Dry needling refers to the use of needles for therapy of muscle pain such as myofascial pain syndrome. There are two types of acupuncture needles used in this process, that is, hollo-core hypodermic and solid filiform needles. This process is also sometimes referred to using the name intramuscular stimulation (IMS). Dry needling or IMS is one of the many subcategories (traditional practices) that are classified under western acupunctural medicine. Whenever there is need of professionals in dry needling Pennsylvania is the place to visit.

The Chinese version of tendinomuscular acupuncture relies on carefully palpating Ah Shi points which often correspond to both motor and trigger points in the myofascial tissue. As opposed to the Japanese and American styles which utilize higher gauge needles, the Chinese style makes use of lower gauge needles necessary for precise puncturing of contraction knots. Having a detailed knowledge of channel networks and connections and of the western anatomy is very crucial in most acupuncture styles.

As such, even though not all forms of acupuncture are covered under IMS and the two practices differ, some forms of acupuncture can be referred to specifically using the term IMS. Those forms include versions of Sports Acupuncture, tendinomuscular Acupuncture, and Myofascial Acupuncture. The term dry needling was first described in a book by a woman named Janet Travell. Thus, she is credited with coining the term.

Initially, there were concerns about the employment of solid needles. They were thought to lack the strength and tactile feedback that are provided by hypodermic needles. Solid needles were also thought as being easy to be deflected by dense contraction knots. However, those concerns were determined to be baseless and solid needles also called acupuncture needles are now being used.

In fact, it has been concluded by research that dense muscle knots are penetrated easier and better by acupuncture needles. They also give better tactile feedback and patients experience less discomfort. Acupuncture needle is the official FDA designation for the needles used. However, the technical design term, solid filiform needle, was introduced by practitioners whose scope of practice excludes acupuncture but allows them to offer IMS.

Currently, no standards for dry needling exist. There is also no body of evidence to indicate its efficacy in managing the medical conditions it claims. Most of the studies that were conducted on this technique were crowded by a lot of issues that made it impossible for any strong evidence to be gathered. For instance, sample sizes employed were small, drop out rates were high, and studies lacked randomization.

The studies failed to state if the pain the patient felt was solely caused by myofascial trigger points. Additionally, they did not adhere to minimally acceptable criteria that need to be followed to diagnose a myofascial trigger point. Drop out rates in some studies have been as high as 48 percent. However, research studies that continued to the end concluded that IMS can improve function, disability, and mood.

IMS is a treatment that is practiced and taught in many places worldwide. The teaching and practicing is done by various medical professionals including acupuncturists, physical therapists, doctors of osteopathic medicine, naturopathic physicians, doctors of medicine, and chiropractors among others. The scope of practice of acupuncturists, and Doctors of Medicine and Osteopathic Medicine covers IMS.
