| '''Frozen shoulder''', medically referred to as '''adhesive capsulitis''', is a disorder in which the [[shoulder]] [[joint capsule|capsule]], the connective tissue surrounding the [[glenohumeral joint]] of the shoulder, becomes inflamed and stiff. Movement of the shoulder is severely restricted. The condition is sometimes caused by injury that leads to lack of use due to [[Pain and nociception|pain]] but also often arises spontaneously with no obvious preceding trigger factor. These seemingly spontaneous cases are usually referred to as [[Idiopathic]] Frozen Shoulder. [[Rheumatism|Rheumatic disease]] progression and recent shoulder [[surgery]] can also cause a pattern of pain and limititation similar to frozen shoulder. Intermittent periods of use may cause [[inflammation]].

| | |
| Abnormal bands of [[tissue (biology)|tissue]] ([[Adhesion (medicine)|adhesions]]) grow between the [[joint]] surfaces, restricting motion. There is also a lack of [[synovial fluid]], which normally helps the shoulder joint move by [[lubrication|lubricating]] the gap between the [[humerus]] (upper arm [[bone]]) and the socket in the [[scapula]] (shoulder blade). It is this restricted space between the capsule and ball of the humerus that distinguishes adhesive capsulitis from a less complicated, painful, stiff shoulder. People with [[diabetes]], [[stroke]], [[lung disease]], [[rheumatoid arthritis]], and [[heart disease]], or who have been in an accident, are at a higher risk for frozen shoulder. Adhesive capsulitis has been indicated as a possible adverse effect of some forms of highly active antiretroviral therapy ([[HAART]]). The condition rarely appears in people under 40 years old and (at least in its idiopathic form) is much more common in women than in men. Frozen shoulder in diabetic patients is generally thought to be a more troublesome condition than in the non-diabetic population. <ref>1</ref> <!-- Need to convert this into a proper reference (i.e. author name etc.) then use {{reflist}} in References. -->

| ==Prevention==
| |
| To prevent the problem, a common recommendation is to keep the [[shoulder]] [[joint]] fully moving to prevent a frozen shoulder. Often a shoulder will hurt when it begins to freeze. Because pain discourages movement, further development of [[Adhesion (medicine)|adhesions]] that restrict movement will occur unless the joint continues to move full range in all [[Anatomical position|directions (adduction, abduction, flexion, rotation, and extension)]]. Therapy will help one continue movement to discourage freezing and warm it. A [[medical doctor]] referral is needed before [[occupational therapy|occupational]] or [[physical therapy]] can begin under law in most US states. Medical referral is not required for physical or occupational therapy in most Canadian provinces.

| ==Signs and diagnosis==
| |
| With a frozen shoulder, one [[sign (medicine)|sign]] is that the joint becomes so tight and stiff that it is nearly impossible to carry out simple movements, such as raising the arm.
| |
| People complain that the stiffness and pain worsen at night. Pain due to frozen shoulder is usually dull or aching. It can be worsened with attempted motion. A doctor, or therapist ([[occupational therapy|occupational]], massage or [[physical therapy|physical]]), may suspect the patient has a frozen shoulder if a [[physical examination]] reveals limited shoulder movement. Frozen shoulder can also be diagnosed if limits to the active range of motion (range of motion from active use of muscles) are the same or almost the same as the limits to the passive range of motion (range of motion from a person manipulating the arm and shoulder). An [[arthrogram]] or an [[MRI]] scan may confirm the diagnosis - although in practice this is rarely required. Most orthopaedic specialists make the diagnosis of frozen shoulder by recognising the typical pattern of signs and symptoms.
| |
| | |
| Physicians have described the normal course of a frozen shoulder as having three stages:
| |
| | |
| Stage one: In the "freezing" or painful stage, which may last from six weeks to nine months, the patient has a slow onset of pain. As the pain worsens, the shoulder loses motion.
| |
| | |
| Stage two: The "frozen" or adhesive stage is marked by a slow improvement in pain, but the stiffness remains. This stage generally lasts four months to nine months.
| |
| | |
| Stage three: The "thawing" or recovery, during which shoulder motion slowly returns toward normal. This generally lasts five months to 26 months.
| |
| | |
| ==Management==
| |
| Management of this disorder focuses on restoring joint movement and reducing shoulder pain. Usually, it begins with [[nonsteroidal anti-inflammatory drug]]s (NSAIDs) and the application of heat, followed by gentle stretching exercises. These stretching exercises, which may be performed in the home with the help of a [[physical therapist|physical]], massage or [[occupational therapist]], are the treatment of choice. In some cases, [[transcutaneous electrical nerve stimulation]] (TENS) with a small battery-operated unit may be used to reduce pain by blocking [[nerve impulse]]s.
| |
| | |
| One of the most successful treatments for frozen shoulder has been shown to be The [[Bowen Technique]] with average range of motion improvement of 23° during controlled trials.
| |
| | |
| If these measures are unsuccessful, the doctor may recommend [[Joint manipulation|manipulation]] of the shoulder under [[general anesthesia]] to break up the adhesions. [[Surgery]] to cut the adhesions is only necessary in some cases.
