Dry Needling
Dry needling involves inserting thin, solid filiform needles (the same type used in acupuncture) directly into muscles, tendons, ligaments, or near nerves, without injecting any substance, hence the term "dry." The goal is to target specific points of dysfunction, most commonly myofascial trigger points (tight, irritable knots within muscle tissue).
The therapist identifies the trigger point through palpation (feeling the muscle). The needle is then inserted and may be moved gently up and down to elicit the local twitch response. Patients often feel a dull ache, pressure, or a brief muscle cramp during the twitch, which, while momentarily uncomfortable, is typically a sign the treatment is working.
During treatment
Mild soreness for 24–48 hours afterward is normal and similar to post-exercise soreness. This is followed by a noticeable reduction in tightness and pain. Dry needling is rarely used in isolation. It's typically combined with stretching, strengthening exercises, and manual therapy for best results.
After treatment
Though they use the same needles, the two are philosophically different. Acupuncture is rooted in traditional Chinese medicine and targets energy pathways called meridians. Dry needling is grounded in Western anatomy and neuroscience, targeting specific muscular and neurological structures.
Dry needling works by mechanically and neurologically disrupting dysfunctional muscle tissue, triggering the body's natural healing response and restoring normal muscle function and pain-free movement.
Dry needling vs. acupuncture
Conditions that benefit:
-
Dry needling is a technique used by physical therapists that involves inserting a thin, sterile needle into tight, knotted muscles to release tension and reduce pain. By stimulating these trigger points, it improves blood flow and supports the body's natural healing process. When combined with a personalized physical therapy program, dry needling can be an effective solution for chronic pain, muscle tightness, and sports injuries.
-
Dry needling can be a highly effective treatment for those suffering from chronic headaches and migraines. Many headaches stem from tight, knotted muscles in the neck, shoulders, and upper back that refer pain into the head. By targeting these trigger points with a thin, sterile needle, physical therapists can release muscle tension, improve circulation, and reduce the nerve irritation that contributes to headache symptoms.
-
Dry needling helps with shoulder impingement by targeting tight trigger points in the rotator cuff muscles, such as the supraspinatus and trapezius, using thin needles to release muscle tension and reduce compression within the subacromial space. This release improves shoulder mobility, decreases pain, and enhances blood flow to the area, making it a valuable complement to strengthening and manual therapy in a comprehensive rehab program.

When a needle is inserted into a trigger point, several physiological responses occur:
Local twitch response — The muscle involuntarily contracts and then relaxes, which is considered a sign that the correct spot has been targeted. This twitch helps release the tight band of muscle fibers.
Increased blood flow — The needle creates a minor controlled injury that draws circulation to the area, delivering oxygen and nutrients while flushing out metabolic waste products that accumulate in tight muscles.
Neurological reset — The needle stimulates the nervous system, disrupting pain signals and helping to normalize the way the brain communicates with that muscle.
Chemical change — Trigger points are known to have elevated levels of inflammatory chemicals (like substance P and bradykinin). Needling helps reduce these, lowering pain sensitivity in the area.
