Understanding Frozen Shoulder: Causes, Symptoms, and Treatment
Frozen shoulder, also known as adhesive capsulitis, is a painful and debilitating condition that affects the shoulder joint. It occurs when the capsule surrounding the joint becomes thickened and inflamed, limiting its range of motion.
Causes and Risk Factors
The exact cause of frozen shoulder remains unclear, but several factors have been identified as increasing the risk:
- Age: People over the age of 40 are more likely to develop frozen shoulder.
- Gender: Women are more prone to the condition than men.
- Diabetes: Individuals with diabetes have a higher incidence of frozen shoulder.
- Immobility: Prolonged periods of shoulder immobility, such as after an injury or surgery, can contribute to the condition.
- Systemic diseases: Certain autoimmune diseases or thyroid disorders may increase the risk.
Symptoms
The primary symptoms of frozen shoulder are pain and stiffness in the shoulder joint. The pain can vary in intensity, from a mild ache to a sharp, throbbing sensation. It may be worse at night or when resting.
As the condition progresses, stiffness becomes more noticeable. It can be difficult to move the shoulder in any direction, making simple tasks like reaching behind your back or dressing challenging.
Other symptoms may include:
- A feeling of "locking" in the shoulder joint
- Weakness in the shoulder
- Limited range of motion
Diagnosis
Diagnosing frozen shoulder typically involves a combination of medical history and physical examination. Your physiotherapist will ask about your symptoms, duration, and any recent injuries or illnesses.
During the physical exam, your physiotherapist will assess your shoulder's range of motion and look for signs of tenderness or inflammation. In some cases, imaging studies like X-rays, MRIs, or ultrasounds may be ordered to rule out other conditions.
It's important to note that there is not one definitive test to help with the diagnosis of frozen shoulder. Diagnosis usually involves excluding other pathology and observing the progression of range of motion reduction across several weeks. Sometimes capsular and or ligament thickening can be seen on medical imaging.
Treatment Options
The goal of treatment for frozen shoulder is to reduce pain, improve range of motion, and restore normal shoulder function. A variety of approaches may be considered, depending on the severity of the condition and individual factors.
Non-surgical treatments often include:
- Physiotherapy: This is typically the first line of treatment and involves exercises, stretching, and mobilization techniques to gradually improve range of motion.
- Medication: Over-the-counter pain relievers and anti-inflammatory drugs can help manage pain and inflammation. In some cases, corticosteroid injections may be used to reduce inflammation within the shoulder joint.
- Heat and cold therapy: Applying heat or cold to the affected area can provide temporary relief from pain and stiffness.
In severe cases of frozen shoulder, surgical intervention may be considered. This typically involves arthroscopic release, a minimally invasive procedure that involves releasing the thickened capsule surrounding the shoulder joint. In recent times, the appropriateness of this procedure has been questioned and as such it is not a commonly used option here in Australia
Timeline for Recovery
The recovery process for frozen shoulder can vary from person to person, but it typically involves three stages:
- Freezing stage: This is the most painful stage, and it can last for several months. During this stage, the shoulder becomes increasingly stiff and painful.
- Frozen stage: The pain may begin to subside, but the shoulder remains very stiff. This stage can also last for several months.
- Thawing stage: As the shoulder capsule begins to loosen, pain and stiffness gradually improve. This stage can take several more months.
It's important to note that the overall recovery time can vary depending on factors such as the severity of the condition, individual health, and adherence to treatment.
Exercise Advice
Physical therapy plays a crucial role in recovering from frozen shoulder. Your physiotherapist will design a personalized exercise program to help improve your range of motion and reduce pain.
Here are some common exercises that may be included in your treatment plan:
- Pendulum exercises: Gently swing your arm back and forth while leaning forward.
- Internal and external rotation: Rotate your shoulder inward and outward while keeping your elbow close to your side.
- Arm circles: Slowly make small circles with your arm.
- Stretching exercises: Gentle stretches can help improve flexibility.
- Active assisted range of motion exercises: Using a stick or pulley can provide support and assistance while gradually increasing your range of motion.
Exercises should be largely pain-free or only done to slight pain. There is no point in pushing too hard, as this can worsen the condition. It's important to perform these exercises under the guidance of a healthcare professional to ensure proper technique and avoid further injury.
Frozen shoulder can be a frustrating and painful condition, but with the right approach, it can be effectively managed. By understanding the causes, symptoms, and treatment options, you can take steps to improve your quality of life.
If you're experiencing shoulder pain or stiffness, don't hesitate to seek help from a physiotherapist. A qualified physiotherapist can accurately diagnose your condition and recommend appropriate treatment.
Remember, you don't have to live with frozen shoulder. With the right care and guidance, you can thaw the ice and regain full range of motion in your shoulder.
