摘要
目的观察高精度经颅直流电刺激(HD-tDCS)不同刺激时机(在线刺激、离线刺激)对健康成年人手指运动技能学习效果的影响。方法2022年3月至11月,在沈阳体育学院招募右利手男性受试者31例,随机分为3组。分别在HD-tDCS在线刺激、离线刺激以及假刺激下,完成顺序视觉等距捏力任务学习,共3 d。观察每天运动技能学习量、运动技能学习总量和速度-精度函数(SAF)。结果各组运动技能学习量均增加,在线刺激组增加最多(F=24.692,P<0.001),且第3天时,显著高于离线刺激组(t=4.732,P<0.001)和假刺激组(t=3.839,P=0.004)。运动技能学习总量:在线刺激组=离线刺激组>假刺激组。在线刺激组SAF高于离线刺激组和假刺激组。结论HD-tDCS刺激可提高健康受试者手指运动技能学习效果,在线刺激效果最佳。
Objective To investigate the effect of high definition transcranial direct current stimulation(HD-tDCS)at different stimulation timings(online and offline)on finger motor skill learning in healthy adults.Methods From March to November,2022,31 right-handed male participants were recruited from Shenyang Sport University and randomly assigned to three groups,who received online,offline or sham HD-tDCS respectively during the three-day sequential visual isometric pinch task learning process.The daily motor skill learning gains,total motor skill learning gains and speed-accuracy function(SAF)were observed.Results The daily motor skill learning gains increased in all the groups,and it was the best in the online group(F=24.692,P<0.001);the learning gains were better in the online group than in the offline group(t=4.732,P<0.001)and the sham group(t=3.839,P=0.004)on the third day.The total motor skill learning gains were ranked as the online group=the offline group>the sham group.SAF data indicated that the online group outperformed both the offline and sham groups.Conclusion HD-tDCS can promote the finger motor skill learning in healthy adults,and online HD-tDCS is more effective.
