Dry needling is the application of needles at specific sites in the body to stimulate surrounding tissue. It is aimed to elicit mechanical stimulation thus improving function and pain.
Dry needling works by initiating an inflammatory response when the needle is inserted at trigger points. This inflammatory response releases chemicals which increases blood flow, allowing healing cells to help repair damaged tissue. When the needle is pulled out, the tissue cells and collagen damaged need to be regenerated and relayed.
The renewed tissues enable more movement as there is less pain in the needled area.
