The Model-Size Effect on Traditional and Modified Tests of Covariance Structures (2007)

Herzog, Walter, Boomsma, Anne, Reinecke, Sven

According to Kenny and McCoach (2003), chi-square tests of structural equation models produce inflated Type I error rates when the degrees of freedom increase. So far, the amount of this bias in...

OBRAZOVNI STANDARD – NOVI INSTRUMENT ZA ŠKOLSKU REFORMU (2006)

Herzog, Walter; Institut Für Pädagogik, Universität Bern, Schweiz

Zusammenfassung -Bildungsstandards gelten als ein viel versprechendes Instrument der Schulreform. Sie definieren messbare Kompetenzen, die als Output (Wirkung) von Bildungsprozessen erwartet...

Simulating the swelling and deformation behaviour in soft tissues using a convective thermal analogy (2002)

Wu, John Z, Herzog, Walter

Abstract Background It is generally accepted that cartilage adaptation and degeneration are mechanically mediated. Investigating the swelling behaviour of cartilage is important because the stress...

Realistic skeletal muscle deformation using finite element analysis (2001)

Robson Lemos, Marcelo Epstein, Walter Herzog, Brian Wyvill

We present a computational model to simulate the skeletal muscle deformation during muscle contraction. This model includes a detailed description of the skeletal muscle architecture, non-linear...

Dynamics of individual sarcomeres during and after stretch in activated single myofibrils.

Rassier, Dilson E, Herzog, Walter, Pollack, Gerald H

It is generally assumed that sarcomere lengths (SLs) change in isometric fibres following activation and following stretch on the descending limb of the force-length relationship, because of an...

Aspects of skeletal muscle modelling.

Epstein, Marcelo, Herzog, Walter

The modelling of skeletal muscle raises a number of philosophical questions, particularly in the realm of the relationship between different possible levels of representation and explanation. After a...

Force enhancement and relaxation rates after stretch of activated muscle fibres

Rassier, Dilson E, Herzog, Walter

The residual force enhancement following muscle stretch might be associated with an increase in the proportion of attached cross-bridges, as supported by stiffness measurements. In this case, it...

ACCELERATIONS RECORDED FROM THE SPINOUS PROCESSES DURING SPINAL MANIPULATIVE TREATMENTS OF THE THORACIC SPINE

Herzog, Walter, Suter, Esther, Conway, Philip J.

The purpose of this study was to identify the frequency components of accelerations measured on the spinous processes of vertebrae caused by chiropractic treatments, and to speculate as to the origin...

Excursion is important in regulating sarcomere number in the growing rabbit tibialis anterior

Koh, Timothy J, Herzog, Walter

The mechanical signal(s) that may be important in regulating the number of sarcomeres in series in skeletal muscle fibres or fascicles (sarcomere number) remain(s) speculative, in part because the in...

Modulation of passive force in single skeletal muscle fibres

Rassier, Dilson E, Lee, Eun-Jeong, Herzog, Walter

In this study, we investigated the effects of activation and stretch on the passive force–sarcomere length relationship in skeletal muscle. Single fibres from the lumbrical muscle of frogs were...

Force enhancement following muscle stretch of electrically stimulated and voluntarily activated human adductor pollicis

Lee, Hae-Dong, Herzog, Walter

For electrically stimulated muscles, it has been observed that maximal muscle force during and after stretch is substantially greater than the corresponding isometric force. However, this observation...

Force depression following muscle shortening of voluntarily activated and electrically stimulated human adductor pollicis

Lee, Hae-Dong, Herzog, Walter

The purpose of this study was to investigate steady-state force depression following active muscle shortening in human adductor pollicis during voluntary and electrically induced contractions....

Biomechanical studies of spinal manipulative therapy

Herzog, Walter

The purpose of this article is to present a review of our research related to spinal manipulative therapy (SMT). The first part of this review will concentrate on studies that were aimed at...

The biomechanics of spinal manipulative treatments

Herzog, Walter

The purpose of this manuscript is to review the work that has been performed on the biomechanics of spinal manipulative treatments (SMT) over the past three years at The University of Calgary. The...

Biomechanical studies of spinal manipulative therapy (SMT): quantifying the movements of vertebral bodies during SMT

Gál, Julianna, Herzog, Walter, Kawchuk, Gregory, Conway, Phillip, Zhang, Yuan-Ting

The relative movements between vertebral bodies T10 and T11, and T11 and T12 were measured during clinical-type SMTs to T11 in unembalmed post-rigor human cadavers, using embedded stainless steel...

Premature deactivation of soleus during the propulsive phase of cat jumping

Kaya, Motoshi, Leonard, Tim R, Herzog, Walter

It has been shown that cat soleus (SOL) forces remain nearly constant despite increases in electromyography (EMG) activity for increasing speeds of locomotion, while medial gastrocnemius (MG) forces...
