Design of dry-needling and acupuncture sham devices: an illustrative review.
Yiu Ming Wong
PMID 41036528WHAT IT FOUND
Five sham needle devices were identified that look and feel like real acupuncture but do not penetrate the skin.
Only one allows the therapist to be blinded too, which is critical for rigorous trials. No standard device exists yet.
Key findings
01Five validated sham needle devices were identified, all designed to be non-penetrating while mimicking the sensation of real needling.
02The Takakura device is the only one specifically designed to allow double-blind masking, meaning both the patient and the clinician are unaware of the treatment allocation.
03There is currently no standardized sham device, and research has not determined which of the five is optimal for different body regions or outcomes.

What it does not show
This is a narrative review of device designs, not a clinical trial, so it does not provide evidence on the efficacy of dry needling itself. The review notes that even the validated sham devices may not be perfect inert placebos, as they can still cause a weak neurological response compared to real needling. There is no data on which device is best for specific body regions, limiting direct application for trial design in specific anatomical areas.
Declared interests
The author has no conflicts of interest to declare.
The easy way to misread this
Do not interpret this review as evidence that dry needling works or does not work. It only describes the tools researchers use to test it. The lack of a standardized sham device means that results from different dry needling trials may not be directly comparable.
