#1
Steven S Taylor, Rosemary A Taylor
As part of a senior leadership class in an undergraduate baccalaureate nursing program in the northeastern United States, we conducted an experiential, theater-based workshop designed to increase student awareness of the micro-dynamics of power and the enactment of status in their day-to-day lives. These exercises allowed student participants to embody status and power and understand it in ways that they did not after simply completing assigned readings. At the conclusion of the workshop the participants were asked to reflect on their status habits and the consequences of these habits in a single hand-written page...

AIMS: Tibiofemoral alignment is important to determine the rate of progression of osteoarthritis and implant survival after total knee arthroplasty (TKA). Normally, surgeons aim for neutral tibiofemoral alignment following TKA, but this has been questioned in recent years. The aim of this study was to evaluate whether varus or valgus alignment indeed leads to increased medial or lateral tibiofemoral forces during static and dynamic weight-bearing activities. PATIENTS AND METHODS: Tibiofemoral contact forces and moments were measured in nine patients with instrumented knee implants...

The idea that antioxidant supplements can prevent or cure many diseases is extremely popular. To study the public understanding of antioxidants on the Web, we searched the term "antioxidants" in http://Google.com and analyzed 200 websites in terms of typology (news, commercial, professional, health portal, no-profit or government organization, scientific journals), disease or biological process mentioned (aging, immunity, neurological disease, diabetes, arthritis, etc.), and stance toward antioxidants, whether neutral, positive, or negative...

Laterally wedged insoles have been shown to be effective for the reduction of the knee adduction moment and other biomechanical variables that are associated with the pathogenesis of knee osteoarthritis. However, inconclusive results such as adverse effects in individual subjects or even no group-wise wedge effects have been presented in different studies and it has been suggested to identify variables that potentially confound the wedge effect. The main objective of this study was the investigation of interaction effects of lateral wedges with walking speed, as different self-selected speeds have mainly been used in previous studies...

INTRODUCTION: A functional assessment of 38 patients after ankle arthrodesis for the evaluation of the necessity of surgeons-specialisation was carried out by means of clinical evaluation and gait analysis after an average follow up of 30 months. METHODS: Scores were used to grade ankle function. Gate analysis was examined to determine the effect of arthrodesis on the ankle in relation to the surgeons' experience. Under conditions of normal daily living, we found significant differences in life quality between patients operated upon by experts in orthopaedic foot and ankle surgery (group A) and patients operated by general orthopaedic surgeons (group B)...

BACKGROUND: Disturbed postural stability in neck pain (NP) is likely due to abnormal cervical afferent function. Several potential causes requires specific diagnostic tests. The neck torsion (head still body rotated) manoeuvre stimulates cervical but not vestibular receptors and identified abnormal cervical afferent input as the cause in patients with NP compared to healthy controls. Comparison between vestibular and NP subjects is now needed. AIMS: To compare individuals with unilateral vestibular loss (UVL), persistent NP and asymptomatic controls...

The mainstream theories and models of the physical sciences, including neuroscience, are all consistent with the principle of causality. Wholly causal explanations make sense of how things go, but are inherently value-neutral, providing no objective basis for true beliefs being better than false beliefs, nor for it being better to intend wisely than foolishly. Dennett (1987) makes a related point in calling the brain a syntactic (procedure-based) engine. He says that you cannot get to a semantic (meaning-based) engine from there...

BACKGROUND CONTEXT: Arthrodesis of the lumbosacral junction continues to be a challenge in pediatric and adult spinal deformity surgery. PURPOSE: To evaluate the biomechanical rigidity of two types of lumbosacral fixation. Our hypothesis was that the use of S2 alar-iliac (S2AI) fixation will result in statistically similar biomechanical fixation as compared with use of an iliac screw with a 95% confidence interval. STUDY SETTING: Controlled biomechanical laboratory METHODS: Ten human cadaveric lumbosacral specimens were separated into two test groups: (1) S2AI (n=5) and (2) iliac screw (n=5)...

