What You Need to Know About Frozen Shoulder

Shoulder pain can disrupt even the simplest daily tasks, making routine activities feel like a challenge. For many, this discomfort isn’t just temporary—it’s a sign of a more complex condition known as frozen shoulder. Understanding this condition and its implications can empower you to recognize symptoms early, explore treatment options, and regain mobility. Let’s dive into what you need to know about frozen shoulder, from its causes to its impact on daily life.

What is Frozen Shoulder?

A frozen shoulder, also called adhesive capsulitis, occurs when the shoulder becomes increasingly stiff and painful. It develops when the joint capsule surrounding the shoulder becomes thickened and tight. This tightening can reduce the amount of synovial fluid that normally allows the joint to move smoothly. Over time, inflammation and the formation of scar tissue within the shoulder capsule can further limit motion and make it difficult to move the shoulder comfortably.

Frozen shoulder can occur after a minor injury, surgery, or without a known cause. It is also linked to certain conditions, such as diabetes and thyroid disease. People with frozen shoulder may have difficulty with everyday tasks, including dressing, grooming, and reaching.

The condition most commonly affects people between the ages of 40 and 65 and impacts about 2% to 5% of the U.S. population.

Symptoms of Frozen Shoulder

Frozen shoulder typically progresses in three stages. Here’s an overview of the symptoms:

• Freezing stage: The initial phase is marked by increasing shoulder pain, often worse at rest, and significant discomfort with movement. Pain may also disrupt sleep, making rest difficult. Stiffness begins to develop, and daily activities such as brushing hair or reaching overhead can become challenging.
• Frozen stage: As the condition advances, the shoulder becomes increasingly stiff, limiting the range of motion. Pain persists, and movement becomes increasingly restricted, further complicating basic tasks. This stage can also disrupt sleep as pain intensifies.
• Thawing stage: The shoulder begins to recover. Pain typically subsides, and the range of motion gradually improves, although some stiffness may persist for a while. Over time, daily activities become easier, and shoulder function returns.

These stages can vary in length, but understanding them can help set expectations and guide treatment.

How Long Will Symptoms Last?

The stiffness can persist for 1 to 2 years and follows a characteristic course of disease progression.

Typically, the initial period is marked by aching at rest and severe pain with movement. Individuals often have difficulty sleeping due to shoulder pain, along with a progressive loss of motion.

Over the next several months, pain may decrease, but difficulty performing everyday tasks can increase. Eventually, range of motion gradually returns, leading to improved function.

More recently, clinicians have begun to challenge this traditional progression, suggesting it may be altered with effective interventions such as physical therapy.

What to Do and Avoid with Frozen Shoulder

Managing frozen shoulder involves balancing movement with protection.

What to do:

• Perform gentle shoulder exercises to maintain mobility.
• Gradually move the shoulder within a comfortable range.
• Stay consistent with your exercise program.

What to avoid:

• Forcing painful movements that may stretch or tear the joint capsule.
• Prolonged inactivity, which can worsen shoulder stiffness.
• Ignoring symptoms that continue to worsen.

Following these guidelines can help support recovery and prevent further restriction.

How Frozen Shoulder Is Diagnosed

A healthcare provider will typically begin with a physical exam to assess how well you can move the shoulder. They may compare active and passive motion to determine if the joint capsule is restricting movement.

Imaging tests, such as X-rays or MRIs, may be used to rule out other conditions, such as a rotator cuff tear or arthritis. While frozen shoulder may not appear directly on imaging, these tests help confirm the diagnosis by excluding other causes of pain.

Treatment for Frozen Shoulder

A frozen shoulder can be a painful and frustrating experience, but there is treatment available.

Physical Therapy

There is strong evidence supporting the effectiveness of physical therapy in reducing pain and improving range of motion in people with frozen shoulder. Physical therapy interventions may include manual therapy, joint mobilization, therapeutic exercise, stretching, therapeutic ultrasound, laser therapy, and modalities such as electrical stimulation (TENS), heat, or ice.

The approach to treatment often depends on the stage of the condition. In the early phase, therapy focuses on pain relief and gentle mobility. As the shoulder begins to loosen, treatment shifts toward improving range of motion and strength to help the shoulder move more freely.

Steroid Injections

There is evidence that intra-articular steroid injection, combined with physical therapy, can result in significant improvements in shoulder range of motion in the short term (6 weeks). However, the evidence does not show that these improvements are maintained in the long term.

Manipulation

Translational manipulation under anesthesia can be performed for a patient who does not respond to conservative physical therapy treatment.

If you think you may be suffering from a frozen shoulder, make an appointment with your physical therapist or primary care physician to begin your road to recovery.

Risk Factors for Frozen Shoulder

Frozen shoulder doesn’t occur randomly—certain factors can increase your likelihood of developing this painful and restrictive condition. These risk factors include:

• Diabetes: Individuals with diabetes, especially those with poor blood sugar control, are more prone to frozen shoulder.
• Thyroid disease: Hypothyroidism or hyperthyroidism may increase the risk of developing this condition.
• Previous injury or surgery: Shoulder injuries or surgeries, such as rotator cuff repair, can trigger frozen shoulder.
• Other health conditions: Diseases like Parkinson’s disease or cardiovascular conditions can contribute to its onset.
• Age and gender: Frozen shoulder is most common in people ages 40 to 65, with women affected more often than men.

Understanding these risk factors can help with early recognition and timely care.

Complications of Frozen Shoulder

Frozen shoulder doesn’t just affect your immediate ability to move your arm. It can lead to lingering issues that impact your quality of life for months or even years. Frozen shoulder can lead to long-term complications, such as:

• Chronic pain: While pain may decrease over time, some individuals experience persistent discomfort.
• Limited range of motion: Without proper treatment, shoulder mobility may remain limited even after the initial pain subsides.
• Muscle atrophy: Prolonged immobility can lead to muscle weakness and atrophy around the shoulder joint, further complicating recovery.

Understanding these potential complications underscores the importance of timely intervention and rehabilitation to help minimize their effects.

Is Surgery Necessary?

For most individuals with frozen shoulder, nonsurgical treatments like physical therapy and medications are effective in managing symptoms and restoring mobility. However, when these methods fall short, surgery may be the next step. While surgery is not always required, understanding the available options and what they involve can help you make an informed decision if it becomes necessary. Surgical options may include:

• Arthroscopic release: A minimally invasive procedure where the tight capsule around the shoulder is cut to improve range of motion.
• Manipulation under anesthesia: The shoulder is gently moved by a provider while you are under anesthesia to help improve mobility.

These options are typically considered only when conservative treatments have not provided enough relief.

Your Next Steps

Frozen shoulder can be a challenging condition, but with early diagnosis and the right treatment plan, you can regain mobility and reduce pain. Whether it’s physical therapy, steroid injections, or, in rare cases, surgery, there are effective options available to help you manage symptoms and improve your quality of life. If you’re experiencing shoulder pain or stiffness, don’t wait to seek help.
