What is Dry Needling?
Dry Needling is a treatment technique whereby a sterile, single-use, fine filament needle (acupuncture needle) is inserted into the muscle to assist with decreasing pain and imp-roving function through the release of myofascial trigger points (knots in the muscle).
What is the Difference Between Dry Needling and Acupuncture?
Dry Needling is a not the same as acupuncture, although there are similarities between the two techniques. The main difference between Dry Needling and acupuncture is the theory behind why the techniques work. Dry Needling is primarily focused on the re-duction of pain and restoration of function through the release of myofascial trigger po-ints in muscle. In comparison, acupuncture focuses on the treatment of medical conditi-ons by restoring the flow of energy (Qi) through key points in the body (meridians) to restore balance.
What is a Myofascial Trigger Point?
A myofascial trigger point, also known as a knot in the muscle, is a group of muscle fibres which have shortened when activated but have not been able to lengthen back to a relaxed state after use. A myofascial trigger point is characterized by the development of a sensitive nodule in the muscle (Simons, Travell & Simons, 1999). This occurs as the muscle fibres become so tight that they compress the capillaries and nerves that supply them (McPartland, 2004; Simons, et al., 1999). As a result, the muscle is unable to move normally, obtain a fresh blood supply containing oxygen and nutrients, or flush out addi-tional acidic chemicals (McPartland, 2004; Simons, et al., 1999). In addition to this no-dule, the remainder of the muscle also tightens to compensate (Simons, et al., 1999; Si-mons, 2002). The presence of a myofascial trigger point in a muscle can lead to discom-fort with touch, movement and stretching; to decreased movement at a joint; and even a temporary loss of coordination (Simons, et al., 1999).
What Causes a Myofascial Trigger Point?
A myofascial trigger point develops as part of the body’s protective response following:
• injury – the muscle will tighten in an attempt to reduce the severity of an injury;
• unexpected movements e.g. descending a step that is lower than originally antici-pated;
• quick movements e.g. looking over your shoulder while driving;
• change in regular activity or muscle loading e.g. an increase in the number or in-tensity of training sessions for sport;
• sustained postures e.g. prolonged sitting for work or study;
• nerve impingement – the muscle will tighten to protect the nerve;
• illness (bacterial or viral);
• nutritional deficiencies, or;
• metabolic and endocrine conditions.
(Simons, et al., 1999)
How does Dry Needling Work?
Dry Needling assists with decreasing local muscular pain and improving function thro-ugh the restoration of a muscle’s ability to lengthen and shorten normally by releasing myofascial trigger points.
When a fine filament needle is inserted into the center of a myofascial trigger point, blo-od pools around the needle triggering the contracted muscle fibers to relax by providing those fibers with fresh oxygen and nutrients, as well as by flushing away any additional acidic chemicals. This, in turn, leads to the decompression of the local blood and nerve supply.
When is it Appropriate to Use Dry Needling as a Form of Treatment?
Dry Needling can be used in treatment:
• to help release myofascial trigger points (muscle knots);
• to assist with pain management, and;
• to restore movement at a joint if inhibited by myofascial trigger points.
What Will You Feel During Dry Needling Treatment?
During a Dry Needling treatment, you may feel a slight sting as the needle is inserted and removed. However, this discomfort should last no longer than a second before sett-ling.
A brief muscle twitch can also be experienced during a Dry Needling treatment. This may occur during treatment when the needle is inserted into a myofascial trigger point.
Where Does Dry Needling Fit Within Your Rehabilitation Program?
Dry Needling is one of many techniques that can be utilized by your physiotherapist to assist with your rehabilitation. Dry Needling is often used in combination with other techniques including massage, manual therapy, and exercise prescription.
What are the Side Effects of Dry Needling?
Every form of treatment can carry associated risk. Your physiotherapist can explain the risks and can determine whether Dry Needling is suitable for you based on your injury and your general health.
When Dry Needling is performed, single-use, sterile needles are always used and dispos-ed of immediately after use into a certified sharps container.
Is Dry Needling Safe?
Everybody is different and can respond differently to various treatment techniques, inc-luding Dry Needling. In addition to the benefits that Dry Needling can provide, there are a number of side effects that may occur, including spotting or bruising, fainting, nausea, residual discomfort or even altered energy levels. However, these symptoms should last no longer than 24 to 48 hours after treatment.
Can You Exercise After Dry Needling?
It is recommended to avoid strenuous or high impact activities immediately after Dry Needling, to allow the body time to recover, and to maximize the benefits of the tre-atment.
