Development of a Protocol to Quantify In-vivo Kinematics of the Foot and Ankle
Description
The presentation focuses on the kinematics of the foot and ankle, outlining a research study that employs motion capture and biplane video X-ray techniques to analyze joint movements. Claire Brockett introduces the topic before David Williams takes over, noting that much of the work was conducted by undergraduate Laura Esquivel from Cardiff University.
The study aims to quantify in-vivo kinematics of the foot and ankle by developing a protocol for capturing data through a specialized high-speed dynamic biplane X-ray system in conjunction with motion capture. The methodology includes recruiting healthy volunteers, conducting MRI imaging to produce 3D models of bones, and utilizing custom-built apparatus for capturing the necessary motions.
Pulsed X-rays were taken at a low dose to observe movement, synchronizing with detailed motion capture methods using the AnyBody marker set. Initial results indicate discrepancies between the biplane X-ray and motion capture data, particularly regarding the subtalar joint's range of motion. Future studies will aim to improve the accuracy of measurements and incorporate additional technologies, including foot pressure sensors, to enhance the analysis of in-vivo kinematics.
As the session concludes, participants engage in a Q&A discussing potential improvements in marker technology, the influence of marker movement on accuracy, and the integration of virtual markers based on bone data.
