Dry needling is a treatment technique that evolved from the work of Dr. Janet Travell and David G. Simons. Their pioneering work lead to the evolution of modern dry needling. It involves the insertion of very fine needles into a trigger point (tight muscle band) to illicit a local twitch response from the painful muscle.
There are a number of suggested mechanisms by which trigger point dry needling works. The introduction of the needle leads to an immune response in the affected area. The micro trauma leads to a fresh supply of oxygen and nutrients to promote healing. It also affects the nerves and the information they send to the painful muscle by downregulating the information sent which helps relax the muscle.
For maximum benefit this unique treatment approach should be used in conjunction with other conventional physiotherapy treatment options.
