Dry Needling

Dry needling enables practitioners not only to defuse pain, but to help heal. Dry needling uses monofilament needles, which are also used in acupuncture. “Any similarity between acupuncture and dry needling is on the surface”, says Dr. David Fishkin, DC, MPH, founder of the Dry Needling Institute in Rockville, MD.

Dry needling speeds the process for healing sprains and muscle spasms, as does kinesiotaping.

How different are acupuncture and dry needling?

Dr. David Fishkin says dry needling (DN) is “a physiologic therapeutic technique and procedure. Its purpose is to neutralize soft tissue and to restore and improve muscle and fascial function. This treatment mechanically disrupts physiologically locked tissue. It consists of insertion of a monofilament, sterile, thin-gauge needle, a needle that also happens to be used by acupuncturists. Dry needling is not to be confused with acupuncture. Acupuncture is an Asian complete system of healing. Its theories focus on the use of specific points, meridians, and the concept of chi, or life-force.

The dry needling procedure, however, works with myofascial trigger points and tender points. It is based on Western concepts of anatomy, physiology, neurology, and biomechanics. The only common element is the choice of tool.”

What are the physiological and neurological mechanisms behind dry needling?

“Tissue becomes locked, fixated. We also use this term in chiropractic—when joints become fixated.” But that, says Dr. Fishkin, refers to bones. “With soft tissue, the muscle-fascial system is also in a locked or fixated state. The needle has to mechanically disrupt the area in a way similar to chiropractic manipulation to restore motion.” Dr. Fishkin says that with trigger points, too, the provider wants to allow fixation to dissipate. “I believe what’s happening is that dry needling improves lymphatic and blood circulation. pH levels improve. Interstitial swelling, which is associated with this process, recedes, and neuronoxious chemicals are flushed out. Whether it’s osseous manipulation or mobilization or massage, they all cause a response in the central system, meaning in the brain, as well. Needling will send signals to the spinal cord and up pathways to the brain, which appear to elicit a strong response from the hypothalamus, which then influences the pituitary and subsequent endocrine functions.

Is there always a spinal cord component to dry needling?

“In treatment, yes. But you can have a purely peripheral presentation. You can treat peripherally and it can result in complete resolution of the problem. So it’s not necessary to treat both. You can treat just peripherally.” But, Dr. Fishkin says, it’s often important to needle both a particular trigger point and the related paraspinals. “We may not be sure where the irritation started — centrally or peripherally. As we know, the communication goes both ways. Therefore, when there is a question, absolutely treat both. But there are times when someone will have a very localized area and you can just treat the spot and be done with it.”
“The important thing to me is that the patient has a minimally painful experience. Some other techniques are very uncomfortable for the patient. I’ve adapted and changed the approach to make it both as comfortable and as effective as possible.”
