Dry Needling vs. Acupuncture: What's the Difference and Does It Work?

Understanding Dry Needling

Physiotherapists, chiropractors, and osteopaths commonly use dry needling to treat neck, shoulder, back, and other types of muscle pain. The technique involves inserting thin needles into sensitive parts of a muscle, often termed "myofascial trigger points." The needles remain in the muscle for a few minutes and can be gently moved to create a twitch response in the muscle. This therapy is thought to relax the muscle, reduce inflammation, promote healing, and reduce pain.

Similarities and Differences to Acupuncture

Dry needling is similar to acupuncture: both are used to reduce pain. Both treatments use solid, single-use needles, commonly 30–75mm long and 0.2–0.3mm thick, although longer needles may be used for deeper muscles. Unlike injection needles, they aren't hollow and don't inject medication.

A key difference is how the needle locations are chosen. Traditional acupuncture selects points based on symptoms and Chinese medicine concepts, including balancing qi as it flows through pathways called meridians. Dry needling is applied directly to tissue that's thought to be the cause of symptoms.

Growing Popularity of Dry Needling

People seeing a physiotherapist for aches and pains are increasingly being offered dry needling. A 2023 survey of 203 Australian physiotherapists found that 64% use dry needling on their patients. The surveyed physiotherapists believed dry needling was an effective pain reliever and thought it was particularly effective alongside treatments such as exercise or manual therapy (which encompasses massage and manipulation or "joint cracking").

In Australia, registered physiotherapists, chiropractors, and osteopaths meet the safety standards required to use dry needling if they have completed training. The training usually involves a short (weekend) course.

Does Dry Needling Work?

Several research studies have collated the available evidence on dry needling. Most conclude it provides short-term pain relief for conditions such as neck pain, shoulder pain, and low back pain but is no better than other treatments. The evidence for long-term benefits is limited, and more rigorous studies are needed to confirm its effectiveness. Some patients report immediate relief, but the scientific basis for its mechanism remains debated.

Risks and Side Effects

Like any procedure involving needles, dry needling carries some risks. Common side effects include soreness, bruising, and bleeding at the needle site. More serious complications, such as infection or nerve damage, are rare but possible. It is essential that the practitioner is properly trained and uses sterile, single-use needles to minimize risks.

What Patients Should Consider

If you are considering dry needling, it is important to discuss it with your healthcare provider. Ensure that your practitioner is qualified and experienced. Dry needling may be offered as part of a comprehensive treatment plan that includes exercise and other therapies. While it may provide short-term relief, it is not a cure-all, and its long-term effectiveness is still under investigation.

Conclusion

Dry needling is a popular technique used by many physiotherapists, chiropractors, and osteopaths. It differs from acupuncture in its theoretical basis and application. While some evidence supports its short-term benefits for muscle pain, more research is needed to establish its long-term efficacy and safety. As with any medical treatment, informed consent and professional practice are key.
