This study examined the effect of both the BrainsWay® Deep TMS (Transcranial Magnetic Stimulation) H-coil and circular-coil stimulation on patients suffering from abnormal blinking or spasms of the eyelids. In the study, patients underwent a 15-minute session of repetitive transcranial magnetic stimulation over the ACC. In this study it was demonstrated that although both type of coils were effective compare to a sham coil, and significantly alleviate symptoms, acute brain stimulation using the H-coil required a significantly lower stimulation intensity.
