NCT02290015

Brief Summary

This trial was a randomized, single-blinded, sham-controlled study, in which the patients were blinded to treatment assignment. First, all candidates underwent audiological testing of hearing thresholds, tympanometry and stapedius reflex tests. The patients who were selected for the study were interviewed to assess and evaluate their condition and then underwent a detailed physical examination that included a complete otorhinolaryngologic examination and a complete blood test. Then, the subjects were randomized to undergo true or sham ACP. Seven days before (baseline) and seven days after twelve acupuncture (ACP) sessions (up to six weeks), which were performed twice a week, all participants underwent 99mTc-ECD SPECT scanning and completed the Portuguese version of the Tinnitus Handicap Inventory (THI), the Visual Analogue Scale (VAS), Hamilton Anxiety Scale (HAS) and the Beck Depression Inventory (BDI). The purpose of this study was to integrate the neuroscience research findings with the clinical research on tinnitus. Thus, a randomized, single-blinded, placebo-controlled trial was implemented to investigate the effect of ACP as a treatment for tinnitus using ethylcysteine dimer single-photon emission computer tomography (99mTc-ECD SPECT).

EXPERIMENTAL

12 sessions of ACP treatment were performed twice a week. Before ACP was performed, patients were examined based on the diagnostic pattern of TCM. Then, the appropriate acupoints for treatment were selected according to the tinnitus-related syndrome. The experimental group was treated with true ACP (stimulating selected meridian points), and the control group was treated with sham-ACP (stimulating false meridian points). The patients were blinded to the identity of their treatment group. Disposable stainless steel ACP needles (0.25 x 30 mm, Dong Bang Acupuncture, Korea) were used in both groups. Needles were inserted manually at each meridian point, and the retention time was twenty minutes.

SHAM COMPARATOR

The control group was treated with sham-ACP (stimulating false meridian points). Disposable stainless steel ACP needles (0.25 x 30 mm, Dong Bang Acupuncture, Korea) were used. Needles were inserted manually at each false meridian point, and the retention time was twenty minutes.

Other: Acupuncture

Interventions

All treatments were performed by the same acupuncturist, who is a medical doctor with more than eight years of clinical and research experience in ACP for tinnitus. Acupoints described as being effective for tinnitus were selected according to TCM theory. Basic points that are manipulated in ACP include GV 20 (Baihui), TE 17 (Yifeng), GB 8 (Shuaigu), SI 19 (Tinggong), GB 2 (Tinghui), TE 21 (Ermen), VC 23 (Lianquan), GB 20 (Fengchi), TE 2 (Yemen), TE 5 (Waiguan), SI 2 (Qiangu), GB 43 (Xiaxi) and GB 41 (Zulinqi). However, several secondary (accessory) acupoints were also added according to TCM and the etiological diagnosis of tinnitus: GV 4 (Mingmen), KI 3 (Taixi), BL 23 (Shenshu), BL 19 (Danshu), BL 18 (Ganshu) and CV 4 (Guanyuan).
