High-pass filtering to remove electrocardiographic interference from torso EMG recordings
(Elsevier, 1993-01)
SummaryRemoval of electrocardiographic (ECG) contamination of electromyographic (EMG) signals from torso muscles is often attempted by high-pass filtering. This study investigated the effects of the cut-off frequency used ...
Direct calculation of the surface-to-volume ratio for human cancellous bone
(Elsevier, 1993-08)
There are many diseases which cause detrimental changes in the trabecular structure of cancellous bone, leading to mechanical failure of the tissue. One approach to understanding the mechanisms of these diseases is to ...
The elastic moduli of human subchondral, trabecular, and cortical bone tissue and the size-dependency of cortical bone modulus
(Elsevier, 1990)
The elastic moduli of human subchondral, trabecular, and cortical bone tissue from a proximal tibia were experimentally determined using three-point bending tests on a microstructural level. The mean modulus of subchondral ...
Lumbar muscle size and locations from CT scans of 96 women of age 40 to 63 years
(Elsevier, 1990-02)
Computed tomography scans of 96 women aged between 40 and 63 years were systematically measured to determine torso muscle moment arms and cross-sectional areas at L2/L3, L3/L4 and L4/L5 disc levels. The major findings were ...
A comparison of the fatigue behavior of human trabecular and cortical bone tissue
(Elsevier, 1992-12)
The fatigue properties of trabecular bone tissue (single trabeculae) and similarly sized cortical bone specimens from human tibia were experimentally determined on a microstructural level using four-point bending cyclic ...
A homogenization sampling procedure for calculating trabecular bone effective stiffness and tissue level stress
(Elsevier, 1994-04)
A homogenization sampling procedure is introduced which allows computation of effective trabecular bone stiffness and individual trabecula level stress based on precise models of trabecular bone architecture. Three-dimensional ...
Validation of a biodynamic model of pushing and pulling
(Elsevier, 1991)
Pushing and pulling during manual material handling can increase the compressive forces on the lumbar disc region while creating high shear forces at the shoe-floor interface. A sagittal plane dynamic model derived from ...
Displacements of the menisci under joint load: An in vitro study in human knees
(Elsevier, 1994-04)
The purpose of this study was to test whether the menisci displace under joint compression combined with internal-external torques and anterior-posterior forces at fixed flexion angles. We further determined differences ...
Quantitative interpretation of lumbar muscle myoelectric signals during rapid cyclic attempted trunk flexions and extensions
(Elsevier, 1994-02)
The quantitative relationship between lumbar myoelectric signals (MES) and rapidly varying isometric trunk muscle forces was investigated. Ten young adult males were asked to cycle harmonically between attempted trunk ...
Do bone ingrowth processes produce a globally optimized structure?
(Elsevier, 1993)
A topology optimization program was applied to test the hypothesis that bone adaptation to porous coated implants produces a structure which minimizes the global strain energy density. The program was used to predict the ...
