Effective and Safety Analysis of Electroacupuncture Treatment for Restless Legs Syndrome in Maintenance Hemodialysis Patients

Abstract

BACKGROUND: Restless legs syndrome (RLS) is a common complication in maintenance hemodialysis (MHD) patients. Current study was conducted to analysis the effectiveness and safety of electroacupuncture on 3 acupuncture points from lower limb meridians in the treatment of RLS. METHODS: A total of 7 MHD patients (5 Male and 2 Female) in our center with severe RLS symptom were enrolled. After one month of pharmacological washout period, patients received 12 sessions of electroacupuncture on three acupoints (Zusanli (ST36), Sanyinjiao (SP6) and Taichong (LR-3)) during HD. Severity of RLS symptoms and the sleep quality were evaluated by IRLSSG and ISI scores for 3 times (before, after and 1 month later of the electroacupuncture treatment). RESULTS: The average age of enrolled patients was 52.6±8.9 years, with median dialysis duration of 3.0 years. The hemoglobin level was 125.9±22.9 g/l. The IRLSSG score was significantly lower after electroacupuncture treatment (9.4±3.9) than that before treatment (17.3±4.7) (P <0.01). Both overall severity of RLS symptom average daily severity and frequency were significantly improved after electroacupuncture. It is also validated that the electroacupuncture treatment was contributed to sleep improvement in RLS patients after electroacupuncture treatment was discontinued for one month. CONCLUSION: Electroacupuncture on three lower limbs acupoints during MHD was as a safe and effective treatment for attenuating the symptoms of RLS and improvement of sleep quality in hemodialysis patients, and the therapeutic effect maintain for at least one month.
