Application of Repetitive Transcranial Magnetic Stimulation for the Treatment of Restless Legs Syndrome: A Pilot Study

Abstract

ObjectiveTo explore effects of high frequency repetitive transcranial magnetic stimulation (rTMS) on restless legs syndrome (RLS) patients. Methods18 primary RLS patients were divided into rTMS group and sham stimulation group. rTMS treatment group received 15 Hz high-frequency rTMS to stimulate the leg motor representative area of the frontal cortex for 14 days and the sham stimulation group received 15 Hz high-frequency rTMS sham stimulation in primary motor cortex for 14 days. ResultsAfter rTMS, RLS severity scale score, Pittsburgh sleep quality index (PSQI), Hamilton anxiety scale (HAMA) as well as Hamilton depression scale (HAMD24) in rTMS treatment group are significantly lower than before treatment; 1 month and 2 months after treatment, the score remained at low level. Meanwhile, no significant changes have been observed in the above index before rTMS stimulation for the sham stimulation group after 14 days, after 1 month and 2 months. In addition, the results of correlation analysis suggested for all the 18 RLS patients, there was a positive correlation between PSQI score and HAMA as well as HAMD24 scores before and after rTMS stimulation. In addition, the RLS severity score was also positively correlated with PSQI, HAMA and HAMD24 scores. ConclusionsHigh frequency rTMS stimulation reduces the frequency and severity of RLS, improves the quality of sleep, anxiety as well as depression of the patients, and the curative effect can sustain for 2 months. High-frequency rTMS may be used as an alternative treatment option for improving the RLS patients’ quality of life.
