Validating Knee Varus Alignment Measurements Using Markerless Motion Capture

Geriatrics, 2023
This study aimed to determine the validity of specific knee varus alignment measurement methods. We measured the femorotibial angle (FTA) using radiography and optical motion capture and validated the FTA measurement using markerless motion capture.

Marker Data Enhancement for Markerless Motion Capture. [PDF]

IEEE Trans Biomed Eng
Abstract Objective Human pose estimation models can measure movement from videos at a large scale and low cost; however, open-source pose estimation models typically detect only sparse keypoints, which leads to inaccurate joint kinematics.

Evaluation of 3D Markerless Motion Capture System Accuracy during Skate Skiing on a Treadmill

Bioengineering
In this study, we developed a deep learning-based 3D markerless motion capture system for skate skiing on a treadmill and evaluated its accuracy against marker-based motion capture during G1 and G3 skating techniques. Participants performed roller skiing
