Which of the following states has NOT approved dry needling for physical therapy practice?

California has not approved dry needling for physical therapy practice, which is the reason this choice is correct. This reflects the state's regulatory environment and the ongoing discussions regarding the safety and effectiveness of dry needling as a treatment modality. While many states have accepted dry needling as part of physical therapy practice, California's stance indicates that practitioners there may need to pursue alternative methods or approaches that are compliant with state regulations.

In contrast, states like Texas, Tennessee, and Illinois have recognized dry needling as an acceptable practice under the scope of physical therapy. This approval usually follows guidelines set forth by state boards and physical therapy associations, which assess the training requirements and the practice's clinical relevance. Understanding the nuances of each state's regulations is crucial for practitioners operating across state lines in order to remain compliant with legal and professional standards.
