Can Chiropractic Help With Frozen Shoulder (Adhesive Capsulitis)?

Adhesive capsulitis, commonly known as “frozen shoulder syndrome,” is a condition characterized by a progressive and painful limitation of both active and passive movement in the glenohumeral and periscapular joints. It is classified as either primary or secondary.

• Primary adhesive capsulitis occurs when there is no identifiable cause.
• Secondary adhesive capsulitis is more common and develops following a period of restricted shoulder motion, such as after a rotator cuff injury, trauma, or surgery. One study found that patients who had their shoulder immobilized for an unrelated reason were 5-9 times more likely to develop the condition.

Risk Factors for Frozen Shoulder

Adhesive capsulitis is thought to affect 2-5% of the population at some point in their lifetime. Several factors can increase a person’s risk, including:

• Diabetes: The incidence of adhesive capsulitis rises to 10-20% in those with Type 2 diabetes and 36% in those with Type 1 diabetes. Additionally, people with diabetes often experience longer recovery times and poorer outcomes.
• Thyroid disease: Patients with thyroid disease are also at an increased risk.
• Age and Gender: The condition is most common in individuals between the ages of 40 and 65, with a peak incidence between 51 and 55. It affects females more frequently.
• Prior History: The condition does not show a preference for handedness, but those who have had a prior episode in the opposite arm are at greater risk.

Common Symptoms

The primary symptoms of adhesive capsulitis are pain and stiffness.

• Pain: In the early stages, pain is often a dull or aching sensation in the outer shoulder and sometimes the upper arm. It may worsen at night, especially when lying on the affected side. As the condition progresses, pain increases with movement and may even occur at rest.
• Stiffness: Patients experience difficulty moving the shoulder in all directions, particularly with external rotation. Everyday activities like getting dressed, reaching overhead, or reaching behind the back become challenging.
• Reduced Range of Motion: Both active (when you move your arm yourself) and passive (when someone else moves it) range of motion are limited. This reduction often worsens over time if left untreated.

The Stages of Adhesive Capsulitis

Adhesive capsulitis typically progresses through three or four distinct stages.

• Freezing Stage (Painful Stage): This stage lasts from 6 weeks to 9 months and is marked by a gradual onset of pain and increasing shoulder stiffness. Pain limits motion, and it may be worse at night or with movement.
• Frozen Stage (Stiff Stage): Lasting 4 to 12 months, this stage is characterized by a significant loss of motion. Pain may improve slightly, but the marked stiffness remains, and shoulder movement is severely restricted.
• Thawing Stage (Recovery Stage): This final stage can last from 6 months to 2 years, during which there is a gradual return of range of motion and a decrease in both pain and stiffness.

The Connection Between Poor Posture and Adhesive Capsulitis

Poor posture can significantly worsen or contribute to a frozen shoulder, particularly when it leads to shoulder immobility or abnormal movement patterns.

• Reduced Shoulder Mobility: Common poor postures—such as a slouched upper back, a forward head, or rounded shoulders—restrict the natural position and movement of the shoulder blade (scapula). This can limit range of motion and reinforce the stiffness associated with frozen shoulder.
• Muscle Imbalances: Poor postural habits weaken the postural stabilizer muscles (like the lower trapezius and rhomboids) while overworking others (like the upper trapezius). This imbalance can increase strain on the shoulder joint capsule and surrounding tissues, aggravating inflammation.
• Promotes Disuse and Compensatory Movement: Individuals with poor posture often avoid full overhead or rotational arm movements due to discomfort or habit. This lack of regular motion encourages the joint capsule to tighten and form adhesions, which are central to adhesive capsulitis.
• Increases Risk of Impingement: Altered scapular mechanics caused by poor posture can lead to the impingement of soft tissues during arm movement. This creates a cycle of pain, which leads to reduced motion and then to increased stiffness.

How Cervical, Thoracic, or Rib Dysfunction Can Impact Adhesive Capsulitis

Dysfunction in the cervical spine, thoracic spine, or ribs can have a profound impact on a frozen shoulder. These dysfunctions can create a mechanical and neurological cascade that limits shoulder movement, worsens pain, and slows healing.

• Mechanical Interdependence: The shoulder doesn’t work in isolation; it relies on proper mobility and alignment of the cervical and thoracic spines, scapula, and ribs. Dysfunction in these areas alters the way the shoulder moves, which can contribute to or reinforce the restricted range of motion seen in a frozen shoulder.
• Thoracic Spine Dysfunction: A stiff or kyphotic (rounded) thoracic spine reduces the scapula’s ability to rotate upward, a necessary movement for arm elevation. This causes compensatory strain on the glenohumeral (shoulder) joint, increasing capsular stress and contributing to stiffness and pain.
• Cervical Spine Dysfunction: The C5, C6, and C7 nerve roots contribute to shoulder innervation. Dysfunction in these areas (e.g., from joint fixation, a herniated disc, or degeneration) can lead to referred pain in the shoulder, muscle guarding or weakness, and increased sensitivity in the surrounding soft tissues. This neurological component can mimic or intensify frozen shoulder symptoms and lead to diagnostic confusion.
• Rib Dysfunction: Dysfunctional costovertebral joints (where the ribs meet the spine), especially in the upper ribs, can restrict scapular movement and shoulder mechanics. Pain or restriction in the rib cage often leads to postural compensations and decreased shoulder use, reinforcing the adhesive capsulitis cycle.
• Pain-Spasm-Stiffness Cycle: Dysfunction in any of these regions can trigger protective muscle guarding, which further limits motion. This can lead to more adhesions and capsular thickening if the shoulder is not mobilized properly.

Chiropractic Treatment for Frozen Shoulder

Chiropractic care may be a valuable part of a multidisciplinary approach to managing a frozen shoulder, especially when contributing factors like spinal or rib dysfunction, postural issues, or nerve irritation are present.

• Improves Joint Mobility: Chiropractors can perform gentle mobilizations or adjustments to the shoulder joint, the scapulothoracic joint, the cervical and thoracic spines, and the rib joints. This may help reduce stiffness, restore motion to supporting areas, and break the “protective tension” that limits shoulder movement.
• Addresses Spinal and Rib Dysfunction: Chiropractors can identify restricted segments and use spinal manipulation or mobilization that aims to restore motion. This may help to reduce referred pain or nerve tension that mimics or worsens a frozen shoulder.
• Reduces Pain: Manual therapy, adjustments, and soft tissue techniques work to reduce muscle guarding, inflammation, and neural irritation. Some chiropractors also use modalities like ultrasound, electrical stimulation (TENS), or cold laser therapy to support pain relief and improve comfort during rehabilitation.
• Restores Normal Movement Patterns: Chiropractors often include rehabilitative exercises for mobility and strength, along with postural correction strategies and functional movement retraining. This helps improve neuromuscular coordination and prevents compensatory habits that might prolong stiffness.
• Early Detection of Contributing Factors: A chiropractor can assess whether a frozen shoulder is primary or secondary to a condition like cervical radiculopathy, postural dysfunction, or prior trauma. This helps guide more precise treatment and appropriate referrals if needed.
