    Repetitive Transcranial Magnetic Stimulation Does Not Improve the Sequence Effect in Freezing of Gait by Jinghong Ma, Linlin Gao, Taomian Mi, Junyan Sun, Piu Chan, Tao Wu

    Published 2019-01-01
    “…Real rTMS had beneficial effects on FOG and some gait parameters, and this effect lasted for at least four weeks. Conclusions. High-frequency rTMS over the SMA cannot alleviate the SE in PD patients with FOG. rTMS has a long-lasting beneficial effect on FOG; however, this effect is not achieved by improving the SE but may be through improving some other gait parameters.…”
