From: Transcutaneous electrical stimulation at auricular acupoints innervated by auricular branch of vagus nerve pairing tone for tinnitus: study protocol for a randomized controlled clinical trial

Figure 2

Locations and stimulation devices. (A) Points used in the ABVN group and the ABVN plus tone group for transcutaneous electrical nerve stimulation. (B) Points used in the non-ABVN plus tone group for transcutaneous electrical nerve stimulation. (C) Acupoints used in the electrical acupuncture group. (D) Locations of acupoints in the acupuncture group. local acupoints: Tinghui (GB2) and Yifeng (TF17); distal acupoints: Zhongzhu (TE3) and Xiaxi (GB43). (E) Innervation of the human auricle, including ABVN (blue grid), great auricular nerve (green grid) and auriculotemporal nerve (red grid) [17]; the black areas show the specific auricular acupoints. TF4, CO10-12, and HX1 are used in the ABVN group and the ABVN plus tone group; HX9 and LO5 are used in the non-ABVN plus tone group. (F) Ideograph of sound (tones) stimulus: each speakers is equidistant from the head of the subject.
