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 ...
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 ...
Number of contractions to maintain mass and force of a denervated rat muscle
(Wiley Subscription Services, Inc., A Wiley Company, 2004-07)
Within 5 weeks, denervated extensor digitorum longus (EDL) muscles of rats lose 66% of mass, 91% of force, and 76% of fiber cross-sectional area (CSA). We previously determined the parameters of electrical stimulation for ...
The free autografting of entire limb muscles in the cat: Morphology Supported by grants by the Muscular Dystrophy Association to BMC and JAF and an MDA Postdoctoral Fellowship to SAM.
(Wiley Subscription Services, Inc., A Wiley Company, 1977-08)
Normal or pre-denervated extensor digitorum longus (EDL) muscles were successfully grafted in place of the contralateral EDL muscles in cats. Histological preparations of 57 grafts were examined at intervals from 4 to 170 ...
Isometric and isokinetic back and arm lifting strengths: Device and measurement
(Elsevier, 1988)
This study was conducted to measure isometric (static) and isokinetic (dynamic) back and arm lifting strengths at 20, 60 and 100 cm s-1 of young adults. Ten male and ten female volunteers without a history of back pain ...
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 ...
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 ...
Fast, pseudo-continuous arterial spin labeling for functional imaging using a two-coil system
(Wiley Subscription Services, Inc., A Wiley Company, 2004-03)
A fast, two-coil, pseudo-continuous labeling scheme is presented. This new scheme permits the collection of a multislice subtraction pair in <3 s, depending on the subject's arterial transit times. The method consists of ...
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 ...
