FROZEN SHOULDER (ADHESIVE CAPSULITIS): SYMPTOMS, CAUSES, AND TREATMENT
Frozen shoulder, known medically as adhesive capsulitis, is a common condition characterized by shoulder pain and significant stiffness. It results from inflammation and the formation of scar tissue (adhesions) around the shoulder joint, which restricts movement.
This is one of the most frequent causes of shoulder pain. The good news is that with an early and accurate diagnosis, frozen shoulder treatment can be highly effective, leading to a faster recovery.
WHAT ARE THE SYMPTOMS OF FROZEN SHOULDER?
The primary symptoms are a dull, aching pain, usually felt deep in the shoulder area. This pain often worsens with movement or at night.
Patients typically notice these limitations in daily activities:
Inability to lift the arm fully overhead.
Difficulty throwing a ball.
Trouble reaching forward.
Inability to reach behind the back (e.g., fastening a bra, scratching the back).
Difficulty reaching to the side, requiring twisting the torso (e.g., pulling a car seatbelt).
Pain when sleeping on the affected side.
Sometimes, these symptoms can mimic other conditions like subscapularis tendonitis. Therefore, a prompt and accurate diagnosis is crucial for effective treatment. Other potential causes of shoulder pain include shoulder osteoarthritis or a rotator cuff tear.
COMMON CAUSES AND RISK FACTORS FOR FROZEN SHOULDER
While the exact trigger for frozen shoulder isn’t always clear, it’s most commonly seen in adults aged 40-60. The condition is often linked to two main factors: underlying health issues and a history of shoulder immobility.
Systemic Diseases: Patients with certain chronic conditions have a higher risk of developing frozen shoulder. These include:
Diabetes
Heart disease
Hyperthyroidism (overactive thyroid)
Hypothyroidism (underactive thyroid)
Immobility or Surgery: Patients who have had shoulder surgery are at higher risk, especially if they do not perform regular rehabilitation exercises. Prolonged immobility from an injury (like a broken arm), infection, or other causes can also lead to a frozen shoulder.
UNDERSTANDING THE ANATOMY OF FROZEN SHOULDER
Frozen shoulder occurs when the shoulder capsule—the strong connective tissue surrounding the shoulder joint—becomes inflamed, thickened, and tight. This process, as seen in the image below, causes pain and severely limits the shoulder’s range of motion. The capsule’s job is to hold the joint in its socket; when it thickens and shortens (right image), movement becomes painful and restricted.
THE THREE STAGES OF FROZEN SHOULDER
The condition typically progresses through three distinct phases:
Stage 1: Freezing Phase This stage is marked by significant inflammation and increasing pain, especially at night. The shoulder’s range of motion begins to decrease.
Stage 2: Frozen Phase In this stage, the pain may lessen slightly, but the stiffness becomes much worse. Daily activities become extremely difficult as the shoulder “freezes.”
Stage 3: Thawing Phase (Recovery) The shoulder’s range of motion gradually begins to improve. Pain continues to decrease. This phase can be long, lasting anywhere from 1 to 2 years (Kelley et al 2009, Walmsley et al 2009, Hannafin et al 2000).
Research indicates that treatment should initially focus on pain relief, followed by physical therapy to restore the joint’s range of motion (Hanchard et al., 2011).
WHEN IS SURGERY OR MANIPULATION CONSIDERED?
Surgery is typically reserved for severe cases where the joint is completely stuck and does not respond to conservative physical therapy.
A doctor might recommend manipulation under anesthesia (MUA) (where the doctor moves the shoulder to break up adhesions) or arthroscopic surgery to release the tight joint capsule. However, studies show that 60-80% of patients respond well to non-surgical treatment, though full recovery can take 18-24 months (Grant et al., 2013, Castellarin et al., 2004).
PHYSICAL THERAPY: THE CORE OF FROZEN SHOULDER TREATMENT
Physical therapy for frozen shoulder is tailored to the patient’s specific stage and goals. The primary focus is on reducing pain and increasing the range of motion (ROM) to restore function.
This can involve several techniques, including joint mobilization, kinesiology taping, stretching, and exercises (Page & Labbe 2010). The most effective methods are often Mobilization with Movement (MWM)and a prescribed therapeutic exercise program (Doner et al., 2013, Yang et al., 2007).
Here are some common exercises:
1. PENDULUM STRETCH
Lean over, supporting your good arm on a table. Let the affected arm hang straight down. Gently swing the arm in small circles (10 clockwise, 10 counter-clockwise). Do this once daily. As you improve, you can widen the circles or hold a light dumbbell. Do not force the movement.
2. TOWEL STRETCH (INTERNAL ROTATION)
Hold a small towel behind your back horizontally. Grasp one end with your good hand and the other with your affected hand. Use your good arm to gently pull the towel upwards, stretching the affected shoulder. Do not force it. Repeat 10-20 times daily.
3. FINGER WALK
Stand facing a wall, about three-quarters of an arm’s length away. With your elbow slightly bent, touch the wall with your index and middle fingertips. Slowly ‘walk’ your fingers up the wall as high as you comfortably can. Lower the arm and repeat 10-20 times daily.
4. ISOMETRIC INTERNAL ROTATION
Place a folded towel under the elbow of your affected arm. Bend your elbow to 90 degrees. Use your other hand to press against the palm of your affected hand. Gently try to rotate your affected arm inward while your good hand provides resistance.
5. ISOMETRIC EXTERNAL ROTATION
This is the opposite of the previous exercise. In the same position, place your good hand on the back of your affected hand. Gently try to rotate your affected arm outward while your good hand provides resistance.
