Functional Dry Needling is a treatment technique performed by a manual therapist who has documented competencies determined by the State of Colorado. Dry needling is performed using a sterile, single use, mono filament fine needle inserted into a muscle or trigger point, as well as relevant spinal segments for the purpose of affecting change in body structures, managing neuromusculoskeletal conditions, reducing pain and movement impairment. Dry Needling, with or without electrical stimulation, improves blood flow and immune mediators, reduces H ions and releases tight bands known as myofascial trigger points. Therefore the technique provides physiological, biomechanical, and chemical changes as treatment for acute and chronic pathology and often times can be dramatic and immediate.
