There are several proposed histopathologic mechanisms to account for the development of trigger points and subsequent pain patterns, but scientific evidence is lacking. However, manual methods are more likely to require several treatments and the benefits may not be as fully apparent for a day or two when compared with injection.10, While relatively few controlled studies on trigger-point injection have been conducted, trigger-point injection and dry needling of trigger points have become widely accepted. The physiology of trigger points themselves is controversial, and therefore the mechanism of action through which injections aimed at trigger points may relieve pain is unknown.39 In 1979, a theory of diffuse noxious inhibitory control was suggested where noxious input from nociceptive afferent fibers inhibited dorsal horn efferents as a counter irritant from a distant location.53 Some support was given to this theory when subcutaneous sterile water improved myofascial pain scores after a brief period of severe burning pain at that site.54 Spontaneous electrical activity was found more frequently in rabbit and human trigger points.9,55 Simons56 theorized that the spontaneous electrical activity found in active trigger point loci was abnormal end-plate potentials from excessive acetylcholine leakage. 2.
