Dry Needling

A Comprehensive Guide to Its Mechanism, Benefits, and Applications

Dry needling is a powerful tool in the treatment of musculoskeletal pain and dysfunction. You may have heard of this therapy and wondered if it’s right for you.

While the name of the procedure may sound intimidating, dry needling is an accessible and commonly offered therapy that targets and releases trigger points within muscles, improving blood flow, reducing pain, and enhancing mobility.

This guide provides an in-depth look at dry needling, how it works, its benefits, comparisons with acupuncture, and the latest research supporting its effectiveness.

Dry needling can be a game-changer in improving your quality of life by effectively managing pain and enhancing physical function.

Although generally safe, the procedure should be performed by trained professionals such as allied health practitioners to minimise risks and maximise benefits. Always ensure that you receive treatment from a qualified and experienced provider to achieve the best possible outcomes.

What is Dry Needling?

Understanding Dry Needling: A Detailed Overview of This Effective Pain Management Technique

Dry needling is a specialised technique used by healthcare professionals, including physical therapists and acupuncturists, to treat musculoskeletal pain and movement impairments. The method involves inserting thin, sharp monofilament needles into areas of muscle known as myofascial trigger points—knotted, tender areas within the muscles that can cause pain and restrict movement.

Unlike trigger point injections, dry needling doesn’t involve injecting any medication; hence, it is referred to as “dry.”

During a dry needling treatment, one or more thin, monofilament needles are inserted into a muscle trigger point. A trigger point is a local band of tight, irritable, and dysfunctional muscle tissue, often emerging due to injury, overuse, or poor movement patterns. Trigger points can disrupt muscle function, restrict range of motion, or cause pain and tenderness.

Allied health practitioners perform an in-depth evaluation to determine if dry needling is appropriate. They assess mobility and muscle function to identify if trigger points are contributing to your symptoms.

When dry needling is applied to an affected muscle or trigger point, it can:

  • Decrease Muscle Tightness: Alleviates tension within the muscle fibres.
  • Increase Blood Flow: Enhances circulation to the treated area, promoting healing.
  • Reduce Pain: Lowers both local and referred pain, providing relief.

 

Patients often report immediate relief after treatment. The needles remain in your muscle for a short period—between 10 seconds and 20 minutes—depending on the treatment location, number of needles used, and treatment goals.

Dry needling is often paired with exercise and other soft tissue techniques to prevent trigger points from reoccurring.

How Does Dry Needling Work?

How Dry Needling Alleviates Pain & Improves Muscle Function

When muscles are overused, they can enter an energy crisis where they don’t receive enough blood supply, leading to pain and tightness. This inadequate blood flow results in an acidic environment around the trigger points, sensitising nerves and causing soreness and pain. Dry needling addresses this by:

  1. Increasing Blood Flow: The insertion of needles stimulates increased circulation, bringing oxygen and nutrients essential for muscle recovery and pain relief.

  2. Releasing Muscle Tension: Provoking a “local twitch response”—a brief muscle contraction triggered by the needle—helps reset the muscle to its normal resting state, alleviating tightness and pain.

  3. Modulating Pain Signals: The needle insertion can disrupt pain signals being sent to the brain and may stimulate the release of endorphins, the body’s natural pain relievers.

Once your practitioner locates a trigger point, they’ll insert a needle through your skin directly into it. They might move the needle slightly to elicit a twitch response, indicating the muscle is reacting positively to the treatment.

Some people feel improvement in their pain and mobility almost immediately after a dry needling session, while others may require multiple sessions for optimal results.

  • Sports Injuries: Commonly used to treat muscle strains, sprains, and overuse injuries among athletes, expediting recovery and improving performance.

  • Joint and Spinal Issues: Beneficial for conditions like TMJ disorders, carpal tunnel syndrome, and various spinal problems where muscle tightness and trigger points contribute to pain and dysfunction.

  • Other Conditions: Includes shoulder pain, rotator cuff pain, biceps tendinitis, iliotibial band syndrome, Achilles tendinitis, whiplash, neck pain, muscle strains, hip pain, temporomandibular pain (TMJ), and more.

What to Expect During a Dry Needling Session

From Start to Finish: What to Expect During Your Dry Needling Treatment

Before the Treatment

  1. Evaluation: Your provider will review your medical history and perform a physical exam to determine if dry needling is appropriate.

  2. Discussion: They will discuss your symptoms, assess mobility, and evaluate muscle function to identify trigger points.

