Excitatory Prefrontal Weak Current Stimulation in Vegetative Patients
Disorder of ConsciousnessMMN9 moreIn response to "conscious" EEG findings related to detectable cognitive function that reliably denote awareness in vegetative state patients, in the current study, we will assess the covert conscious EEG activity (as well as standard clinical overt measures) and neuroplasctic propensity (i.e., changes in EEG spectral power synchronization values following tDCS intervention) in vegetative-state patients receiving repetitive transcranial direct current stimulation (tDCS) treatment over frontal motor areas for a period of two weeks. In support of this approach, a recent tDCS study with vegetative and minimally conscious patients implied that a twenty minutes anodal stimulation (i.e., excitatory stimulation) to the left dorsolateral prefrontal cortex (DLPFC) significantly increased CRS-R scores versus sham (placebo: non-active stimulation) stimulation condition. It was noted that this tDCS effect was more pronounced in minimally conscious state patients versus vegetative state patients excluding effects of chronicity or etiology. Thus, the investigators in this study suggested that tDCS could be effective in improving cognitive recovery in severely brain-injured patients. However, their findings would benefit neural activation correlates that could support their conclusion regarding the effectiveness of this type of non-invasive intervention in promoting neurocognitive recovery. Most importantly, tDCS is safe for use in humans, has no adverse effects, is considered the most non-invasive transcranial stimulation method because it uses extremely weak currents (0.5 to 2 mA), and, is known to only temporarily shift the neuron's membrane potential towards excitation/inhibition. In regard to the method's potential to induce functional recovery in vegetative state patients, recent clinical studies indicate that tDCS could counteract the negative effects of brain damage by influencing neurophysiological mechanisms, and is likely to contribute to the "formation of functionally meaningful connections and the maintenance of existing pathways" .
Improving New Learning and Memory in School Aged Children
Traumatic Brain InjuryThe currently proposed study addresses a critical need in the clinical care of school-aged children with TBI through the modification of an existing, proven efficacious treatment protocol for learning and memory deficits in persons with moderate to severe TBI, the modified Story Memory Technique (mSMT), as well as the conduct of a pilot double blind, placebo-controlled, RCT of this new pediatric adaptation of the mSMT. Over a decade of research and development conducted at our center has demonstrated the mSMT to be effective for improving new learning and memory in adults with TBI, across three realms of functioning: objective behavior, brain functioning and everyday life. This convincing data provides Class I evidence supporting the efficacy of the mSMT for improving new learning and memory in adults with TBI. Clinical applications around the world have equally attested to its utility in the clinical care of adults with TBI. This highlights the tremendous potential of the mSMT to vastly improve the everyday lives and educational successes of children and adoles-cents living with TBI and the resultant learning and memory deficits. The currently proposed pilot work will begin to document that efficacy. The results of this study therefore have the potential to change clinical practice, inform policy, and improve the lives of children and adolescents living with TBI.
Treatment of Spontaneous Hyperventilation With Remifentanil in Traumatic Brain Injury Patients
HyperventilationTraumatic Brain InjurySpontaneous hyperventilation is common in severe traumatic brain injury patients and correlates closely with poor outcomes. How to treat this pathological condition remain unsolved. Remifentanil is a frequently used short-acting opioid, has the potent side-effect of dose-dependent respiratory inhibition. Specifically, it prolongs the expiratory time only and does not influence the respiratory drive. Among the safety range, the investigators will determine an ideal dose of remifentanil to maintain PaCO2 between 35 to 45 mmHg. The investigators will monitor the cerebral blood flow of the middle cerebral artery and the internal carotid artery to validate cerebral perfusion improvement.
Virtual Environment Rehabilitation for Patients With Motor Neglect Trial
Complex Regional Pain SyndromesFibromyalgia5 moreMotor neglect describes a loss of function without a loss of strength, reflexes or sensation. Motor neglect has been described in patients with traumatic brain injury, stroke and chronic pain conditions, e.g. complex regional pain syndrome. These conditions affect hundreds of thousands of patients in the UK each year and motor neglect is a significant obstacle in their rehabilitation towards a good outcome. By focussing on improving motor neglect, outcomes including function and quality of life for these groups of patients may significantly improve. Motor neglect is potentially reversible. Rehabilitation using repetition, feedback and motivation are beneficial for optimal outcome. Current protocols use face-to-face physical therapies which can not optimise intensity due to a lack of resources. Furthermore, engagement with exercise is recognised to be poor, in part, due to a lack of attention. Innovative technologies may well improve engagement. Furthermore, telemedicine, or remote delivery of healthcare, offer opportunities in resource management, which can be delivered through the use of such innovative technologies. Virtual reality systems have been designed and utilised in rehabilitation in various conditions, e.g post-stroke, cerebral palsy and Parkinson's disease. Studies demonstrate improved function in both upper and lower limbs. Potentially more effective treatments for motor neglect utilising such technology are therefore available but need more formal evaluation. This protocol describes a Phase II randomised controlled trial for both in-patients and out-patients requiring rehabilitation with motor neglect from neurological causes (stroke, traumatic brain injury) and chronic pain conditions (Complex Regional Pain Syndromes, chronic low back pain and referred leg pain (sciatica)). The intervention will be a novel interactive virtual reality system using established technology and tailored software used in conjunction with a treadmill. The control group will be the same screen showing random static images whilst on the treadmill. Rehabilitation for each group will be offered in 3-4 sessions per week for 2 weeks. Each session will last about 30 minutes supervised by a physiotherapist. Follow-up will be by questionnaire at weeks 2, 6 and 12 and by face-to-face consultation at weeks 2 and 12.
