Active clinical trials for "Brain Injuries"

Stiff knee gait is a common gait dysfunction following acquired brain injury. This gait deviation is characterized by reduced knee flexion during swing phase of the gait cycle and adversely impacts safe foot clearance. Stiff knee gait is an inefficient gait pattern and slows walking speed, limiting one's ability to adapt walking to community mobility demands. Fall risk is increased with this gait problem due to low or ineffective foot clearance. Common compensatory strategies are employed, such as circumduction, hip hiking or vaulting, during ambulation. The purpose of this study is to examine both the immediate (one month post-injection) and longer-term (4 months post-injection) effects of botulinum toxin injections to the rectus femoris (RF) on gait function in persons with brain injury. This study is clinically important to help inform rehabilitation professionals regarding treatment decisions for management of inefficient and often unsafe stiff knee gait problems following brain injury. Research Questions: Is there a statistically significant difference in mean peak knee flexion between the experimental and control group? Is there a statistically significant difference in mean peak knee velocity during the preswing and initial swing phases of gait between the experimental and control group? Is there a statistically significant difference in gait function (based on 6-Minute Walk time and temporal distance measures) between the experimental and control group?

The purpose of this study is to improve the ability to diagnose problems after mild traumatic brain injury (MTBI) and to test a drug that may improve the outcome from these injuries. Of the more than 1.5 million people who experience a traumatic brain injury (TBI) each year in the United States, as many as 75% sustain a mild TBI which can cause long-term or permanent impairments/disabilities in a significant proportion of patients. In addition, traumatic brain injury has become a signature injury of the wars in Iraq and Afghanistan. For people with these injuries, it is difficult to determine whether symptoms are due to the head injury or another condition, such as Post-traumatic Stress Disorder. In this project, there are 3 observational studies that involve testing of mental functions and behavior, imaging of the brain with special x-ray procedures, and blood samples to look at glandular function, which may be affected by head injury. A fourth study is a test of a drug, atorvastatin, which may provide protection for injured brain cells and improve outcome. By collecting and analyzing the information from these tests, it will be possible to make the process of diagnosing mild TBI or post traumatic stress disorder (PTSD) more precise, and also to see if atorvastatin is a helpful drug for patients with MTBI.

Severe traumatic brain injury is associated with an increased production of free radicals causing brain damage. First line treatment of these patients aims to maintain cerebral perfusion and includes deep anaesthesia. Propofol has recently shown anti oxidant properties that need to be confirmed when used in these patients. The main objective of this study is to evaluate the effect of propofol compared to midazolam on intra cerebral oxidative stress following severe traumatic brain injury.

The purpose of this study is to evaluate the efficacy of early conversion tracheostomy from endotracheal intubation (ET) to percutaneous, dilatational tracheostomy (PDT) in traumatic brain-injured patients requiring prolonged mechanical ventilation.

Induction of hypothermia to < 35˚C by < 2.5 hours after severe traumatic brain injury, reaching 33˚C by 4 hours after injury and maintained for 48 hours in patients aged 16-45 will result in an increased number of patients with good outcomes at six months after injury compared to patients randomized to normothermia.

The aim of this study is to increase the effectiveness of clinical monitoring of patients with acute cerebral insufficiency by improving the discriminative ability of the FOUR scale. To study the sensitivity and specificity of the FOUR scale as a clinimetric of chronic disorders of consciousness.

This is a Phase 1, multi-center, randomized, double-blind, placebo-controlled, multiple-ascending- dose trial to evaluate the safety, tolerability, immunogenicity, and pharmacokinetics of intravenous PNT001 in hospitalized patients with traumatic brain injury.

Viral pandemics, such as HIV and SARS-Cov-V1, have shown that they can lead to acute and / or delayed neurological complications. At the actual context of the pandemic Coronavirus disease 2019 (COVID-19), neurological manifestations seem to be confirmed since in 85% of COVID-19 patients, present neurological symptoms, including anosmia, ageusia, periorbital pain, dizziness, fatigue, even moderate headache, moderate memory and/or behavioral disorders. However, these neurological manifestations are not well studied and their radiological features are not well described. It is therefore important to assess these potential neurological complications in COVID-19 patients. To the investigator knowledge, there is no previous study in the literature describing spectral brain changes in COVID + patients. Thus, the goal of this work is to describe the radiological semiology using MRI and particularly Magnetic Resonance Spectroscopic (MRS) biomarkers in the evaluation of acute and / or delayed brain damage in COVID + patients presenting a neurological manifestations that are initially related to the cranial nerves damage.

This study investigates whether an individually designed environment can support and improve the quality of daytime resting periods in in-hospital neurorehabilitation of patients suffering severe acquired brain injury. The effect of a individually optimized resting environment will be tested against a standard resting environment.

Standard neuropsychological evaluations after severe TBI (traumatic brain injury) often minimizes the executive deficits, these latter are known to seriously impair return to work. Therefore, we developed an ecological organization and problem-solving test in a vocational setting called the TEM-PRO. The test consists of 4 activities of variable complexity, collection and redaction of information and demands to follow well defined rules.
