Well-adapted motor actions require intact and well-integrated information from all of the sensory systems, specifically the visual, vestibular, and somatosensory systems, including proprioception. Proprioception is involved in the sensorimotor control by providing the central nervous system with an updated body schema of the biomechanical and spatial properties of the body parts. With regard to the cervical spine, proprioceptive information from joint and muscle mechanoreceptors is integrated with vestibular and visual feedback to control head position, head orientation, and whole body posture...

This paper presents the results of two cognitive load studies comparing three augmented reality display technologies: spatial augmented reality, the optical see-through Microsoft HoloLens, and the video see-through Samsung Gear VR. In particular, the two experiments focused on isolating the cognitive load cost of receiving instructions for a button-pressing procedural task. The studies employed a self-assessment cognitive load methodology, as well as an additional dual-task cognitive load methodology. The results showed that spatial augmented reality led to increased performance and reduced cognitive load...

Correction of Class II malocclusion by distalization of maxillary molars with intraoral appliances is a non-extraction treatment approach, which has been described as an alternative to Head Gear. From the past few years, the procedures have undergone rectification to achieve treatment objective more precisely. This has been made possible by a better understanding of bone physiology, tooth movement, biomechanics and newer biomaterials. Nowadays newer distalizing appliances, like the Jones Jig, Lokar distalizer and Carrière distalizer, have been developed which have compact designs and cause minimal discomfort to the patient...

Pressure injury prevention is required in all health care environments. Respiratory technology includes invasive and noninvasive positive pressure ventilation methods of support and life-saving equipment. Pressure injury can occur from tracheostomy tubes and their securement devices, or use of noninvasive positive pressure ventilation interfaces or the head gear. Methods instituted to decrease hospital-acquired pressure injury related to noninvasive positive pressure ventilation and tracheostomy securement devices are discussed...

BACKGROUND: Energy-based surgical devices, including electrotome, the Harmonic scalpel, and LigaSure, have been widely applied in thyroid surgery, although a comparison of their safety and efficacy has not been reported yet. In this study, we investigated the feasibility of using hemostatic energy-based surgical devices during thyroid surgery in a canine model. METHODS: Twenty-four beagle dogs were randomly divided into the following groups: electrotome (30 kW), electrotome (15 kW), the Harmonic scalpel (output level 3), and LigaSure (middle gear)...

Background Recreational sledging (tobogganing) is a very popular winter sport in Alpine regions. Ascending and sledging down on the same track, however, might be associated with a certain risk of injury. Therefore, the aim of this study was to gather data on the causes of accidents and potential risk factors during recreational sledging. Methods Adults indulging in recreational sledging were interviewed between March 2013 and March 2015 at six public sledging tracks in the environs of the city of Innsbruck (Tyrol, Austria) on demographics, skill level, sledging frequency, risk-taking behavior, use of protective gear, type of sledge used, previous sledging-related injuries, injured body parts and causes of accidents...

- Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease caused by repetitive head injuries like those seen in sports such as boxing, American football and soccer.- The clinical features of CTE are a range of cognitive, psychiatric and motor symptoms, and histopathology involves deposits of hyperphosphorylated tau protein and the presence of TAR DNA-binding protein (TDP-43) with relatively little beta-amyloid.- CTE is difficult to differentiate clinically from Alzheimer's disease, frontotemporal dementia and psychiatric disorders because of the major symptom overlap between these conditions...

The current study investigates whether repetitive subconcussive impacts cause changes in plasma S100β levels, and also tests the associations between S100β changes and frequency/magnitude of impacts sustained. This prospective study of 22 Division-I collegiate football players included baseline and pre-season practices (one helmet-only and four full-gear). Blood samples were obtained and assessed for S100β levels at baseline and pre- to post-practices; symptom scores were assessed at each time-point. An accelerometer-embedded mouthguard was employed to measure the number of impacts (hits), peak linear acceleration (PLA), and peak rotational acceleration (PRA)...

Respiratory viruses are recognized as serious causes of morbidity and mortality in lower respiratory tract infections in patients. Isothermal amplification assays are increasingly used in their detection because of their rapidity, simplicity and cost-effectiveness, when compared to traditional molecular diagnostic methods. However, systematic assessment of these assays in the clinical settings is rarely reported. MEDLINE (Pubmed) searches were done analysing subject headings and words in the abstract related to isothermal amplification assay and virus...

BACKGROUND: Patients often, but not always, present with features that allow easy differentiation between traumatic brain injury and a stroke. Early diagnosis and appropriate treatment are crucial for a good outcome in both. Millions of people worldwide climb coconut and other trees without any protective gear. We present a case of a coconut tree climber found unconscious after a fall, initially misdiagnosed as a traumatic brain injury but later proven to be a hemorrhagic stroke. We discuss how to prevent such incidents and why that deserves more attention...

Herein, we analyze the energy parameters of stones of various weights and shapes shot from a sling and based on this data evaluate its traumatic potential. Four police officers proficient in the use of a sling participated in the trials. The following projectile types, shot using an overhead technique at a target 100m away were: round steel balls of different sizes and weights (24mm, 57g; 32mm, 135g; 38mm, 227g); different shaped stones weighing 100-150g and 150-200g and a golf ball (47g). Our data indicated that projectiles shot from unconventional weapons such as a sling, have serious traumatic potential for unprotected individuals and can cause blunt trauma of moderate to critical severity such as fractures of the trunk, limb, and facial skull bone, depending on the weight and shape of the projectile and the distance from the source of danger...

AIM: To analyze all windsurfing and kitesurfing (kiteboarding) injuries presented at our coastal hospital over a 2-year period. METHODS: Twenty-five windsurfers (21 male; aged 31 ± 8 years) and 32 kitesurfers (23 male; aged 29 ± 11 years) presented at our hospital during the 2-year study period. Various injury data were recorded, including transport to hospital and treatment. After a median follow-up of 16 mo (range, 7-33 mo), 18 windsurfers (72%) and 26 kitesurfers (81%) completed questionnaires on the trauma mechanisms, the use of protective gear, time spent on windsurfing or kitesurfing, time to return to sports, additional injuries, and chronic disability...

Traditional 1D anthropometric data have been the primary source of information used by ergonomists for the dimensioning of head and facial gear. Although these data are simple to use and understand, they only provide univariate measures of key dimensions. 3D anthropometric data, however, describe the complete shape characteristics of the head surface, but are complicated to interpret due to the abundance of information they contain. Consequently, current headform standards based on 1D measurements may not adequately represent the actual head shape variations of the intended user groups...
