[Purpose] This study compared the differences in electrophysiological characteristics of normal muscles versus muscles with latent or active myofascial trigger points, and identified the neuromuscular physiological characteristics of muscles with active myofascial trigger points, thereby providing a quantitative evaluation of myofascial pain syndrome and clinical foundational data for its diagn...

Readers who are seriously interested in the promising potential of electromyographic detection of endplate noise as a gold standard for identifying TrPs and its likely limitations should be sure to consider the comments on and compare the papers by Couppe et al. and by Kuan et al. that are reviewed in this column. Those interested in writing a first-class paper on clinical research on TrPs shou...

Myofascial pain syndrome (MPS) is described as the sensory, motor, and autonomic symptoms caused by myofascial trigger points (TrPs). Knowing the potential causes of TrPs is important to prevent their development and recurrence, but also to inactivate and eliminate existing TrPs. There is general agreement that muscle overuse or direct trauma to the muscle can lead to the development of TrPs. M...

During the past few months, several new studies, reviews and case studies on myofascial pain syndrome [MPS] and myofascial trigger points [TrPs] have been published. Myofascial pain syndrome and TrPs are increasingly being recognized not only in the United States, but also in Europe. Testa and colleagues [Milan, Italy] published an excellent review article detailing the clinical signs that lead...

Background Myofascial trigger points are commonly described in humans, and many studies have shown abnormal spontaneous electrical activity, spike activity and local twitch responses at these sites. Myofascial trigger points have only rarely been described in horses, and studies of their electrophysiological characteristics have not previously been published. The objective of this study was to ...

Treatment of pain of urogenital origin, chronic pelvic pain syndrome, can be frustrating for patients and physicians. The usual approaches do not always produce the desired results. Visceral pain from pelvic organs and myofascial pain from muscle trigger points share common characteristics. Referred pain from myofascial trigger points can mimic visceral pain syndromes and visceral pain syndrome...
