The aims of this study were to ) evaluate proximal-to-distal sequencing (PDS) in pianists' attack and release movements during pressed- keystrokes, and ) investigate if trunk motion facilitates PDS of upper-limb movements. Nine expert pianists performed a series of loud pressed- keystrokes. Kinematic data was recorded with a 3 D motion capture system. PDS was assessed by comparing temporal organization of peak velocities from the pelvis to the wrist. Evidence of PDS was found across the kinematic chain. Pianists' use of PDS differed mainly between scapula and shoulder movements. Trunk motion facilitated PDS by increasing anticipatory shoulder movements and by preceding shoulder-girdle attack and release movements. Implications might relate to research on performance optimization and injury prevention strategies.
（i）评估钢琴家按下琴键时的攻击和释放动作的近端到远端顺序（PDS）；（ii）研究躯干运动是否有助于上肢运动的 PDS。九位专家钢琴家进行了一系列响亮的按下琴键动作。运动学数据通过 3D 运动捕捉系统记录。通过比较骨盆到手腕的峰值速度的时间组织来评估 PDS。在运动链中发现了 PDS 的证据。钢琴家对 PDS 的使用主要在肩胛骨和肩部运动之间有所不同。躯干运动通过增加肩部的预备性运动，并使肩部和肩胛带的攻击和释放运动提前，从而促进 PDS。其影响可能与性能优化和损伤预防策略的研究有关。
