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 ...
Biomechanics of reactions to impending falls
(Elsevier, 1988)
Responses of 11 young adult males, initially standing, to support surface forward accelerations of 0.18 g were investigated. In response to the impending falls this stimulus initiated, body segment motions and myoelectric ...
Mobility impairment in the elderly: Challenges for biomechanics research
(Elsevier, 1992-05)
The problems of mobility impairment in the elderly constitute new and major challenges for biomechanics research. This paper outlines what some of the important problems are, discusses the relevance of biomechanics research ...
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 ...
Optimization of skeletal configuration: Studies of scoliosis correction biomechanics
(Elsevier, 1991)
A scheme for optimizing configurations in models of skeletal structures is presented. Use of the scheme is illustrated through determination of biomechanically optimal correction of a right-thoracic scoliosis by passive ...
The limitations of canine trabecular bone as a model for human: A biomechanical study
(Elsevier, 1989)
Distal canine femurs were sectioned into 8mm cubic specimens. Orthogonal compression tests were performed to preyield in two or three directions and to failure in a third. Apparent density and ash weight density were ...
Biomechanical analyses of rising from a chair
(Elsevier, 1992-12)
Quantification of the biomechanical factors that underlie the inability to rise from a chair can help explain why this disability occurs and can aid in the design of chairs and of therapeutic intervention programs. ...
Dynamics of gas bubbles in whole blood and plasma
(Elsevier, 1971-03)
Analytical solutions are obtained for both the radius-time relation and the rate of solution by diffusion of a gas bubble in plasma and whole blood with reduced hemoglobin. If an oxygen bubble is situated in the blood, a ...
Identification of dynamic myoelectric signal-to-force models during isometric lumbar muscle contractions
(Elsevier, 1994-07)
A 14-muscle myoelectric signal (MES)-driven muscle force prediction model of the L3-L4 cross section is developed which includes a dynamic MES-force relationship and allows for cocontraction. Model parameters are estimated ...
