Eye-movements are the only directly observable behavioural signals that are highly correlated with actions at the task level, and proactive of body movements and thus reflect action intentions. Moreover, eye movements are preserved in many movement disorders leading to paralysis (or amputees) from stroke, spinal cord injury, Parkinson's disease, multiple sclerosis, and muscular dystrophy among others. Despite this benefit, eye tracking is not widely used as control interface for robotic interfaces in movement impaired patients due to poor human-robot interfaces...

One of the main challenges in the use of a powered lower limb exoskeleton (LLE) is to ensure that balance is maintained throughout the operation of the device. Since no control strategy has yet been implemented that prevents falls in the case of a loss of balance, head or other serious injuries may occur during independent use of LLEs in the event of a fall. These safety concerns limit LLEs in the community to supervised use only. Using the backward fall as a model, we used optimization techniques to develop safe fall control strategies in order to avoid head impact and mitigate the impact velocity of the hips...

BACKGROUND: Pathologies of the long head of biceps tendon (LHB) can cause anterior shoulder pain. Surgical treatment includes tenotomy and tenodesis (TD), however TD causes fewer cosmetic deformities and less cramping of the biceps muscle. To date, numerous techniques for TD have been described but the "gold standard" has not yet been established. OBJECTIVES: The purpose of this study is to evaluate the functional and cosmetic outcome following subpectoral biceps TD with an interference screw and a cortical-button (STLHB-IC) after 1 year...

Concussion has been linked to the presence of injurious strains in the brain tissues. Research investigating severe brain injury has reported that strains in the brain may be affected by two parameters: magnitude of the acceleration, and duration of that acceleration. However, little is known how this relationship changes in terms of creating risk for brain injury for magnitudes and durations of acceleration common in sporting environments. This has particular implications for the understanding and prevention of concussive risk of injury in sporting environments...

INTRODUCTION: Information about injuries and its differences in Cliff Diving (CD) and Splash Diving (SD) are unknown. It was the aim to analyse (1) injury rates, patterns and causes; (2) differences (in injuries) between both disciplines; and to (3) identify targets for future injury prevention interventions. METHODS: From April to November 2013, 81 cliff and 51 splash divers were prospectively surveyed with an encrypted, monthly e-mail-based questionnaire. RESULTS: During a total of 7857h diving with an average diving height of 13 (±7)m, an overall injury rate of 7...

INTRODUCTION: Higher transfusion ratios of plasma to packed red blood cells (PRBC) and platelets (PLT) to PRBC have been shown to be associated with decreased mortality in major trauma patients. However, little is known about the effect of transfusion ratios on mortality in patients with isolated severe traumatic brain injury (TBI). The aim of this study was to investigate the effect of transfusion ratios on mortality in patients with isolated severe blunt TBI. We hypothesized that higher transfusion ratios of plasma to PRBC and PLT to PRBC are associated with a lower mortality rate in these patients...

OBJECTIVES: Cognitive defects such as learning and memory impairment are amongst the most repetitious sequelae after sever and moderate traumatic brain injury (TBI). It was suggested that ellagic acid (EA), an innate phenol product, display neuroprotective properties against oxidative and inflammatory damages after brain injury. The object of the current study was therapeutic properties of EA on blood-brain barrier (BBB) interruption and elevated content of TNF-α in brain tissue followed by neurologic aftereffects, cognitive and brain electrophysiology deficits as outcomes of diffuse TBI in rat...

INTRODUCTION: Each year in the United States, approximately 1.7 million people sustain a traumatic brain injury (TBI). Of these TBI events, about 75 percent are characterized as being mild brain injuries. Immediately following TBI, a secondary brain damage persists for hours, days, and even months. Previously, detection of neuronal and glial biomarkers have proven to be useful to predict neurological outcomes. Here, we hypothesized that creatine kinase, brain (CKBB) is a sensitive biomarker for acute secondary brain injury in professional boxers...

