Functional Dry Needling is a technique used to release tight muscle bands associated with trigger points or dysfunctional muscles that cause pain. Functional Dry Needling (FDN) uses acupuncture size needles to stimulate a neurological response in the muscle by activating the motor neuron. This treatment utilizes a thin solid filament needle to deactivate and desensitize the trigger points in muscles. Functional dry needling can also be used to facilitate dysfunctional muscles by applying electric current directly into the tissue.
