Dry Needling

Rita Chiaramonte et al. (2026) · The Journal of manual & manipulative therapy

This systematic review of 18 randomized controlled trials explored whether hands-on treatment eases pain and improves jaw movement in adults with temporomandibular disorders (TMD). TMD is a group of conditions affecting the jaw joint, the chewing muscles and nearby tissues, and it is estimated to affect about 31% of adults. Its subtypes include muscle pain (myalgia), disc displacement (the cushioning disc slips out of position, sometimes locking the jaw) and joint pain. Manual therapy covers thrust manipulation, soft-tissue release, massage and intra-oral techniques, delivered by physiotherapists, chiropractors, osteopaths, dentists and physicians. The review asked which techniques help most and whether results differ by profession. Researchers searched four databases through March 2025 and screened 561 records, keeping 18 trials of adults with a clinical TMD diagnosis. Trials compared manual therapy with sham treatment, no treatment, splints, medication, exercise or education. Pain was rated on the visual analogue or numeric rating scale (0 to 10), and maximum mouth opening was measured in millimetres. Risk of bias was checked with the Cochrane tool and certainty with GRADE. Because the trials differed so widely in technique, dose, comparator and follow-up, results were summarized in words rather than pooled statistically. Most trials reported short-term pain reduction and wider mouth opening, but certainty was low to moderate for pain and low for mouth opening. High-velocity low-amplitude (HVLA) thrusts made up 56% of interventions and fascial manipulation with myofascial release made up 37.5%. Dry needling plus upper neck HVLA beat splint therapy, diclofenac and joint mobilization at three months (p < 0.001), and intra-oral therapy kept benefits for one year in chronic jaw-muscle pain. Upper thoracic HVLA showed no significant effect (p > 0.05), and jog manipulation gained only 6.86 mm of mouth opening at first visit with no later group difference. Massage and fascial manipulation by physiotherapists were linked to relief of jaw-muscle symptoms, while chiropractic, osteopathic and dental trials also reported gains. Physiotherapy trials were the most numerous, which the authors attribute to publication volume rather than superior effectiveness. The authors describe manual therapy as associated with short-term benefit and treat professional comparisons as descriptive, since profession was tangled with setting, technique and country. Limitations include small samples, short follow-up, mixed diagnoses, English-only searching and no meta-analysis. Safety findings were not reported in pooled form, and the evidence mostly covers weeks to months rather than years. The authors call for larger trials with longer follow-up and standardized protocols, and they state that manual therapy is best delivered by trained, licensed professionals.

He Chen et al. (2024) · Current pain and headache reports

Does acupuncture keep helping knee osteoarthritis after the needles stop? A 2024 systematic review and meta-analysis in Current Pain and Headache Reports pooled 10 randomized controlled trials with 3,221 participants to answer exactly that, and found benefits lasting roughly 3 to 6 months after the final session. The durability depended on the comparison. Against sham acupuncture, real acupuncture kept function measurably better for 4.5 months after treatment ended, and overall pain stayed lower through 4.5 months as well. Against usual care, both pain relief and functional improvement remained large enough to matter clinically for 5 months. One trial comparing dry needling with the anti-inflammatory drug diclofenac found relief persisting 6 months after treatment ended. Not every comparison favored acupuncture. When it was added on top of exercise-based physical therapy, it added nothing measurable for up to 11 months — exercise appears to occupy much of the same therapeutic ground. And two no-treatment-controlled trials disagreed, one showing 3 months of persistence and the other showing benefits only at end of treatment. Safety was consistently good across trials, with no significant excess of adverse events. For the estimated one in five adults over 40 living with knee osteoarthritis, the practical takeaway is that a 4-to-12-week course of acupuncture (typically 1–3 sessions weekly) can deliver relief that outlasts treatment by months — something NSAIDs and steroid injections generally cannot claim. It works best as its own treatment or alongside routine care, not stacked on structured exercise therapy, and results should be weighed knowing each individual comparison rested on relatively few trials.
