Vertical stiffness may contribute to lower-extremity injury risk; however, it is unknown whether athletes with different stiffness levels display differences in biomechanics. This study compared differences in biomechanics between female athletes (n=99) with varying stiffness levels during a repetitive, single-leg, vertical hopping task. Vertical stiffness was calculated as the ratio of peak vertical ground-reaction force to maximum center-of-mass displacement. Tertiles were established using stiffness values, and separate one-way ANOVAs were used to evaluate between-group differences...

This study aimed at investigating the organization of joint angle variability during walking by using the uncontrolled manifold (UCM) theory. We tested two hypotheses: i. the coordinative mechanism underlying joint angle variance during the stance phase is compatible with a kinematic synergy that stabilizes the centre of mass (CoM) position; ii. the walking speed affects the variance components onto and orthogonal to the UCM. Eight healthy subjects (26.0±2.0years old) steadily walked on a treadmill at five normalised speeds (from 0...

In this paper we stress the need for specifically located understandings of the concept of homonationalism, by introducing an analysis of spatial and political power relations dissecting disparate constructions of LGBT arenas. The paper explores three spaces: Tel-Aviv - an urban space of LGBT belonging, Jerusalem - the Israeli capital where being an LGBT individual is problematic both in public and in private spaces and Kiryat-Shmona - a conservative and peripheral underprivileged town in the north of Israel...

PURPOSE: Limb salvage surgery is increasingly used for the treatment of distal femur bone sarcomas. Total knee replacement using megaprosthesis and epiphysis-sparing biologic reconstruction using an allograft are widely used in order to preserve joint motion. We aimed to compare the results of these procedures using gait analysis in patients undergoing limb salvage surgery. METHODS: Fifteen patients were included, nine undergoing allograft with epiphysis sparing (Allograft group) and six undergoing megaprosthesis (Megaprosthesis group)...

The One-Leg Stance (OLS) test is a widely adopted tool for the clinical assessment of balance in the elderly and in subjects with neurological disorders. It was previously showed that the ability to control anticipatory postural adjustments (APAs) prior to lifting one leg is significantly impaired by idiopathic Parkinson's disease (iPD). However, it is not known how APAs are affected by other types of parkinsonism, such as frontal gait disorders (FGD). In this study, an instrumented OLS test based on wearable inertial sensors is proposed to investigate both the initial anticipatory phase and the subsequent unipedal balance...

Heel lifts have been widely used as a conservative treatment for some musculoskeletal problems and complaints. However, the heel rise caused by heel lifts may also affect the plantar pressure distribution and stability during walking. This study aimed to test whether adding an arch support to a heel lift would improve its stability and comfort through comparing the center of pressure (COP) during walking and subjective ratings between heel lifts with and without an arch support. Fifteen healthy male participants were asked to walk along an 8m walkway while wearing high-cut footwear with the control heel lifts and the heel lifts with an arch support...

REVIEW
Christian Fiala, Joyce H Arthur
A widespread assumption has taken hold in the field of medicine that we must allow health care professionals the right to refuse treatment under the guise of 'conscientious objection' (CO), in particular for women seeking abortions. At the same time, it is widely recognized that the refusal to treat creates harm and barriers for patients receiving reproductive health care. In response, many recommendations have been put forward as solutions to limit those harms. Further, some researchers make a distinction between true CO and 'obstructionist CO', based on the motivations or actions of various objectors...

Cerebellar abiotrophy is a hereditary degenerative disorder of the central nervous system in humans and animals. Four male and one female Labrador-retriever pups were presented with clinical signs of head swaying with intention tremor, loss of target oriented movement, wide base stance, forelimb hypermetria, and hindlimb ataxia leading to falling off during ambulation. On histopathologic examination of cerebellum, cerebellar cortical abiotrophy was confirmed with extensive loss of Purkinje cells, diminution of granular layer, relative thickening and foliar gliosis in white matter...

BACKGROUND: Malaria remains a global health issue with the burden unevenly distributed to the disadvantage of the developing countries of the world. Poverty contributes to the malaria burden as it has the ability to affect integral aspects of malaria control. There have been renewed efforts in the global malaria control, resulting in reductions in the global malaria burden over the last decade. However, the development of resistance to artemisinin-based combination therapy threatens the sustainability of the present success in malaria control...

Although a widely used concept in health care, person-centred care remains somewhat ambiguous. In the field of palliative care, person-centred care is considered a historically distinct ideal and yet there continues to be a dearth of conceptual clarity. Person-centred care is also challenged by the pull of standardization that characterizes much of health service delivery. The conceptual ambiguity becomes especially problematic in contemporary pluralistic societies, particularly in the light of continued inequities in healthcare access and disparities in health outcomes...

Dissociative identity disorder (DID) is a chronic post-traumatic disorder where developmentally stressful events in childhood, including abuse, emotional neglect, disturbed attachment, and boundary violations are central and typical etiological factors. Familial, societal, and cultural factors may give rise to the trauma and/or they may influence the expression of DID. Memory and the construction of self-identity are cognitive processes that appear markedly and centrally disrupted in DID and are related to its etiology...

Performance metrics such as speed, cost of transport, and stability are the driving factors behind gait selection in legged locomotion. To help understand the effect of gait on the performance and dynamics of small-scale ambulation, we explore four quadrupedal gaits over a wide range of stride frequencies on a 1.43 g, biologically-inspired microrobot, the Harvard Ambulatory MicroRobot (HAMR). Despite its small size, HAMR can precisely control leg frequency, phasing, and trajectory, making it an exceptional platform for gait studies at scales relevant to insect locomotion...

OBJECTIVE: Rheumatoid cachexia is common in rheumatoid arthritis (RA) patients and develops soon after diagnosis, despite adequate drug therapy. It is associated with multiple adverse effects on body composition, function and mortality. Progressive resistance training (PRT) improves these outcomes but is not widely prescribed outside of a research setting. The aim of the present study was to explore the practicality and effectiveness of providing PRT to patients in a district general hospital within the constraints of existing resources...

K Alex Shorter, Amy R Wu, Arthur D Kuo
Humans tend to walk economically, with preferred step width and length corresponding to an energetic optimum. In the case of step width, it is costlier to walk with either wider or narrower steps than normally preferred. Wider steps require more mechanical work to redirect the body's motion laterally with each step, but the cost for narrower steps remains unexplained. Here we show that narrow steps are costly because they require the swing leg to be circumducted around the stance leg. Healthy adults (N=8) were tested walking with varying levels of circumduction, induced through lightweight, physical obstructions ("Fins") attached medially to the lower legs, during treadmill walking at fixed speed (1...

This introduction summarizes the main findings of the Supplement 'Social inequalities in health and their determinants' to the European Journal of Public Health. The 16 articles that constitute this supplement use the new ESS (2014) health module data to analyze the distribution of health across European populations. Three main themes run across these articles: documentation of cross-national variation in the magnitude and patterning of health inequalities; assessment of health determinants variation across populations and in their contribution to health inequalities; and the examination of the effects of health outcomes across social groups...

Humans routinely scan their environment for useful information using saccadic eye movements and/or coordinated movements of the eyes and other body segments such the head and the torso. Most previous eye movement studies were conducted with seated subject and showed that single saccades and sequences of saccades (e.g. double-step saccades) made to briefly flashed stimuli were equally accurate and precise. As one can easily appreciate, most gaze shifts performed daily by a given person are not produced from a seated position, but rather from a standing position either as subjects perform an action from an upright stance or as they walk from one place to another...
