What Is It?
Trigger Point Dry Needling (TPDN) is a physiotherapy technique used to treat muscle pain and movement problems.
It involves inserting a very fine, sterile, single-use needle into specific points within a muscle known as trigger points. These are often described as tight “knots” that can cause pain in the area or refer pain to other parts of the body.
The term “dry” simply means that no medication is injected — the needle itself is the treatment.
Although TPDN uses the same style of fine filament needle as acupuncture, the similarity largely ends there. Acupuncture is based on traditional Chinese medicine and aims to influence energy pathways (“Qi”) along meridians.
Dry needling, however, is grounded in modern Western medicine. It is based on anatomy, neurophysiology and current pain science, and directly targets dysfunction in the neuromuscular system.
TPDN aims to:
- Reduce muscle tightness
- Improve joint mobility
- Decrease pain and irritation
- Restore normal muscle function
It is commonly used by Australian physiotherapists to assist in managing neck and back pain, headaches, shoulder and hip pain, tendon pain and sports injuries. It is typically part of a broader treatment plan that may include exercise, manual therapy, education and activity modification.
How Does It Work?
Active trigger points have been shown in research to contain:
- Increased spontaneous electrical activity (overactive nerve signalling)
- Elevated inflammatory and pain-producing chemicals
This can be thought of as a “buzzing” or overactive nerve-muscle connection that keeps the muscle tight. Ongoing tightness can restrict joint movement and reduce normal function.
When the needle is inserted into a trigger point, it may produce a brief involuntary twitch response (called a local twitch response). This response:
- Helps reduce abnormal electrical activity
- Assists in normalising the muscle contraction
- Reduces local chemical irritation
- Allows the muscle to relax
Many patients feel a brief cramping sensation during this twitch, followed by reduced pain and improved movement.
By reducing muscle dysfunction more quickly, TPDN can help patients progress faster into strengthening and rehabilitation, supporting an earlier return to normal activity.
What Conditions Can It Help With?
Dry needling may assist in managing:
- Neck, back and shoulder pain
- Muscle strains and tightness
- Tendinopathies (e.g. tennis or golfer’s elbow)
- Headaches related to muscle tension
- Hip, calf or leg pain
- Restricted movement or stiffness
- Sports-related injuries
Your physiotherapist will determine whether dry needling is appropriate for your specific condition.
What Should I Expect During a Session?
- Your physiotherapist will assess and identify trigger points.
- The needle is inserted into the muscle — most people feel minimal sensation on insertion.
- You may feel a brief twitch or cramping sensation.
- Treatment typically lasts 10–20 minutes.
Some soreness afterward is normal and usually settles within 24–48 hours.
What Are The Benefits?
Potential benefits include:
- Reduced muscle pain and tightness
- Improved range of motion
- Better muscle activation and function
- Faster progression into strengthening exercises
- Improved overall rehabilitation outcomes
Research supports dry needling as an effective adjunct treatment for reducing trigger point–related pain when combined with physiotherapy management.
What Are The Risks and Side Effects?
Dry needling is generally safe when performed by a trained physiotherapist. However, as with any procedure, there are potential side effects.
Common (Mild and Short-Term)
- Temporary muscle soreness
- Minor bleeding
- Small bruises
- Mild discomfort
- Fatigue or heaviness
These usually resolve within 24–48 hours.
Less Common
- Dizziness or fainting
- Ongoing irritation
Rare
Very rarely, more serious complications may occur, such as infection or injury to underlying structures (for example, pneumothorax when treating areas near the ribcage).
Your physiotherapist is trained to minimise these risks through appropriate assessment, anatomical knowledge, sterile technique and safe clinical practice.
When Should Dry Needling Not Be Performed?
(In accordance with APA and AHPRA professional standards)
Dry needling is performed by appropriately trained physiotherapists within their scope of practice. A comprehensive assessment and informed consent process occurs prior to treatment.
Absolute Contraindications
Dry needling will not be performed if there is:
- Lack of informed consent
- Local infection at the needle site
- Active systemic infection or fever
- Uncontrolled bleeding disorder
- Inability to safely cooperate with the procedure
- Inadequate clinician training for the anatomical region
Relative Contraindications / Precautions
Additional care, modification, or medical clearance may be required if you have:
- Anticoagulant therapy or bleeding disorders
- Compromised immune function
- Poorly controlled diabetes
- Pregnancy
- History of fainting or severe needle phobia
- Epilepsy
- Recent surgery or acute trauma
- Lymphoedema or risk of lymphoedema
- Metal implants or joint replacements
- Severe osteoporosis
- Altered sensation
- Significant cardiopulmonary conditions
Is Dry Needling Safe During Pregnancy
We do not perform dry needling during the first trimester of pregnancy.
After the first trimester, dry needling may be considered in certain situations. However, specific anatomical regions and points will be avoided as an additional safety precaution.
If you are pregnant or unsure, please discuss this with your physiotherapist so we can determine the safest treatment approach for you.
What Should I Do After Treatment
You may experience mild soreness or fatigue in the treated area for 24–48 hours.
To assist recovery:
- Keep gently moving
- Stay hydrated
- Follow your prescribed exercises
If you experience increasing pain, swelling, shortness of breath, fever, or unusual symptoms, contact your physiotherapist promptly.
