Feasibility of Two New Software Modules for the Rehabilitation of Patients With Neuromuscular Upper...
StrokeParkinson Disease2 moreIntroduction: In the recent past, medical training systems using virtual reality (VR) have been introduced to neurorehabilitation to train motor function deficits in patients. The usage of VR-based training systems is based on the evidence of neuroplasticity, which is responsible for recovery of patients suffering from motor dysfunction. Such systems are increasingly used to encourage purposeful limb movements in a VR environment and its efficacy has been found comparable with conventional therapeutic intervention. VR training systems, e.g. the YouGrabber® (YG), will increasingly also be used at home. Therefore, it is essential to integrate valid and reliable assessment tools to monitor the recovery process. Objectives: The aim of the clinical study is to evaluate the usability, feasibility and validity of the digital version of the ActionResearchArmTest (d-ARAT) using the YG system as a platform. Additionally, the feasibility and usability of the implementation of two rehabilitation measures that only recently became integral part of neurorehabilitation, e.g. Action Observation (AO) and Motor Imagery (MI), into the YG training software will be evaluated. Patients & methods: This observational study is designed as a single-arm trial for testing the assessment software including pre- to post rehabilitation comparison of a training involving AO and MI. Therefore, 75 adult patients with Parkinson's disease, MS, Stroke, traumatic brain injury or Guillain-Barré syndrome will be included. 30 out of the 75 patients will take part in the 4-week training on the enhanced VR-based system with a total of 16 training sessions of 45 min each. Primary outcomes will be the score on the System Usability Scale (SUS) and the ARAT as well as the d-ARAT scores. Secondary outcomes will be hand dexterity (Box-and-Block Test), upper limb activities of daily living (CAHAI) and quality of life (EQ-5D-5L). Hypothesis: The study was designed to evaluate the d-ARAT and the training software modules for the YG system. Currently AO and MI specific tasks are being integrated and the ARAT subscales will be implemented on the basis of the redesigned glove equipped with new sensors. The results are expected to give recommendations for necessary modifications. They might also contribute knowledge concerning the application of AO and MI tasks within VR training.
Mild Traumatic Brain Injury and the Risk for Traumatic Intracranial Hemorrhage
Traumatic Intracranial HemorrhageBrain InjuriesManagement of traumatic brain injuries causes significant efforts on emergency departments (ED) and overall health care. Patients on antithrombotic treatment with even minor trauma to the head, although without significant clinical findings, represent special challenges because the risk of traumatic intracranial hemorrhage (tICH) with these agents. The aim of this study was to compare the prevalence of tICH in patients on various pre-injury antithrombotic treatment exposed to minor Traumatic Brain injuries (mTBI) in Sundsvall with untreated patients. Secondary aim was to explore different risk factors for tICH. Data from medical records and radiology registry with mTBI in Sundsvall hospital between 2018-2020 in Sundsvall identified 2044 patients. Demographic data, pre-injury medications with antithrombotic treatment, state of consciousness at admission and the results of CT-scans of brain was investigated.
SSVEP Evaluation of Brain Function
Mild Traumatic Brain InjuryThe investigational device used in this clinical investigation, the Nurochek Headset, is a portable electroencephalogram (EEG) headset which delivers a visual stimulus and measures a VEP. The visual stimulus is delivered to the subjects' eyes via light-emitting diodes, and the EEG measures the user's visual-evoked potential. This headset communicates with an application on a smartphone which processes the signals and transmits them to a secure cloud server for analysis and storage of the data. The primary objective of this clinical investigation was to evaluate the performance of the investigation device (NCII) against clinical diagnosis and SCAT 5, in the accurate detection of mild traumatic brain injury (mTBI). The primary endpoint outlined for this study was set at the collection of 100 valid investigational device readings from individuals with concussion The aim of this study was to collect data from 100 readings from individuals with concussion. It was estimate that approximately 10-20% of baselined players would suffer a concussion during the season. There it was estimated there would be a need to baseline 500-1000 individuals in order to achieve the number of concussions required. The initial assumption was that sites would provide players pre-season and make players available for testing post-concussion. In practice, some sites provided player data only post-concussion event (such as medical clinics). Participants were required from sporting clubs, medical clinicals and schools.
