Real Dry Needling and Placebo Dry Needling Applied With and Without Ultrasound Guidance on the Infraspinatus Muscle

The dry needling technique involves inserting a sterile needle to stimulate a myofascial trigger point with the aim of reducing pain and increasing range of motion and quality of life. This technique can be performed using ultrasound guidance, which allows us to visualize the needle at all times, but it can also be done using anatomical landmarks. In the placebo dry needling technique, the needle will remain stationary in the subcutaneous tissue.
