Background: The management of pain is particularly challenging in patients with moderate to severe dementia owing to the loss of communication ability or underlying causes such as behavioral symptoms. It is often associated with health care professionals' frustration and feeling of helplessness. The present study determined a framework and examined the feasibility of an innovative intervention using the PARO® robot for the management of acute pain in dementia. Method: A mixed-methods research design combining qualitative (five focus groups) and quantitative (questionnaire survey) approaches was used to define the intervention framework. We recruited 57 health care professionals from various medical and paramedical specialties (eg, nursing auxiliaries, nurses, physicians, psychologists) and with expertise in gerontology. The feasibility of the intervention was subsequently assessed with 12 patients suffering from dementia in painful situations to validate the procedure. Results: Four main issues have been addressed: 1) the identification of a core group of painful situations associated with care (washing, dressing/change, transfer/mobilization), currently considered as inefficiently managed; 2) the selection of an appropriate assessment methodology including criteria and tools for pain evaluation; 3) the definition of health professionals' training needs and organizational requirements for their implementation; and 4) the perceived usefulness of a robot-assisted intervention for the management of pain in dementia in daily practice. The feasibility study showed that the predefined intervention framework was applicable and acceptable for the majority of professionals and patients. Conclusion: A consistent and feasible intervention framework for the management of painful situations associated with care in dementia using the PARO robot was defined. Understanding of professionals' needs, opinions and perceived obstacles regarding the intervention was a useful step in the preparation of the forthcoming clinical trial.

Purpose: Misplacing or losing personal belongings is a concern of everyday life among people of all ages. Older adults with cognitive impairment are significantly more affected by this problem. It is a source of frustration, anxiety, interpersonal conflict and disability in this population. Informal caregivers are greatly impacted by this problem, which compels them to spend a lot of time searching for misplaced items and comforting the person. Assistive technology could thus be of great benefit in this area. However, existing item locator devices do not appear to meet the needs of older adults with cognitive disorders. The TROUVE project aims to conceive and assess an innovative item locator device that effectively addresses their needs, capacities, and goals. Procedure: The project team conducted a co-design process involving relevant stakeholders (persons with cognitive impairment, informal and formal caregivers, researchers, industry representatives, ethical bodies) using user-tests, focus groups, interviews, and questionnaires. The project plan involved three phases: (1) analysis of end-users' needs, (2) definition of system requirements and iterative prototype development, and (3) prototype assessment. Findings: The analysis of end users' needs and the evaluation of existing item locator devices provided us with details about the items which are the most frequently lost or misplaced by older adults at home and their coping strategies to manage these situations. The analysis of usability problems observed throughout the assessment of existing devices allowed the definition of the system requirements. Prototype assessment showed that spatialized sound can be used to help these users find missing items, and that an item locator device can be part of a more comprehensive assistive and rehabilitation system such as a robot. Conclusions: An item locator that relies on sensory information (spatialized sound) rather than on conceptual reasoning (“the item is located to your left 4 meters away”) appears to be an interesting solution to address the problem of misplacing personal items in elderly with cognitive impairment. Involving end-users and relevant stakeholders throughout the cycle of design and development of assistive technology is an effective method to explore design opportunities and define creative solutions.

International audience; Background: The goal of this work is to develop a non-invasive method in order to help detecting Alzheimer's disease in its early stages, by implementing voice analysis techniques based on machine learning algorithms. Methods: We extract temporal and acoustical voice features (e.g.Jitter and Harmonics-to-Noise Ratio) from read speech of patients in Early Stage of Alzheimer's Disease (ES-AD), with Mild Cognitive Impairment (MCI), and from a Healthy Control (HC) group. Three classification methods are used to evaluate the efficiency of these features, namely kNN, SVM and decision Tree. To assess the effectiveness of this set of features, we compare them with two sets of feature parameters that are widely used in speech and speaker recognition applications. A two-stage feature selection process is conducted to optimize classification performance. For these experiments, the data samples of HC, ES-AD and MCI groups were collected at AP-HP Broca Hospital, in Paris. Results: First, a wrapper feature selection method for each feature set is evaluated and the relevant features for each classifier are selected. By combining, By combining, for each classifier, the features selected from each initial set, we improve the classification accuracy by a relative gain of more than 30 % for all classifiers. Then the same feature selection procedure is performed anew on the combination of selected feature sets, resulting in an additional significant improvement of classification accuracy. Conclusion: The proposed method improved the classification accuracy for ES-AD, MCI and HC groups and promises the effectiveness of speech analysis and machine learning techniques to help detect pathological diseases

