Objectives
Following this module, participants will be able to:
Explain the basis of increased pain in patients with
fibromyalgia (FM)
Discuss the relationship between pain, fatigue and sleep
disturbance in FM
Suggest non-pharmacologic therapies for pain
Prescribe medications that improve pain in FM

Core Clinical Features of FM
Neurocognitive Impairment
(“Fibro Fog”)
Widespread Pain
• Chronic, widespread pain
is the defining feature
of FM
fibromyalgia
• Patient descriptors of pain
include: aching, exhausting,
nagging, and hurting
• Characterized by confusion, slowed
processing of information and reaction time,
difficulty in word retrieval or speaking,
concentration, attention, short-term memory
consolidation, disorientation
Sleep Disturbance
• Characterized by non-restorative sleep
and increased awakenings
• Abnormalities in the continuity of sleep
and sleep architecture
• Presence of tender points
Fatigue
• Patients describe it as physically or
emotionally draining
Stiffness
• Stiffness in the morning is a common
characteristic of FM

Case Study
Patty is a 32-year-old patient in your
practice who was diagnosed with FM
that appeared to start after she slipped on
some ice.
Patty was advised to attend a local yoga
studio, which has a special FM class.
She was given a morning medication
that targeted mood.
As well, she was referred to a local FM
support group.

in FM is not clearly understood
Peripheral
Peripheral sensitization
Temporal summation (windup) (short-term)
Spine and brain
Central sensitization (long-term)
Change in grey matter volume
Descending inhibition
Other factors

Key Messages for Pain Principles
in FM
There is no “cure” for the pain
Active patient involvement:
activity and non-medication approaches
Important to manage patient’s expectations
Normalize sleep
Normalize mood
Start with medical interventions for pain
that have evidence for efficacy in FM
Start low, go slow!
Target pain control that allows functionality
Non-pharmacologic Treatments
Patient education
Conflicting evidence but some studies have shown
improvements in pain, sleep, fatigue and quality of life
Cognitive-behavioural therapy
Positive effects on coping with and control over pain
• Not proven to improve pain
Proven to improve physical function
Should be done by a trained professional
Aerobic and strengthening exercises
Reduce pain, increase self-efficacy, improve quality of life
and reduce depression
Aerobic exercise should be of low to moderate intensity,
2–5 times/week

* Avoid the trap of re-investigating the patient with firmly diagnosed FM,
but remember: eventually all FM patients will get another disease!
Fatigue in Primary Care –
One-Year Follow-Up
46.9% of those with the initial
presentation of fatigue and with
no diagnosis made at the time of
presentation had, at the end of
one year, one or more of these
diagnoses that could possibly be
the cause of their fatigue.
Note that of musculoskeletal
complaints, most were deemed
non-specific.
Documentation at initiation of
study indicated that 24.1% of
patients had depressive
symptoms. Diagnosis of
depression was made in 4.9%
of subjects at one year.

the fatigue associated with FM
Physical activity is the only
non-pharmacologic strategy proven
to reduce fatigue
What is helpful for complaints of fatigue?
Improvement of sleep hygiene
Moderate physical activity
Pacing
Realistic goal setting
Healthy eating
Cognitive behavioral therapy (CBT)

Pain Leads to Sleep Disruption
Result of noxious pain stimuli = arousal
Decrease in delta waves
Increase in alpha waves
In FM: the structure of the sleep is modified and
there is fragmentation of sleep
Drewes et al. Sleep. 1997;20:632-640.
Non-pharmacologic Interventions
to Improve Sleep
1. Avoid stimulants
2. Regular time to go to bed and to rise
3. Avoid napping through day
4. Regular AM exercise
5. Bed is for sleep and sex

Case Study
Patty is a 32-year-old patient in your practice
who was diagnosed with FM that appeared to
start after she slipped on some ice.
Patty was referred to a “Living with FM”
lifestyle program run by a local
physiotherapist. She was advised to work on
lifestyle and sleep hygiene, and to use a
simple over-the-counter analgesic for
pain control.
She presents for follow-up complaining
that the interventions are “not effective.”

1. Is FM just depression with pain?
2. What treatment modalities may be indicated in
this patient?
3. How would you convince Patty that an
antidepressant medication would be
a good choice?

