Technique used to deal myofascial pain syndrome. These are motor, sensory and autonomous symptoms and signs caused by trigger points.
But, what is a trigger point? It is an hyperirritable point within a tense muscle band. The muscle is shortened so can not reach nutrients and, therefore, is sensitive to touch resulting radiating pain on palpation.
Introducing an acupuncture needle, activates central nervous system, thus a regeneration process of the damaged muscle. Puncture causes an involuntary contraction with the aim of muscle relaxation and the disappearance of both the local and the radiating pain.
