标题： An Optical Measurement System for Open-Source Tracking of Jaw Motions

摘要： 精确跟踪下颌运动学对于诊断影响咀嚼系统的各种骨骼肌肉和神经肌肉疾病，以及推进如下颌外骨骼等康复设备的研究至关重要，这是一个研究较少的领域。我们引入了一种开源、低成本、精确、非侵入性和生物相容性的下颌跟踪系统，该系统基于光学运动捕捉技术，以满足对可访问和可适应的研究工具的需求。该系统涵盖了从数据采集、处理和运动学分析到过滤、可视化和数据存储的完整流程。我们在四名参与者执行各种下颌运动的实验中评估了其性能和可行性。该系统展示了可靠的运动学跟踪，估计精度为$(182 \pm 47) {\mu}m$和$(0.126 \pm 0.034) {\deg}$。因此，该系统的开源性质及其与商业系统的实用性相当，使其适用于许多研究和开发环境，特别是用于下颌外骨骼和定制诊断协议的集成与设计等应用。该完整系统可在GitHub上获取，旨在促进颞下颌关节疾病研究和下颌辅助技术的创新。 显示英文摘要

摘要： Precise tracking of the jaw kinematics is crucial for diagnosing various musculoskeletal and neuromuscular diseases affecting the masticatory system and for advancing rehabilitative devices such as jaw exoskeletons, a hardly explored research field, to treat these disorders. We introduce an open-source, low-cost, precise, non-invasive, and biocompatible jaw tracking system based on optical motion capture technology to address the need for accessible and adaptable research tools. The system encompasses a complete pipeline from data acquisition, processing, and kinematic analysis to filtering, visualization, and data storage. We evaluated its performance and feasibility in experiments with four participants executing various jaw movements. The system demonstrated reliable kinematic tracking with an estimated precision of $(182 \pm 47) {\mu}m$ and $(0.126 \pm 0.034) {\deg}$. Therefore, the open-source nature of the system and its utility comparable to commercial systems make it suitable for many research and development contexts, especially for applications such as the integration and design of jaw exoskeletons and customized diagnostic protocols. The complete system is available at GitHub with the aim of promoting innovation in temporomandibular disorders research and jaw assistive technology.
