Study tests whether blind dry needling actually targets the correct muscles in tennis elbow

This study looks at whether blind dry needling (inserting thin needles into muscles without imaging guidance) accurately targets the forearm extensor muscles in people with tennis elbow. Researchers will use ultrasound to see if the needle ends up in the intended muscle. The study involves 40 adults aged 18-70 who have had lateral elbow pain for at least 6 weeks and have active trigger points. The goal is to measure how often the needle hits the correct muscle, not to test if it reduces pain.
