- Abstract: OBJECTIVE:To systematically evaluate the efficacy of transcranial direct current stimulation on the motor function of patients with Parkinson's disease,and to compare the efficacy of transcranial direct current stimulation at different targets on the motor function of patients with Parkinson's disease,so as to provide a theoretical basis for the target selection of transcranial direct current stimulation in clinical practice. METHODS:Cochrane Library,PubMed,Web of Science,CNKI,VIP,WanFang Data were retrieved for randomized controlled trials on the improvement of motor function in patients with Parkinson's disease by transcranial direct current stimulation published from the database inception to January 2023.The keywords were"Parkinson,transcranial direct current stimulation"in English and Chinese.The quality of the included studies was evaluated using the Cochrane 5.1.0 risk of bias assessment tool and the PEDro scale.Meta-analysis of outcome indicators was performed using RevMan 5.4 and Stata 17.0 software. RESULTS:Fifteen randomized controlled trials were finally included,and the PEDro scale showed that all were high-quality or very high-quality studies.Meta-analysis showed that transcranial direct current stimulation significantly improved Unified-Parkinson Disease Rating Scale part III score[mean difference(MD)=-2.49,95%confidence interval(CI):-4.42 to-0.55,P<0.05),step frequency score(MD=0.07,95%CI:0.03-0.11,P<0.05)and step speed score(MD=0.02,95%CI:0.00-0.05,P<0.05),but not for Berg Balance Scale scores(MD=2.57,95%CI:-0.74 to 5.87,P>0.05).Network Meta-analysis probability ranking:In terms of Unified-Parkinson Disease Rating Scale part III scores,the probability ranking results of target stimulation efficacy were dorsal lateral prefrontal cortex(52.4%)>primary motor cortex(45.8%)>central point of the brain(1.8%)>conventional rehabilitation(0%);in terms of gait frequency scores,the probability probability ranking results of target stimulation efficacy were cerebellum(50.1%)>central point of the brain(45.8%)>dorsal lateral prefrontal cortex(3.9%)>primary motor cortex(0.2%)>conventional rehabilitation(0%);in terms of gait speed scores,the probability ranking results of target stimulation efficacy were cerebellum(64.8%)>dorsal lateral prefrontal cortex(23.8%)>central point of the brain(9.4%)>primary motor cortex(1.7%)>conventional rehabilitation(0.4%);in terms of Berg Balance Scale scores,the probability ranking results of target stimulation efficacy were cerebellum(77.4%)>dorsal lateral prefrontal cortex(20.7%)>central point of the brain(0.7%)>conventional rehabilitation(0.2%). CONCLUSION:Transcranial direct current stimulation significantly improves motor function of patients with Parkinson's disease,with better motor coordination in the dorsolateral prefrontal cortex and better walking and balance in the cerebellum.
