Adhesive Capsulitis, or Frozen shoulder is a medical condition that results in severe pain and stiffness in the shoulder. As time progresses, this results in difficulty in movement.

Medically termed “adhesive capsulitis”, frozen shoulder detrimentally impacts the joint within the shoulder. The shoulder pain and stiffness develop into the inability to successfully move the joint.

In most instances, those suffering from this condition will find that they recover anywhere from one year to three years. There are cases when the issue does not resolve itself and intervention, such as physical therapy or surgery, is required for a complete recovery.

Adhesive Capsulitis Causes.

The shoulder joint consists of a collection of bones, tendons, and ligaments. These are closed within an encasement of connective tissue.

When adhesive capsulitis occurs, it indicates that the encasement has started to thicken.

The unnatural thickening makes the encasement tighten up around the shoulder joint. This, in turn, restricts the movement of the joint. In order to truly understand this process, you should have a solid understanding of the basic anatomy of this area of the body:

  • There are three bones that makes up the shoulder. These include the collarbone, the shoulder blade, as well as the humorous – which is the bone of the upper arm of the body.
  • The joint of the shoulder is a ball and socket type. The upper arm bone has a round head and fits within the socket of the shoulder.
  • Synovial fluid surrounds the shoulder joint so that it may move around freely.
  • Connective tissue encases the shoulder joint and all of its components.

When frozen shoulder develops, it indicates the presence or formation of scar tissue around the shoulder joint. The underlying cause has yet to be determined. In most instances, it’s been found that an injury, excessive wear and tear, a fracture, or a disease, such as diabetes, is to blame for the onset of adhesive capsulitis.

Adhesive Capsulitis Stages.

There are three adhesive capsulitis stages and each stage consists of different symptoms.

STAGE 1

Stage 1 is referred to as “Freezing”. This is the onset of the condition. You will slowly start to experience pain. As time progresses, this pain intensifies. It will get to a point where the range of motion of the affected shoulder is limited, then, completely lost. This stage may last as little as 6 weeks or as long as 9 months. The adhesive capsulitis symptoms experienced in this stage include – but, are not at all limited to:

  • Moderate to severe pain when moving the shoulder
  • Increasing pain at night
  • Limitations in movement of the shoulder

STAGE 2

Stage 2 is called the “Frozen” stage. For many, the pain will drop off in this stage and somewhat improve; however, it is common for the stiffness of the condition to remain. In most cases, you will remain in this stage for a period of 3 to 12 months. It is during this time that even the most basic activities that you engage in on a day-to-day basis start to become exceptionally difficult. The following highlights the most common adhesive capsulitis symptoms:

  • Relief may occur, in terms of pain
  • The area becomes stiff and uncomfortable
  • Range of motion and movement are detrimentally impacted

STAGE 3

Stage 3 is called the “Thawing” stage. The motion and ability to move the shoulder start to improve during this stage. This stage may last as little as 6 months or as long as 2 years. You will find that it becomes easier to move. The following covers the adhesive capsulitis symptoms that may be experienced during this stage of the condition:

  • The range of motion of the shoulder joint may start to revert back to normal
  • Many find that the strength of the joint improves during this time
  • Movements start to become easier

 

Adhesive Capsulitis Symptoms.

In addition to the symptoms associated with the adhesive capsulitis stages, there are many general adhesive capsulitis symptoms and situations that may occur. These include those listed below:

  • Adhesive capsulitis only occurs within the shoulder joint and no other location throughout the body.
  • The medical condition is classified as a “self-limited syndrome” that consists of the stages outlined previously in this guide; however, if treated, not all sufferers will go through all of the stages.
  • The range of motion of the shoulder joint is limited, globally. Basically, this means that all of the motion planes of the body are negatively impacted by the general loss of motion that frozen shoulder causes.
  • Generally, all individuals that suffer from frozen shoulder will completely recover; however, most find – without treatment – that there is residual restriction in and around the joint that was impacted by the condition.
  • Once the condition has affected a shoulder, it is rare for it to reoccur in that shoulder; however, it is possible to experience the issue in the opposite shoulder.
  • Should a medical provider order X-ray tests, the images will appear to be normal. There are some cases when the diagnostic tests are able to pick up on the presence of the condition, but this is not common.
  • Many use the terms “frozen shoulder” and “arthritis” interchangeably; however, these are very different issues and are not one in the same.
  • Traditionally speaking, adhesive capsulitis tends to detrimentally impact more women than men; however, both women and men are at equal risk for developing this uncomfortable medical condition.
  • While adhesive capsulitis may develop at any age and to any person, it is more likely to happen at the age of 40 to the age of 65. Medical records have observed those younger that 40 that have the issue. In the same respect, frozen shoulder has been noted in those over the age of 65, too.
  • In excess of 90% of all people have found that they are able to successfully overcome the pain, limited range of motion, and movement issues associated with frozen shoulder given the appropriate treatment for the condition, which is physical therapy.

