II. Definitions
- Myofascial Pain Syndrome (MPS)
- Localized musculoskeletal pain, typically to a few regional Trigger Points
- Contrast with Fibromyalgia which is diagnosed with multiple generalized Tender Points and constitutional symptoms
III. Epidemiology
- Peak onset: ages 30 to 60 years
- Very common cause of Chronic Pain
- Very common syndrome in general population
- In one outpatient studty, Myofascial Pain was responsible for 30% of musculoskeletal pain presentations
- Skootsky (1989) West J Med 151(2): 157-60 [PubMed]
IV. Symptoms
- Localized pain, limited to a few tight regions of spasm and Trigger Points
- Constitutional symptoms (Fatigue, Insomnia, Headache, gastrointestinal upset) are typically absent
V. Signs
- See Chronic Pain Evaluation
-
Trigger Points
- See Trigger Point Location
- Trigger Points are central to Myofascial Pain Syndrome
- Back Muscles are most commonly involved (esp. trapezius Muscle)
VI. Differential Diagnosis
VII. Associated Conditions
VIII. Management (See Chronic Pain)
- Fibromyalgia Non-Pharmacologic Management
- Fibromyalgia Pharmacologic Management
- See Stretch and Spray
- See Trigger Point Injection
- Deep Massage Therapy (20-30 pounds of force)
- Reduces overall Trigger Point related pain, but variable effect on Tension Headache

Osteopathic Manipulative Treatment
- Muscle Energy Technique
- Counter Strain Technique
- Joints and Muscles are manipulated away from a restrictive barrier toward a less restrictive position
- Once Trigger Point pain decreases, position is held for 90 seconds, and then return to a neutral position
- Physical Therapy
- Overall reduction in Trigger Point related pain

- Aerobic Exercise

- Posture enhancing Exercises
- Medications
