Biomedical dry needling can be thought of as more of a Western-medicine approach to acupuncture. Dry needling treats the direct source of pain, whether it be muscles, nerves, tendons, or ligaments. For example, needles are used at myofascial trigger points, or knots, that are causing pain or discomfort. Insertion of a needle causes a local twitch response that results in reduced pain, increased circulation and muscle stimulation of the muscles and overlying fascia. This technique is often used to help break the pain cycle and promote healing in conjunction with additional treatment modalities.
