Accurately predicting the occupant kinematics is critical to better understand the injury mechanisms during an automotive crash event. The objectives of this study were to develop and validate a finite element (FE) model of the human body integrated with an active muscle model called Total HUman Model for Safety (THUMS) version 5, which has the body size of the 50th percentile American adult male (AM50). This model is characterized by being able to generate a force owing to muscle tone and to predict the occupant response during an automotive crash event...

Advances in brain-computer interface research have recently empowered the development of wearable sensors to record mobile electroencephalography (EEG) as an unobtrusive and easy-to-use alternative to conventional scalp EEG. One such mobile solution is to record EEG from the ear canal, which has been validated for auditory steady state responses and discrete event related potentials (ERPs). However, it is still under discussion where to place recording and reference electrodes to capture best responses to auditory stimuli...

Our ability to automatically adapt our walking pattern to the demands of our environment is central to maintaining a steady gait. Accordingly, a large effort is being made to extend and integrate this adaptability to lower-limb prostheses. To date, the main focus of this research has been on short term adaptation, such as in response to a terrain transition or a sudden change in the environment. However, long term adaptation and underlying sensorimotor learning processes are critical to optimizing walking patterns and predictively changing our gait when faced with continued perturbations...

Predicting location of fracture in human bones has been a keen area of research for the past few decades. A variety of tests for hardness, deformation and strain field measurement have been conducted in the past; but considered insufficient due to various limitations. Researchers therefore have proposed further studies due to inaccuracies in measurement methods, testing machines and experimental errors. Advancement and availability of hardware, measuring instrumentation and testing machines can now provide remedies to these limitations...

Most multiple sclerosis (MS) patients eventually suffer from mobility impairment, and thus it is critical that walking disability in MS be accurately assessed. The six-minute walk test (6MWT), a reliable MS measure, is traditionally used to determine the distance covered in six minutes using a standard protocol. With the availability of body sensor networks (BSNs), researchers are interested in leveraging BSN data for finding new gait assessment anchors for improved separability performance. Further, current methods for gait assessments are insufficient since assessments are absolute, performed by comparing outcomes to the statistical norms established from diverse patient data despite natural inter-patient variability...

A wide range of assistive technologies have been developed to support the elderly population with the goal of promoting independent living. The adoption of these technology based solutions is, however, critical to their overarching success. In our previous research we addressed the significance of modelling user adoption to reminding technologies based on a range of physical, environmental and social factors. In our current work we build upon our initial modeling through considering a wider range of computational approaches and identify a reduced set of relevant features that can aid the medical professionals to make an informed choice of whether to recommend the technology or not...

This study proposes a novel stair-climbing wheelchair based on lever propulsion control using the human upper body. Wheelchairs are widely used as supporting locomotion devices for people with acquired lower limb disabilities. However, steps and stairs are critical obstacles to locomotion, which restrict their activities when using wheelchairs. Previous research focused on power-assisted, stair-climbing wheelchairs, which were large and heavy due to its large actuators and mechanisms. In the previous research, we proposed a wheelchair with lever propulsion mechanism and presented its feasibility of climbing up the stairs...

Adverse drug reactions (ADRs) detection is critical to avoid malpractices yet challenging due to its uncertainty in pre-marketing review and the underreporting in post-marketing surveillance. To conquer this predicament, social media based ADRs detection methods have been proposed recently. However, existing researches are mostly co-occurrence based methods and face several issues, in particularly, leaving out the rare ADRs and unable to distinguish irrelevant ADRs. In this work, we introduce a constrained information entropy (CIE) method to solve these problems...

Knowledge of a cause-and-effect relationship between different physiological systems is helpful in predicting their performance under perturbations, such as orthostatic challenge. The causal coupling between representative signals of the cardiovascular and postural systems under orthostatic challenge remains unknown. Understanding the causal relationship between these two systems is critical, as their interplay is vital to maintain stable upright posture of the human body during quiet standing. In this research, convergent cross mapping (CCM) method was applied to study the causal relationship between the cardiovascular and postural systems previously shown to have coherent activity during quiet standing...

Consistent, robust performance is critical for the utility and user-acceptance of neurally-controlled powered upper limb prostheses. We preliminarily evaluated the performance consistency of an electromyography (EMG)-driven controller based on a two degree-of-freedom musculoskeletal hand model, whose simplified structure is more practical for real-time prosthesis control than existing, complex models. Parameters of four virtual muscles were computed by numerical optimization from an able-bodied subject's kinematic and EMG data collected during wrist and metacarpophalangeal (MCP) flexion/extension movements...

Prescription opioid pain reliever (OPR) misuse and diversion is an important and growing public health problem in the United States that is responsible for significant morbidity and mortality. Emergency physicians are among the top prescribers of OPRs, yet the relative contribution of emergency department (ED) OPR prescriptions to the overall opioid abuse epidemic remains unclear. This study critically reviews seven peer-reviewed studies that specifically identified the ED as a source of OPRs. Of the OPRs prescribed in the ED, approximately 10% are associated with indicators of inappropriate prescribing, and approximately 42% may ultimately be misused; of the OPRs that are diverted, approximately 10% originate from an ED prescription...

Despite a significant growth in the number older former family carers, they remain largely invisible in carer-related research and literature. To begin to address this deficit, a four-stage literature review was conducted to identify existing knowledge about older former carers. Narrative synthesis of the findings yielded five themes - the concept of 'older former carer', the legacies of caring, influences on the legacies of caring, conceptualising post-caring and support services for older former carers. Critical analysis of these findings suggests that existing evidence has a number of strengths...

Nudging as a means of influencing human behaviour has received increasing attention by policy makers, including those in the field of public health. Nudges are generally understood as specific aspects of a choice architecture that make certain behaviours more likely to occur without mandating them through binding rules, and without relying on economic incentives. Following the example of the United States and Great Britain, the German government has established a working group tasked with advising the federal government on the use of nudging and other behavioural interventions in policy making...

Yoga has become an increasingly common health practice among U.S. adults over the past decade. With this growth in popularity, yoga-related print media have been criticized for shifting away from yoga's traditional philosophies and promoting a thin, lean ideal physique representing the "yoga body." The purpose of this study was to (a) analyze the presence and content of advertisements over the 40-year publication history of Yoga Journal magazine and (b) explore female advertisement models' socio-demographic and appearance-related attributes over time...

PURPOSE OF REVIEW: The global burden of disease in skin and soft tissue lesions is enormous. Many chronic, poorly healing lesions get treated with antibiotics despite the lack of evidence for long-term antibiotics. There is a global antibiotic resistance crisis driven largely by inappropriate use of large volumes of antibiotics. One solution is to reduce the selection pressure on bacteria by reducing the volume of antibiotic use in medicine, agriculture and the environment. There are few novel antimicrobials...

Observational treatment studies provide a valuable alternative to RCTs but are often criticized due to potential self-selection biases. Studies comparing those who do and do not participate in research on eating disorder treatment are scarce, but necessary to evaluate the impact of self-selection bias on outcomes. All consecutive underweight adult first admissions (N = 392) to an integrated inpatient (IP)-partial hospital (PH) behavioral specialty program were invited to participate in a longitudinal study of eating disorder treatment...

OBJECTIVE: Most children in the United States are evaluated in general emergency departments (ED), which are staffed by practitioners who care for both adults and children and may have limited pediatric resources. The application of telemedicine in pediatrics is growing and has been shown to be effective in outpatient as well as critical care settings. Telemedicine has the potential to address disparities in access to pediatric emergency care. The objective of this study was to explore experiences of general ED providers with telemedicine and their perception about a potential video telemedicine program with pediatric ED providers...
