Both treatments use the same thin filiform needles. Both can relieve pain. So patients are often confused — or assume they're the same thing. They're not. Dry needling and acupuncture differ fundamentally in their underlying theory, target tissue, practitioner training, and clinical application. Here's a clear breakdown.
The Core Difference in One Sentence
Acupuncture is rooted in Traditional Chinese Medicine (TCM) and works by stimulating specific points along energy pathways called meridians to restore the flow of qi (life energy). Dry needling is based on Western anatomy and neurophysiology, targeting myofascial trigger points — tight, irritable knots in muscle tissue — to restore normal muscle function and reduce pain.
Side-by-Side Comparison
| Feature | Dry Needling | Acupuncture |
|---|---|---|
| Theoretical basis | Western anatomy & neuroscience | Traditional Chinese Medicine (TCM) |
| Target | Myofascial trigger points | Meridian acupoints |
| Goal | Release tight muscle knots, reduce pain | Restore qi flow, balance energy |
| Practitioner | Physical therapist (post-grad certified) | Licensed acupuncturist (LAc) |
| Training required | DPT + certification course (40–80 hrs) | Master's/Doctorate in Oriental Medicine (3–4 yrs) |
| Needle placement | Directly into painful muscle tissue | Along traditional meridian pathways |
| Needle depth | Varies by muscle depth (often deeper) | Typically superficial to moderate depth |
| Twitch response sought? | Yes — key therapeutic indicator | No — not a primary goal |
| Used alongside PT exercise? | Yes — integrated into PT plan | Typically standalone treatment |
| Insurance coverage | Sometimes covered (as PT modality) | Rarely covered |
| Evidence base | Strong for musculoskeletal pain | Mixed; stronger for headaches, nausea |
What Is Dry Needling — In Detail?
Trigger point dry needling (TDN) targets myofascial trigger points: hyperirritable spots within a taut band of skeletal muscle. These knots can cause local pain, referred pain patterns, reduced range of motion, and muscle weakness.
When a thin needle is inserted directly into a trigger point, several things happen:
- Local twitch response (LTR): The muscle involuntarily contracts and releases — like a reset button. This is the hallmark of effective needle placement.
- Neurochemical changes: The LTR alters the local chemical environment, reducing the concentration of pain-sensitizing substances like substance P and bradykinin.
- Improved blood flow: The needle disrupts the ischemic (low-oxygen) environment of the trigger point, restoring circulation.
- Descending pain inhibition: The stimulus activates central pain modulation pathways, producing systemic analgesic effects beyond the needle site.
Conditions Dry Needling Treats Most Effectively
At EverStrong Physical Therapy, dry needling is most commonly used for:
- Chronic low back pain with myofascial involvement
- Neck pain and cervicogenic headaches
- Shoulder pain (rotator cuff, frozen shoulder)
- Plantar fasciitis (intrinsic foot muscles)
- Tennis elbow / golfer's elbow (lateral/medial epicondylalgia)
- Hip flexor tightness and hip pain
- IT band syndrome
- Post-surgical scar tissue management
- Fibromyalgia (as part of a multimodal approach)
What Is Acupuncture — In Detail?
Acupuncture is a component of Traditional Chinese Medicine practiced for over 2,500 years. TCM theory holds that vital energy (qi) flows through 14 main meridians in the body. Disease and pain occur when this flow is blocked. Inserting needles at specific acupoints along the meridians restores flow and promotes healing.
From a modern neuroscience perspective, acupuncture likely works through:
- Local microcirculation changes at the needle site
- Activation of the autonomic nervous system
- Release of endorphins and other neuropeptides
- Modulation of the hypothalamic-pituitary axis
Acupuncture has the strongest evidence base for: chronic headaches/migraines, chemotherapy-induced nausea, chronic low back pain, osteoarthritis of the knee, and some post-surgical pain reduction.
Which Is Right for You?
The choice between dry needling and acupuncture depends on what you're treating and your personal preferences:
| Your Situation | Consider |
|---|---|
| Tight, painful muscle knots (trigger points) | Dry Needling |
| Post-surgical recovery, sports rehab | Dry Needling (as part of PT) |
| Chronic migraine or tension headaches | Either (both have evidence) |
| Neck/back pain with referred symptoms | Dry Needling |
| Chemotherapy nausea, fertility support | Acupuncture |
| Prefer a holistic/TCM approach | Acupuncture |
| Want treatment integrated with PT exercise | Dry Needling at EverStrong |
| Insurance covers PT | Dry Needling (billed through PT) |
Safety and Side Effects
Both treatments are very safe when performed by trained practitioners. For dry needling specifically:
- Common: Muscle soreness 24–48 hours post-treatment (similar to a deep tissue massage or workout)
- Occasional: Minor bruising at needle sites
- Rare: Temporary dizziness or lightheadedness (usually position-related)
- Very rare: Pneumothorax (lung puncture) — only when needling near the thorax without proper training and technique
At EverStrong, all dry needling is performed by licensed DPTs with post-graduate certification. We use single-use, sterile needles — no exceptions.
Dry Needling by PTs in Tennessee
Tennessee physical therapists are permitted to perform trigger point dry needling within their scope of practice. This has been the case since the Tennessee Physical Therapy Practice Act was interpreted to include dry needling as an appropriate PT modality — provided the PT has completed an accredited post-graduate dry needling course.
Our therapists at EverStrong hold their dry needling certifications and have extensive hands-on experience. If you have questions about whether dry needling is appropriate for your condition, your first visit evaluation will include a thorough discussion of all treatment options.

Frequently Asked Questions
No. While both use thin filiform needles, dry needling and acupuncture are based on completely different theories, target different structures, and have different goals. Dry needling targets myofascial trigger points using Western anatomical and neurophysiological principles. Acupuncture is based on Traditional Chinese Medicine concepts of qi and meridians.
Most patients feel a brief twitch response when the needle contacts a trigger point — often described as a momentary cramp or deep ache. This sensation typically lasts less than a second and is actually a sign that the right tissue has been targeted. Post-treatment muscle soreness (similar to a workout) can last 24–48 hours but typically resolves on its own.
Yes. Licensed physical therapists in Tennessee are permitted to perform trigger point dry needling as part of their scope of practice, provided they have completed an approved post-graduate dry needling certification course. At EverStrong, our therapists are certified and have performed dry needling as part of comprehensive PT plans for years.