International audience; Background : because of the rich set of spatiotemporal features it allows to extract, online handwriting is being increasingly investigated for characterizing neurodegenerative diseases like Parkinson and Alzheimer. The state of the art on the latter is dominated by methods that extract global (average) kinematic parameters, and then apply basic classification techniques or standard statistical tests to assess the statistical significance of each parameter in discriminating a pathological population from a healthy control one. Methods : we propose a new approach for characterizing Early-Stage Alzheimer disease (ES-AD), and Mild Cognitive Impairment (MCI) w.r.t Healthy Controls (HC) that, instead of considering average kinematic HW parameters, which discards the dynamics related to each subject, is based on a semi-global parameterization scheme encoding the distribution of each kinematic parameter over a mixed number of bins. Such a distribution characterizes the gross dynamic associated which each parameter. A semi-supervised learning is proposed, in which a Normalized Mutual Information (NMI) selection scheme guides a hierarchical clustering algorithm to choose the best tradeoff between the number of clusters and the discriminative power of each w.r.t to the three cognitive profiles. Results : for both global and semi-global parameters, the semi-supervised learning scheme uncovers clusters with two trends, one cluster that consist essentially of HC and MCI, and one cluster essentially composed of MCI and ES-AD. The clusters obtained with semi-global parameters are more informative than those with global parameters as reflected by a better NMI value. Conclusion : A semi-global parametrization of handwriting spatiotemporal parameters allows for a better discrimination between the HC, MCI and ES-AD profiles, than a global one does. Unlike the latter, the former encodes the distribution of the dynamics of each parameter, which offers a larger parameter space in which discrimination is easier

In the present study, we aimed to observe robot-acceptance in older adults, particularly subsequent to a1-month direct experience with a robot.Subjects and methods: Six older adults with mild cognitive impairment (MCI) and five cognitively intact healthy (CIH) older adults were recruited. Participants interacted with an assistive robot in the Living Lab once a week for4weeks. After being shown how to use the robot, participants performed tasks to simulate robot use in everyday life. Mixed methods, comprising a robot-acceptance questionnaire, semistructured interviews, usability-performance measures, and a focus group, were used.Results: Both CIH and MCI subjects were able to learn how to use the robot. However, MCI subjects needed more time to perform tasks after a 1-week period of not using the robot. Both groups rated similarly on the robot-acceptance questionnaire. They showed low intention to use the robot, as well as negative attitudes toward and negative images of this device. They did not perceive it as useful in their daily life. However, they found it easy to use, amusing, and not threatening. In addition, social influence was perceived as powerful on robot adoption. Direct experience with the robot did not change the way the participants rated robots in their acceptance questionnaire. We identified several barriers to robot-acceptance, including older adults’ uneasiness with technology, feeling of stigmatization, and ethical/societal issues associated with robot use.Conclusion: It is important to destigmatize images of assistive robots to facilitate their acceptance. Universal design aiming to increase the market for and production of products that are usable by everyone (to the greatest extent possible) might help to destigmatize assistive devices.Keywords: assistive robot, human–robot interaction, HRI, robot-acceptance, technology acceptance

Characterizing age from handwriting (HW) has important applications, as it is key to distinguishing normal HW evolution with age from abnormal HW change, potentially triggered by neurodegenerative decline. We propose, in this work, an original approach for online HW style characterization based on a two-level clustering scheme. The first level generates writer-independent word clusters from raw spatial-dynamic HW information. At the second level, each writer’s words are converted into a Bag of Prototype Words that is augmented by an interword stability measure. This two-level HW style representation is input to an unsupervised learning technique, aiming at uncovering HW style categories and their correlation with age. To assess the effectiveness of our approach, we propose information theoretic measures to quantify the gain on age information from each clustering layer. We have carried out extensive experiments on a large public online HW database, augmented by HW samples acquired at Broca Hospital in Paris from people mostly between 60 and 85 years old. Unlike previous works claiming that there is only one pattern of HW change with age, our study reveals three major aging HW styles, one specific to aged people and the two others shared by other age groups.

To bridge the gap, we launched a 2-year project, during which we conducted focus groups (FGs) with demonstrations of ICTs, allowing older adults to try them out and to share their opinions. This study aimed at investigating how participants perceived this kind of initiative and how they reacted to different kinds of ICTs.Patients and methods: In total, 14 FGs were conducted with community-dwelling older adults, with a frequency of two FGs on the same topic once per trimester. Twenty-three older adults (four men and 19 women) attended at least one FG but only nearly half of them were regular attendants (ten participating in at least five sessions). Age of participants ranged from 63years to 88years, with a mean of 77.1years. All of them had completed secondary education. The analyses of the data were performed according to inductive thematic analysis.Results: Four overarching themes emerged from the analysis. The first concerned participants’ motivation for and assessment of the project. The second theme identified the underlying factors of the “digital divide” between the younger and the older generations. The third theme concerned the factors of technology adoption among older adults. The fourth one identified participants’ attitudes toward assistive ICTs, designed specifically for older adults (“gerontechnologies”).Discussions and conclusion: This project encouraging older adults to be informed about different kinds of ICTs was positively rated. With regard to ICTs, participants perceived a digital divide. The underlying factors are generation/cohort effects, cognitive and physical decline related to aging, and negative attitudes toward technologies. However, more and more older adults adopt different kinds of ICTs in order to fit in with the society. Concerning assistive ICTs, they manifested a lack of perceived need and usefulness. Also, there was a negative image of end users of this kind of technologies. The so-called gerontechnologies specifically targeting older adults contain stigmatizing symbolism that might prevent them from adopting them.