Peripheral nerves are fragile and easily damaged, usually resulting in nervous tissue loss, motor and sensory function loss. Advances in neuroscience and engineering have been significantly contributing to bridge the damage nerve and create permissive environment for axonal regrowth across lesions. We have successfully designed two self-assembling peptides by modifying RADA 16-I with two functional motifs IKVAV and RGD. Nanofiber hydrogel formed when combing the two neutral solutions together, defined as RADA 16-Mix that overcomes the main drawback of RADA16-I associated with low pH...

Using a lifting and balancing task, we contrasted two alternative views of planning joint actions: one postulating that joint action involves distinct predictions for self and other, the other postulating that joint action involves coordinated plans between the coactors and reuse of bimanual models. We compared compensatory movements required to keep a tray balanced when 2 participants lifted glasses from each other's trays at the same time (simultaneous joint action) and when they took turns lifting (sequential joint action)...

OBJECTIVES: Malrotation of the femoral component can result in post-operative complications in total knee arthroplasty (TKA), including patellar maltracking. Therefore, we used computational simulation to investigate the influence of femoral malrotation on contact stresses on the polyethylene (PE) insert and on the patellar button as well as on the forces on the collateral ligaments. MATERIALS AND METHODS: Validated finite element (FE) models, for internal and external malrotations from 0° to 10° with regard to the neutral position, were developed to evaluate the effect of malrotation on the femoral component in TKA...

#13
Cédrick T Bonnet, Sébastien Szaffarczyk
In studies of postural control, a control task is often used to understand significant effects obtained with experimental manipulations. This task should be the easiest task and (therefore) engage the lowest behavioral variability and cognitive workload. Since 1983, the stationary-gaze task is considered as the most relevant control task. Instead, the authors expected that free looking at small targets (white paper or images; visual angle: 12°) could be an easier task. To verify this assumption, 16 young individuals performed stationary-gaze, white-panel, and free-viewing 12° tasks in steady and relaxed stances...

RANDOMIZED CONTROLLED TRIAL
Oliver Ludwig, Jens Kelm, Michael Fröhlich
BACKGROUND: Peroneus longus acts as a foot evertor and pronator, thus ensuring stability of the talocrural joint by curbing inversion movement of the rearfoot. Increased activation of the peroneus longus muscle in the stance phase could have a stabilising effect on the ankle joint. This study aimed to determine whether the activity of the peroneus longus muscle could be increased by the targeted use of a specially formed lateral pressure element in a customised orthopaedic insole. METHODS: This was a laboratory-based study that utilised a randomised crossover design...

REVIEW
Nicole Perret, Giuseppe Longo
Reductionism is the dominant stance of biology. According to this perspective, biological phenomena have to fit with physical explanations. Some biologists thought that the introduction of the idea of program was a sound way to overcome both physicalism and reductionism. We argue instead that the introduction of information theory into biology did not liberate biology from reductionism. We argue that the adoption of information in biology is an erroneous transposition from a specific mathematical domain to one where it does not belong...

The main purpose of this study was to examine the effects of affective auditory stimuli on balance control during static stance. Twelve female and 12 male participants were recruited. Each participant completed four upright standing trials including three auditory stimuli trials and one baseline trial (ie no auditory stimuli). The three auditory stimuli trials corresponded to the pleasant, neutral and unpleasant sound conditions. Center of pressure (COP) measures were used to quantify balance control performance...

BACKGROUND: The subtalar joint position during static stance is a crucial determinant of the peak plantar pressures and forms ideal reference point for any intervention in foot-related problems for leprosy-affected patients. OBJECTIVES: The study pursued the hypothesis through a three-dimensional model that stress will be minimal in the distal joints of the foot when the subtalar joint is in neutral static stance position. STUDY DESIGN: Finite element model...

Change in sagittal spinal curvature from the neutral upright stance is an important measure of the heaviness and correctness of backpack use. As current recommendations, with respect to spinal profile, of backpack load thresholds were based on the significant curvature change in individual spinal region only, this study investigated the most critical backpack load by assessing simultaneously the spinal curvature changes along the whole spine. A motion analysis system was used to measure the curvature changes in cervical, upper thoracic, lower thoracic and lumbar regions with backpack load at 0, 5, 10, 15 and 20% of body weight...
