Measurement of three-dimensional (3D) knee joint angle outside a laboratory is of benefit in clinical examination and therapeutic treatment comparison. Although several motion capture devices exist, there is a need for an ambulatory system that could be used in routine practice. Up-to-date, ...
A simple method based on a leg movement is proposed here to align two inertial measurement units fixed on the thigh and shank segments. Based on the combination of the former alignment and a fusion algorithm, the three-dimensional knee joint angle is measured and compared with a magnetic ...
Methods Ten able-bodied participants were outfitted with three inertial measurement units during triple single-leg hop trials. 3D knee and ankle angles were calculated using the strap-down integration method, and results were compared with camera-based joint angles. Additionally, knee and ankle range...
Inset: L in function of angle (blue) and diameter due to muscle movement (orange); (b) knee movement. Figure 2b gives the dynamic measurement of the knee moving from full extension to fully bent for two different knit implementations. The crinkle-related memory effect is apparent at the ...
Figure 1.Measurement technique of the femoral head sphericity. A indicates the radius of the smallest circle that fits within the contour of the femoral head. B indicates the radius of the largest circle which encloses the femoral head. The ratio is calculated by A divided by B. ...