Maintain a High Index of Suspicion
for the Diagnosis of Major Depressive Disorder
In patients with:
Multiple physical symptoms
Frequent visits and thick charts
Poor sleep, fatigue
Chronic pain (including FM, migraines,
irritable bowel syndrome)
Anxiety disorders
Substance-use disorders
Attention-deficit/hyperactivity disorder
Type II diabetes, ischemic heart disease,
cerebrovascular accidents, cancer, osteoporosis
Mood Disorders in FM
At time of diagnosis, approximately
20%–40% of individuals with FM have an
identifiable current mood disorder
(e.g., depression or anxiety)
Lifetime prevalence of depression: 74%
Lifetime prevalence of anxiety disorder: 60%
In many cases, depression or anxiety may be
the result of chronic pain

Strategy for Explaining Depression
Reinforce neurobiological basis of depression
Acknowledge that chronic pain and depression
frequently co-exist
Use the symptom complex for depression –
SIGECAPS – to help patients understand
symptom grouping
Encourage bibliotherapy to reinforce concepts
Use other members of healthcare team to assist
in psychoeducation
SIGECAPS, mnemonic mnemonic for symptoms of major depression and dysthymia (sleep disorder, interest deficit, guilt, energy deficit,
concentration deficit, appetite disorder, psychomotor retardation or agitation, suicidality)
Non-pharmacologic Treatment

behavioral therapy (CBT) for both
depression and FM

Core Clinical Features of FM
Neurocognitive Impairment
(“Fibro Fog”)
Widespread Pain
• Chronic, widespread pain
is the defining feature
of FM
• Patient descriptors of pain
include: aching, exhausting,
nagging, and hurting
• Characterized by confusion, slowed
processing of information and reaction time,
difficulty in word retrieval or speaking,
concentration, attention, short-term memory
consolidation, disorientation
Sleep Disturbance
• Characterized by non-restorative sleep
and increased awakenings
• Abnormalities in the continuity of sleep
and sleep architecture
• Presence of tender points
Fatigue
• Patients describe it as physically or
emotionally draining
Stiffness
• Stiffness in the morning is a common
characteristic of FM

Mood Disorders in FM
At time of diagnosis, approximately
20%-40% of individuals with FM have an
identifiable current mood disorder
(e.g., depression or anxiety)
Lifetime prevalence of depression: 74%
Lifetime prevalence of anxiety disorder: 60%
In many cases, depression or anxiety
may be the result of chronic pain

Stressors
Some triggering event may trigger FM but is not
a prerequisite
In many cases, onset of FM is gradual, with no
identifiable trigger
Stressors that may trigger FM
Peripheral pain syndromes, physical trauma, infections
(e.g., parvovirus, Epstein-Barr virus, Lyme disease, Q fever),
psychological stress/distress, including sleep disturbances
The development of FM after a precipitating event
may represent the onset of a prolonged and disabling
pain syndrome with considerable social and
economic implications

Diagnosing FM:
Overview
Patient history of FM or related conditions
Personal history
Family history
Physical examination
Most important to rule out other conditions
Differential diagnosis
Clinical/laboratory evaluation to exclude other conditions
such as:
• Osteoarthritis, rheumatoid arthritis, polymyalgia rheumatica
(PMR), hypothyroidism, lupus and Sjögren’s syndrome
Note: Extensive lab evaluation is usually not necessary to rule out FM, In some cases,
a thyroid-stimulating hormone test may be called for. PMR is usually not a problem as it seldom
occurs under the age of 60, whereas the onset of FM after 65 is rare.
Mease. J Rheumatol. 2005;32(suppl 75):6-21; Wolfe et al. Arthritis Rheum. 1990;33:160-172.
Evolution of FM Diagnosis
Evaluation of tender points
Identification of symptoms complex
New Canadian guidelines being developed
Assessment of FM:
American College of Rheumatology (ACR)
Classification Criteria (1990)
History of widespread pain that
has been present for at least
3 months
(ALL of the following should be
present):
Pain on both sides of the body
Pain above and below
the waist
Axial skeletal pain
Pain in at least 11 of 18 tender
point sites on digital palpation
Wolf et al. Arthritis Rheum. 1990;33:160-172.
ACR criteria are both
sensitive (88.4%) and specific (81.1%)
ACR New Proposed Diagnostic Criteria for FM –
2010 (1)
FM can be diagnosed if:
Symptoms for at least 3 months
No other condition to explain pain
Pain + associated symptoms
Wolfe et al. Arthritis Care Res (Hoboken). 2010;62:600-610.
ACR New Proposed Diagnostic Criteria for FM –

Summary
FM is a common disease of middle age
with a female-to-male ratio of 3:1
Simple investigations and history will exclude
other rheumatologic or psychiatric conditions
The 4 cardinal symptoms of FM include
widespread pain, fatigue, sleep disturbance
and cognitive slowing
The current diagnosis of FM is based on
widespread pain plus associated symptom cluster
with a physical exam to exclude other conditions
Menu
Following this module, participants will be able to :
Explain the known pathophysiology of fibromyalgia (FM)
Provide the natural history of FM
Negotiate and explain the diagnosis of FM

