, these muscles help to maintain proper posture and support the shoulder joint during movement.
In addition to its role in posture and shoulder stability, the rhomboid major muscle also plays a role in arm movement. It assists in moving the arm backwards and upwards, such as when reaching for an object above the head.

Common Issues with a Rhomboid Major Muscle
The most common issue with the rhomboid major muscle is strain or injury. This can occur due to overuse, lifting heavy objects, or poor posture. Symptoms of a strained or injured rhomboid major muscle may include:
- Pain: A strained or injured rhomboid major muscle may cause pain in the upper back and shoulder area. This pain may be sharp or dull, and may be worse when moving the arm or shoulder.
- Weakness: An injured rhomboid major muscle may cause weakness in the upper back and shoulder area. This may make it difficult to lift or move the arm, or to maintain proper posture.
- Limited range of motion: A strained or injured rhomboid major muscle may cause limited range of motion in the shoulder and arm. This may make it difficult to move the arm backwards or upwards, or to reach for objects above the head.
- Swelling: In some cases, a strained or injured rhomboid major muscle may cause swelling in the upper back and shoulder area.
If you experience any of these symptoms, it is important to see a healthcare professional for proper diagnosis and treatment. Treatment may include rest, ice, physical therapy, and in severe cases, surgery.
How to stretch your Rhomboid Major Muscle
Here are a few stretches that can help to stretch the rhomboid major muscle:
- Doorway stretch: Stand in a doorway with your arms extended to the sides and your palms flat against the door frame. Step forward with one foot, keeping your arms extended. You should feel a stretch in your upper back and shoulders. Hold the stretch for 20-30 seconds, then switch sides and repeat.
- Chest stretch: Stand with your feet shoulder-width apart and your arms extended behind you, palms facing away from your body. Reach back and clasp your hands together. Lift your arms up and back, stretching your chest and upper back. Hold the stretch for 20-30 seconds, then release.
- Shoulder blade squeeze: Stand with your feet shoulder-width apart and your arms relaxed at your sides. Gently squeeze your shoulder blades together, as if you were trying to touch them in the middle of your back. Hold the squeeze for 5-10 seconds, then release. Repeat the squeeze 10-15 times.
It is important to stretch gently and avoid overstretching, which can cause injury. Stop the stretch if you feel any pain, and consult a healthcare professional if you have any concerns about your stretching routine.
How to Rehab your Rhomboid Major Muscle
If you have injured your rhomboid major muscle or are experiencing pain or weakness in the upper back and shoulder area, it is important to seek medical attention to determine the cause of the issue and develop a treatment plan. A healthcare professional may recommend the following steps to rehab your rhomboid major muscle:
- Rest: Resting the muscle can help to reduce inflammation and allow it to heal. Avoid activities that may cause further strain on the muscle, such as lifting heavy objects or participating in intense exercise.
- Ice: Applying ice to the affected area can help to reduce inflammation and numb pain. Apply ice for 15-20 minutes at a time, several times a day, for the first 48-72 hours after the injury.
- Physical therapy: A physical therapist can develop a rehabilitation program that may include stretches, exercises, and other techniques to strengthen and stretch the muscle.
- Medications: A healthcare professional may prescribe medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), to reduce inflammation and pain.
- Surgery: In severe cases, surgery may be necessary to repair the muscle.
It is important to follow the treatment plan recommended by your healthcare professional to properly rehab your rhomboid major muscle and reduce the risk of further injury.
