验证了两种非侵入性的方法测量动态三维运动学的人肩胛骨与磁跟踪装置。一种方法是简单地将传感器直接固定在肩峰上，另一种方法是将传感器安装在一个可调节的塑料夹具上，该夹具适合肩胛骨和肩峰。通过与直接将骨针钻入肩胛骨的侵入性方法同时收集的数据进行比较，分别评估了两种方法的并行有效性。基于骨骼和基于皮肤的测量之间的差异表示皮肤运动伪影的估计。每种表面方法的平均运动模式与侵入性技术测量的运动模式相似，特别是在120度以下的仰角。这些结果表明，经过仔细考虑，这两种方法都可以提供合理准确的肩胛骨运动表示，可用于研究肩关节病变，并帮助开发计算模型。
The validation of two noninvasive methods for measuring the dynamic three-dimensional kinematics of the human scapula with a magnetic tracking device is presented. One method consists of simply fixing a sensor directly to the acromin and the other consists of mounting a sensor to an adjustable plastic jig that fits over the scapular spine and acromion. The concurrent validity of both methods was assessed separately by comparison with data collected simultaneously from an invasive approach in which pins were drilled directly into the scapula. The differences between bone and skin based measurements represents an estimation of skin motion artifact. The average motion pattern of each surface method was similar to that measured by the invasive technique, especially below 120 degrees of elevation. These results indicate that with careful consideration, both methods may offer reasonably accurate representations of scapular motion that may be used to study shoulder pathologies and help develop computational models.
