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 biomechanical model of the lumbosacral joint during lifting activities
(Elsevier, 1985)
A biomechanical model of the lumbosacral region was constructed for the purpose of systematically studying the combined stresses and strains on the local ligaments, muscles and disc tissue during sagittal plane two-handed ...
The mechanical properties of human tibial trabecular bone as a function of metaphyseal location
(Elsevier, 1983)
Experimental determination of the elastic modulus and ultimate strength of human tibial trabecular bone as a function of metaphyseal location is presented.A 1 cm cubic matrix with planes parallel to the subchondral plate ...
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 ...
The mechanical properties of trabecular bone: Dependence on anatomic location and function
(Elsevier, 1987)
In 1961, Evans and King documented the mechanical properties of trabecular bone from multiple locations in the proximal human femur. Since this time, many investigators have cataloged the distribution of trabecular bone ...
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 ...
