MPS, FM

Introduction to Fibromyalgia and Myofascial Pain Syndrome

  • Fibromyalgia (FM) and Myofascial Pain Syndrome (MPS) are chronic pain syndromes that are often confused due to their overlapping symptoms.

  • Each condition has its own distinct etiology, leading to different treatment approaches.

  • Key Differences:

    • Individuals with FM process nociceptive signals differently compared to those without FM.

    • Individuals with MPS experience localized changes in the muscle.

Fibromyalgia (FM)

Definition

  • Defined by the American College of Rheumatology as a chronic condition characterized by widespread pain:

    • Pain covers half the body (either the right or left side, upper or lower half) and includes axial skeleton.

    • Symptoms persist for more than 3 months.

    • Tender Points: 11 out of 18 specified tender points throughout the body.

    • Other symptoms include nonrestorative sleep, morning stiffness, and fatigue leading to diminished exercise tolerance.

Prevalence

  • An estimated 2% of the population (nearly 5 million adults aged 18 and older) suffer from FM.

  • Women are disproportionately affected (3.4% women vs. 0.5% men).

  • Prevalence increases with age, affecting 7.4% of women aged 70 to 79.

Clinical Characteristics

  • Symptoms typically arise in early to middle adulthood.

  • Symptoms can often initiate after physical trauma, such as motor vehicle accidents or viral infections.

  • Common complaints:

    • Muscular pain predominantly in areas such as the scapula, head, neck, chest, and low back.

    • Fluctuating symptoms; individuals may experience days of relief followed by increased pain.

  • Associated with a higher incidence of conditions like:

    • Tendonitis, headaches, irritable bowel syndrome, temporomandibular joint dysfunction, restless leg syndrome, mitral valve prolapse, anxiety, depression, and memory issues.

Factors Contributing to Flares

  • While FM is noninflammatory, several factors can aggravate symptoms:

    • Environmental Stresses: Changes in weather, significant changes in barometric pressure, cold weather, dampness, fog, rain, and fluorescent lights.

    • Physical Stresses: Repetitive activities, prolonged sitting or standing, and working rotating shifts.

    • Emotional Stresses: Normal life stresses can impact symptom severity.

Management of Fibromyalgia

  • Incorporates a multifaceted approach:

    • Exercises: Aerobic and strengthening exercises.

    • Medications: Both prescription and over-the-counter options.

    • Pacing Activities: Instructions aimed at managing daily activities to avoid symptom fluctuations.

    • Cognitive Behavioral Therapy: Addressing emotional and psychological factors.

    • Stress Management: Avoidance of known stressors.

    • Lifestyle Modifications: Reducing alcohol and caffeine intake, and dietary changes.

    • Physical Therapy Techniques: Stretching techniques, trigger point therapy, massage.

Myofascial Pain Syndrome (MPS)

Definition

  • Myofascial Pain Syndrome (MPS) is defined as a chronic, regional pain syndrome characterized by:

    • Myofascial trigger points (MTrPs) that create specific patterns of referred pain along with sensory, motor, and autonomic symptoms.

    • Trigger Points: Hyperirritable areas in a tight band of muscle with dull, aching, and deep pain.

    • Associated impairments include:

      • Decreased range of motion (ROM) and strength with increased pain during muscle stretching.

Prevalence

  • MPS can affect 85% of the general population at some point in their lives.

  • Trigger points can be categorized as:

    • Active: Spontaneous pain or pain upon movement, potentially causing local or referred pain.

    • Latent: Pain only felt when the area is palpated.

Possible Causes of Trigger Points

  • The exact etiology is not fully understood, but potential causes include:

    • Chronic Overload: Repetitive activities maintaining muscles in a shortened position.

    • Acute Overload: Sudden injuries or trauma.

    • Poor Conditioning: Weak muscles compared to regularly exercised ones.

    • Postural Stress: Prolonged poor posture or workstation ergonomics.

    • Poor Mechanics: Improper lifting techniques, and direct trauma.

Pathophysiology of MPS

  • Initial changes in muscle leading to myofascial pain involve the development of a taut band, indicating a motor abnormality.

Clinical Presentation of Myofascial Pain Syndrome

  • Pain on Compression: Local pain and/or referred pain elicited through pressure.

  • Local Twitch Response: A quick contraction of muscle fibers in the taut band.

  • Muscle Tightness: Restricted range and increased sensitivity during stretches.

  • Local Myasthenia: Muscle may feel weak with no observable atrophy.

  • Autonomic Phenomena: Symptoms may include vasoconstriction and hypersecretion.

Diagnosis of MPS

Essential Criteria

  • Palpable taut band in accessible muscles.

  • Tender spot within the taut band.

  • Patient recognizes current pain complaint upon pressure by examiner.

Confirmatory Observations

  • Local twitch response with compression.

  • Referred pain sensation noted during palpation.

  • Confirmed via electromyography (EMG).

Treatment and Management of Myofascial Pain Syndrome

Three Main Components

  • Correcting Contributing Factors: Addressing chronic overload issues.

  • Trigger Point Elimination Techniques:

    • Contract-relax methods, spray and stretch, dry needling/injections.

  • Muscle Strengthening: Incorporating a variety of therapeutic techniques like active release, trigger point pressure release, and massage.

Q/A Format on Fibromyalgia and Myofascial Pain Syndrome

Q1: What are Fibromyalgia (FM) and Myofascial Pain Syndrome (MPS)?

A1: FM and MPS are chronic pain syndromes characterized by overlapping symptoms but distinct etiologies, leading to different approaches for treatment.

Q2: How does nociceptive signal processing differ between individuals with FM and those without?

A2: Individuals with FM process nociceptive signals differently, indicating a central sensitivity, while those with MPS do not exhibit this unique signal processing.

Q3: What are the defining characteristics of Fibromyalgia according to the American College of Rheumatology?
