神经假体可用于恢复高位脊髓损伤患者的上肢运动。开发和评估此类设备的命令和控制方案通常需要实时的“患者在环”实验。一个实时的，三维的，上肢的肌肉骨骼模型已被开发用于在模拟环境中使用，以允许这样的测试进行非侵入性。该模型提供了可以在虚拟现实环境中向用户显示的人类手臂动态的实时反馈。该模型具有三个自由度的盂肱关节以及肘关节屈曲/伸展和旋前/旋后，并包含分为多个元素的肩关节和肘关节的22块肌肉。该模型能够在普通的桌面硬件上以真实的时间运行，并且表明可以使大规模的3D模型以真实的时间运行。这是一个实时的，整个手臂模型，将形成一个动态的手臂模拟器的一部分，用于开发，测试和用户培训的神经假体系统的先决条件。
Neuroprostheses can be used to restore movement of the upper limb in individuals with high-level spinal cord injury. Development and evaluation of command and control schemes for such devices typically requires real-time, “patient-in-the-loop” experimentation. A real-time, three-dimensional, musculoskeletal model of the upper limb has been developed for use in a simulation environment to allow such testing to be carried out non-invasively. The model provides real-time feedback of human arm dynamics that can be displayed to the user in a virtual reality environment. The model has a three degree-of-freedom gleno-humeral joint as well as elbow flexion/extension and pronation/supination, and contains 22 muscles of the shoulder and elbow divided into multiple elements. The model is able to run in real time on modest desktop hardware and demonstrates that a large-scale, 3D model can be made to run in real time. This is a prerequisite for a real-time, whole arm model that will form part of a dynamic arm simulator for use in the development, testing and user training of neural prosthesis systems.
