Filter by:The objective of this study was to document longitudinal outcomes in persons with traumatic brain injury (TBI) or stroke using the myoelectric upper limb orthosis with powered elbow and grasp in conjunction with motor learning-based therapy using both patient centric performance and patient reported outcome measures. Longitudinal observation allowed the investigators to detect both the initial therapeutic effects as well as the later functional outcomes of orthosis use. The investigators planned to recruit 15 Veterans and non-veterans who had TBI or stroke and upper limb impairment. The study required 29 visits over 22 weeks and was divided into three parts: orthotic fitting, therapy/training (9 weeks), and home use (9 weeks). Therapeutic and functional benefits were evaluated every 2 to 3 weeks over 18 weeks using simple, short clinical tests.
Acquired brain injury (e.g., traumatic brain injury, brain tumour, brain infections) is one of the leading causes of death and disability for children and adolescents. Importantly, injuries affecting the brain in childhood or adolescence appear during a time of development when the brain is particularly vulnerable. Thus, pediatric acquired brain injury does not only impact cognitive functions at the time of injury or onset of disease, but also cognitive functions that are yet to develop. Changes in cognitive function, and in particular executive dysfunction due to acquired brain injury, cause significant real-life disability, yet solid evidence in support of executive functioning interventions for children and adolescents is lacking. In the present study different group-based cognitive rehabilitation interventions will be compared. The aim of the study is to investigate if a group-based "brain training" intervention is able to improve executive function in children and adolescents after acquired brain injury. Efficacy will be assessed immediately after intervention, but also six months after the intervention. The project is in line with international research efforts aimed at establishing more knowledge about how children and adolescents with brain injuries respond to cognitive rehabilitation.
The aim of this research program is to 1) Evaluate potential problems with vision, inner ear-eye reflexes and deficits of processing eye information that occur following TBI; and 2) Evaluate treatment programs for individuals with eye and inner ear problems that persist for greater than 10 days following injury. This study will include 465 youth and young adults (aged 6-30 years old) who sustain a TBI of any severity. An initial evaluative phase using the best available technology to evaluate eye and inner ear function will be performed, and compared with typical tests that are used in the clinic. If symptoms and functional problems remain 10 days after injury, participants will be randomly placed into a treatment group (including eye movement, inner ear-eye reflex and attention exercises as per our pilot studies) or a control group (typical rehabilitation). Success will be measured in terms of return to sport (mild TBI), achievement of goals (moderate and severe TBI) and quality of life. It is expected that this program will inform clinical practice and future research leading to a treatment program in TBI that includes multiple components.
Background: Patients with mild traumatic brain injury can to some extend experience long-term physical, cognitive, social and behavioral deficits, which have serious implications for employment trajectories and financial independence. These deficits have shown to be more pronounced in women. High socio-economic position such as income, level of education and employment status before the accident have shown to affect return to work. But also cohabitation status, ethnicity and health are important factors. Previously studies are typically self-report studies, and are often small and may suffer from selection bias due to patient nonresponse. Aim: The aim of this study is to describe no return to work among patients with mild traumatic brain injury in Denmark and to examine how factors such as age, gender, cohabitation status, socio-economic and pre-injury health factors affect no return to work up to 5 years post-injury. Hypothesis: We hypothesize that most patients with mild traumatic brain injury return to work within work 6 months post-injury, and that patients with mild traumatic brain injury injury receive more social transfer payments compared to the general population. Additionally, we hypothesize that low socio economic position, comorbidities and being single are associated with prolonged no return to work. Methods: The present study is an observational national register-based cohort study with long-term follow up of patients with mild traumatic brain injury from 1st of January 2008 - 31st of December 2012 in Denmark. Patients aged 18-60 years diagnosed with concussion from 1st of January 2003-31st of December 2007 in the national patient register will be included in the study. Data will be retrieved from several national databases, including the DREAM database containing data on social benefits and reimbursements. Primary outcome is no-return to work (nRTW) due to any cause and the following four secondary outcomes are graded and should be regarded as a continuum ranging from health related nRTW, limited nRTW, permanently nRTW and mortality. The results will be published as two separate scientific articles.
This study is part of a larger, multi-centered project done with the collaboration of University Of Victoria. This study holds three separate studies on the mild traumatic brain injured population and the use of perceptual-cognitive training (3D-MOT).
Mechanical ventilation is an important support strategy for critically ill patients. It could improve gas exchange, reduce the work of breathing, and improve patient comfort. However, patient-ventilator asynchrony, which defined as a mismatch between the patient and ventilator may obfuscate these goals. Studies have shown that a high incidence of asynchrony (asynchrony index > 10%) is associated with prolonged mechanical ventilation and ICU length of stay and high mortality. So far, there have been only a few studies on the epidemiology of asynchrony in brain-injured patients. Investigators conduct a prospective observational study among brain-injured patients to determine the prevalence, risk factors and outcomes of patient-ventilator asynchrony. Esophageal pressure monitoring, a surrogate for pleural pressure, combined with airway pressure and flow waveforms is used to detect patient-ventilator asynchrony.
The primary aim of this study is to assess the efficacy of PST for positively impacting distressed military family caregiver's depression and burden levels (secondary outcomes), ultimately enhancing their mental health quality of life (QOL, primary outcome).
Performance Validity Tests (PVTs) are widely used for the detection of sub-optimal effort and malingering in neuropsychological assessments. Threats to their validity however likely to intensify with time (e.g., information available on the web or from legal representatives) and may lead to a decline in their ability to differentiate between malingerers and non-malingerers. Eye movements and response time (RT) are less obvious outcome measures and under less conscious control than more conventional PVT indices (e.g., accuracy). They are therefore promising measures that can aid in detecting malingering when used in conjunction with more conventional PVT indices. The Word Memory Test (WMT) is a widely used PVT in neuropsychological evaluations. As part of the proposed study, TBI patients, chronic pain patients and healthy adults (60 in each group) will be randomly divided to one of two conditions; optimal effort or sub-optimal effort (participants will be asked to play a TBI patient who wishes to present himself as having cognitive deficits or exaggerate existing cognitive deficits). The proposed study will improve the WMT's efficacy in detection of sub-optimal effort in neuropsychological evaluations and therefore protect its validity from future threats. In addition, the proposed study will provide us with better understanding of the effect of TBI on eye movements and RTs in general.
The purpose of this study is to evaluate the feasibility and effects of a cognitive intervention for youth following concussion
End stage renal disease (ESRD) is the last stage (stage 5) of chronic kidney disease (CKD). Abnormalities of cognitive function and high levels of depression or anxiety incidence are characteristic of hemodialysis patients. In this research project, the investigators subject in ESRD patients starting hemodialysis as the carrier.
