Deep Dry Needling, also known as intramuscular stimulation (IMS), is a technique for therapy of muscle pain, including pain related to myofascial pain syndrome. A fine needle is inserted into the body’s soft tissue or muscle and surrounding fascia. This insertion may exhibit a local twitch response and facilitate release of a taught band in the muscle, relieve trigger points in the muscle, and facilitate muscle fibers to relax and stretch.

Superficial dry needling involves needle insertion to superficial tissue over a specifically affected area, such as a ligament or tendon, to promote healing.