The Effects of MBSR on Patients With TBI and Chronic Insomnia
Chronic InsomniaTBI (Traumatic Brain Injury)To evaluate the effects of Mindfulness Based Stress Reduction (MBSR) as an adjunct to usual clinical care for treatment of stress and chronic insomnia for patients with mild to moderate traumatic brain injury (MTBI). MBSR is a standardized protocol of meditation and yoga that has been studied extensively in other populations, however the effects of MBSR have not yet been well studied in the proposed population of service members with a Traumatic Brain Injury (TBI) who are experiencing insomnia.
Prevalence of Trephined Syndrome After Decompressive Craniectomy
Trephined SyndromeSinking Skin Flap Syndrome5 moreDecompressive craniectomy is frequently used to treat increased intracranial pressure or an intracranial mass effect. Trephined Syndrome describes a neurological deterioration, which is attributed to a large craniectomy. The symptomatology is varied but includes headache, aggravation of a hemisyndrome or cognitive disorders, often has an orthostatic component and improves or disappears with cranioplasty. The incidence of Trephined Syndrome has been reported between 7% and 26%. However, it might be underestimated if the course of cognitive functions before and after cranioplasty were insufficiently documented.
Rehabilitation of Visual Function After Brain Injury
StrokeIschemic3 moreIn Denmark, about 120,000 people suffer from brain damage, of whom approx. 75,000 with brain damage after stroke. Serious and often lasting vision impairments affect 20% to 35% of people after stroke. Vision is the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Vision impairments after brain damage inhibits rehabilitation and enhances other invalidating effects. Reduced vision results in impaired balance, increased risk of serious falls, increased support needs, reduced quality of life, and impaired ability to perform activities of daily living. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is very limited. Hence, brain-impaired persons with visual impairment will most likely experience chronically impaired vision already 4 weeks after brain injury and the need for visual compensatory rehabilitation is substantial. Neuro Vision Technology (NVT) is an supervised training course where people with visual impairments are trained in compensatory techniques using special equipment. Through the NVT process, the individual's vision problems are carefully investigated and personal data is used to organize individual training sessions that practice the individual in coping with situations that cause problems in everyday life. The purpose of this study is to investigate whether rehabilitation with NVT can cause significant and lasting improvement in functional capacity in persons with chronic visual impairments after brain injury. Improving eyesight is expected to increase both physical and mental functioning, thus improving the quality of life. Participants included in the project will be investigated in terms of both visual and mental functions, including quality of life, cognition and depression. Such an investigation has not been performed previously and can have a significant impact on vision rehabilitation both nationally and internationally.
Effects of an Interdisciplinary Fitness and Social Engagement Intervention
TBI (Traumatic Brain Injury)This study will evaluate feasibility and preliminary effectiveness of a 10-week interdisciplinary and multimodal intervention that utilizes patient education, group discussion, and supervised exercise for Veterans with a history of traumatic brain injury (TBI). Primary outcomes include physical activity (PA), sleep quality, and community integration.
Partial Blocks of Rectus Femoris and Soleus With Botulinum Toxin Type A (Xeomin®) to Improve Gait...
Hemiparesis After StrokeTraumatic Brain InjuryThe most common motor deficiency after stroke or traumatic brain injury is hemiparesis. Most hemiparetic patients recover walking, but rarely with a speed permitting easy ambulation outdoors with family or friends. One of the mechanisms of gait impairment in hemiparesis is insufficient active hip flexion during swing phase, which leads to insufficient ground clearing at swing phase, with associated gait slowness and risks of fall. The main hypothesis behind the present study is that insufficient hip flexion during hemiparetic gait is partly due to overactivity of rectus femoris. Focal treatment of lower limb muscle overactivity using botulinum toxin has not been demonstrated to increase walking speed in hemiparesis as yet. However, most studies have focused distally, on improving foot dorsiflexion only. The purpose of this study is to compare the effects of botulinum toxin injection and placebo in rectus femoris (RF) + plantar flexors versus plantar flexors only.
