Frozen shoulder, medically known as adhesive capsulitis, is a painful and often debilitating condition that affects the shoulder joint, leading to stiffness, restricted movement, and discomfort. This condition can make everyday activities such as lifting your arm, reaching overhead, or even dressing challenging. Understanding its causes, symptoms, stages, and treatment options is crucial for timely intervention and effective recovery.
What is Frozen Shoulder?
Frozen shoulder is characterized by a gradual loss of shoulder mobility due to inflammation and thickening of the joint capsule. The shoulder becomes “frozen,” making simple tasks like combing your hair or reaching for an object difficult and painful. While it can affect anyone, it most commonly occurs in adults aged 40–60 years and tends to be more prevalent in women than men.
Certain health conditions can increase the risk of developing frozen shoulder. These include:
- Diabetes – People with diabetes are more likely to develop adhesive capsulitis, and recovery may take longer.
- Thyroid disorders – Imbalances in thyroid hormone levels can contribute to joint stiffness.
- Cardiovascular disease – Reduced blood flow may increase joint inflammation.
- Immobilization – Shoulder injuries or surgeries that require the joint to be immobilized can trigger stiffness.
Causes of Frozen Shoulder
Frozen shoulder usually develops when the shoulder joint capsule becomes inflamed, thickened, and tight, limiting movement. The exact cause is often unclear, but several factors are known to contribute:
1. Injury or Trauma
A shoulder injury, fracture, or rotator cuff tear can lead to prolonged immobility, which may trigger frozen shoulder.
2. Medical Conditions
As mentioned, conditions such as diabetes, hypothyroidism, hyperthyroidism, and heart disease increase susceptibility.
3. Post-Surgical Immobilization
After surgery, if the shoulder is kept immobile for too long, scar tissue can form inside the capsule, restricting motion.
4. Inflammatory Conditions
Inflammatory disorders such as bursitis or tendinitis can also contribute to the development of adhesive capsulitis.
Symptoms of Frozen Shoulder
Frozen shoulder typically progresses gradually, and symptoms may worsen over time. Key symptoms include:
- Pain: Dull or aching pain, often worsening at night or with movement.
- Stiffness: Reduced ability to move the shoulder, making routine tasks difficult.
- Limited Range of Motion: Difficulty lifting the arm, rotating the shoulder, or reaching behind the back.
- Gradual Onset: Symptoms often develop slowly and worsen over weeks or months.
Stages of Frozen Shoulder
Frozen shoulder usually progresses through three distinct stages:
1. Freezing Stage (Painful Stage)
During this initial stage, shoulder pain gradually increases, especially at night. Movement becomes limited, but the stiffness is not yet severe. This stage can last from 6 weeks to 9 months.
2. Frozen Stage (Stiffness Stage)
Pain may begin to decrease, but stiffness is at its peak. Daily activities such as dressing, grooming, or lifting objects become extremely difficult. This stage typically lasts 4–6 months.
3. Thawing Stage (Recovery Stage)
Gradually, shoulder movement starts to improve. Complete recovery can take 6 months to 2 years, depending on the severity and timely intervention.
Diagnosis of Frozen Shoulder
A healthcare professional will diagnose frozen shoulder based on:
- Medical History: Reviewing previous injuries, surgeries, or medical conditions.
- Physical Examination: Assessing range of motion and identifying areas of pain or stiffness.
- Imaging Tests: X-rays or MRI may be used to rule out other shoulder problems, such as arthritis or rotator cuff injuries.
Early diagnosis is key to prevent long-term stiffness and restore mobility faster.
Treatment Options for Frozen Shoulder
Treatment focuses on reducing pain, restoring mobility, and improving function. Depending on the severity, options include:
1. Physical Therapy
- Gentle stretching and strengthening exercises help restore movement.
- Techniques like range-of-motion exercises, pendulum swings, and resistance band exercises are commonly recommended.
2. Medications
- Nonsteroidal anti-inflammatory drugs (NSAIDs) can reduce pain and inflammation.
- Pain-relief medications may be prescribed for severe discomfort.
3. Steroid Injections
Corticosteroid injections can reduce inflammation inside the joint capsule, improving mobility and easing pain.
4. Hydro-dilatation
A procedure in which fluid is injected into the joint capsule to expand it, breaking up adhesions and restoring movement.
5. Surgery
Reserved for severe cases that do not respond to conservative treatments. Options include arthroscopic capsular release to remove scar tissue and improve mobility.
Home Care and Lifestyle Modifications
In addition to medical treatment, patients can support recovery at home:
- Regular gentle stretching: Avoid sudden or forceful movements.
- Heat therapy: Warm compresses can reduce stiffness.
- Activity modification: Limit movements that trigger pain but keep the shoulder mobile.
- Healthy lifestyle: Maintaining optimal blood sugar levels (for diabetics) and regular exercise can improve overall joint health.
Prognosis and Recovery
With early intervention and consistent therapy, most patients regain significant shoulder mobility and resume daily activities within 6 months to 2 years. The key factors influencing recovery include:
- Timely diagnosis and treatment
- Adherence to physical therapy
- Management of underlying health conditions
- Avoidance of prolonged shoulder immobility
Frozen shoulder can be challenging, but with proper care, the discomfort can be minimized, and function restored.
When to See a Doctor
Consult a healthcare professional if:
- Shoulder pain persists beyond a few weeks
- You notice progressive stiffness
- Pain interferes with daily activities
- You have a history of diabetes, thyroid issues, or recent shoulder injury
Early intervention can prevent severe stiffness and accelerate recovery.
Conclusion
Frozen shoulder, or adhesive capsulitis, is a common but treatable condition that significantly affects quality of life. Understanding the causes, recognizing the symptoms early, and following a structured treatment plan—including physical therapy, medications, and, if necessary, medical procedures—can help patients regain shoulder mobility, reduce pain, and return to normal daily activities. Patience, consistent therapy, and professional guidance are essential for effective recovery.
