Lack of efficacy of theta-burst stimulation in chronic tinnitus

Objective: Modulation of cortical excitability by means of transcranial stimulation has developed as a research focus in neurophysiology and as a treatment option in neuropsychiatry. In chronic tinnitus it is thought that cortical excitability changes as well as imbalances of excitatory and inhibitory influences play a distinct pathophysiological role. Repetitive transcranial magnetic stimulation (rTMS) over the auditory cortex was recently introduced to modulate tinnitus perception. The aim of the current study was to investigate the effect of theta burst stimulation (TBS), a novel rTMS paradigm, on chronic tin…
