Adhesive capsulitis – frozen shoulder

ADHESIVE CAPSULITIS - FROZEN SHOULDER

Adhesive capsulitis is a shoulder condition characterized by gradually increasing pain and stiffness that lead to a marked reduction in shoulder movement, as if the joint has become “frozen”. Over time the shoulder capsule becomes inflamed, thickened and tight and fibrotic adhesions form, which restrict space and motion within the joint. Symptoms usually develop slowly, worsen over several months and then, in many cases, gradually improve, but the whole process can last many months to years and some patients are left with persistent limitations. Adhesive capsulitis most commonly affects people between 40 and 65 years of age and is associated with conditions such as diabetes and thyroid disorders, as well as with periods of shoulder immobilization after injury or surgery. Early recognition, accurate diagnosis and a structured physiotherapy programme can help reduce pain and restore as much movement and function as possible.

From pain to stiffness

In adhesive capsulitis the normally flexible shoulder capsule becomes thick, contracted and adherent, leading to global loss of both active and passive range of motion and significant pain. Patients often describe an insidious onset with gradually worsening shoulder pain, especially at night, and increasing stiffness that makes tasks such as dressing, reaching overhead or fastening a bra or seatbelt difficult. Loss of external rotation and abduction is typically most noticeable and is present both when they move on their own and when someone else tries to move the arm.

Diagnosis is mainly clinical, based on this characteristic pattern of pain and reduced motion, along with ruling out other causes of shoulder symptoms. Treatment is primarily non-operative and often prolonged, combining pain-relieving strategies, possible intra-articular injections and a stage-appropriate physiotherapy programme. In the early “freezing” phase, management focuses on pain control and gentle movement within tolerance, while in the “frozen” and “thawing” phases therapy gradually shifts towards more intensive stretching, mobilization and strengthening to regain movement and shoulder function.

Setting realistic rehabilitation goals in adhesive capsulitis

Adhesive capsulitis is a condition that requires patience, realistic expectations and a carefully planned physiotherapy strategy. In the early, more painful stages the goal is not to immediately “force” the shoulder to move with aggressive stretching, but to control pain, maintain comfortable range of motion and avoid complete immobilization, which can actually worsen stiffness. As pain gradually settles and the shoulder becomes more stiff than acutely irritable, the programme shifts towards regular, gentle stretching, joint mobilization within safe limits and exercises designed to restore functional overhead and behind-the-back movements.

Physiotherapists also focus on how you use your shoulder throughout the day. Education about more efficient movement patterns, adapting your environment so that frequent tasks occur at more comfortable heights, building a simple but consistent home exercise routine and adjusting load according to the current stage are key components of care. Close collaboration with your doctor regarding possible injections or medication and ongoing re-evaluation of shoulder motion help shape a realistic plan with the aim not necessarily of a “perfect” joint, but of a shoulder that is as painless and functional as possible for your individual needs.

Frequently Asked Questions

What is adhesive capsulitis?
It is a condition in which the shoulder capsule becomes thick, tight and adherent, leading to pain and marked loss of shoulder motion.
What are the most common symptoms?
Gradually increasing shoulder pain (often worse at night), difficulty with dressing or reaching and progressive stiffness in all directions of movement.
In which age group is it most common?
It most often affects people between 40 and 65 years of age and is more common in women and in those with a previous episode in the opposite shoulder.
Are there risk factors for adhesive capsulitis?
Yes, it is more common in people with diabetes, thyroid disease or after prolonged shoulder immobilization following injury or surgery.
Is adhesive capsulitis a permanent condition?
It has long been considered self-limiting, but newer evidence suggests many patients experience prolonged symptoms and some residual stiffness.
Is it normal for the pain to be worse at night?
Night pain is very common in adhesive capsulitis and usually improves gradually with proper positioning during sleep and ongoing rehabilitation.
Should I immobilize my shoulder to avoid pain?
No, prolonged immobilization can worsen stiffness; gentle, controlled movement within pain-free limits is generally preferred.
Will my shoulder go back to completely normal?
Many patients regain very good function, but some may have mild residual stiffness; early and consistent rehabilitation improves the likelihood of a good outcome.