During the Treatment

  1. Skin Prep: The treatment area is cleaned using alcohol swabs to minimise infection risks.

  2. Needle Insertion: Thin, single-use needles are inserted into the identified trigger points. The depth and technique may vary:

    • Superficial: Inserting the needle 5 to 10 millimeters into the subcutaneous tissue.
    • Deep: Inserting the needle beyond the subcutaneous tissue into the muscle to reach the trigger point.
  3. Needle Manipulation: The provider may gently move the needle to elicit a local twitch response, indicating muscle reaction.

  4. Duration: Needles may remain in place for as short as two seconds to as long as 20 minutes, depending on the treatment goals.

  5. Additional Techniques: The pistoning (in-and-out) technique may be used, or electrical stimulation may be applied to enhance muscle relaxation.

After the Treatment

  1. Needle Removal: Needles are safely disposed of in medical sharps containers.

  2. Post-Treatment Assessment: Your provider will check for any immediate reactions and ensure you are feeling stable before leaving.

  3. Self-Care: Drink plenty of water to stay hydrated. You may experience increased muscle soreness or bruising near the insertion sites, which typically resolves within 24 to 36 hours. Continue with recommended exercises and stretches to maintain the benefits of the treatment.

Dry Needling vs. Acupuncture

Key Differences and Similarities

While both dry needling and acupuncture involve inserting needles into the skin, they are distinct practices with different underlying philosophies and techniques.

Similarities

  • Use of Needles: Both techniques use thin needles inserted at various depths to treat symptoms.

  • Manipulation of Needles: Practitioners may gently move or manipulate the needles after placement.

  • Safety and Integration: Both are considered safe treatments and are often part of a larger treatment plan.

Differences

  • Philosophical Foundations:

    • Dry Needling: Rooted in Western medicine, focusing on treating musculoskeletal pain by targeting specific trigger points within the muscle tissue.
    • Acupuncture: Based on Eastern medicine, aiming to balance the flow of energy or life force (Qi) through pathways called meridians to treat a broader range of physical and mental conditions.
  • Training and Practice:

    • Dry Needling: Performed by allied health practitioners such as massage therapists, physiotherapists, chiropractors and  acupuncturists who are trained specifically in the procedure.
    • Acupuncture: Performed exclusively by licensed acupuncturists with training in traditional Chinese medicine.
  • Treatment Goals:

    • Dry Needling: Targets dysfunctional muscle trigger points to reduce pain, inactivate trigger points, and improve movement.
    • Acupuncture: Aims to restore energy flow, promoting overall health and treating conditions like pain, fatigue, infertility, headache, insomnia, anxiety, and depression.
  • Needle Usage:

    • Dry Needling: Typically uses fewer needles, sometimes paired with electrical stimulation to enhance treatment effects.
    • Acupuncture: Typically involves placing multiple needles along specific meridians and may incorporate moxibustion, a technique where the needles are gently heated to enhance therapeutic effects.

Frequently Asked Questions (FAQs)

While trigger points are usually painful to the touch, the insertion of needles may cause mild discomfort or a prick sensation. Some patients experience a local twitch response, which can be slightly painful but indicates muscle reaction. Post-treatment soreness or tightness is common but typically resolves within a few days.

The number of sessions varies depending on the individual’s condition and response to treatment. Some may experience immediate relief, while others may require multiple sessions to achieve optimal results.

Yes, dry needling is often part of a comprehensive treatment plan that includes exercise, stretching, massage, and other physiotherapeutic techniques to prevent trigger points from reoccurring.

While dry needling is generally considered safe when performed by qualified allied health practitioners, there are potential risks and side effects to be aware of:

Common Side Effects

  • Soreness and Bruising: Mild soreness or bruising at the needle insertion sites is common and usually resolves within a few days.

  • Stiffness and Fatigue: Some patients may experience temporary stiffness or fatigue post-treatment.

  • Fainting: Rarely, patients may feel dizzy or faint during or after the procedure.

 

Rare but Serious Risks

  • Infection: Although rare, improper sterilisation of needles can lead to infections however this risk is reduced with the use of disposable needles and the use of alcohol swabs at the site of needle insertions. 

  • Pneumothorax (Collapsed Lung): Extremely rare but can occur if needles are inserted too deeply near the thoracic (chest) area. Immediate medical attention is required if symptoms arise.

  • Nerve Injury: Potential risk if needles inadvertently contact nerves, emphasising the importance of having the procedure performed by a qualified practitioner.

 

Safety Tips

  • Ensure you consult a qualified allied health practitioner.
