An intervention program was conducted with two groups of patients who had experienced stroke: one which
received low-frequency rTMS and occupational therapy (rTMS-OT Group), and one which received occupational
therapy only (OT group). The treatment was provided three times per week for 4 weeks followed by a 1-
week evaluation of MEP amplitude and latency, and muscle tone. In an intergroup test of MEP amplitude and
latency, and muscle tone, all groups showed increases between pre-and post-test evaluations. As a result of the
study, during the treatment intervention of the experimental group and the control group, the experimental
group rTMS-OTG and the control OTG group showed MEP amplitudes of 0.161 mV and 0.114 mV, respectively,
and the experimental group showed more improvement. The MEP latency of the rTMS-OTG group was
-2.83 ms and the MEP latency of the OTG group was -1.49 ms. The experimental group, rTMS-OTG,
responded faster. However, in the case of muscle tone evaluation, there was no significant difference between
the two groups. In conclusion, we determined that rTMS may be safely applied to the directly damaged cerebral
cortex and is considered to be an effective treatment for patients recovering from stroke.
