Analysis of cumulative strain in tendons and tendon sheaths
(Elsevier, 1987)
Twenty-five fresh frozen flexor digitorum profundus tendons stratified by sex were subjected to uniaxial step stress and cyclic loads in twelve intact human cadaver hands. By attaching specially designed clip strain gage ...
Biomechanical model calculation of muscle contraction forces: A double linear programming method
(Elsevier, 1988)
This paper presents a novel scheme for the use of linear programming to calculate muscle contraction forces in models describing musculoskeletal system biomechanics. Models of this kind are frequently found in the biomechanics ...
Dynamics of dissolution of gas bubbles or pockets in tissues
(Elsevier, 1972-07)
A mathematical model is developed which describes the dynamic characteristics of gas bubbles in subcutaneous tissues. Consideration is given to both inert and reacting gases. The effects of blood perfusion (or oxygen ...
MR Imaging of Levator Ani Muscle Recovery Following Vaginal Delivery
(Springer-Verlag London Limited, 1999-08)
Our aim was to quantify the changes that occur in the levator ani muscles (LA) after vaginal delivery using magnetic resonance imaging. Fourteen women underwent MRI 1 day postpartum. Six of them were also scanned 1, 2, 6 ...
Effect of altered sensory conditions on multivariate descriptors of human postural sway
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1998-09)
Multivariate descriptors of sway were used to test whether altered sensory conditions result not only in changes in amount of sway but also in postural coordination. Eigenvalues and directions of eigenvectors of the ...
Relaxation phenomenon in lumbar trunk muscles during lateral bending
(Elsevier, 1988-08)
This paper reports myoelectric activity measurements in the lumbar trunk muscles when subjects performed tasks involving various degrees of lateral bending. Biomechanical model analyses were made to estimate the tensions ...
Measurement and significance of three-dimensional architecture to the mechanical integrity of trabecular bone
(Springer-Verlag; Springer-Verlag New York Inc., 1993-02)
The mechanical properties of trabecular bone have been shown to vary significantly with age, anatomic location, and metabolic condition. Efforts towards predicting its behavior have been extensive, and significant relationship ...
Experimental studies of the dissolution of gas bubbles in whole blood and plasma--I. Stationary bubbles
(Elsevier, 1971-07)
Gas bubbles of oxygen, carbon dioxide and nitrogen are injected into the degassed plasma and whole blood. The bubble size is measured at time intervals until the bubble is completely dissolved in the liquid. Physical ...
A model for studies of the deformable rib cage
(Elsevier, 1992-05)
An earlier model for the study of rib cage mechanics was modified so that rib deformity in scoliosis could be better represented. The rigid ribs of that model were replaced by five-segment deformable rits. Literature data ...
A mathematical model for the determination of viscoelastic behavior of brain in vivo--II relaxation response
(Elsevier, 1972-11)
In a recent experiment for determining the mechanical response of brain in vivo. a probe, inserted through scalp, skull and dura, is placed in contact with and normal to the brain, given a prescribed motion, and the time ...
