Frozen Shoulder: Symptoms, Causes, and Physiotherapy Management

If your shoulder feels increasingly painful and difficult to move without any clear injury, you may be experiencing frozen shoulder. This condition, known in medical terms as adhesive capsulitis, makes shoulder movement limited and painful in a gradual way. This article discusses what frozen shoulder is, its stages, its symptoms and risk factors, and how physiotherapy can support the recovery process. This information is general in nature and is not a substitute for a direct examination by a healthcare professional.

What is frozen shoulder?

The shoulder joint is wrapped in a capsule of connective tissue that is normally loose enough to allow the arm to move in various directions. In frozen shoulder, this capsule thickens, tightens, and loses its flexibility. As a result, the range of movement within the joint narrows, giving rise to pain together with a limitation of movement that develops slowly over several months.

A hallmark of this condition is that the limitation of movement occurs both when you try to move the arm yourself and when someone else moves it for you. This is what distinguishes it from ordinary muscle pain.

The three stages that commonly occur

Frozen shoulder generally develops through three stages. It is important to understand that each stage can last for several months and its duration varies greatly from person to person.

• Painful stage (freezing) — pain gradually increases, especially when moving the shoulder, and the range of movement begins to decrease.
• Stiff stage (frozen) — the pain sometimes eases slightly, but stiffness becomes the most prominent feature, making daily activities feel difficult.
• Recovery stage (thawing) — shoulder movement gradually returns over time, although the process can take quite a while.

Because its course is gradual and differs from one person to another, there is no recovery timeline that can be guaranteed for everyone. Patience becomes an important part of this process.

Symptoms to recognize

The symptoms of frozen shoulder tend to develop slowly rather than appear suddenly. Some of the commonly experienced complaints include:

• Pain at night — many people find the shoulder more painful when lying down, so sleep becomes disturbed.
• Difficulty raising the arm — lifting the hand upward or out to the side feels limited.
• Difficulty with daily activities — such as combing the hair, getting dressed, or reaching the back of the body.
• Persistent stiffness — the shoulder feels as if it is "locked" even after resting.

Risk factors

Frozen shoulder can happen to anyone, but several factors are known to be able to increase the likelihood of it. Recognizing these factors can help you be more alert to changes in your shoulder.

• Age — it most often appears in the age range of about 40 to 60 years.
• Diabetes — people with diabetes have a higher risk of experiencing this condition.
• Immobilization — a shoulder that has not been moved for a long time after an injury, surgery, or the use of an arm sling is more prone to becoming stiff.
• Sex — it is generally found more often in women.

How physiotherapy can help

Management of frozen shoulder is generally conservative and gradual. The aim is to manage pain while slowly restoring the shoulder's range of movement without forcing it. Physiotherapy plays an important role in this process through an approach tailored to each patient's stage and condition.

• Gradual range-of-motion exercises — gentle movements increased slowly to help maintain and restore mobility.
• Stretching — directed stretching to help loosen the tightened joint capsule.
• Manual therapy — techniques performed by the physiotherapist to help improve joint movement.
• Pain and activity management — strategies for organizing daily activities so that the shoulder is not overburdened.
• Education — an understanding of the condition and self-directed exercises at home so that recovery is more consistent.

At Care Physio, treatment is carried out by STR-certified physiotherapists within an integrated clinic environment (Pediatrics, Psychology, and Orthopedics). An approach such as Dynamic Neuromuscular Stabilization (DNS) may be considered as part of an exercise program to help restore movement patterns and shoulder stability, always tailored to the needs of each patient.

When to consult

Because recovery from frozen shoulder proceeds gradually and is highly individual, it is important to go through this process with patience and appropriate guidance. However, see a doctor promptly if shoulder pain appears suddenly after trauma or a fall, or if it is accompanied by swelling, redness, or fever, as this may indicate another condition that requires different treatment. A direct examination by a healthcare professional will help confirm the cause of the complaint and determine the most appropriate treatment for you.
