Dry Needling

Introduction

Dry needling is a modern, evidence-based physiotherapy technique used to treat muscle pain, tightness, trigger points, and movement restriction. It involves inserting a very thin, sterile solid-filament needle, similar to an acupuncture needle but used within a Western musculoskeletal framework, into specific areas of muscle called myofascial trigger points. These are tight, sensitive knots within a muscle band that often cause pain locally or refer pain elsewhere in the body, and they're a common driver of persistent muscle tension, headaches, and chronic pain patterns.

Unlike an injection, no medication or fluid is introduced. The needle itself provides the therapeutic effect by stimulating the muscle fibre, connective tissue, and nervous system. Patients often feel a brief local twitch response as the needle contacts a trigger point, this is normal, expected, and part of how the technique works. Dry needling is sometimes also called intramuscular stimulation (IMS), trigger point dry needling, or muscle needling. The underlying principle is the same across these terms.

Dry needling has become one of the most widely used adjunct techniques in physiotherapy practice in South Africa and internationally, particularly for conditions where muscle tension, trigger points, and neuromuscular dysfunction contribute to pain. In Pretoria, it's used for everything from chronic neck pain and tension headaches to sports injuries, back pain and sciatica, and post-injury muscle guarding.

At Peak Physiotherapy in Mayville, dry needling is performed by James Muirhead Harris, who holds an ODNS (Optimal Dry Needling Solutions) Level 1 certification, a recognised training standard for physiotherapists practising dry needling in South Africa, accredited for continuing professional development (CPD) by the South African Society of Physiotherapy (SASP). It's included within your physiotherapy session as part of a broader assessment and treatment plan, rather than booked as an isolated standalone service. That matters clinically. Dry needling works best when it's targeted to specific findings from a full physical assessment, and paired with the exercise, mobility work, and load management that actually create lasting change.

Where Did Dry Needling Originate?

Dry needling developed from Western medical research into myofascial trigger points, first described in detail by Dr Janet Travell and Dr David Simons in the mid-20th century. Their work laid the foundation for understanding how dysfunctional muscle tissue can contribute to pain, weakness, and altered movement patterns.

Over time, physiotherapists refined dry needling into a clinically precise technique that fits within modern musculoskeletal rehabilitation. Today, it is used worldwide as part of an evidence-based physiotherapy treatment plan rather than a standalone therapy.

In South Africa, dry needling has been formalised through structured training pathways like the ODNS certification, which brings the technique into line with international best practice and integrates it within physiotherapy scope of practice rather than as a separate discipline.

Dry Needling vs Acupuncture

Although dry needling and acupuncture both use very thin needles, they are based on different philosophies and clinical goals. Dry needling is rooted in Western medicine, anatomy, and modern pain science. It targets specific muscles and neuromuscular structures identified during a detailed physical assessment.

Acupuncture, by contrast, originates from Traditional Chinese Medicine and focuses on influencing energy flow (Qi) along meridians. Dry needling is diagnosis-driven and movement-focused, making it particularly well suited to physiotherapy-based injury management and rehabilitation.

The differences show up most clearly in five areas:

Framework. Dry needling is rooted in Western anatomy, neuroscience, and pain science. Acupuncture is rooted in Traditional Chinese Medicine and the concept of Qi flow along meridians.

Assessment. Dry needling is diagnosis-led. Needles are placed based on a physical examination that identifies specific muscles, trigger points, or referred-pain patterns. Acupuncture point selection follows meridian mapping.

Practitioner. In South Africa, dry needling is performed by physiotherapists with specific training (like ODNS certification). Acupuncture is typically performed by acupuncturists registered under the Allied Health Professions Council of South Africa, or by medical doctors with acupuncture training.

Session context. Dry needling is almost always used within a broader physiotherapy session that includes assessment, exercise, and manual therapy. Acupuncture is more often a standalone treatment session.

Sensation. Both use similar needles, but dry needling deliberately elicits a local twitch response in the target muscle. Acupuncture typically doesn't.

