Which of the following is a contraindication for dry needling?

Blood clotting disorders are considered a contraindication for dry needling because they increase the risk of bleeding or hematoma formation at the needle insertion site. In individuals with such disorders, the body's ability to form clots is compromised, which can lead to serious complications if the skin or underlying tissues are punctured during the procedure. Practitioners must carefully assess a patient's medical history for any conditions that could affect hemostasis before proceeding with dry needling.

In contrast, increased muscle flexibility, regular exercise, and chronic pain conditions are not contraindications; in fact, they might be indicators for the use of dry needling as part of a comprehensive treatment approach to enhance muscle function or manage pain.
