多靶点交替tDCS联合任务导向性训练对运动发育迟缓儿童运动功能及表面肌电活动的影响
Effects of multi-target alternating transcranial direct current stimulation combined with task-oriented training on motor function and surface electromyographic activity in children with motor developmental delay
摘要
Abstract
Objective To explore the effects of multi-target alternating transcranial direct current stimulation(tDCS)combined with task-oriented training on motor function and surface electromyographic activity in children with motor developmental delay.Methods A total of 80 children with motor developmental delay admitted to Ganzhou Maternal and Child Health Hospital from January 2023 and February 2024 were selected and divided into control group and observation group using a random number table,40 cases in each group.Control group received task-oriented training alone,while observation group received multi-target alternating tDCS combined with task-oriented training.The total clinical effective rate,scores on the Peabody developmental motor scales-2(PDMS-2),Berg balance scale(BBS)scores,and the difference in root mean square(RMS)values of bilateral limb surface electromyographic signals before and after treatment were compared between two groups.Results The total effective rate in observation group was significantly higher than that in control group(85.00%vs.62.50%,P<0.05).After treatment,compared with control group,observation group showed increases of 3.27 points in the gross motor quotient,4.76 points in the fine motor quotient,and 3.68 points in the total motor quotient of the PDMS-2,as well as a 2.44-point increase in the BBS score,with all differences being statistically significant(P<0.05).Additionally,the RMS differences of surface electromyography in the bilateral biceps brachii and triceps brachii decreased by 1.57 μV and 2.60 μV,respectively,while those in the bilateral hamstrings and quadriceps decreased by 0.83 μV and 0.68 μV,respectively,with all differences being statistically significant(P<0.05).Conclusion Multi-target alternating tDCS combined with task-oriented training can effectively improve motor function,balance ability,and surface electromyographic features in children with motor developmental delay,and enhance the symmetry of bilateral limb muscle activity.关键词
