Conditions

osteoarthritis

Interventions

We do the following examinations:Physical examination. For example, height and weight.A movement analysis, in which the participant makes a number of movements. We will use one or more of skin markers
An MRI scan, where people lie still for 20-60 minutes, and/or a special CT (photon-counting CT) scan, where they lie still for about 10 minutes.&nbsp

Exclusion criteria

Exclusion criteria: Reported pain in the ankles, hips, or lower back that might affect mobility or function Contraindication to full weight bearing: recent injury, surgery or diagnosis to the lower extremity for which a physician has restricted weight bearing status to less than weight bearing as tolerated (e.g., feather weight bearing, non-weightbearing) Any other diagnosis or suspected condition that impacts mobility or function (e.g., inflammatory conditions, neurologic conditions)  Any contraindication to undergoing imaging including MRI, PCCT or fluoroscopy (e.g., metal implants, pregnancy) Unable to communicate in either Dutch or English  

Design outcomes

Primary

MeasureTime frame
Our aim is to develop, refine, optimize and adapt a library of data collection protocols and data processing workflows to measure knee kinematics and kinetics during different functional tasks. This aim involves technical development and therefore does not involve specific research questions that require statistical analyses.

Secondary

MeasureTime frame
Secondary study parameters measured will depend on each specific protocol/workflow developed. In addition to kinematics and kinetics, we may also evaluate reliability, validity, or feasibility of the models. This would include statistical tests like intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs), interclass correlation coefficients (e.g. Pearson correlations), root mean square errors (RMSEs), and Bland Altman plots. The evaluation of feasibility is more qualitative, and includes measurements of time to collect data, time to process and analyse data, potential for automation of workflow steps (e.g. segmentation, registration), costs and skills required to perform complete protocols/workflows, and robustness of results when comparing models with varying levels of complexity, automation, or personalization.
