The intent of this article is to discuss the evolving role of the myofascial
trigger point (MTrP) in myofascial pain syndrome (MPS) from both a historical and
scientific perspective. MTrPs are hard, discrete, palpable nodules in a taut band
of skeletal muscle that may be spontaneously painful (i.e., active) or painful
only on compression (i.e., latent). MPS is a term used to describe a pain
condition that can be acute or, more commonly, chronic and involves the muscle
and its surrounding connective tissue (e.g. fascia). According to Travell and
Simons, MTrPs are central to the syndrome-but are they necessary? Although the
clinical study of muscle pain and MTrPs has proliferated over the past two
centuries, the scientific literature often seems disjointed and confusing.
Unfortunately, much of the terminology, theories, concepts, and diagnostic
criteria are inconsistent, incomplete, or controversial. To address these
deficiencies, investigators have recently applied clinical, imaging (of skeletal
muscle and brain), and biochemical analyses to systematically and objectively
study the MTrP and its role in MPS. Data suggest that the soft tissue milieu
around the MTrP, neurogenic inflammation, sensitization, and limbic system
dysfunction may all play a role in the initiation, amplification, and
perpetuation of MPS. The authors chronicle the advances that have led to the
current understanding of MTrP pathophysiology and its relationship to MPS, and
review the contributions of clinicians and researchers who have influenced and
expanded our contemporary level of clinical knowledge and practice.
