Stability of a chronic implanted brain-computer interface in late-stage amyotrophic lateral sclerosis

ObjectiveWe investigated the long-term functional stability and home use of a fully implanted electrocorticography (ECoG)-based brain-computer interface (BCI) for communication by an individual with late-stage Amyotrophic Lateral Sclerosis (ALS).MethodsData recorded from the cortical surface of the motor and prefrontal cortex with an implanted brain-computer interface device was evaluated for 36 months after implantation of the system in an individual with late-stage ALS. In addition, electrode impedance and BCI control accuracy were assessed. Key measures included frequency of use of the system for communication, user and system performance, and electrical signal characteristics.ResultsUser performance was high consistently over the three years. Power in the high frequency band, used for the control signal, declined slowly in the motor cortex, but control over the signal remained unaffected by time. Impedance increased until month 5, and then remained constant. Frequency of home use increased steadily, indicating adoption of the system by the user.ConclusionsThe implanted brain-computer interface proves to be robust in an individual with late-stage ALS, given stable performance and control signal for over 36 months.SignificanceThese findings are relevant for the future of implantable brain-computer interfaces along with other brain-sensing technologies, such as responsive neurostimulation.     

Failure of communication: a patient’s story

The first author, a patient who underwent elective caesarean section and felt pain necessitating conversion to general anaesthesia, describes the experience with particular reference to the perceived poor communication between her and her anaesthetist. This extended from the preoperative visit to the information provided to her general practitioner after discharge. She makes several suggestions which would have made her experience, and those of other patients in similar circumstances, less traumatic. The second author, who had no involvement in events and works in a different Trust, comments upon the events from the perspective of an obstetric anaesthetist.     

Clinicians’ accounts of communication with patients in end-of-life care contexts: A systematic review

ObjectiveCommunication between patients and end-of-life care providers requires sensitivity given the context and complexity involved. This systematic review uses a narrative approach to synthesise clinicians’ understandings of communication in end-of-life care.MethodsA systematic, narrative synthesis approach was adopted given the heterogeneity across the 83 included studies. The review was registered prospectively on PROSPERO (ID: CRD42019125155). Medline was searched for all articles catalogued with the MeSH terms “palliative care,” “terminal care” or “end-of-life care,” and “communication”. Articles were assessed for quality using a modified JQI-QARI tool.ResultsThe findings highlight the centrality and complexity of communication in end-of-life care. The challenges identified by clinicians in relation to such communication include the development of skills necessary, complexity of interpersonal interactions, and ways in which organisational factors impact upon communication. Clinicians are also aware of the need to develop strategies for interdisciplinary teams to improve communication.ConclusionTraining needs for effective communication in end-of-life contexts are not currently being met.Practice ImplicationsClinicians need more training to address the lack of skills to overcome interactional difficulties. Attention is also needed to address issues in the organisational contexts in which such communication occurs.     

Training parents to implement communication interventions for children with autism spectrum disorders (ASD): A systematic review

This review identifies procedures used to train parents to implement communication interventions to children with autism spectrum disorders. Systematic search procedures identified 11 studies that met predetermined inclusion criteria. Across studies, 60 parents were trained to implement Pivotal Response Training, Enhanced Milieu Teaching, Natural Language Paradigm, or Early Start Denver Model. The mean time spent training parents was 17 hours. Training procedures used most often included: (a) verbal instruction and/or instruction manuals, (b) in vivo practice, (c) role playing, (d) modeling by trainer, and (e) reviewing videos of intervention sessions. Improvements in parent ability to implement intervention and child communication were ubiquitous. However, a paucity of studies in which baseline parent behavior was measured, coupled with the absence of studies evaluating individual training procedures, precludes definitive statements regarding the most effective and efficient approach to parent training and, therefore, warrant future research.
