To perform this technique, needles similar to those of acupuncture are inserted, but slightly larger and directly on the trigger point, producing muscle relaxation and reducing the contracture of the affected area. This also helps the flow of nutrients to the muscle to promote tissue regeneration.
Muscle pain is a common symptom that affects everyone. It is usually responsible for discomfort ranging from mild to severe intensity depending on the reason for the damage. Generally, it occurs due to muscle overload during physical exertion or exercise, and disappears on its own after a few days.
On other occasions, muscle pain is the product of the formation of some myofascial trigger point, contracture. These points do not usually disappear by themselves and require the help of heating treatment, by means of massage and stretching for their normalization.
Trigger points are hyper irritable areas in the muscles, which cause pain when pressed, stretched or contracted. Generally, trigger points are latent, requiring a physical stimulus for a painful response to occur. However, on some occasions, trigger points can be active and spontaneously generate pain without any stimulation or contact.
These points are produced when the muscle fibers of a certain place remain permanently contracted, creating a hypersensitive nodule that decreases blood flow and prevents oxygenation of the area, producing the painful response. When the needle penetrates the trigger point, the muscle fibers relax, eliminating contraction and promoting adequate blood supply and nutrient flow to the area in order to heal the affected muscle and eliminate discomfort. However, there may be a slight post-puncture discomfort that disappears after a short time.
