The aim of the study was to compare the effects of two techniques of repetitive Transcranial Magnetic Stimulation (rTMS) to treat chronic tinnitus; continuous Theta Burst Stimulation (cTBS) and high-frequency rTMS. In a controlled randomized clinical trial, 55 patients with chronic tinnitus were randomly divided in two groups. They received four sessions of treatment. cTBS was tested on one group and high-frequency rTMS (10 Hz) was tested on the other. Severity of the tinnitus was assessed before treatment, after the last treatment session and then 1-month later. Both the treatments of high-frequency and cTBS had a suppressive effect on tinnitus. However, cTBS was more effective than high-frequency rTMS (P = 0.001). This study suggests that rTMS even in four sessions is effective in reducing tinnitus severity; moreover, compared to high-frequency TMS better results can be achieved with cTBS.
本研究旨在比较两种经颅重复磁刺激(rTMS)技术治疗慢性耳鸣的效果；连续 theta 爆发刺激(cTBS)和高频 rTMS。在一项对照随机临床试验中，将 55 例慢性耳鸣患者随机分为两组。他们接受了四次治疗。一组接受 cTBS 治疗，另一组接受高频 rTMS（10Hz）治疗。在治疗前、最后一次治疗后和 1 个月后评估耳鸣的严重程度。高频和 cTBS 治疗均对耳鸣有抑制作用。然而，cTBS 的效果优于高频 rTMS（P=0.001）。本研究表明，即使进行四次 rTMS 治疗，也能有效降低耳鸣严重程度；此外，与高频 TMS 相比，cTBS 可获得更好的效果。