Identification and Comprehension of Focused Stress in a Sentence Among Adults Who Suffered Traumatic...
Focused StressResearches that focus on the perception of prosodic elements among adult who suffered traumatic brain injury (TBI), focus on their ability to decipher intonation in order to understand an additional meaning of a sentence. According to these researches, adults who suffer from TBI, with no signs of Aphasia, have difficulty perceiving and deciphering intonation (Marquardt et al., 2001; Angeleri et al., 2008). The current research asks to broaden the knowledge in this domain by examining the ability of adults with TBI to understand an additional prosodic element - focused stress. The ability to identify and understand focused stress in a sentence requires different abilities. First, a psychoacoustic ability in order to detect the stressed word. Second, an ability to understand the lexical grammatical meaning of the word as it negates other possible meanings (for example, in the sentence "I'm eating a red apple" the stressed word negated the option of a different color). Third, an understanding of the stressed word as it creates a different pragmatic/social meaning (for example, in the sentence "mom, I asked for red, yellow and green candy" the role of the stressed word is to mark the candy that the addressee didn't get). The aim of the study is to assess the ability of adults who had experienced TBI to grasp and understand the meaning of focused stress in the different contexts that were described above. An additional aim is to examine if differences in speech and cognitive abilities can describe some of the variation in the results. Thirty adults between the ages of 18-50 years will take part in this study, fifteen adults who had experienced moderate to severe TBI (0.5-3 years post injury) and fifteen healthy adults. Each participant with TBI will be matched to a healthy adult by gender, age, education and social-economic status. All of the participants will be Hebrew native speakers, with no learning disability, no neurological injury, proper speech abilities and no hearing impairment. The participants will undergo seven different tests in three different meetings (60 minute each), in a quiet room at Sheba - Academic Medical Center Hospital. The tests will include different cognitive and language examinations. The main test of the study will be The Hebrew Focused Stress Test (HFST). The HFST includes three subtests. The first subtest requires identification of the stressed word in a sentence based on psychoacoustic abilities alone. The second and the third subtests require understanding the meaning of focused stress in different contexts - lexical grammatical and pragmatic/social. The test includes forty eight recorded sentences. In each sentence one word is stressed. The participants will be asked to listen to the recordings and answer a closed question regarding the stressed word.
iNtrAcranial PreSsurE in Intensive Care (ICU) (SynapseICU)
Traumatic Brain InjurySubarachnoid Hemorrhage1 moreIntracranial pressure (ICP) monitoring is the most common neuromonitoring modality used in neurocritical care units (NCCU) around the world. Uncertainties remain around intracranial pressure monitoring both in traumatic and non-traumatic brain injury, and variation in clinical practice of intracranial pressure monitoring exists between neurocritical care units. The objectives of the study will explore intracranial pressure monitoring variation in practice to prioritise uncertainties in the clinical management of critical care patients with acute brain injury and support further collaborative hypotheses-based prospective studies.

Risk Factors Predicting Prognosis and Outcome of Elderly Patients With Isolated Traumatic Brain...
Brain InjuriesAlthough several prognostic models have been developed to predict outcome for patients with severe traumatic brain injury (TBI), currently no study describes the impact of respiratory failure during Emergency Department treatment on mortality in a population of elderly patients. The purpose of the present study was to evaluate factors predicting poor outcome with special emphasis on the impact of respiratory failure on mortality in elderly patients with isolated severe TBI. All elderly patients (age ≥ 65 years) with isolated severe head injury, admitted to this Level I trauma center, during a period of 16 years (from January 1992 to December 2008) were identified from the trauma registry. Stepwise logistic regression analysis was used to identify risk factors for a poor prognosis and outcome. The logistic regression found the following variables influencing the mortality: respiratory failure (p<0.0005; OR: 9.369), pupillary response (p<0.0212, OR: 3.393) and ISS score (p<0.0001, OR:1.179). A significant (p<0.0001) increased risk of death was also found for patients with a midline shift >15 mm. The present study predicts a strong correlation between respiratory failure, pathological pupillary response, a higher ISS and substantial midline shift with poor outcomes in elderly patients sustaining an isolated severe TBI.
