What is Dry Needling?

Dry needling is the process of inserting thin monofilament needles without the use of injectate to treat a variety of neuro-musculoskeletal conditions. The needles are inserted into muscles, tendons, osteotendinous junctions, joint capsules, fascia, scar tissue, epidermis, dermis, and perineural tissue to create a response at a chemical and cellular level. Once the needle is inserted, it is manually and/or electrically stimulated to elicit the desired tissue response.

 

Is dry needling the same as acupuncture?

The word acupuncture translates to “needle penetration.” The methods and procedures of acupuncture and dry needling are actually quite similar; however, the terminology, theoretical constructs, and philosophies are different. Dry needling is prescribed based on western musculoskeletal diagnoses, not within the theoretical framework of traditional Chinese medicine. Dry needling is used to create biomechanical, chemical, and vascular changes within the body. Unlike traditional Chinese acupuncture, the needles are not inserted with the intention of altering qi/ energy along traditional Chinese meridians. Dry needling is an evidence- based practice supported by local tissue response, how the nervous system relays this response to the brain, and how the brain interprets and responds to those signals.

 

What kind of needles are used?

A thin, monofilament needle is used to pierce the skin and enter the desired tissue. Each sterile disposable needle  comes in an individual plastic guide tube to provide a clean and safe treatment. Patients typically experience minimal pain from the needle breaking the skin due to pre-contact from the guide tube. The needles come in a variety of lengths ranging from 15 mm to 75 mm and are selected for use based on depth of target tissue.

 

How does Dry Needling work?

Dry needling creates biomechanical, chemical, and vascular changes throughout the body that ultimately reduce pain and restore function.

Reduce Pain

Dry needling simulates pathways that inhibit pain at the level of the tissue, spinal cord, and brain. Depending on how long you have been experiencing pain, changes can occur in any of these three structures, altering your perception of pain. The insertion and stimulation of needles into neuro-musculoskeletal structures can help reduce pain through a variety of biochemical mechanisms. 

Tissue Repair

Inserting needle into a dysfunctional tissue causes microtrauma within the tissue which kickstarts the inflammatory process. Acute inflammation is the first step in tissue repair. Therapists will often wind or twirl the needles after they are inserted. This mechanical stimulation changes the orientation and structure of cells leading to tissue remodeling.

Increase blood flow 

Chronic injuries or areas of pain, such as myofascial trigger points and tendinopathies, develop fibrous adhesions otherwise known as scar tissue. This scar tissue blocks neurovascular bundles inhibiting muscle function due to limited oxygen supply. Dry needling stimulates vasodilation and microcirculation to the surrounding area increasing blood supply, oxygen, and healing factors.

 

 

Is it painful?

Some areas of the body are more sensitive than others, but the piercing of the skin generally is not very painful. The pressure from the plastic guide tube dampens the feeling of the needle penetrating the skin. Once moderate pressure of the guide tube is applied to the skin, the monofilament needle is quickly tapped in. If the area being treated is more sensitive, there are other manual therapy techniques your physical therapist can use to decrease the sensation of the needle breaking skin. Once the needles are inserted, it is the therapist’s intent to create a deqi response. Literature describes deqi as a feeling of dull achiness, heaviness, distension, numbness, tingling, cramping, pressure, fullness, spreading, warmth, or coolness. This sensation may be felt right away or may be elicited by winding the needles or applying electrical stimulation to the needles.

 

 

How many sessions does it take to work?

Dry needling is a component of the physical therapy practice. It is used in conjunction with other manual therapy techniques and therapeutic exercise to treat neuro-musculoskeletal conditions. Research has yet to determine the optimal dosage including number of sessions per week or month and number of needles inserted. Studies do suggest needles that remain in situ, or in position, for 15-30 minutes are more effective than immediate removal. Do not expect one session to solve all your pain or muscle tension. Just like one workout will not make you stronger, one dry needling session will most likely not completely heal you either.

    1. Hi Jane, yes it can. The treatment can help reduce inflammation surrounding the nerve. The most effective plan would be dry needling to help manage pain and decrease inflammation followed by a strength training program to build strong resilient back 🙂
