Development of an Assessment System for Camera-Based Motion Analysis
Zusammenfassung der Studie
In the rehabilitation of children and adolescents with neurological issues, more precise and objective measurement methods are increasingly being used. For this purpose, we have developed a method to capture movements in 3D. We have conducted initial studies that show that the motion capture is quite accurate. Now we want to know how to best evaluate the data. We aim to try different methods to determine these measurements. Then we want to find the best method. We test healthy children, adolescents, and young adults as well as patients. Participants will perform various tasks (e.g., sitting upright and extending both arms forward, leaning the upper body forward, sitting or lying still). The tasks come from tests that assess trunk control or dyskinesia, which is a movement disorder characterized by involuntary muscle movements and spasms. Everything is filmed with a special camera. Afterwards, we will test different methods to evaluate the movements.

Untersuchte Intervention
We use a single RGB-D camera (Red-Green-Blue and Depth), namely the Kinect camera (Azure Kinect Developer Kit or AKDK) [Microsoft2024] or the technically identical Orbbec Femto Bolt [Orbbec2024]. These cameras are cost-effective, portable, and provide 3D information about the scene, thus having the potential to enable high-quality 3D motion tracking with a single camera. We have developed a method for tracking 3D full-body movements of children using a single RGB-D camera, referred to as SMPLify-KiDS. In this study, we will investigate how meaningful and psychometrically sound measurements for outcomes can be derived from these recordings.
