Abstract
Background: Past research highlighted the benefits of personalized repetitive transcranial magnetic stimulation (rTMS) for the treatment of chronic subjective tinnitus.Objective/Hypothesis: The objective was to investigate the feasibility of rTMS personalization by identifying individually optimal stimulation parameters in test sessions. Particularly, effectiveness and retest–reliability of different stimulation parameters were examined.Methods: Via electric-field guided rTMS, five patients were stimulated with different frequencies on three positions of the left and right superior temporal gyrus on 2 separate days. After each stimulation, the patients had to evaluate tinnitus loudness and discomfort of the used protocol.Results: Individualization of rTMS was possible in all five patients. Significant lower tinnitus loudness was found for 1 Hz stimulation. Positive correlations between 2 days were observed for hemisphere (left, right), position (mSTG, pSTG), and frequency (1, 10, 20 Hz). High-frequency stimulation produced high discomfort.Conclusion: Personalization of rTMS is considered as feasible. Consistency of parameter-specific tinnitus suppression is demonstrated.
Highlights
Current research findings in the field of neurostimulation and tinnitus are still ambiguous with respect to the effectiveness of repetitive transcranial magnetic stimulation for the treatment of chronic subjective tinnitus [1]
Tests for loudness rating reliability discovered a positive correlation between day 1 and day 2 for the left and right hemispheres and for the stimulation positions mSTG and pSTG
The aim of this study was to examine if a personalization of repetitive transcranial magnetic stimulation (rTMS) with e-field guided neuronavigation is feasible and reliable
Summary
Current research findings in the field of neurostimulation and tinnitus are still ambiguous with respect to the effectiveness of repetitive transcranial magnetic stimulation (rTMS) for the treatment of chronic subjective tinnitus [1]. It remains unclear which stimulation parameters, e.g., stimulation positions or frequencies, are most effective. To combat this uncertainty and to enhance the potential efficacy of rTMS for tinnitus, two promising approaches are provided by the personalization of rTMS treatments. Past research highlighted the benefits of personalized repetitive transcranial magnetic stimulation (rTMS) for the treatment of chronic subjective tinnitus
