The capture of three dimensional body movement, or gait analysis, provides essential information on human kinematics and locomotion, and is used for both identifying patient pathologies and for quantifying clinical problems such as joint instability after e.g. cruciate ligament injury or reconstruction. Using a number of mathematical tools for determining the motion of the underlying skeletal structures from the measurement of markers attached to the skin, we aim to assess patient function, specifically at the knee, and therefore improve our understanding of the interaction between internal loading, kinematics, instability and pain. In order to perform these advanced kinematic and force tests, a 3D motion analysis system (six infra-red cameras) and force platforms allow the capture of body segment motion during a variety of activities of daily living
Within the new Center for Sports Medicine and Sports Science Berlin (CSSB), a collaborative research center of the Julius Wolff Institute and the Humboldt University of Berlin, we aim to develop solutions for quantifying patient function by assessing both the external (body) and internal (skeletal) motion, as well as muscular control mechanisms. A key factor in the interaction between research and clinical applications is the daily integration of Charité patients into the research studies, facilitated by the immediate vicinity of the CSSB to the patient house of the Charité. The labs are extremely user-friendly, and set up for analyses of both patients as well as top athletes in a pleasant working environment.
A strong partnership between Musculoskeletal Biomechanics and the group Instrumented Implants, allows the direct kinematic analysis of knee patients and an essential link for validation of the musculoskeletal models. Together, this combination of core competencies provides a strong partnership, allowing measurement, calculation and validation of internal forces in a unique group of patients.
3D body motion can be captured using reflective markers attached to the skin and measured using infra-red cameras. By extracting the underlying skeletal motion, analyses of the changes in internal loading conditions and joint movement can provide a quantification of pathology to aid clinical assessment.
Force, moment and angular velocity measurements provide an assessment
