What Causes Frozen Shoulder? Prevention Tips

Discover the causes of frozen shoulder and how osteopathy can help prevent it—ideal advice for diabetics, post-surgery patients and those leading inactive lifestyles.

causes of frozen shoulder

Frozen shoulder, or adhesive capsulitis, is a common yet often misunderstood condition characterised by pain and significant restriction of shoulder movement. For many, the prospect of not being able to lift a cup of tea or brush your hair can be alarming. Fortunately, by understanding the causes of frozen shoulder and implementing targeted prevention strategies—including the support of an experienced osteopath—you can significantly reduce your risk and maintain optimal shoulder health.

Understanding Frozen Shoulder

Frozen shoulder affects the shoulder joint capsule, causing it to stiffen and tighten. As a result, the shoulder becomes painful, and its range of motion diminishes considerably. Although the exact pathological processes remain under investigation, adhesive capsulitis generally progresses through three stages:

  1. Freezing (Painful) Stage: Gradual onset of shoulder pain, worsening over 6–9 months and limiting movement.
  2. Frozen (Stiff) Stage: Pain may decrease slightly, but stiffness remains severe, typically lasting 4–6 months.
  3. Thawing Stage: Slow improvement in mobility over 6–12 months, as the capsule gradually loosens.

During each phase, everyday activities—such as dressing, driving or reaching for objects—can become increasingly challenging. As a result, seeking early advice from an osteopath can help manage symptoms and prevent long-term stiffness.

Medical Causes of Frozen Shoulder

Frozen shoulder can arise from various medical and physiological factors. Below are some of the most significant contributors:

1. Diabetes Mellitus

People with diabetes are up to five times more likely to develop frozen shoulder than the general population. High blood sugar levels can lead to changes in connective tissue collagen, causing the joint capsule to thicken and lose elasticity.

2. Post-Surgical Immobilisation

After shoulder or chest surgery—such as rotator cuff repair, mastectomy or cardiac procedures—prolonged immobilisation can precipitate adhesive capsulitis. Without regular gentle movement, the capsule can contract around the joint, leading to pain and stiffness.

3. Trauma and Injury

Significant trauma to the shoulder, including fractures, dislocations or soft-tissue tears, can trigger inflammatory responses. Subsequently, scar tissue formation within the joint capsule may limit movement and contribute to adhesive changes.

4. Thyroid Disorders

Both hyperthyroidism and hypothyroidism have been associated with an increased risk of frozen shoulder. Hormonal imbalances can affect collagen metabolism and joint health, making the shoulder capsule more susceptible to adhesive changes.

5. Cardiovascular Disease

Some studies suggest a link between cardiovascular conditions—such as heart disease or stroke—and frozen shoulder. Although the exact mechanism remains unclear, reduced physical activity and vascular changes may play a role.

Lifestyle-Related Causes and Risk Factors

Beyond strictly medical triggers, certain lifestyle factors can raise your risk of developing frozen shoulder. It is therefore crucial to address these proactively:

  1. Sedentary Behaviour: Prolonged periods at a desk or in front of a screen can limit shoulder mobility.
  2. Poor Posture: Rounded shoulders and forward head carriage place abnormal stress on the shoulder capsule, leading to micro-trauma over time.
  3. Smoking: Nicotine impairs microcirculation and tissue healing, potentially exacerbating capsular fibrosis.
  4. Obesity: Excess body weight is associated with systemic inflammation and may increase the likelihood of musculoskeletal disorders.

By recognising these risk factors early, you can work with an osteopath to design an exercise and lifestyle programme that targets mobility, posture, and overall health.

The Role of Osteopathy in Prevention and Management

Osteopathy takes a holistic approach to musculoskeletal health, focusing on manual therapy, exercise and lifestyle advice. According to the ASA’s guidance on osteopathic marketing, practitioners may legitimately claim to relieve musculoskeletal pain and improve joint mobility, provided evidence supports these claims.