Contains fulltext : 152329.pdf (Publisher’s version ) (Open Access) BACKGROUND: People with dementia can benefit from a palliative care approach. Recommendations, such as those of the EAPC have been proposed to strengthen the provision of palliative care for this group of patients. Yet, it remains challenging for professionals to identify when a person with dementia is in need of palliative care. The objective of this study therefore was to explore when professionals in long-term care settings consider a person with dementia in need of palliative care. METHODS: Teams with in total 84 professionals working in 13 long-term care settings from 6 countries (France, Germany, Italy, Norway, Poland and the Netherlands) received a case-vignette concerning a person with dementia recently admitted to a nursing home. Teams were asked to discuss when they considered people with dementia eligible for palliative care. The constant comparative method was used to analyse their answers. RESULTS: Three different time points in the disease trajectory when people with dementia were considered to be eligible for palliative care were extracted: (1) early in the disease trajectory; (2) when signs and symptoms of advanced dementia are present; and (3) from the time point that curative treatment of co-morbidities is futile. Yet, none of these time points was uniformly considered by the professional teams across Europe. In some cases, professionals working in the same nursing home didn't even reach consensus when considering persons with dementia eligible for palliative care. CONCLUSION: The results of the study identified that professionals across Europe have different opinions regarding the time point when to consider a person with dementia in need of palliative care.

BackgroundInformal caregivers (CGs) of patients with Alzheimer’s disease are at risk of suffering from psychological and physical weakening. Several psychoeducational interventions have been designed to prevent stress and burden of caregivers. In France, despite health authorities’ recommendations, to our knowledge there is no rigorously assessed Web-based psychoeducational program to date. ObjectiveThe objective of our study was to assess the efficacy of a French Web-based psychoeducational program (called Diapason) with an unblinded randomized clinical trial. MethodsIn this protocol, 80 informal caregivers of patients followed at Broca Hospital are recruited offline and randomized in the experimental condition (EC) or the control condition (CC). The volunteers in EC have to visit a closed online user group at least once a week and validate one new session of this fully automated Web program, during 12 weeks. Each week a new thematic is added to the website. The participants in the CC receive usual care, and have access to the Diapason program after their participation (6 months). Face-to-face evaluations for both groups are planned every 3 months (M0–M3 and M6). The main objective of this program is to provide CGs with information on the disease process, how to prevent psychological strain (using anticipation and relaxation techniques), and offering a virtual space (forum) to discuss with other caregivers. The primary outcome of this study is the self-perceived stress, while self-efficacy, burden, depression, and self-perceived health status are defined as secondary outcomes. Other variables that might have an impact on the program efficacy are collected. ResultsThis protocol was accepted for funding. The enrollment began in October 2011, and participants currently recruited will finish their evaluations in January 2014. The results are expected for June 2014. ConclusionsFindings might provide empirical evidence on: (1) the feasibility of an Internet-based program in the French context, (2) the effectiveness of a Web-based program for informal caregivers, and (3) the identification of caregivers who will benefit from this type of intervention.

International audience; Understanding how handwriting (HW) style evolves as people get older may be key for assessing the health status of elder people. It can help, for instance, distinguishing HW change due to a normal aging process from change triggered by the early manifestation of a neurodegenerative pathology. We present, in this paper, an approach, based on a 2-layer clustering scheme that allows uncovering the main styles of online HW acquired on a digitized tablet, with a special emphasis on elder HW styles. The 1st level separates HW words into writer-independent clusters according to raw spatial-dynamic HW information, such as slant, curvature, speed, acceleration and jerk. The 2nd level operates at the writer level by converting the set of words of each writer into a Bag of 1st Layer Clusters, that is augmented by a multidimensional description of his/her writing stability across words. This 2nd layer representation is input to another clustering algorithm that generates categories of writer styles along with their age distributions. We have carried out extensive experiments on a large public online HW database, augmented by HW samples acquired at Broca hospital in Paris from people mostly between 60 and 85 years old. Unlike previous works claiming that there is only one pattern of HW change with age, our study reveals basically three major HW styles associated with elder people, among which one is specific to elders while the two others are shared by other age groups
