The subscapularis is a powerful muscle located in the shoulder joint. It plays an important role in shoulder movement and stability. However, due to its location and anatomy, it can be prone to overuse injuries and trauma-related conditions, which can lead to pain and reduced range of motion. This guide aims to provide an overview of the subscapularis muscle, importance of addressing subscapularis pain and its associated conditions, as well as the available treatments, recovery timeline, and self-management strategies.
Overview of the Subscapularis Muscle
The subscapularis is located in the shoulder joint underneath the scapula on either side of the body. It connects to both sides of the front surface of the humerus and is responsible for internal rotation of the shoulder, which allows your arms to move inwards. It also assists in adduction (pulling the arm towards your body), extension (lifting the arm up away from your body), and abduction (moving your arm outward).
Importance of Addressing Subscapularis Pain
Subscapularis pain is the result of injury or overuse of the muscle. If left untreated, it can cause chronic stiffness and reduced range of motion in the shoulder, leading to greater disability and decreased quality of life. It’s important to seek treatment as soon as possible to prevent further damage and ensure a full recovery.

Anatomy of the Subscapularis Muscle
Location and Attachment Points
The subscapularis muscle is located in the shoulder joint underneath the scapula on either side of the body. It attaches medially to the lesser tubercle of the humerus, and laterally to both sides of the anterior surface of the scapula. This helps it produce internal rotation and adduction of the shoulder.
Function and Role in Shoulder Movement
The primary function of the subscapularis muscle is to power internal rotation of the shoulder, which allows your arms to move inwards. It also aids in adduction (pulling the arm towards your body), extension (lifting the arm up away from your body), and abduction (moving your arm outward).
Common Injuries and Conditions
The most common injury associated with the subscapularis muscle is rotator cuff tendinitis, which occurs when the tendon becomes swollen, inflamed, or frayed due to repetitive use or trauma. Other conditions that may lead to subscapularis pain include bursitis, impingement syndrome, and a tear of the subscapularis muscle or tendon.

Causes of Subscapularis Pain
1) Overuse and Repetitive Strain
Repetitive use of your shoulder can cause muscles such as the subscapularis to become strained, leading to pain and stiffness. This is often seen in athletes, musicians, and manual laborers who use their shoulders extensively. It can also be caused by poor posture or improper technique when performing activities that involve shoulder movement.
2) Trauma and Injuries
Direct trauma to the subscapularis muscle or its tendon can cause tearing resulting in pain and swelling. This can happen during a fall or direct impact on the shoulder. It can also occur from chronic wear and tear if the muscle is overworked or not properly conditioned.
3) Age-Related Degeneration
As we age, our muscles and tendons become less flexible and more prone to injury. This may lead to degenerative conditions such as rotator cuff tendinitis or impingement syndrome in the subscapularis muscle, resulting in pain and reduced range of motion.

4) Other Underlying Medical Conditions
Some underlying medical conditions can also lead to subscapularis pain. These may include diabetes, rheumatoid arthritis, thyroid disease, and gout. It’s important to consult with a doctor to rule out any medical causes before beginning treatment.
Signs and Symptoms of Subscapularis Pain
Pain Patterns
The most common symptom of subscapularis pain is a dull ache in the front of the shoulder that can radiate down the arm. It may become worse when reaching overhead or rotating your arm inward, and it may be accompanied by swelling and tenderness in the affected area.
Reduced Range of Motion
Pain can restrict your shoulder’s range of motion, making it difficult to reach overhead or lift your arm away from your body. You may also experience difficulty rotating your arm inward.
Weakness in Affected Arm
The weakened subscapularis muscle can cause your shoulder to become unstable, making it difficult to lift and support the weight of your arm. This may lead to a feeling of weakness and decreased grip strength in the affected arm.

Diagnosing Subscapularis Pain
Physical Examination
Your doctor will begin by performing a physical examination of your shoulder, focusing on range of motion and strength. They may also ask about any activities or injuries that could have contributed to the pain.
Imaging Tests
If further diagnosis is needed, your doctor may order an X-ray or MRI to look for signs of injury or degenerative conditions. These tests can help confirm the diagnosis and determine the severity of your condition.
Differential Diagnosis
Differential diagnosis is a process of ruling out other possible causes for your shoulder pain, such as bursitis or impingement syndrome. Your doctor may ask about any medical history that could be contributing to your symptoms and perform additional tests to confirm or rule out other conditions.

Treatments for Subscapularis Pain
1) Rest and Immobilization
The most important thing you can do for subscapularis pain is to stop any activities that may be causing or aggravating it, and give your shoulder plenty of rest. Your doctor may also recommend using a sling or brace to immobilize your arm and help reduce swelling and pain.
2) Physical Therapy
A physical therapist can help you develop an individualized plan for stretching and strengthening your shoulder muscles. This can help improve flexibility and range of motion, as well as reduce pain and inflammation.
3) Non-Surgical Treatments
Non-surgical treatments are often the first line of defense against subscapularis pain. These may include rest, physical therapy, ice or heat therapy, stretching exercises, and over-the-counter medications such as ibuprofen or acetaminophen.
4) Corticosteroid Injections
Corticosteroid injections can provide relief from the pain and swelling associated with subscapularis injuries. They are most effective when used in combination with physical therapy and rest.
5) Surgery
In some cases, surgery may be recommended to repair any damage to the subscapularis muscle or tendon. This is usually only necessary if all other treatments have failed and the pain persists despite nonsurgical interventions.