BACKGROUND: Injury to the distal musculotendinous T junction (DMTJ) of the biceps femoris is a distinct clinical entity that behaves differently from other hamstring injuries due to its complex, multicomponent anatomy and dual innervation. Injury in this region demonstrates a particularly high rate of recurrence, even with prolonged rehabilitation times. PURPOSE: To describe the anatomy of the DMTJ of the biceps femoris and analyze the injury patterns seen on magnetic resonance imaging (MRI) to aid prognosis and rehabilitation and minimize the risk of recurrence...

Recurrent laryngeal nerve (RLN) injury in neonates, a complication of head and neck surgeries, leads to increased aspiration risk and swallowing dysfunction. The severity of resulting sequelae range from morbidity, such as aspiration pneumonia, to mortality from infection and failure to thrive. The timing of airway protective events including laryngeal vestibule closure (LVC) is implicated in aspiration. We unilaterally transected the RLN in an infant pig model to observe changes in the timing of swallowing kinematics with lesion and aspiration...

BACKGROUND: Mild traumatic brain injuries (mTBI) are an increasing health concern due to persistent behavioral and neurological effects. To better understand these effects, researchers frequently rely on animal injury models. Existing models, however, may not adequately reproduce the mechanism of injury as it occurs in humans. NEW METHOD: Our new model for inducing mTBI in rodents entails acceleration of the animal toward a stationary impact zone to produce rapid rotational movement of the head...

INTRODUCTION: Transient osteoporosis of the hip (TOH) is a self-limiting disorder characterized by bone marrow edema at the femoral head and neck. Patients report pain as moderate or severe at onset; pain gradually subsides at about six months (range four to 12 months). Differential diagnosis of the early stages of osteonecrosis of the femoral head (ONFH) is sometimes difficult. Because hyperbaric oxygen (HBO₂) therapy is effective for reduction of edema in soft tissue injury and early stages of ONFH, we hypothesized that HBO₂ could be effective in TOH for accelerated recovery...

INTRODUCTION: Recently, two large prospective clinical trials developed and validated prediction rules for children at very low risk for clinically important traumatic brain injuries (ciTBI) or abdominal injury for whom CT is unnecessary. Specific criteria/guidelines were identified which if met would obviate the need for CT scanning. The purpose of this study was to assess compliance at a level one pediatric center with these guidelines as a tool for quality improvement. METHODS: Records of children admitted to our pediatric trauma center one year before and two years after publication of head (Kuppermann '09) and abdominal trauma (Holmes '13) CT imaging guidelines were reviewed...

The delayed diagnosis of adrenal insufficiency is relatively common because its symptoms are non-specific. One of the causes of adrenal insufficiency is isolated adrenocorticotropic hormone deficiency (IAD), which is sometimes caused by traumatic brain injury. Indeed, severe head trauma is considered to contribute to the incidence of this disease. However, the relationship between milder head trauma-such as chronic subdural hematoma - and the occurrence of hormonal deficiency is uncertain. We herein report the case of a 79-year-old man with IAD who presented with leg edema and pain in his extremities following a recent history of chronic subdural hematoma...

BACKGROUND: Antidepressant use has been associated with an increased risk of falling, but no studies have been conducted on whether antidepressant use is associated with an increased risk of head injuries which often result from falling among older persons. The objective of this study was to investigate the risk of head and brain injuries associated with antidepressant use among community-dwelling persons with Alzheimer's disease. METHODS: A matched cohort study was conducted by comparing new antidepressant users (n = 10,910) with two matched nonusers (n = 21,820) in the MEDALZ study cohort...

Providencia rettgeri (P. rettgeri) is an ubiquitous organism but is seldom associated with human disease. We report the isolation of P. rettgeri from the urine sample of a 39-year-old male patient on prolonged Foley's catheterisation following a severe head injury. Identification of this organism was done by Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry (MALDI-TOF) based systems. P. rettgeri is an emerging pathogen among long term catheterised patients. It reflects its ability to form biofilm on the surface of the indwelling catheter as well as the inherent urease producing property of the pathogen in question as a possible mechanism of pathogenesis...
