中文摘要:
      目的:研究短期训练对正常人下颌和手指运动的准确度和精确度的影响。方法:纳入20例正常受试者,在30 min的训练前后分别记录10次连续的下颌和手指运动,计算其准确度和精确度并进行比较。结果:短期训练后下颌和手指运动的准确度与精确度均明显提高(P<0.05),手指运动的提高幅度更大(P<0.05)。结论:短期训练可以提升下颌运动与手指运动表现,这验证了运动控制机制中存在着显著的神经可塑性现象。脊神经支配的手指运动与三叉神经支配的下颌运动在运动学习能力上存在差异,短期运动训练对手指运动的提高更大。
英文摘要:
      Objective:This study aims to investigate effects of short?term training on accuracy and precision of jaw and finger movement in healthy Chinese. Methods:Twenty healthy volunteers were recruited in this study. We recorded 10 consecutive jaw and finger movements separately before and after a 30?minute motor training and then calculated and compared their accuracy and precision. Results:Accuracy and precision of jaw and finger movements were significantly improved after short?term training(P<0.05),and finger movement improved more than jaw movement(P<0.05). Conclusion:Short?term training can improve the performance of jaw and finger movement,which demonstrates that neuroplasticity occurs in motor control. Spinally innervated finger movement differs from trigeminally innervated jaw movement in motor learning. Short?term motor training helps to improve finger movement.
