Background: Myofascial trigger points (MTrPs) are hyperirritable spots located in taut bands of muscle fibres. Electrophysiological studies indicate that abnormal electrical activity is detectable ...

Although myofascial trigger points (MTrPs) are rarely mentioned in relation to shoulder pain, they may present an alternative underlying mechanism, which would provide new treatment targets ...

Another theory is that repetitive small trauma to the muscle helps to create a “trigger point" (tight lump or knot in the muscle). Myofascial pain syndrome is characterized by active trigger ...
