Myofascial pain syndrome is a common musculoskeletal pain disorder characterized
by the presence of myofascial trigger points (MTrPs).
The diagnosis of myofascial
pain syndrome is currently made on clinical grounds.
Numerous diagnostic criteria
are used to identify myofascial pain syndrome, including the localization of
MTrPs. Identifying the presence of MTrPs currently requires the physician to
palpate the symptomatic region. Because the interrater reliability of the
palpation technique has been found to be poor, numerous groups have been
interested in finding objective imaging measures to localize the MTrP. This
comprehensive review focuses on summarizing ultrasound imaging techniques that
have shown promise in visually localizing the trigger point. The authors'
literature search identified three sonographic approaches that have been used in
MTrP localization: conventional gray-scale imaging, Doppler imaging, and
elastographic ultrasound imaging. This review article explains the basic physics
behind the imaging methods and summarizes the characteristics of the MTrP as
identified by the ultrasonic techniques.