Pathogenesis of FM:
Overview
FM is a condition of global dysregulation
of pain processing
Central sensitization is one component
Mechanisms of central sensitization
Excitatory mechanisms
Inhibitory mechanisms
Price DD, Staud R. J Rheumatol. 2005;32 (Suppl 75):22-28.
Pathophysiological Changes
in FM
Increased levels of substance P (>3x)
in patients with FM
Functional magnetic resonance imaging
(fMRI) studies show a marked regional
increase in cerebral blood flow following
a painful stimulus in patients with FM
compared to controls not suffering FM
Deficit in the endogenous pain inhibitory
systems noted in FM patients

Management of FM:
Recommended Treatment Approach
Multidisciplinary therapy individualized to patients’
symptoms and presentation is recommended
A combination of non-pharmacologic and
pharmacologic therapies may benefit most patients
Non-pharmacologic
Aerobic exercise
Cognitive behavioral therapy (CBT)
Patient education
Strength training
Acupuncture*
Biofeedback*
Balneotherapy*
*Limited evidence for efficacy exists
Balneotherapy: treatment of disease or health conditions by bathing
Goldenberg et al. JAMA. 2004;292:2388-2395.
Non-pharmacologic Treatments with
Demonstrated Efficacy Currently in Use
CBT
Positive effects on coping with and control over pain
• Not proven to improve pain
Proven to improve physical function
Should be done by a trained professional
Aerobic and strengthening exercises
Reduce pain, increase self-efficacy, improve quality of life and
reduce depression
Aerobic exercise should be of low-to-moderate intensity,
2–5 times/week
Patient education
Conflicting evidence but some studies have shown improvements
in pain, sleep, fatigue and quality of life

Medical Management of FM:
Considerations
Don’t set unrealistic goals;
target functional improvement
Important to manage patient’s expectations
Keep the patient involved
in treatment decisions
Balance efficacy with side effects
Avoid rapid dose escalation:
start low, go slow!
Medical Management of FM:
Considerations (cont’d)
Use opioids with caution; keep doses low
Refer to the new Canadian practice
guideline on use of chronic opioid therapy
for non-cancer pain
Always augment with non-medical therapy
Polypharmacy may be necessary, but
keep doses low and be mindful of side
effects and function
Polypharmacy
Often necessary for symptom control
May exacerbate or cause some
of the target symptoms of FM (cognitive
impairment, sleep disturbance, fatigue)
Be aware of drug interactions
(e.g., serotonin syndrome)

Start low, go slow – reassure
Use polypharmacy with care
Opioids are controversial

Following this module, participants will be able to:
Differentiate the concepts of functional remission versus
full symptom remission
Establish realistic therapeutic goals with patients
Use interdisciplinary team resources to manage patients
with fibromyalgia (FM)
Objectives
Case Study
Patty is a 32-year-old patient in your practice
who was diagnosed with FM that appeared to
start after she slipped on some ice.
After communicating the diagnosis to her, you
referred her to a local FM lifestyle program.
She was also started on a medication targeting
sleep restoration, her most debilitating
symptom at presentation. She presents for
a follow-up visit.

Questions
1. How do you monitor the effectiveness
of treatments?
2. What is the realistic endpoint of therapy
for FM? Is full remission of symptoms
a reasonable goal?
3. How do you explain or negotiate therapeutic
goals to patients?
4. How could you use an interdisciplinary team
(your own team or resources in your community)
to manage your patients with FM?
Take the time to answer each of the questions
Monitoring Treatment
Currently, there is no currently validated
acceptable tool for assessing response
to treatment
Consider evaluation of patients with FM
in these dimensions:
Pain
Fatigue
Sleep
Functionality (physical and psychological)
Mood
Functional versus Symptom Remission
Symptomatic remission is resolution of all
symptoms associated with the condition
Functional remission is improvement of symptoms
to the point where patients can maximize function
(vocational, interpersonal, social)
Although most patients with FM will not attain full
symptom remission in the short term, the natural
history of FM is more positive
Fate of Patients with FM
Reassure patients that FM is not progressive and
that symptoms remain stable over time1
50% were moderately to greatly improved
(3 year follow-up)2
• The baseline predictors for a favorable outcome:
younger age and less sleep disturbance2
Successful management requires an upbeat,
optimistic approach and EARLY initiation
of effective, individualized therapy

Strategy for Management
Explain the long-term nature of FM
Reassure the patient that it is
not life-threatening
Choose therapies that target the most
disabling symptom(s)
Emphasize functional improvements
Balance medication side effects
with improvement in function

Summary
It is rare that treatment will result
in full symptom remission
Focus for therapy is to increase the level
of function, accepting some degree
of residual symptoms
Educate patients around realistic treatment goals
Where possible, quantify symptoms and level
of function
An interdisciplinary team can assist in education,
establishing and reinforcing treatment goals
For pharmacologic treatment:
start low, go slow!
