How is dry needling classified in terms of invasiveness?

Dry needling is classified as an invasive technique because it involves the insertion of a thin needle into the skin and underlying tissues to target trigger points or muscle knots. This procedure penetrates the skin barrier, which inherently characterizes it as invasive. The technique is designed to elicit a local physiological response, promoting healing and reducing muscle tension.

It’s important to highlight that while dry needling is generally safe when performed by a trained practitioner, the act of inserting needles does pose a degree of risk, such as potential infection, bleeding, or other complications. This differentiates it from non-invasive techniques, which do not involve such penetration of the skin, and semi-invasive techniques, which might involve techniques like injections that disrupt tissue to a lesser extent than needle insertion. Furthermore, designating it as a "pain-free method" may misrepresent the process; patients may experience discomfort or a sensation during the insertion of needles, although skilled practitioners often work to minimize pain.
