A number of preclinical rodent models have been developed in an effort to recapitulate injury mechanisms and identify potential therapeutics for traumatic brain injury (TBI), which is a major cause of death and long-term disability in the United States. However, the lack of restorative treatments for TBI has led to considerable criticism of current preclinical therapeutic development strategies, namely the translatability of widely-used rodent models to human patients. The use of large animal models, such as the pig, with more comparable brain anatomy and physiology to humans may enhance the translational capacity of current preclinical animal models...

Although shoe friction has been widely studied in occupational ergonomics, information was lacking about friction in sport shoes. The purpose of the study was to examine the neuromechanical adaptations to different shoe-surface interface in an aerobic-gym specific movement. Sixteen females performed 10 change of direction movements in two shoe conditions differing by their outsoles (ethyl-vinyl-acetate: EVA and rubber: RB) to ensure significant differences in mechanical coefficients of friction (EVA = 0...

The adaptability of human bipedal locomotion has been studied using split-belt treadmill walking. Most of previous studies utilized experimental protocol under remarkably different split ratios (e.g. 1:2, 1:3, or 1:4). While, there is limited research with regard to adaptive process under the small speed ratios. It is important to know the nature of adaptive process under ratio smaller than 1:2, because systematic evaluation of the gait adaptation under small to moderate split ratios would enable us to examine relative contribution of two forms of adaptation (reactive feedback and predictive feedforward control) on gait adaptation...

Adele Wingrave, Hannah Jarvis
BACKGROUND: Chondrosarcomas account for approximately 20% of bone sarcomas, with the most common site being the lower limb. Hemipelvectomies that involve hindquarter amputation have previously been the treatment of choice for pelvic tumors. However, with advances in chemotherapy, radiotherapy, imaging and surgical techniques more patients are now being treated with limb salvage surgery. The rehabilitation outcomes following an internal hemipelvectomy have not been well identified and there is currently little, if any, gait analysis data on rehabilitation following hemipelvectomy in limb salvage patients...

Background: Implementing an open door policy is a complex intervention comprising changes in therapeutic stance, team processes, and a change from locked to open doors. Recent studies show that it can lead to a reduction of seclusion and forced medication, but the role of the physical change of door status is still unclear. Aims: The aims of this study is to examine the transition from closed to predominantly open doors on a psychiatric intensive care unit (PICU) and its associations with the frequency of seclusion and forced medication...

BACKGROUND: Gait initiation can be performed at a range of speeds. Those with disability tend to use a slower speed compared to those without disability. In assessing the spatiotemporal and kinematic characteristics of gait initiation it is therefore important to consider the effects of speed on outcomes. RESEARCH QUESTION: What is the effect of speed of performance on spatiotemporal and kinematic characteristics of gait initiation? METHODS: Spatiotemporal and kinematic characteristics were measured across a wide range of speeds from very slow to very fast (normalised initiating leg (swing or SW limb) step speed 0...

BACKGROUND: Proximal tibia fractures are one of the most familiar fractures. Surgical approaches are usually needed for anatomical reduction. However, no single treatment method has been widely established as the standard care. Our present study aims to compare the stress and stability of intramedullary nails (IMN) fixation and double locking plate (DLP) fixation in the treatment of extra-articular proximal tibial fractures. METHODS: A three-dimensional (3D) finite element model of the extra-articular proximal tibial fracture, whose 2-cm bone gap began 7 cm from the tibial plateau articular surface, was created fixed by different fixation implants...

INTRODUCTION: It has been widely postulated that structural and functional misalignments of the foot, such as flat foot, may cause mechanical deviations of the lower limb during walking. The aim of this study was to investigate the effect of foot orthoses on lower extremity joint moment asymmetry during the stance phase of walking in children with asymptomatic flexible flat feet. METHODS: Fourteen volunteer male children, clinically diagnosed with flexible flat feet, participated in this study...

Public involvement in disinvestment decision making in health care is widely advocated, and in some cases legally mandated. However, attempts to involve the public in other areas of health policy have been accused of tokenism and manipulation. This paper presents research into the views of local health care leaders in the English National Health Service (NHS) with regards to the involvement of citizens and local communities in disinvestment decision making. The research includes a Q study and follow-up interviews with a sample of health care clinicians and managers in senior roles in the English NHS...

Knee osteoarthritis (KOA) is most common in the medial tibial compartment. We present a novel method to study the effect of gait modifications and lateral wedge insoles (LWIs) on the stresses in the medial tibial cartilage by combining musculoskeletal (MS) modelling with finite element (FE) analysis. Subject's gait was recorded in a gait laboratory, walking normally, with 5° and 10° LWIs, toes inward ('Toe in'), and toes outward ('Toe out wide'). A full lower extremity MRI and a detailed knee MRI were taken...

Solanum glaucophyllum, a toxic plant known for its calcinogenic effects, causes enzootic calcinosis in ruminant and monogastric animals. We describe an outbreak of enzootic calcinosis that occurred in a herd of 110 horses grazing pastureland heavily contaminated with S. glaucophyllum in Buenos Aires province, Argentina. Ten horses developed clinical signs, and 6 horses died. Clinical signs included abnormal gait (stiff-legged action, short strides), stiffness, thoracolumbar kyphosis, reluctance to move, wide stance, chronic weight loss, weakness, recumbency, and difficulty standing...

Stepping on ground can be evoked in human neonates, though it is rather irregular and stereotyped heel-to-toe roll-over pattern is lacking. Such investigations can provide insights into the role of contact- or load-related proprioceptive feedback during early development of locomotion. However, the detailed characteristics of foot placements and their association with motor patterns are still incompletely documented. We elicited stepping in 33 neonates supported on a table. Unilateral limb kinematics, bilateral plantar pressure distribution and EMG activity from up to 11 ipsilateral leg muscles were recorded...

Justin P Waxman, Kevin R Ford, Anh-Dung Nguyen, Jeffrey B Taylor
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 1-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...