How an Osteopath Can Help

  1. Comprehensive Assessment: Your osteopath will evaluate shoulder mechanics, posture, movement patterns and underlying health conditions.
  2. Manual Therapy: Gentle articulation, mobilisation and myofascial release techniques help restore capsule elasticity and reduce pain.
  3. Exercise Prescription: Targeted stretching and strengthening exercises maintain shoulder mobility and prevent recurrence.
  4. Lifestyle and Ergonomic Advice: Recommendations on workstation setup, posture correction and activity modification reduce undue stress on the shoulder joint.
  5. Holistic Health Management: Guidance on glycaemic control for diabetics, smoking cessation strategies, and weight-management support addresses systemic risk factors.

Furthermore, osteopaths are regulated by the General Osteopathic Council (GOsC) and adhere to strict advertising codes, ensuring any claims are evidence-based and medically responsible, as per the.

Prevention Strategies to Reduce Your Risk

Preventing frozen shoulder often involves a combination of medical vigilance and proactive self-care. Below are practical strategies you can integrate into your daily routine:

1. Maintain Regular Shoulder Movement

Firstly, ensure you perform gentle shoulder circles, pendulum swings, and wall climbs several times a day, especially if you have an existing injury or are diabetic.

2. Incorporate Strength and Flexibility Exercises

Moreover, exercises such as doorway stretches, cross-body adductors and resisted external rotations help preserve capsule viscoelasticity.

3. Optimise Ergonomics and Posture

In addition, adjust your chair, keyboard and monitor height to keep your shoulders relaxed. Use lumbar support and take micro-breaks every 30 minutes to stretch.

4. Manage Underlying Health Conditions

Therefore, if you have diabetes, work with your GP and an osteopath to maintain optimal blood glucose levels. Regular check-ups can mitigate collagen changes that predispose the shoulder capsule to stiffness.

5. Early Post-Operative Mobilisation

After surgery, follow your surgeon’s rehabilitation protocols. However, even modest movement in the pain-free range can prevent capsular adhesion, so discuss gentle mobilisation techniques with your osteopath.

6. Lifestyle Modifications

Furthermore, quitting smoking, achieving a healthy body mass index (BMI) and reducing systemic inflammation through diet—for example, by increasing omega-3 fatty acids—can all contribute to joint health.

By implementing these prevention strategies, you not only reduce your immediate risk of frozen shoulder but also support overall musculoskeletal wellbeing.

When to See an Osteopath

If you experience any of the following, it’s advisable to book a consultation with a qualified osteopath:

  1. Persistent Shoulder Pain: Pain lasting more than 6 weeks, especially if it worsens at night or with rest.
  2. Stiffness and Loss of Movement: Difficulty lifting your arm above shoulder height or behind your back.
  3. Associated Symptoms: Numbness, tingling or weakness in the arm, which may warrant further medical investigation.
  4. Post-Operative Care: After shoulder surgery, to support safe and effective mobilisation.
  5. Chronic Health Conditions: Particularly for diabetics or those with thyroid disorders, to manage systemic contributors to adhesive changes.

At MHV Clinic, our osteopaths are experienced in diagnosing and supporting patients through all stages of frozen shoulder. We work collaboratively with your GP or consultant to ensure comprehensive care that adheres to ASA guidance and GOsC regulations.

Conclusion: Taking Control of Your Shoulder Health

In summary, the causes of frozen shoulder span medical, surgical and lifestyle-related factors. However, by understanding these triggers and engaging in proactive prevention—especially under the guidance of a registered osteopath—you can significantly reduce your risk of adhesive capsulitis. Remember:

  1. Early movement and exercise are essential.
  2. Managing systemic health (e.g. diabetes control) underpins joint wellbeing.
  3. An osteopath can offer tailored manual therapy, exercise programmes and lifestyle advice.

Ultimately, maintaining shoulder mobility wasn’t just about freedom of movement—it’s about preserving quality of life. If you’re concerned about shoulder pain, stiffness or are at high risk, don’t delay: book a consultation with one of our expert osteopaths at MHV Clinic today and take the first step toward a pain-free, active future.
