锁舞（Lock dance）是一种流行的老派街舞，其特点是通过关节和肌肉的复杂控制和协调，做出尖锐、突然和孤立的身体动作。本研究旨在基于运动学运动协同分析来理解复杂的锁舞动作。由三名经验丰富的舞者表演的锁舞动作用无标记人类动作捕捉技术进行测量。利用主成分分析（PCA）对运动协同效应进行了识别和总结。基于协同模式及其激活，分析了十种锁舞基本动作的动作复杂性、联合贡献和动作协调性。结果增强了我们对复杂舞蹈动作的理解，并为未来的应用迈出了一步，例如舞蹈技巧或伤害风险评估。
Lock dance, or locking, is one of the popular old-school street dance styles featuring sharp, sudden, and isolated body movements through intricate control and coordination of joints and muscles. This work aims to understand the complex lock dance motions based on kinematic motor synergy analysis. Lock dance motions performed by three experienced dancers were measured with a markerless human motion capture technique. The motor synergies were identified and summarized using principle component analysis (PCA). The motion complexity, joint contributions, and motor coordination of ten basic lock dance choreographies were analyzed based on the synergy patterns and their activations. The results enhance our understanding of complex dance motions and serve as a step toward future applications to, e.g. dance skill or injury risk assessments.
