The myofascial pain syndrome (MPS)
Features of MTrPs
Motor: disturbed motor function muscle weakness as a result of
motor inhibition muscle stiffness restricted range of motion
Autonomic: vasoconstriction vasodilatation
Features of MTrPs
Features of MTrPs
Sensory: local tenderness referral of pain to a distant site peripheral sensitization central sensitization
Definition and type of Terms
Check handout please
Examples of the two directions in which trigger point may referred
A). Peripheral projection of pain from suboccipital and infraspinatus trigger points. (
B). Mostly central projection of pain from biceps brachii trigger points with some pain in the region of the distal tendinous attachment of the muscle.

Prevalence
Research has shown that MTrPs are commonly associated with facet joint dysfunctions, disc herniation, osteoarthritis, migraine, tension type headache, (Fybromyalgia), visceral disorders etc.Dommerholt, J. and T. Issa, Differential diagnosis: myofascial pain, in Fibromyalgia syndrome; a practitioner's guide to treatment, L. Chaitow, Editor. 2003, Churchill Livingstone: Edinburgh. p. 149-177.
A survey of APS (American Pain Society)-members shows that 88.5% consider MPS as a legitimate diagnosisHarden, R.N., et al., Signs and symptoms of the myofascial pain syndrome: a national survey of pain management providers. Clin J Pain, 2000. 16(1): p. 64-72.
80% of 1096 subjects involved in low-velocity activity developed active trigger points (MTrP)Schuller, E., W. Eisenmenger, and G. Beier, Whiplash injury in low speed car accidents. J Musculoskeletal Pain, 2000. 8(1/2): p. 55-67.
MTrPs have been identified with:
Radiculopathies joint dysfunction disk pathology tendonitis Craniomandibular
dysfunction migraines tension-type headaches carpal tunnel syndrome computer-related disorders whiplash associated
disorders spinal dysfunction
pelvic pain and other urologic syndromes
most pain syndromes nocturnal cramps phantom pain etc.
Etiology of MTrPs
Acute Overuse Direct Trauma Persistent Muscular Contraction
(emotional or physical cause), i.e,: poor posture, repetitive motions, stress response
Prolonged Immobility Systemic Biochemical Imbalance
Diagnostic Criteria taut band: the group of
tense muscle fibers extending from a trigger point to the muscle attachments, the tension being caused by contraction knots that are located in the trigger point region
Diagnostic Criteria
spot tenderness within the taut band (nociceptive input into the dorsal horn contributing to wind-up and central sensitization)
local twitch response.
referred pain.

Identification
Myofascial Trigger Points are identified by physical examination, specifically by palpation
There are two palpation techniques:
Flat palpation Pincer palpationdependent upon the muscle
Manual Trigger Point Therapy
Trigger Point Techniques Trigger Point Compression (Technique I) Manual stretching of the taut band in muscle fibre direction (Technique II)
Release Techniques: Myofascial Release (Technique III) Intermuscular mobilisation (Technique IV)
Stretching Techniques: Therapeutic stretching (Technique V) Self stretching (Technique VI)
