Evaluation of the Effectiveness of Dry Needling Treatment in Patients Diagnosed with Greater Trochanteric Pain Syndrome

Greater Trochanteric Pain Syndrome (GTPS) is characterized by lateral hip pain, pain radiating to the lateral leg, tenderness and rotation around the greater trochanter, and pain with specific activities such as abduction or adduction. GTPS is primarily diagnosed clinically. Conservative treatment for GTPS includes activity modification, physiotherapy, nonsteroidal anti-inflammatory drugs, local corticosteroids, and platelet-rich plasma injections. Particularly, regional muscle sensitivity, such as in the gluteus maximus, is prominent. In recent years, dry needling therapy, which has gained popularity and increased research attention, has become an alternative treatment option, especially if the underlying cause is myofascial pain syndrome or deeper issues like piriformis syndrome.

The provided text discusses dry needling as a treatment for various neuromusculoskeletal pain conditions, emphasizing its use as a minimally invasive procedure that involves applying filiform needles to the relevant muscle tissue without the administration of pharmacological drugs. The literature suggests that dry needling therapy has the ability to induce biochemical, biomechanical, endocrinological, and neurovascular changes associated with the reduction of pain and disability in individuals. However, the optimal treatment dosage has not yet been determined, and there is inconsistency in the literature regarding the number of needles to be inserted and the duration of needle retention.

Studies evaluating the effectiveness of dry needling are often designed to compare or add it to other injection therapies. Additionally, there is a limited number of studies conducted with real-time imaging. In the planned study, the use of ultrasound-guided dry needling aims to provide a sham application opportunity, where the patient is blinded to the nature of the procedure, allowing for a meaningful investigation of efficacy. This aspect of the study is expected to contribute significantly to the literature.