Both approaches have their place. If you're looking for musculoskeletal rehabilitation, movement restoration, or return-to-sport work, dry needling within physiotherapy is the fit. If you're looking for whole-system acupuncture based on TCM principles, an acupuncturist is the appropriate referral.

How Dry Needling Works

Dry needling targets myofascial trigger points: small, hyperirritable bands within a muscle that stay contracted even when the rest of the muscle is relaxed. Inserting a thin needle directly into this band typically produces a local twitch response, a brief, involuntary contraction that's thought to help interrupt the abnormal muscle activity holding the trigger point in place.

This mechanical effect is combined with changes at the nervous system level: needling appears to influence local blood flow and alter how pain signals from that area are processed, contributing to reduced sensitivity and muscle tension in the hours and days that follow.

Evidence & Research Support

Research on dry needling has expanded substantially over the past 15 years, and the current evidence base supports its use as an adjunct within physiotherapy rehabilitation, particularly when combined with exercise and movement retraining, rather than used in isolation. Systematic reviews consistently find that dry needling can reduce pain and improve function in conditions like chronic neck pain, plantar heel pain, tension-type headache, shoulder pain, and lower back pain, especially in the short to medium term.

The clearest signal in the research is that dry needling works best as part of a broader treatment plan, not as a standalone therapy. Studies comparing dry needling alone to dry needling plus structured exercise consistently show that the combination outperforms either intervention on its own. This is why dry needling at Peak Physiotherapy is always applied within a full session that includes exercise prescription, manual therapy, and rehabilitation planning.

Individual response to dry needling varies. Some patients experience a marked reduction in muscle tension and pain sensitivity within one or two sessions, while others need several sessions before a clear response emerges. Some presentations respond very well to needling, and some don't respond much at all. That's normal, and it's part of why we assess after each session and adjust the treatment approach based on what your body is actually responding to, rather than pushing a fixed protocol.

Benefits of Dry Needling

When it's the right fit, dry needling offers several benefits within your broader treatment plan:

• Pain reduction: helps desensitise overactive muscles and reduce pain signalling
• Improved flexibility: allows tight or shortened muscles to relax more effectively
• Better movement: supports smoother, more efficient movement patterns
• Enhanced rehab: makes strengthening exercises more comfortable and effective
• Reduced protective muscle guarding: helping interrupt the pain-tension-avoidance-deconditioning cycle that keeps chronic muscle pain going

What to Expect During a Session

During a dry needling session, your physiotherapist will first assess your posture, movement, and muscle function to identify problem areas: the specific muscles that are tight, tender, or driving your pain. This assessment is what distinguishes physiotherapy dry needling from generic needle work: the needles go where the clinical findings point, not to a preset pattern.

Fine, sterile, single-use needles are then inserted into specific tight muscle bands. You may experience:

• A brief aching, cramping, or twitch response as the needle contacts a trigger point
• Temporary local soreness after the session, similar to post-exercise muscle soreness
• A sense of muscle release or reduced tension as the trigger point desensitises
• Occasionally, a light sensation of referred pain, pain that travels to another area, which can actually help confirm the correct muscle is being treated

These responses are normal and usually settle within 24–48 hours. Most patients are comfortable driving home afterwards and returning to normal activity, though we generally recommend avoiding heavy training on the same day. Dry needling is almost always combined with exercise therapy, movement retraining, and manual therapy within the session. The needling isn't the whole treatment, it's one tool.

A typical dry needling application takes 5–15 minutes within a broader physiotherapy session. The number of needles used varies. Sometimes one or two targeting a single problem area, sometimes more spread across several muscles depending on the presentation.

Conditions & Clinical Uses

How Dry Needling Fits into Your Treatment Plan

Dry needling on its own doesn't fix underlying movement problems, strength deficits, or the loading habits that produced the muscle tension in the first place. That's why it's applied within a physiotherapy session that includes:

• A physical assessment to identify what's actually driving your symptoms
• Manual therapy techniques such as joint mobilisations or myofascial release where indicated
• Exercise prescription targeted to your specific findings and goals
• Movement retraining and load management guidance
• Education about what to expect and how to progress

Dry needling adds a specific tool for muscle-driven symptoms. The rest of the session addresses everything else.
