  • Effectiveness of High- and Low-frequency Repetitive Transcranial Magnetic Stimulation for Treating Dysfunction in Patients with Parkinson’s Disease: A Meta-analysis

    Objective To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) for treating dysfunction in patients with Parkinson’s disease (PD). Methods We searched the Cochrane Library (Issue 1, 2010), MEDLINE, EMbase, CBMdisc, and CNKI from the date of the database establishment to April 2010. Randomized controlled trials (RCTs) of rTMS for patients with PD were collected. The quality of the included RCTs was critically appraised and data were extracted by two reviewers independently. Meta-analyses were conducted for the eligible RCTs. Results Eight RCTs were included. The pooled results of the first 2 RCTs showed that, there was no significant difference compared with control group about treating PD patients with clinical motor dysfunction by high-frequency rTMS 10 days later (WMD= –4.75, 95%CI –13.73 to 4.23). The pooled analysis of another 3 studies showed that, no significant difference were found about improving symptoms with treatment of low-frequency rTMS for 1 month compared with control group (WDM= –8.51, 95%CI –18.48 to 1.46). The pooled analysis of last 3 studies showed that, patient with treatment of low-frequency rTMS for 3 months, had been significantly improved in clinical symptoms such as neurological, behavior and emotional state, clinical motor function, and activities of daily living (WDM= –5.79, 95%CI –8.44 to –1.13). The frontal or motor cortex rTMS manifested as low frequency (≤1Hz), high intensity (≥90% RMT), multi-frequency (≥3 times) and long time (≥3 months) had a positive effect on the clinical symptoms of patients with PD and also had a long-term effect. Conclusions rTMS can improve clinical symptoms and dysfunction of the patients with PD.

  • Low Frequency Repetitive Transcranial Magnetic Stimulation (rTMS) for Major Depressive Disorder: A Systematic Review

    Objective To systematically review the efficacy of low-frequency repetitive transcranial magnetic stimulation (rTMS) compared with sham therapy for the treatment of major depressive disorder. Methods The Cochrane Library, Medline, EMbase, CBMdisk, CNKI and VIP were searched through computer from 1985 to 2011. The review included RCTs comparing the treatment efficacy of low-frequency rTMS located on right dorsolateral prefrontal cortex (DLPFC) with sham stimulation in the patients suffering major depressive disorder. The quality of the included RCTs was strictly evaluated and the data were extracted by two reviewers independently. The extracted data were analyzed by RevMan 4.2. Results Among seven double-blinded RCTs involving 234 patients included, 1 was A level in quality, 5 were B level, and 1 was C level according to the outcomes of quality evaluation. The results of Meta-analysis indicated that low frequency rTMS was superior to sham stimulation in remission rates after two weeks’ treatment (RR=3.11, 95%CI 1.56 to 6.19). Additionally, low frequency rTMS was lower than the sham stimulation in the scores of HDRS and MADRS (WMD= –6.41, 95%CI –9.32 to –3.50, and WMD= –5.27, 95%CI –9.08 to –1.46, respectively). But no significant difference in response rates between the low prequency rTMS group and the sham group was found (RR=1.72, 95%CI 0.74 to 4.01). There were no severe and intolerable side effects reported in these seven studies. Conclusion The low frequency rTMS as a non-invasive and safe technique may appear to be effective for the treatment of major depressive disorder according to the positive results but the conclusion is not definite because of negative results. This review suggests that parameters could be sited as frequency: 1 Hz, intensity: 90%-110% motor threshold (MT), location: right DLPFC and duration: 2 weeks. Nevertheless, further multicenter and high quality studies are needed before it is used as a first-line treatment for major depressive disorder.

  • Effectiveness of Repetitive Transcranial Magnetic Stimulation in Stroke Patients with Motor Dysfunction: A Systematic Review

    Objective To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in treating stroke patients with motor dysfunction. Methods The Cochrane Library, MEDLINE, EMbase, CBM, CNKI and WanFang Data were searched from inception to January 2012, and the references of the included studies were also retrieved to collect the randomized controlled trials (RCTs) on rTMS in treating stroke patients with motor dysfunction. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Then meta-analysis was performed using RevMan 5.0.2 software, and evidence quality and recommendation level were assessed using the GRADE system. Results A total of 11 RCTs involving 376 patients were included. The results of meta-analysis (including 3 RCTs, low quality) showed that, compared with the routine rehabilitation treatment, 2 to 4 weeks of rTMS was much beneficial to stroke patients with motor dysfunction, with significant differences (WMD=11.02, 95%CI 2.56 to 19.47). The other 8 studies only adopted descriptive analysis accordingly. Conclusion It is still uncertain of the effectiveness of rTMS in improving motor dysfunction of stroke patients, so rTMS should be applied with caution in clinic.

  • Efficacy of Mental Practice on Rehabilitation of Hand Function in Patients with Post-stroke: A Systematic Review

    Objective?To evaluate Mental Imagery on rehabilitation of functions in patients with stroke. Methods?Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMbase, PEDro (www.pedro.org.au), OpenSIGLE, National Technical Information Service (NTIS), CNKI, VIP, Wanfang Data, and CBM were searched for the Randomized controlled trials (RCTs) of Mental Imagery on rehabilitation of functions in patients with stroke from the date of establishment of the databases to October 2010. The bibliographies of the included studies were searched, too. Three independent researchers evaluated the included studies using GRADE. The extracted data were analyzed by RevMan 5.0.25 and GRAEDprofiler 3.2.2. Results?A total 16 trials were discovered. Meta-analyses showed that at the end of 4th, 6th, and 8th, compared with conventional rehabilitation, the mental practice increased the score measured by FMA (WMD=7.81, 95%CI 1.96 to 13.65; WMD=13.89, 95%CI 4.53 to 23.25; and WMD=9.45, 95%CI 3.67 to 15.23, respectively) and ARAT (WMD=5.70, 95%CI 3.17 to 8.22, P=0.30). The 4 outcomes were all of low quality in the GRADE system. Conclusion?The current evidence shows mental practice could improve the upper limb function in patients after stroke, and the side effects of mental practice are not found in meta-analyses. Compared with other rehabilitative therapies, it is simper, of lower input costs, and of low operating costs. The clinicians should recommend it. Due to the limitations of the included studies, more large-sample, high-quality RCTs are required.
