个性化的手指运动代表了手部灵活性的关键特征。然而，我们对获得这种运动技能的机制的理解是有限的。本研究旨在确定日常运动训练对获得个性化手指运动的影响。10个音乐天真的人进行钢琴练习连续4天，手运动学进行了评估，使用运动捕捉系统。结果表明，随着练习，手指之间的运动协变减少，特别是在无名指和小指。这种下降在练习前独立控制力较低的一对手指中更为明显。此外，几个手指对表现出促进运动的独立性时，提供了视觉反馈（VFB）的运动动作的节奏准确性，每次练习。结果提供了证据，通过钢琴练习过程中灵巧的手使用，这表明与手指运动的独立控制相关的神经肌肉系统的塑性适应的个性化手指运动的增强。(C)2014年IBRO。由爱思唯尔有限公司出版。保留所有权利。
Individuated finger movements represent a key feature of hand dexterity. However, our understanding of mechanisms underlying the acquisition of this motor skill is limited. The present study aimed to identify the effects of daily motor training on acquisition of individuated finger movements. Ten musically naive individuals performed piano practice for 4 successive days, and hand kinematics were evaluated using a motion capture system. The results showed a decrease in movement covariation across fingers with practice, particularly at the ring and little fingers. The decrease was more pronounced in the pair of fingers with lower independent control prior to the practice. Furthermore, a few finger pairs demonstrated facilitated movement independence when the subject was provided with visual feedback (VFB) regarding the rhythmic accuracy of motor actions following each practice. The results provide evidence for the enhancement of individuated finger movements through dexterous hand use during piano practice, which suggests plastic adaptation of the neuromuscular system associated with independent control of finger movement.
