Filter by:This study aims to explore autonomic cardiovascular regulation, through measures of heart rate variability (HRV), during different passive and active activities in patients with severe acquired brain injury and a low conscious state. Data from active rehabilitation will be compared with passive periods of rest as well as nightly variance during a continuous 5-day period.
This study aims at comparing the effects of transcranial direct current stimulation and transcranial pulsed current stimulation on neurophysiological outcomes on patients with disorders of consciousness. This study also aims to evaluate the effects of these techniques on patients' level of consciousness.
In this multicentric double-blind sham controlled study, the investigators plan to assess the effects of 20 sessions of tDCS on long-term behavioral recovery in patients with disorders of consciousness. Neurophysiological outcomes (EEG) will also be collected. This research will 1) determine whether long-term behavioral recovery can be promoted with tDCS and 2) generate knowledge regarding the impact of tDCS on neurophysiological outcome (i.e., EEG) in severely brain injured patients. The investigators will compare the effects of active and sham tDCS on behavioral assessments and quantitative EEG in patients with severe brain injury and its potential application in rehabilitation.
The purpose of this study is to validate Russian version of Coma Recovery Scale - Revised and to assess its psychometric properties.
Altered mental status (AMS) is common in older patients. However there is a lack of standardization in the definition and documentation of this compliant. Different perception of AMS can cause negative impact on interpretation and obtaining scientific data. Although definition of AMS is so complicated, clinical documentation can be detected in these patients with AMS.
The purpose of this study is to assess the effects on upper limb spasticity of soft splints worn during three weeks three hours a day by patients with stroke or disorders of consciousness.
Clinical examinations are difficult to discriminate between vegetative state and minimally conscious state. the diagnostic and prognostic usefulness of neuroimaging methods has not been established in a clinical setting. we will do a forward study of PET imaging in disorders of consciousness patients, and validate with clinical assessments with the coma recovery Scale-Revised(CRS-R).
The research contains two parts. Part 1: To explore whether EEG responses to zolpidem can assess consciousness circuit integrity and predict the evolution of consciousness in patients with prolonged disorders of consciousness; Part 2: To explore if quantitative EEG reactivity might predict the prognosis of disorders of consciousness.
In this study, the core body temperature of 7 disorders of consciousness ( DOC ) patients were measured every 2 hour for 168 h .
Progress in resuscitation has increased the chances of survival after anoxic or traumatic brain injury. More and more patients with severe cerebral damages are resuscitated but upon awakening from coma, some patients remain in a state which cannot be qualified as conscious and is now known as an unresponsive wakefulness syndrome (UWS; formerly known as vegetative state). This condition can be transitory and evolve towards recovery, or remain chronic and lasting for years. To improve the diagnosis of patients with disorders of consciousness, recent advances in brain imaging have led to the development of new methods of detecting awareness. In the absence of overt behavioral responses from these patients, imaging-based diagnostic methods have been first used to assess whether some cerebral areas were preserved in UWS patients and showed an activation of the primary sensory cortices in some UWS patients, whether it occurs at the auditory, visual or somatosensory level. Unavoidable technical and ethical issues are raised for clinicians before responding to such requests: 1. Is it technically possible to generalize neuroimaging protocols to all healthcare institutions? 2. Is it ethically acceptable to propose neuroimaging protocols without an accurate estimation of their psychological impact on families and caregivers? The present study aims to understand and anticipate the technical and ethical issues related to an evaluation of consciousness with functional neuroimaging. How the evaluation of awareness in a patient affects the caregivers and family members will be investigated. By using qualitative research hopes and expectations will be clarified through the experiences of families, clinicians and nurses faced to this situation. Will be included in this research professional caregivers and persons closely related to UWS patients: - Family members or close circle visiting the patients on a regular basis - Referring clinicians - Nurses in charge of the patients' care This prospective study uses qualitative, interview-based, research. Two key-moments are explored in succession to examine the impact of a neuroimaging evaluation of consciousness in institutionalized UWS patients: - interviews of professional caregivers and families about their hopes concerning the evaluation of consciousness of UWS patients, - interviews of professional caregivers and families about the impact of evaluating consciousness on their beliefs
