Experiment protocol for human–robot interaction studies with seniors with mild cognitive impairments

While assistive robotics (AR) have shown promise in supporting seniors with daily life activities and psycho-social development, evaluation of AR systems presents novel challenges. From a technical point of view, reproducing HRI experiments has been problematic due to the lack of protocols, standardization and benchmarking tools, which ultimately impairs the evaluation of previous experiments. On the other hand, working with seniors with cognitive decline presents a major design challenge for researchers, since communication skills, state of mind and attention of participants are compromised. To address these challenges, this paper presents practical recommendations and a protocol for conducting HRI experiments with seniors with mild cognitive decline (MCI)

Did my brain implant make me do it? Questions raised by DBS regarding psychological continuity, responsibility for action and mental competence

Contains fulltext : 99253.pdf (publisher's version ) (Open Access)Deep brain stimulation (DBS) is a wellaccepted treatment for movement disorders and is currently explored as a treatment option for various neurological and psychiatric disorders. Several case studies suggest that DBS may, in some patients, influence mental states critical to personality to such an extent that it affects an individual’s personal identity, i.e. the experience of psychological continuity, of persisting through time as the same person. Without questioning the usefulness of DBS as a treatment option for various serious and treatment refractory conditions, the potential of disruptions of psychological continuity raises a number of ethical and legal questions. An important question is that of legal responsibility if DBS induced changes in a patient’s personality result in damage caused by undesirable or even deviant behavior. Disruptions in psychological continuity can in some cases also have an effect on an individual’s mental competence. This capacity is necessary in order to obtain informed consent to start, continue or stop treatment, and it is therefore not only important from an ethical point of view but also has legal consequences. Taking the existing literature and the Dutch legal system as a starting point, the present paper discusses the implications of DBS induced disruptions in psychological continuity for a patient’s responsibility for action and competence of decision and raises a number of questions that need further research.13 p

REFINE (Reducing Falls in in-patient elderly) a randomised controlled trial

Background: Falls in hospitals are common, resulting in injury and anxiety to patients, and large costs to NHS organisations. More than half of all in-patient falls in elderly people in acute care settings occur at the bedside, during transfers or whilst getting up to go to the toilet. In the majority of cases these falls are unwitnessed. There is insufficient evidence underpinning the effectiveness of interventions to guide clinical staff regarding the reduction of falls in the elderly inpatient. New patient monitoring technologies have the potential to offer advances in falls prevention. Bedside sensor equipment can alert staff, not in the immediate vicinity, to a potential problem and avert a fall. However no studies utilizing this assistive technology have demonstrated a significant reduction in falls rates in a randomised controlled trial setting. Methods/Design: The research design is an individual patient randomised controlled trial of bedside chair and bed pressure sensors, incorporating a radio-paging alerting mode to alert staff to patients rising from their bed or chair, across five acute elderly care wards in Nottingham University Hospitals NHS Trust. Participants will be randomised to bedside chair and bed sensors or to usual care (without the use of sensors). The primary outcome is the number of bedside in-patient falls. Discussion: The REFINE study is the first randomised controlled trial of bedside pressure sensors in elderly inpatients in an acute NHS Trust. We will assess whether falls can be successfully and cost effectively reduced using this technology, and report on its acceptability to both patients and staff
