Filter by:This study evaluates the feasibility of an experimental protocol that combines advanced multi-modal imaging of the brain with clinical and behavioural scales to characterise the neural, behavioural, and clinical effects of transcranial direct current stimulation (tDCS) for rehabilitation in PDOC
Non-invasive brain stimulations techniques have recently shown promising results in patients with disorders of consciousness. Notably, a case reported improvement of level of consciousness using transcutaneous auricular vagal nerve stimulation in a patient in unresponsive wakefulness syndrome. Here we aim to assess the effects of transcutaneous auricular vagal nerve stimulation on post-coma patients with disorders of consciousness in a first randomized controlled trial. To measure these effects, behavioral (Coma recovery scale revised - CRS-R -primary outcome) and neuro-electrophysiological (electroencephalography - EEG - secondary outcome) data will be recorded in severely brain-injured patients with DOC.
The aim of this study is to assess the utility of advanced magnetic resonance imaging (MRI) and electroencephalographic (EEG) technologies for predicting functional outcomes in patients with severe traumatic brain injury (TBI).

There is practical evidence but no scientific investigations that persons with severe disorders of consciousness can profit from animal-assisted therapy regarding their level of awareness. The aim of this study is to investigate the effect of animal-assisted therapy on brain activity of inpatients at REHAB Basel with severe disorders of consciousness. To do so, the frontal brain activity of 20 the inpatients at REHAB Basel in a minimally conscious state is investigated via near-infrared spectroscopy (NIRS). Moreover, 20 healthy participants are included as control subjects.
Severe brain injuries lead to disorders of consciousness after coma. During this awakening period, detection of arousal is critical to the adaptation of medical strategy, but global paralysis, including facial expression, make the clinical assessment very difficult. Emotional facial expressions are a significant part of this clinical assessment. They are both a landmark of the internal state of the patient (comfort versus discomfort) and a landmark of the relational level with his environment. Visible emotional facial expression is a large temporal phenomenon lasting a couple of seconds, while a microexpression is barely noticeable and very brief. These micro expressions are usually produced when one tried to voluntary hide emotional expressions. In this study, we hypothesize that some patients awakening from coma could still produce microexpression before being able to produce visible emotional facial expressions. This ability to produce micro-expression could be an early landmark of relational awakening in severe brain lesions.