Adhesive Capsulitis Risk Factors.

While the specific cause of adhesive capsulitis is generally unknown, there are several risk factors identified by medical professionals. These associated factors have made themselves known through the evaluation of the medical histories of those detrimentally affected. The following outlines those factors considered to be the most common:

  • Gender – As mentioned previously, women are generally more likely than men to suffer from frozen shoulder. Medical experts feel that this could directly involve the hormonal changes that women experience in certain periods of their life, such as menopause.
  • Diabetes – Individuals that are diagnosed as having diabetes are more likely to suffer from frozen shoulder. These individuals are up to 20% more likely to experience the condition. It is believed that the glucose molecules within the body of the diabetic are more likely to attach themselves to the collagen-based proteins that are located in the shoulder joint area. In turn, this results in stiffness and discomfort.
  • Medical Conditions and Diseases – Those that have pre-existing medical conditions and/or diseases are more likely to develop adhesive capsulitis. Examples of these issues include complications with the thyroid, cardiovascular problems, lung issues, breast cancer, inflammatory conditions, Parkinson’s disease, and similar issues.
  • Inactivity – Individuals that are inactive – for one reason or another – may develop frozen shoulder. In many cases, this inactivity stems from being sick, injured, or having surgery. Inactivity is known to increase the inflammatory response in the body. When inflammation increase, the encasement of the shoulder joint may become thick and swollen. This, in turn, detrimentally impacts the motion and comfort of the shoulder joint.
  • Shoulder Issues – Those that suffer or have suffered from previous issues of the shoulder may develop adhesive capsulitis. Examples of these issues include the presence of calcium deposits on the rotator cuff of the shoulder, injury to the tendon in the shoulder, and/or any of the muscles present in the area.
  • Previous Shoulder Work – If a person has had shoulder surgery performed or have had fractures or instability treated are more likely to suffer from frozen shoulder.
  • Previous Issue with Frozen Shoulder – While most that have frozen shoulder do not experience the issue again, there are those that stand up to a 17% chance that the issue will develop in the opposite shoulder within a period of 5 years from the initial issue.
  • Age – Those that are over 40 years of age are at a higher risk for developing adhesive capsulitis.

 

Activity Limitations.

Based on evaluations, self-report questionnaires, and what physical therapists have observed in their treatment of frozen shoulder, the activity limitations of this condition include the following:

  • Most patients find that the condition results in pain and varying degrees of difficulty in dressing and grooming.
  • Many state that they suffer from pain while attempting to sleep.
  • Reaching activities result in immense levels of pain. These include reaching activities that result in reaching shoulder level, over the head, and behind the back.

When treating adhesive capsulitis, physical therapists carefully evaluate the activity limitations of the patient. The movement restrictions help practitioners determine the changes of the shoulder joint and the patient’s discomfort level. This, in turn, helps to determine the basic functionality of the shoulder.

Diagnosing Adhesive Capsulitis

When a patient is suspected of having frozen shoulder, they will need to take part in a diagnostic procedure that helps a medical professional confirm the diagnosis. This procedure typically includes a general interview, an examination of the body, as well as medical imaging and lab tests. If you suspect that you have adhesive capsulitis, your doctor will likely ask the following questions:

  • What are your symptoms?
  • How much pain are you experiencing?
  • Does the pain result in sleep problems?
  • Do you have other medical conditions?
  • Have you experienced any injuries to the shoulder or back?
  • Have you ever had any procedures performed on the shoulder?
  • Are there specific movements that seem to increase your pain?
  • Is your movement limited?

The interview will be followed by a physical examination. In this assessment, the medical professional will likely move the affected arm in various directions, apply force, compare one shoulder to another, and evaluate the strength of the shoulder.

Medical imaging and lab tests are typically ordered after the physical examination. These may include – but, are not limited to – X-rays, a MRI, and blood tests that may conclude another medical complication is present.

If you are experiencing pain and stiffness caused by Frozen Shoulder or having any type of shoulder pain, Physical Therapy is a great option to look into.
