Abstract: A biplanar videotaping system is used to generate spatial kinematic data of an upper extremity motion. The technique is based upon the characterization of each segment by four points in ...

Abstract: A computer-aided analysis procedure is developed to obtain biomechanical information for unassisted and assisted upper extremity systems. An automated assembly procedure is derived which determines ...

Abstract: A finite element (FE) based scheme for modeling facet articulation in a spinal motion segment is proposed. The algorithm presented models the facet articulation as a nonlinear progressive contact ...

Abstract: In certain dynamic problems, the determination of the applied torques at the joints from the measured displacement-time history is of interest, and is known as the inverse dynamic problem. A ...

Abstract: A software shell called “Learning Shell for Iterative Design,” L’SID, has been developed in conjunction with a simple data matrix, the “learn table.” Histories of design are utilized in aiding ...

Abstract: Scanning acoustic microscopy (SAM) was used in the evaluation of bone remodeling around a cylindrical unicortical defect. SAM is a technique for the nondestructive evaluation of materials, and ...

Abstract: In this study, a finite element model of a vertebral body was used to study the load-bearing role of the two components (shell and core) under compression. The model of the vertebral body ...

Abstract: A nonlinear micromechanical model for two-dimensional irregular hexagonal foams has been developed that allows for anisotropy in morphology and/or material. Based upon the orientation, cross section, ...

Abstract: A parametric study was conducted to compare the resistance to shear force provided by three surgical implantation techniques and three endplate designs for use with a polymeric lumbar intervertebral ...
