Definition/Description[edit | edit source]

Fibromyalgia Pain Chart.JPG

Fibromyalgia Syndrome is disease characterized by chronic pain, stiffness, and tenderness of muscles, tendons, and joints, without detectable inflammation. Fibromyalgia does not cause body damage or deformity. Fatigue affects 90 percent of patients and sleep disorders are common. Fibromyalgia can be associated with other rheumatic conditions, and irritable bowel syndrome (IBS). There is no definitive medical test for the diagnosis of fibromyalgia and fibromyalgia symptoms can come and go over time. Diagnosis is made by eliminating other possible causes of the symptoms. It can take time to tease out which symptom is caused by what problem[1]. FMS is NOT just one condition; it's a complex syndrome involving many different factors that can severely impact and disrupt a person’s daily life.

Fibromyalgia Syndrome (FMS) is considered as a systemic problem involving biochemical, neuroendocrine, and physiologic abnormalities, leading to a disorder of pain processing and perception (i.e. allodynia, hyperalgesia). The symptoms associated with FMS may originate from primary or secondary/reactive causes. [2]

The most effective treatment is a combination of education, stress reduction, exercise, and medication.

The below video gives a good summary of FMS

[3]

Prevalence[edit | edit source]

FMS occurs in more than 6 million Americans, or 4% of the population, causing it to be the most common musculoskeletal disorder in the U.S. It affects mainly women (90%) more often than men. Symptoms typically present between the ages of 20-55 years, but individuals have been diagnosed as young as 6 years and as old as 85 years of age.[2]

Pathophysiology[edit | edit source]

The pathogenesis of FMS is theorized to be a malfunctioning of the central nervous system (CNS), characterized by central sensitization, which is a heightened pain perception accompanied by ineffective pain inhibition and/or modulation. This increased response to peripheral stimuli causes hyperalgesia, allodynia, and referred pain across multiple spinal segments, resulting in chronic widespread pain and decreased tolerance to sensory input of the musculoskeletal system.

FMS systemically causes a dysregulation of : neurologic; immunologic; endocrinologic; and enteric organ systems[2].


1. Autonomic Nervous System

The Autonomic Nervous System (ANS) is responsible for regulating the Sympathetic (“fight or flight”) and the Parasympathetic (“rest and digest”) responses. With FMS, patients experience a systemically heightened sympathetic (SNS) response with a diminished parasympathetic (PNS) modulation. Continuous over activation of the SNS results in increased heart rate, excessive gastric secretions and contractions, abnormalities of smooth muscle contraction throughout the digestive tract, rapid and shallow respiration, and vasoconstriction. This can lead to malnutrition due to absorption and digestion disruptions. Prolonged inhibition of PNS alters the neuroimmunoendocrine systems, directly affecting growth hormone secretion by the pituitary gland. This can result in nonrestorative sleep, pain, fatigue, and cognitive/mood symptoms. [2]

2. Immune System

The immune response to infection, inflammation, and/or trauma is a release of cytokines for local healing, which trigger the CNS to release glial cells within the brain and spinal cord for healing support and pain response. With FMS, this auto-immune response is heightened, causing an excess of glia in the body which creates an exaggerated state of pain (chronic).[2]

Causes[edit | edit source]

There are many hypotheses of how multiple factors play a role in the development of FMS. The exact etiology of FMS is still being researched; however, there are several potential causes and risk factors, listed below, that are currently associated with, or increase one’s risk for developing this condition[2].

  • Diet
  • Viral
  • Food pyramid usda.jpg
    Occupation, seasonal, environmental influences
  • Adverse childhood experiences (i.e. PTSD)
  • Psychological and cognitive/behavioral factors
  • Other conditions: RA, systemic lupus erythematosus, or AS

Current research remains inconclusive regarding genetic or hereditary cause of FMS. A family history of FMS is a risk factor.

