It is called dry needling in order to emphasize the fact that no chemical agents are used and distinguish it from other invasive techniques using substance infiltration.
The treatment of dry needling is used more frequently in Myofascial pain syndrome.
Myofascial Pain Syndrome (SDM) can be defined as the pain that originates in the
muscle or in the muscular fascia and includes a series of conditions that cause regional or referred pain and shortening of the muscle fiber producing restrictions in the normal mobility of the muscle and preventing the necessary nutrients from reaching the muscle.
It is a noninflammatory disorder manifested by localized pain and stiffness. Its main characteristic is the presence of “trigger points” that can be identified as thickened nodules inside the muscle or the fascia that, when pressed, trigger the symptomatology.
Dry needling is an invasive treatment that consists of puncturing these “trigger points” in order to deactivate them, thus initiating a process of regeneration of the damaged muscle that will facilitate the arrival of the needed nutrients and newly synthesized proteins. During treatment, local spasm responses (involuntary muscle contractions) occur. After the puncture, the muscle relaxes and decreases the local and referred pain, thus producing an improvement in the functionality of the patient.
