Kinematic and kinetic data recorded with an instrumented shoulder prosthesis

Data drawn from experiments performed in 2009 in a joint project between TU Delft, VU Amsterdam and Charité Berlin.An instrumented shoulder endoprosthesis developed by Charité was used for <em>in-vivo</em> measurement of the glenohumeral joint contact forces on the humeral head of the human shoulder. The contact forces and moments are measured in the local coordinate system of the instrumented shoulder implant and transferred to the glenoid surface. Motion data as well as the <em>in-vivo</em> glenohumeral joint contact forces and moments of six patients with an instrumented shoulder hemiarthroplasty were recorded while performing quasi-static tasks, loaded and unloaded dynamics tasks, force tasks, and ADL tasks. Four patients (S4R, S5R, S7R, and S8R) also performed wheelchair propulsion on a treadmill with different speeds. Processed motion data and patient-specific CT-images were used to calculate the transformations needed to transform force and moment data from the implant-based local coordinate system (in which forces and moments were originally measured) to a glenoid-based system. The data set comprises contact forces, surface EMG data and kinematic data collected with an Optotrak system. Also added are the measurement protocol and data processing programs<br>On 12-08-2024 we added imaging data for as far as available<br>See also https://orthoload.com/publications/shoulder/<br>

本数据集的数据源自2009年代尔夫特理工大学（TU Delft）、阿姆斯特丹自由大学（VU Amsterdam）与柏林夏里特医学院（Charité Berlin）联合开展的实验项目。柏林夏里特医学院开发的带传感装置的肩关节内置假体，用于体内（in-vivo）测量人类肩关节肱骨头处的盂肱关节接触力。接触力与力矩在该带传感装置的肩关节植入物的局部坐标系中完成采集，并转换至关节盂表面坐标系。本研究记录了6名接受半肩关节置换术且植入传感装置的患者，在执行准静态任务、负载与非负载动态任务、肌力任务以及日常生活活动（Activities of Daily Living, ADL）任务时的运动数据，以及体内盂肱关节接触力与力矩。其中4名患者（S4R、S5R、S7R及S8R）还在不同速度的跑台上完成了轮椅推进任务。经处理的运动数据与患者专属CT影像被用于计算坐标变换，以将原本基于植入物局部坐标系（即原始力与力矩的采集坐标系）测得的数据，转换至关节盂坐标系。本数据集包含接触力、表面肌电（surface EMG）数据，以及通过Optotrak系统（Optotrak system）采集的运动学数据；此外还收录了测量方案与数据处理程序。2024年8月12日，我们补充了现有可获取的影像数据。详情可参阅https://orthoload.com/publications/shoulder/
