Mental imagery for brain-computer interface control and communication in non-responsive individuals
ConclusionResults showed lack of effectiveness of the task to detect voluntary brain activity and thus detect consciousness or communicate with non-responsive individuals. The application must be modified to be sufficiently satisfying for the intended end-users and suggestions are made in this regard. (Source: Annals of Physical and Rehabilitation Medicine)

Locked-In Syndrome: a Challenge to Standard Accounts of Selfhood and Personhood?
AbstractA point made repeatedly over the last few years is that the Locked-in Syndrome (LIS) offers unique real-life material for revisiting and challenging certain ingrained philosophical assumptions about the nature of personhood and personal identity. Indeed, the claim has been made that a closer study of LIS will call into question some of the traditional conceptions of personhood that primarily highlight the significance of consciousness, self-consciousness and autonomy and suggest the need for a more interpersonal account of the person. I am skeptical about these claims and will in the following argue that the theore...

More than our Body: Minimal and Enactive Selfhood in Global Paralysis
AbstractThis paper looks to phenomenology and enactive cognition in order to shed light on the self and sense of self of patients with locked-in syndrome. It critically discusses the concept of the minimal self, both in its phenomenological and ontological dimension. Ontologically speaking, the self is considered to be equal to a person ’s sensorimotor embodiment. This bodily self also grounds the minimal sense of self as being a distinct experiential subject. The view from the minimal bodily self presupposes that sociality comes after the self, or that in other words, the essence of self remains independent of our socia...

The role of the interdisciplinary team in subacute rehabilitation for central pontine myelinolysis.
CONCLUSION: This report illustrates the critical role of a patient-centered and goal-driven interdisciplinary team approach in the rehabilitation of persons with central pontine myelinolysis. Implications for rehabilitation Central Pontine Myelinolysis can result in profound acute disability, including incomplete locked-in syndrome. Interdisciplinary post-acute rehabilitation is beneficial in maximizing functional recovery and minimizing secondary complications for individuals with Central Pontine Myelinolysis. Ongoing clinical assessment and team collaboration contribute to progressive and comprehensive plan of care devel...

La domotique en santé, un espoir pour l’autonomie des patients
ConclusionSimon Vlieghe, Domoticien en Santé, vous propose de vous pencher sur la question de l’importance de la domotique et de sa plus-value sur le bien-être des patients, leur autonomie, mais également l’allègement de la charge de travail pour vos aides-soignants en apportant la possibilité aux patients, jusqu’ici considérée comme très dépendant, de pouvoir enfin faire des actions eux-mêmes.

Long-term, non-invasive brain stimulation for locked-in syndrome
Background& significance: Locked-in syndrome is a very serious condition with desperate quality of life due to profound paralysis, and there is no effective treatment other than rehabilitation. Repetitive transcranial magnetic stimulation (rTMS) seems to be benefit in motor recovery of stroke patients. We explored the benefit and feasibility of rTMS in locked-in syndrome.

Discomfort as a Catalyst: An Ethical Analysis of Donation after Cardiac Death in a Patient with Locked-In Syndrome.
This article shows how, in determining whether or not to talk to the patient or family during end-of-life decision making, the weight assigned to the various ethical concerns in the case-the patient's condition, the decision to be made, and the family's agreement or disagreement regarding the patient's wishes-can "swing the pendulum" of ethical analysis in different ways. The comfort of the patient must be accorded the highest priority, as well as the needs of the patient's family. This case study highlights the nuanced contextual factors necessary to guide a treatment team's approach to DCD for a patient with uncertain de...

Phenomenology of the Locked-In Syndrome: an Overview and Some Suggestions
AbstractThere is no systematic knowledge about how individuals with Locked-in Syndrome (LIS) experience their situation. A phenomenology of LIS, in the sense of a description of subjective experience as lived by the ill persons themselves, does not yet exist as an organized endeavor. The present article takes a step in that direction by reviewing various materials and making some suggestions. First-person narratives provide the most important sources, but very few have been discussed. LIS barely appears in bioethics and neuroethics. Research on Quality of Life (QOL) provides relevant information, one questionnaire study ex...

Sensors, Vol. 18, Pages 2989: Classification of Overt and Covert Speech for Near-Infrared Spectroscopy-Based Brain Computer Interface
In this study, it was hypothesized that changes in local hemodynamic activity, due to the activation of Broca’s area during overt/covert speech, can be harnessed to create an intuitive Brain Computer Interface based on Near-Infrared Spectroscopy (NIRS). A 12-channel square template was used to cover inferior frontal gyrus and changes in hemoglobin concentration corresponding to six aloud (overtly) and six silently (covertly) spoken words were collected from eight healthy participants. An unsupervised feature extraction algorithm was implemented with an optimized support vector machine for classification. For ...

When is "brainstem death" brain death? The case for ancillary testing in primary infratentorial brain lesion.
Abstract
The widely accepted concept of brain death (BD) comprises the demonstration of irreversible coma in combination with the loss of brainstem reflexes and irreversible apnea. In some countries the combined clinical finding of coma, apnea, and loss of all tested brainstem reflexes ("brainstem death") is sufficient for diagnosing BD irrespective of the primary location of brain lesion. The present article aims to substantiate the need for ancillary testing in patients with primary infratentorial brain lesions. Anatomically, the "brainstem-death" syndrome can theoretically occur without relevant lesion ...

Language-Model Assisted and Icon-Based Communication Through a Brain–Computer Interface With Different Presentation Paradigms
Augmentative and alternative communication (AAC) is typically used by people with severe speech and physical disabilities and is one of the main application areas for the brain–computer interface (BCI) technology. The target population includes people with cerebral palsy, amyotrophic lateral sclerosis, and locked-in syndrome. Word-based AAC systems are mainly faster than letter-based counterparts and are usually supplemented by icons to aid the users. Those icon-based AAC systems that use binary signaling methods such as single click can convert into a single-input BCI system such as event-related potential (ERP) de...

Effect of Exercise on Physical Recovery of People with Locked-In Syndrome after Stroke: What Do We Know from the Current Evidence? A Systematic Review
Conclusion: Studies indicate a positive trend of effect of exercise for physical recovery of people with LIS after stroke including the improvement of muscle strength, tone, walking ability, and activity in daily living. Mixed physical exercises were used. The effects were not significant. No adverse event has been reported. The quality of the existing evidence is relatively low since the papers were either case series or case studies. Further studies are needed on exercise types and dosages for better prescriptions for people with LIS after stroke. This may help to extend their lives with better control of the complicatio...
