Effects of Repetitive Transcranial Magnetic Stimulation on Auditory Processing in Tinnitus Patients

Objective To investigate the effects of repetitive transcranial magnetic stimulation(rTMS)with different stimulation frequencies on auditory processing function in patients with subjective tinnitus.Methods Ten patients with subjective tinnitus were randomly divided into low frequency group and high frequency group.The low frequency group received 1Hz stimulation frequency,and the high frequency group received 10Hz stimulation frequency,once a day,5 days a week,for 2 consecutive weeks.All the patients underwent tinnitus assessment,speech test under noise,gap in noise(GIN)detection and dichotic digits test before treatment,at 5 and 10 days after treatment respectively.Results In the low-frequency group,the THI score,GIN threshold,speech recognition rate under white noise,and speech recognition rate under Babble were significantly different after 5 days of rTMS treatment,THI score,VAS score,GIN threshold,speech recognition rate under white noise,and speech recognition rate under Babble were significantly different from pre-treatment after 10 days of rTMS treatment.In the high-frequency group,there were significant differences in THI score and speech recognition rate under white noise after 5 days of rTMS treatment compared with before treatment,and significant differences in THI score,VAS score,GIN threshold and speech recognition rate under white noise after 10 days of treatment.Compared with the same time point between the two groups,only after 10 days of treatment,the speech recognition rate of the low-frequency Babble group was significantly higher than that of the high-frequency group.Conclusion rTMS treatment at the two stimulation frequencies could improve auditory processing in patients with subjective tinnitus to some extent.
