The search timeframe was from the inception of each database to October 2023. Literature was screened according to inclusion and exclusion criteria. Two researchers extracted information on study subjects, age, intervention methods, intervention duration, intervention frequency, evaluation indicators, and intervention results from the included literature. The modified Jadad scale was used to evaluate the quality of the literature.ResultsA total of seven studies were included, mainly focusing on the frequency, duration, and stimulation site of rTMS for dysarthria in PD patients. Six studies indicated that rTMS treatment improved dysarthria in PD patients.ConclusionRepetitive transcranial magnetic stimulation has a positive effect on improving dysarthria in PD patients, but further research is needed to determine its efficacy.
