What is Dry Needling?
Dry needling is a therapeutic technique involving the insertion of a very fine needle into various tissues, such as muscles, fascia, ligaments, and tendons, to normalize muscle tension, reduce pain, and improve function. While commonly used by trained physiotherapists to treat trigger points, dry needling is also effective in managing a wide range of musculoskeletal issues, including chronic tendon pain, joint dysfunction, muscle strains, and nerve-related conditions. The technique is usually performed at or near the site of pain but can also be applied to other areas to address broader musculoskeletal problems. It's important to note that dry needling is distinct from acupuncture, which is based on traditional Chinese medicine principles.
​
Why is it Called “Dry Needling?
The term "dry needling" differentiates this technique from "wet needling," which involves injecting substances such as corticosteroids (e.g., cortisone shots) into tissues using a syringe. In contrast, dry needling involves the insertion of needles without injecting any fluid, hence the term "dry."
​
Broader Applications of Dry Needling
Beyond treating trigger points—painful, taut bands of muscle—dry needling is used to address a variety of musculoskeletal conditions. These include chronic tendinopathies, joint dysfunction, muscle strains, and even nerve-related conditions. The technique can help reduce inflammation, promote healing, and restore normal movement patterns by targeting specific areas of dysfunction.
​
How Do Trigger Points Form?
Muscles should operate at an optimal length in coordination with other muscles. In a dysfunctional state, muscles may be overworking or underworking, contributing either too much or too little to a task. Factors such as muscle weakness, joint dysfunction, fatigue, poor posture, repetitive activities, and trauma can irritate muscles, leading to the development of trigger points. Often, trigger points are compensatory responses to other underlying problems.
​
How Does Dry Needling Work?
The exact mechanisms of dry needling are still being studied, but several hypotheses exist. When a needle is inserted into a targeted area, it may elicit a local twitch response—a brief contraction of the muscle—which is a sign of effective treatment. This response helps inactivate the trigger point and reduce muscle tension. Additionally, dry needling can improve blood flow and reduce the concentration of pain-related chemicals in the tissue, such as calcitonin gene-related peptide and substance P, facilitating the healing process.
​
Why are Trigger Points a Problem?
In response to long-standing pain, the body may develop maladaptive patterns, such as fear of movement, altered breathing, abnormal muscle activation, and anticipation of pain during certain activities. These patterns can contribute to persistent, complex pain. Trigger points, when untreated, may exacerbate these issues, making comprehensive treatment essential for lasting relief.
​
How Will I Feel After My Dry Needling Session?
The most common post-treatment symptom is soreness, often described as feeling similar to muscle soreness after a workout. Some patients liken the sensation to a bruise or "cork," which typically subsides within a day or two. Continuing to move normally as the soreness fades is recommended, and using athletic tape or taking a hot shower can help alleviate discomfort. Improved muscle performance and reduced tension are expected within days.
​
Is Dry Needling Painful?
The experience of pain during dry needling varies depending on several factors, including the method used by the physiotherapist, the individual’s pain tolerance, prior experiences with needles, and level of anxiety. The technique can be superficial or deep and may be combined with electrical stimulation to enhance the therapeutic effects. While some discomfort may occur, it is generally well-tolerated.
​
How Many Treatment Sessions Will I Need?
The number of sessions required depends on the condition being treated, the number of affected areas, and the duration of symptoms. Acute issues with only a few trigger points may resolve with a single session, while chronic conditions or multiple areas of dysfunction may require more extended treatment, sometimes up to 12-14 sessions.
​
Is Dry Needling Safe?
Dry needling is a clean and safe technique when performed by a trained physiotherapist. Sterile, single-use needles are always used, minimizing the risk of infection. The needles are very fine and flexible, so there is usually no bleeding, although a small droplet of blood or a minor bruise may occasionally occur.
​
Is Dry Needling Appropriate for Everyone?
Your physiotherapist will ensure you are an appropriate candidate for dry needling by discussing your medical history and current condition during your appointment. Physiotherapists are highly trained in anatomy, so the risk of injury associated with needling is extremely low.
​
Conclusion
Dry needling is a versatile technique that extends beyond trigger point therapy, offering benefits for a wide range of musculoskeletal conditions. Whether addressing chronic pain, joint dysfunction, or muscle strain, dry needling can be a valuable part of a comprehensive treatment plan. Your physiotherapist will tailor the approach to your specific needs, ensuring effective and safe outcomes.
