This study evaluates the deep dry needling technique as a percutaneous technique included in the professional field of physiotherapy.
The project quantifies a significant limit on the number of local twitch responses necessary for the favorable treatment of myofascial pain and analyzes the injury degree and/or the repair of myofascial tissue, with "Elastography".
Full description
The myofascial shoulder pain caused by myofascial trigger points, is one of the main causes of medical consultation and functional disability in the general population and particularly in the amateur athlete.
Nowadays, many physiotherapists all over the world, study and practice the dry needling as a therapeutic tool for the treatment of myofascial trigger points. The most used modality is the technique described by Hong:
The dry needling technique, in its eagerness to obtain local twitch responses, pierces the muscle fibers both dysfunctional and normal, the fascial tissue that wraps the myofascial trigger points and also neuro-vascular structures. That is, the treatment of myofascial trigger points with dry needling, makes reference to a mechanical trauma done with a acupuncture needle.
The myofascial tissue injured can suffer repair or regeneration, which is mainly due to the extension of the lesion. The process of healing of a wound is strictly regulated by multiple growth factors and cytokines, which are released into the wound. The alterations that disturb the healing process, can lead to chronic wounds that do not heal or to an excessive fibrosis.
The pathobiological processes, in form of fibrosis, would present changes in stiffness and elasticity of the neo-tissue. The quantitative elastography, is shown as an effective tool to measure the amount of fibrosis, occasioned by repeated percussion of the acupuncture needle on the myofascial tissue.
