What Is Dry Needling?
Dry needling — also called intramuscular stimulation (IMS) — is a technique used by trained physiotherapists to treat myofascial trigger points. These are hypersensitive, contracted knots within muscle tissue that cause local pain, referred pain, and restricted movement.
A thin, sterile needle (the same type used in acupuncture) is inserted directly into the trigger point. This produces a brief local twitch response in the muscle — a small, involuntary contraction that signals the release of the knot. The result is reduced muscle tension, decreased pain, and improved range of motion.
It's called "dry" needling because no medication is injected — the therapeutic effect comes entirely from the mechanical action of the needle itself.
What Is Electroacupuncture?
Electroacupuncture takes dry needling a step further by attaching a small electrical stimulator to the needles once they're in place. A gentle electrical current passes between pairs of needles, providing sustained stimulation to the muscle or nerve tissue.
This is particularly useful for chronic pain conditions, nerve-related pain (neuropathy), and cases where the muscle tension is stubborn and deeply ingrained. Many patients find electroacupuncture produces a deeper, longer-lasting effect than needling alone.
Conditions That Respond Well to Dry Needling
- Neck and upper trapezius tension
- Tension headaches and cervicogenic headaches
- Shoulder pain and rotator cuff conditions
- Low back pain and gluteal trigger points
- Tennis elbow (lateral epicondylitis)
- Plantar fasciitis and calf tightness
- IT band syndrome and knee pain
- Chronic myofascial pain that hasn't resolved with other treatment
- Post-injury muscle guarding and spasm
How Dry Needling Differs from Acupuncture
Both techniques use the same thin, filiform needles — but the philosophy and point selection are different. Traditional acupuncture is rooted in Chinese medicine and uses specific meridian points to influence the flow of qi (energy) through the body. Dry needling is purely anatomy-driven: it targets myofascial trigger points based on Western musculoskeletal science.
In practice, both approaches can be highly effective. At C.S. Physiotherapy, our team is trained in both — and we'll recommend whichever is best suited to your condition. See our acupuncture page for more on the traditional approach.
Performed by registered physiotherapists. Our dry needling is always performed as part of a comprehensive physiotherapy assessment and treatment plan — never as a standalone procedure. This ensures the technique is applied appropriately and safely.
What to Expect During Treatment
Dry needling sessions typically take 15–30 minutes and are performed as part of your broader physiotherapy appointment. Your physiotherapist will identify the relevant trigger points through hands-on assessment, then insert needles with precision. You may feel a brief, deep aching sensation — the local twitch response — which subsides quickly.
Mild soreness in the treated area is common for 24–48 hours after the session, similar to the feeling of a deep muscle massage. This is a normal part of the healing response. Most patients notice meaningful improvement in their pain and mobility within 2–4 sessions.
Frequently Asked Questions
Does dry needling hurt?
The needle insertion itself is usually barely noticeable. When the needle reaches a trigger point, you may feel a brief dull ache or muscle twitch — this is normal and a positive sign. Mild post-treatment soreness for a day or two is common.
How is dry needling different from acupuncture?
Dry needling targets myofascial trigger points based on anatomy and musculoskeletal science. Traditional acupuncture uses meridian-based point selection from Chinese medicine. Both use fine needles, but the theoretical basis and clinical application differ.
Is dry needling covered by my insurance?
When performed by a registered physiotherapist as part of physiotherapy treatment, it is typically covered under extended health plans. Coverage varies — check your policy or call us for guidance.
How many sessions will I need?
Most people see meaningful improvement within 2–6 sessions. Chronic or long-standing trigger point problems may require more. Your physiotherapist will give you a realistic expectation after your first assessment.
Is dry needling safe?
Yes. When performed by a trained clinician, dry needling is very safe. We use single-use, sterile needles and follow strict clinical protocols. Serious complications are extremely rare.