Characteristics/Clinical Presentation[edit | edit source]

FMSSx.png

Muscle pain is characterized as the major symptom of FMS, often described by patients as “aching or burning” regardless of physical activity. Other symptoms or associated problems occur, with various reports of frequencies, that can also affect function. FMS may cause residual pain sensations at a lower intensity due to repetitive exposure to peripheral stimuli or activity, also known as the “Wind-up Response.”[4][2]


Symptoms are often exacerbated by:

  • Stress
  • Overloading physical activity
  • Overstretching
  • Damp or chilly weather
  • Heat exposure of humidity
  • Sudden change in barometric pressure
  • Trauma
  • Another illness


Associated Co-morbidities[edit | edit source]

Those with FMS are likely to present with several co-morbidities. It is important that a diagnosis of FMS is not overlooked given the presence of additional co-morbidities more commonly diagnosed. Below is a list of common co-morbidities associated with FMS[2]:

Fibromyalgia Diagnostic Criteria (2016)[edit | edit source]

There is no definitive diagnostic test currently available to determine the presence of FMS. A diagnosis of FMS is generally made based upon the results of a physical examination and ruling out other similar conditions. No special laboratory or radiologic testing is necessary for making a diagnosis; however, some recommended lab tests can be performed in order to rule out other conditions. These tests used to rule out include: CBC, ESR, basic chemistry (blood urea nitrogen, creatine, hepatic enzymes, serum calcium), thyroid levels (TSH, T3, and T4), and Rheumatoid factor.

Fibromyalgia may now be diagnosed in adults when all of the following criteria are met[5]:

  • Widespread pain index (WPI) ≥7 and symptom severity scale (SSS) score ≥5 OR WPI 4–6 and SSS score ≥9.
  • Generalized pain, defined as pain in at least 4 of 5 regions, is present.
  • Symptoms have been present at a similar level for at least 3 months.
  • A diagnosis of fibromyalgia is valid irrespective of other diagnoses. A diagnosis of fibromyalgia does not exclude the presence of other clinically important illnesses.

Medication[edit | edit source]

Active rehabilitative approaches have primacy in management, but drugs can help to control symptoms. There is evidence to support the use of amitriptyline, duloxetine, milnacipran or pregabalin, but pure opioids should be avoided[6].

Physical Therapy Management & Exercise[edit | edit source]

Yoga pose.jpg

Education about the pathophysiology and the neuroscience behind the condition is the most effective method in reducing catastrophizing pain symptoms in patients experiencing FMS according to current research. Simple acknowledgement and explanation of symptoms and relaxation strategies can alter a patient’s ability to cope with their condition.

  • Explanation of disorder
  • Reassurance of condition and symptoms
  • Activity management - Pacing, self-monitoring, rest breaks, AVOID exacerbations, set realistic activity goals, etc.
  • Relaxation Techniques - Minimize environmental stress, deep breathing, healthy & active lifestyle habits, adequate sleep, therapeutic massage, etc.

AEROBIC & RESISTANCE EXERCISE[2] [7][edit | edit source]

According to the Ottawa Panel evidence-based clinical practice guidelines (2008), supervised light aerobic exercise and strength/resistance training is highly recommended for the management of patients with chronic pain, like those with FMS. It has been found to increase their capacity for activity while minimizing their symptoms associated with FMS. Specifically, aerobic activity has been shown to improve psychological symptoms associated with depression, cognitive decline, and sleep disturbances. Exercise also improves patient’s cellular metabolism and respiratory capacity, increases lean muscle mass and tone, and increases oxygen uptake within the body’s system(s), which ultimately minimizes their complaints of chronic pain and fatigue.

MANUAL / PASSIVE THERAPY[8][2][4][edit | edit source]

Some studies support that TENS and joint mobilizations foster the reduction of pain as short term relief in patients with FMS. Specifically, patients with chronic back pain due to FMS may benefit from spinal manipulations with limited evidence to support this modality. Moderate evidence shows that the use of passive STM is helpful with pain regulation. In addition, diffuse chronic pain presentations are less likely to be reliable for medical management with TENS compared to localized pain. Passive therapy should not be the foundation of FMS medical management due to the maladaptive illness beliefs and coping strategies for patients’ pain.

