Kinematic and kinetic data recorded with an instrumented shoulder prosthesis

Wat erin zit

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 in-vivo 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 in-vivo 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. …
