BACKGROUND CONTEXT The role of biomechanical workplace factors in spine loading has been well documented. However, our understanding of the role of psychosocial and individual factors in producing spine loads is poorly understood. Even less is understood about the relative contribution of these factors with respect to kinematic, kinetic and muscle activity responses, as well as spine loading. ...

Background and purpose - The proximal femur locking compression plate (PF-LCP) is a new concept in the treatment of hip fractures. When releasing new implants onto the market, biomechanical studies are conducted to evaluate performance of the implant. We investigated the relation between biomechanical and clinical studies on PF-LCP. Methods - A systematic literature search of relevant biomechan...

  This study was designed to elucidate the possible difference between supa and ethicon.nylon in suturing rat skin.75 female spragne-dawley albino rats with mean weight 250 g were used and randomly divided into three groups of 30,30 and 15 rats.in 60 rats anesthesea was induced by ketamin and xylazin.followed by surgical preparation , a 5 cm abdominal skin incision was made and sutured by simp...

BACKGROUND Female athletes have a higher rate of anterior cruciate ligament (ACL) injury than males from adolescence and into maturity, which is suggested to result from sex-specific changes in dynamic movement patterns with maturation. Few studies have studied movement strategies and response to fatigue in children. PURPOSE To evaluate the effect of fatigue on biomechanical variables associa...

OBJECTIVE To review the literature that evaluates the influence of trunk motion on trunk strength and structural loading. BACKGROUND In recent years, trunk dynamics have been identified as potential risk factors for developing low-back disorders. Consequently, a better understanding of the underlying mechanisms involved in trunk motion is needed. METHODS This review summarizes the results o...

The Defence Research and Development Canada--Toronto managed a collaborative team of designers, biomechanists, ergonomists and military stakeholders in the development of a new personal load carriage (LC) system for the Canadian Forces. Ergonomics design principles using objective measurement tools and user-centred feedback from soldiers were considered essential to system development. The purp...

BACKGROUND Right ventricular (RV) diastolic function has been associated with outcomes for patients with pulmonary hypertension; however, the relationship between biomechanics and hemodynamics in the right ventricle has not been studied. METHODS AND RESULTS Rat models of RV pressure overload were obtained via pulmonary artery banding (PAB; control, n=7; PAB, n=5). At 3 weeks after banding, RV...

Using recruitment manoeuvres in acute lung injury remains a controversial issue because no convincing outcome data support their general use, although many physiological studies have demonstrated beneficial effects on lung compliance, end-expiratory lung volume and gas exchange. One of the reasons why physiologically meaningful observations do not translate into clear clinical benefit could be ...

Objectives. Femur strength index (FSI) has been previously described as a reliable measure of femur fracture risk in a fall. FSI computation requires software associated with bone densitometry equipment and incorporates measures of bony structural integrity. Because such software is not universally available, in the present study, we describe the evaluation of the biomechanical predictors of fe...