Manual lymph drainage therapy and connective tissue massage have also been studied in women with fibromyalgia. Researchers used the Fibromyalgia Impact Questionnaire and the Nottingham Health Profile to measure the impact of the treatment. Their research suggests that both manual lymph drainage therapy and connective tissue massage show improvements in both the FIQ and the Nottingham Health Profile. However, there were significantly greater improvements in the group that received manual lymph drainage therapy, suggesting that manual lymphatic drainage therapy may be preferred over connective tissue massage.

AQUATIC THERAPY & BALNEOTHERAPY [9] [10][edit | edit source]

Recent research has proven that aquatic therapy is a more tolerable workout for people with FMS pain. The water’s buoyancy allows the patient to maintain active movement without exerting excessive energy and/or increasing pressure on their joints. Furthermore, evidence has shown that aquatic therapy and hydrotherapy help in improving the quality of life of those with FMS long term. The underlying symptom(s) of fibromyalgia, central hypersensitivity and pain, may be alleviated by the hydrostatic pressure and the effects of soothing temperature on the nerve endings, along with general muscle relaxation

Ideal pool temperature for aquatic therapy sessions are between 84o F and 90o F

  • 82o F and 84o F for the general population
  • 90o F and 94o F for people with arthritic conditions

An exercise-education program showed a small significant improvement in health status in patients with fibromyalgia and chronic widespread pain, compared with education only. Patients with milder symptoms improved most with this treatment. Moreover, it has been shown that thermal mud baths (and other balneotherapy methods) increase plasma levels of beta-endorphins, thus explaining their analgesic and anti-spastic effects, which is particularly important in patients with FMS.[9][10][4][2][7]

Other Types of Management[edit | edit source]

Occupational Therapy[edit | edit source]

Treatment focuses on activity modification principles, such as working at a moderate pace, frequent positional/postural changes, and resting before fatigue sets in. Patients are encouraged to incorporate regulating principles into all areas of life including self-care, work, and leisure. Proper body mechanics and posture related to home management and work activities are evaluated and adjusted per individual.[11]

Cognitive Behavioral Therapy[edit | edit source]

Research performed by Moseley supports the relationship between pain association and beliefs with physical performance. There is evidence that supports the consideration of cognitive behavioral therapy (CBT) to be implemented in the assessment and plan of care of patients with chronic pain. Growing evidence continues to demonstrate that CBT shows improvement in reports of pain, reduces hyperalgesia, and chronic pain-related brain response in FMS.
One study found that behavioral insomnia therapy for patients with FMS may have a promising impact. The study incorporated patient education on sleeping habits and proper sleeping schedules to reduce the bouts of insomnia experienced by those with fibromyalgia. The researchers concluded that patients who received the behavioral therapy experienced improvement in how long they slept and in their general condition compared to other groups[12].[13][14]

Emotional Awareness and Expression Therapy[edit | edit source]

A group intervention focusing of emotional awareness and expression of emotions was found to be more effective than cognitive behavioral therapy in reducing pain for up to 6 months.[15]

Chiropractic care & Massage [7][edit | edit source]

There is no evidence to support chiropractic care nor therapeutic massage are effective in pain management.

Acupuncture [8][edit | edit source]

While many patients explore this option for relief of pain and fatigue, acupuncture techniques have weak evidence to support their effectiveness in current literature.

Alternative/Holistic Management[edit | edit source]

No evidence to support alternative/holistic management.

Differential Diagnosis [edit | edit source]

The following are all differential diagnoses for FMS. It is possible for several to be present concurrently. Moreover, it is important to determine the presence of all potential facets and diagnoses in order to successfully treat a patient with suspected fibromyalgia.[2]
