Ethics of life-sustaining treatment in locked-in syndrome : A Chinese survey / Yifan Yan in Annals of physical and rehabilitation medicine, Vol. 63, n°6 (November 20)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 63, n°6 (November 20) . - p. 483-487 Titre : Ethics of life-sustaining treatment in locked-in syndrome : A Chinese survey Type de document : texte imprimé Auteurs : Yifan Yan ; Athena Demertzi ; Yinyan Xia ; Jing Wang ; Nantu Hu ; Zhiliang Zhang ; Haibo Di ; Steven Laureys Année de publication : 2020 Article en page(s) : p. 483-487 Note générale : doi.org/10.1016/j.rehab.2019.09.011 Langues : Anglais (eng) Mots-clés : End-of-life  Locked-in syndrome  Survey  Attitude  Unresponsive wakefulness syndrome Résumé : Background Locked-in syndrome (LIS) characterizes individuals who have experienced pontine lesions, who have limited motor output but with preserved cognitive abilities. Despite their severe physical impairment, individuals with LIS self-profess a higher quality of life than generally expected. Such third-person expectations about LIS are shaped by personal and cultural factors in western countries. Objective We sought to investigate whether such opinions are further influenced by the cultural background in East Asia. We surveyed attitudes about the ethics of life-sustaining treatment in LIS in a cohort of medical and non-medical Chinese participants. Results The final study sample included 1545 respondents: medical professionals (n = 597, 39%), neurologists (n = 303, 20%), legal professionals (n = 276, 18%) and other professionals (n = 369, 24%), including 180 family members of individuals with LIS. Most of the participants (70%), especially neurologists, thought that life-sustaining treatment could not be stopped in individuals with LIS. It might be unnecessary to withdraw life-sustaining treatment, because the condition involved is not terminal and irreversible, and physical treatment can be beneficial for the patient. A significant proportion (59%) of respondents would like to be kept alive if they were in that condition; however, older people thought the opposite. Families experience the stress of caring for individuals with LIS. The mean (SD) quality of life score for relatives was 0.73 (2.889) (on a −5, +5 scale), which was significantly lower than that of non-relatives, 1.75 (1.969) (P < 0.001). Conclusions Differences in opinions about end of life in LIS are affected by personal characteristics. The current survey did not identify a dissociation between personal preferences and general opinions, potentially because of a social uniformity in China where individualism is less pronounced. Future open-ended surveys could identify specific needs of caregivers so that strategic interventions to reduce ethical debasement are designed.

Mental imagery for brain-computer interface control and communication in non-responsive individuals / Zulay R. Lugo in Annals of physical and rehabilitation medicine, Vol. 63, n°1 (Janvier 2020)

Public ISBD [article]  inAnnals of physical and rehabilitation medicine > Vol. 63, n°1 (Janvier 2020) . - p. 21-27 Titre : Mental imagery for brain-computer interface control and communication in non-responsive individuals Type de document : texte imprimé Auteurs : Zulay R. Lugo ; Christoph Pokorny ; Frédéric Pellas ; Quentin Noirhomme ; Steven Laureys ; Gernot Müller-Putz ; Andrea Kübler Année de publication : 2020 Article en page(s) : p. 21-27 Note générale : doi.org/10.1016/j.rehab.2019.02.005 Langues : Anglais (eng) Mots-clés : Brain-computer interface  Locked-in syndrome  User-centered design  Disorders of consciousness Résumé : Background People who survive severe brain damage may eventually develop a prolonged consciousness disorder. Others can regain full consciousness but remain unable to speak or move because of the severity of the lesions, as for those with locked-in syndrome (LIS). Brain-computer interface techniques can be useful to disentangle these states by detecting neurophysiological correlates of conscious processing of information to enable communication with these individuals after the diagnosis. Objective The goal of our study was to evaluate with a user-centered design approach the usability of a mental imagery task to detect signs of voluntary information processing and enabling communication in a group of severely disabled individuals. Methods Five individuals with LIS participated in the study. Participants were instructed to imagine hand, arm or feet movements during electroencephalography (EEG) to detect patterns of event-related synchronization/desynchronization associated with each task. After the user-centered design, usability was evaluated (i.e., efficiency, effectiveness and satisfaction). Results Two participants achieved significant levels of accuracy in 2 different tasks. The associated workload and levels of satisfaction perceived by the users were moderate and were mainly related to the time demand of the task. Conclusion Results 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.
