Objectives: The purpose of this study is to provide anatomical information, as well as applicable needling methods and related physiological effects of GB30. Methods: Through the literature analysis, the location, needling method, clinical effect of GB30 were extracted. Based on this information, we investigated the stimulable structures and their therapeutic effects related with GB30 from literature. Results: Connecting the anatomical structures that can be stimulated by needling at GB30 with the clinical effects of GB30, the following can be observed: the inferior gluteal nerve and gluteus maximus, sciatic nerve, piriformis muscle, and gemelli-obturator complex, were associated with symptoms in the waist and lower extremity regions. The quadratus femoris muscle, pudendal nerve, and posterior femoral cutaneous nerve were related to sacroiliac pain. Conclusion: This study has provided insights into the depth and direction of needling at GB30, along with the anatomical structures that can be stimulated as a result, and their corresponding therapeutic effects.
