By studying articles related to rTMS, I realized that different frequencies have been used for stimulation to treat tinnitus, with the use of 1Hz being the most common.
So, the question arose for me on what basis the frequency of rTMS is selected.
For the selection of frequency in case of rTMS for tinnitus it is necessary to stimulate the relevant cortex. If less frequency is selected it would not stimulate the specific cortex eg. Temporal lobe as because the relative thickness of the temporal bone is stimulated by frequency around 1Hz.
And if we set a higher frequency it would overstimulate the cortex. That will produce more tinnitus.
So traditionally 1Hz is used with a variable result. But research may be take place to reduce the variability in outcome whether this explanation is correct or not.
