Frozen shoulder syndrome (Adhesive capsulitis): Symptoms and treatment
Do you wake up with a sharp pain in your shoulder that won’t go away? Or maybe you find it difficult to reach the top cupboard, as if your arm is locked? If this sounds familiar, you are probably experiencing frozen shoulder syndrome. This condition not only causes discomfort, but can completely change your everyday life. What is frozen shoulder syndrome and how do we help our patients at PhysioArt cope with the pain? Stick around and you will find out.
What is frozen shoulder?
This is a condition characterized by progressive stiffness and loss of movement in the shoulder. The shoulder joint becomes very painful and stiff, progressively losing mobility due to thickening, inflammation, and fibrosis (adhesion) of the joint capsule that surrounds the shoulder joint. The medical term used to describe this condition is adhesive capsulitis.
To understand what is happening to your body, imagine the shoulder joint as a mechanism enclosed in an elastic capsule. Under normal circumstances, this capsule is flexible and allows complete freedom of movement. In adhesive capsulitis of the shoulder, the capsule becomes inflamed, thickens, and shrinks around the joint. Adhesions get formed, which literally ‘stick’ the tissues together.
Who is at risk of developing adhesive capsulitis in the shoulder?
Според данни от National Center for Biotechnology Information (NCBI), adhesive capsulitis mainly affects people between the ages of 40 and 60, with women being more vulnerable than men. The risk of frozen shoulder syndrome increases in people with diabetes, thyroid problems, or after prolonged immobilization of the arm (e.g., after trauma or surgery).
It is advisable to seek professional help if:
- You have shoulder pain that lasts more than 2-3 weeks
- Shoulder mobility gradually starts to suffer
- You have shoulder pain at night that disrupts your sleep
- You cannot perform everyday movements
What are the characteristic frozen shoulder symptoms?
The condition progresses in three distinct stages, each of which can last from months to years. Each of these stages is characterized by different symptoms.
Phase 1: Freezing
It lasts between 2 and 9 months and is characterized by increasing pain and decreasing range of motion. The main symptom is pain that begins gradually and intensifies over time. There is sharp pain in the shoulder when raising the arm or when trying to reach backward (e.g., to take your wallet out of your back pocket). One of the most debilitating symptoms is severe pain in the shoulder at night. Many patients report that they cannot sleep on the affected side, leading to chronic sleep deprivation.
Phase 2: Frozen shoulder
This phase usually lasts from 4 to 12 months, during which time the pain syndrome may subside, but the stiffness intensifies. The acute pain may decrease slightly, but it is replaced by constant dull pain in the shoulder and stiffness, leading to almost complete immobility of the shoulder. Activities such as washing your hair, getting dressed, or driving become extremely difficult.
Phase 3: Thawing
The final phase of frozen shoulder syndrome is the thawing phase, which can take between 5 months and 2 years. During this period, the range of motion gradually improves. The excruciating pain in the shoulder during movement disappears almost completely, and mobility slowly returns. The shoulder begins to ‘loosen up’ and functionality is back to normal.
Difference between frozen shoulder, bursitis, and torn rotator cuff
Before starting treatment, a diagnosis should be made to rule out other causes of shoulder dysfunction. The condition may be misidentified with rotator cuff injury and bursitis, as these also cause shoulder pain and stiffness. Therefore, you may be referred to an MRI scan, X-ray, or ultrasound to confirm the diagnosis.
| Condition | Main complication |
|---|---|
Frozen shoulder |
Thickening, contraction, or inflammation of the joint capsule |
Bursitis |
Inflammation of the fluid-filled sac (bursa) surrounding the joint |
Torn shoulder sleeve |
Injury to the muscles and ligaments of the shoulder |
What do we apply at PhysioArt for frozen shoulder treatment?
At the PhysioArt physiotherapy and rehabilitation center, we do not apply the same template to every patient. Our strength lies in adapting treatment to the specific stage of the disease and the individual needs of each patient. Treatment focuses on pain control and gradual restoration of shoulder mobility. Feedback from satisfied patients is what we pride ourselves in. We are confident that we can help you, too.
The treatment applied at PhysioArt for adhesive capsulitis in the shoulder may include therapies such as:
- Laser therapy - We use a high-intensity laser for the shoulder to penetrate deep into the tissues, relieve pain, and accelerate the recovery process. The laser has a powerful anti-inflammatory effect and stimulates cell regeneration.
- High-frequency magnetic field therapy - This technology helps reduce swelling (if any) and improves microcirculation, which is key to tissue nutrition.
- Shockwave therapy - Shockwave therapy uses strong mechanical pulses that literally ‘break up’ the microscopic adhesions in the capsule and stimulate the body to build new, healthy tissue.
Exercises for frozen shoulder
Exercise is important in treating frozen shoulder (adhesive capsulitis). Although pain and stiffness will often limit activity, carefully selected and regularly performed exercises are the main factor in the gradual restoration of shoulder mobility and function. It is important that the exercises are performed correctly, patiently, and without sudden movements.
In this condition, the joint capsule tightens and loses elasticity. If the shoulder remains immobile, this further exacerbates the problem. Exercises for frozen shoulder can include:
- Improves range of motion
- Reduces stiffness
- Improves blood circulation in the joint
- Supports muscle strength recovery
- Shortens the recovery period
