Orientation system for people with cognitive disabilities

In health care there has been a growing interest and investment in new tools to have a constant monitoring of patients. The increasing of average life ex-pectation and, consequently, the costs in health care due to elderly population are the motivation for this investment. However, healthmonitoring is not only important to elderly people, it can be also applied to people with cognitive disabilities. In this article we present some systems, which try to support these persons on doing their day-to-day activities and how it can improve their life quality. Also, we present an idea to a project that tries to help the persons with cognitive disabilities by providing assistance in geo-guidance and keep their caregivers aware of their location.

Geo-localization System for People with Cognitive Disabilities

Technology is present in almost every simple aspect of the people’s daily life. As an instance, let us refer to the smartphone. This device is usually equipped with a GPS modulewhich may be used as an orientation system, if it carries the right functionalities. The problem is that these applications may be complex to operate and may not be within the bounds of everybody. Therefore, the main goal here is to develop an orientation system that may help people with cognitive disabilities in their day-to-day journeys, when the caregivers are absent. On the other hand, to keep paid helpers aware of the current location of the disable people, it will be also considered a localization system. Knowing their current locations, caregiversmay engage in others activities without neglecting their prime work, and, at the same time, turning people with cognitive disabilities more independent.

Participação ocupacional do idoso com deficiência visual: sua percepção

O estudo apresentado visava responder às necessidades emergentes de justificação da intervenção da Terapia Ocupacional na população idosa com deficiência visual. Teve como objectivo explorar as perspectivas dos idosos com deficiência visual na experiência que têm da sua participação ocupacional. Paralelamente a este objectivo procurou-se, também, conhecer as atitudes e comportamentos em relação ao apoio da Terapia Ocupacional. Para estudar estas questões utilizou-se uma metodologia qualitativa, a fenomenologia, que permitiu descrever fielmente a experiência que se pretendia conhecer. A recolha de dados foi feita através de duas sessões de focus groups distintas, onde num dos grupos participaram idosos com deficiência visual que tiveram apoio de Terapia Ocupacional e no outro idosos com deficiência visual que não usufruíram deste apoio. Após a análise do conteúdo resultante dos focus groups emergiram os seguintes temas: impacto da deficiência visual, onde foram englobadas as categorias de implicações psicossociais da deficiência visual e restrições nas actividades e ocupações do idoso com deficiência visual; o segundo tema onde se incluíram as categorias de apoio e atitudes sociais, instituições e recursos acessíveis e estratégias utilizadas; por fim o tema dos benefícios percebidos, do qual fazem parte as categorias, benefícios psicológicos e participação. Estes temas permitiram perceber as perspectivas de participação ocupacional do idoso, após o aparecimento da deficiência visual, bem como conhecer as melhorias ao nível dessa participação após intervenção especializada, destacando-se a relevância da intervenção do terapeuta ocupacional na população idosa com deficiência visual.

Quality of life of the caregivers of people with aphasia. A systematic review.

Purpose: Systematic review to identify the factors associated to the quality of life (QOL) of the caregivers of people with aphasia (PWA). Methods: Studies were searched using Medline, Pubmed, Cochrane Library, CINAHL, PsycINFO and Web of Science databases. Peer-reviewed papers that studied the QOL of PWA’s caregivers or the consequences of aphasia in caregivers’ life were included. Findings were extracted from the studies that met the inclusion criteria. Results: No data is available reporting particularly the QOL of PWA caregivers’ or their QOL predictors. Nevertheless, it was possible to extract aspects related to QOL from the studies that report the consequences of aphasia, and life changes in PWA’s caregivers. Nine (9) studies including PWA’s caregivers were found, but only 5 reported data separately on them. Methodological heterogeneity impedes cross-study comparisons, although some considerations can be made. PWA’s caregivers reported life changes such as: loss of freedom; social isolation; new responsibilities; anxiety; emotional loneliness; need for support and respite. Conclusions: Changes in social relationships, in emotional status, increased burden and need for support and respite were experienced by PWA’s caregivers. Stroke QOL studies need to include PWA caregivers’ and report separately on them. Further research is needed in this area in order to determine their QOL predictors and identify what interventions and referrals better suit their needs.

Characterisation of adventitious lung sounds in people with dementia

Introduction: Lower Respiratory Tract Infections (LRTIs) are highly prevalent in institutionalised people with dementia, constituting an important cause of morbidity and mortality. Computerised auscultation of Adventitious Lung Sounds (ALS) has shown to be objective and reliable to assess and monitor respiratory diseases, however its application in people with dementia is unknown. Aim: This study characterised ALS (crackles and wheezes) in institutionalised people with dementia. Methods: An exploratory descriptive study, including 6 long-term care institutions was conducted. The sample included a dementia group (DG) of 30 people with dementia and a match healthy group (HG) of 30 elderly people. Socio-demographic and anthropometric data, cognition, type and severity of dementia, cardio-respiratory parameters, balance, mobility and activities and participation were collected. Lung sounds were recorded with a digital stethoscope following Computerised Respiratory Sound Analysis (CORSA) guidelines. Crackles’ location, number (N), frequency (F), two-cycle duration (2CD), initial deflection width (IDW) and largest deflection width (LDW) and wheezes’ number (N), ratio (R) and frequency (F) were analysed per breathing phase. Statistical analyses were performed using PASW Statistics(v.19). Results: There were no significant differences between the two groups in relation to the mean N of crackles during inspiration and expiration in both trachea and thorax. DG trachea crackles had significant higher F during inspiration and lower IDW, 2CD and LDW during expiration when compared with HG. At the thorax, the LDW during inspiration was also significantly lower in the DG. A significant higher N of inspiratory wheezes was found in the HG. Both groups had a low ratio of high frequency wheezes. Conclusion: Computerised analyses of ALS informed on the respiratory system and function of people with dementia and elderly people. Hence, this could be the step towards prevention, early diagnosis and continuous monitoring of respiratory diseases in people with cognitive impairment.

Autonomous Surface Vehicle Docking Manoeuvre with Visual Information

This work presents a hybrid coordinated manoeuvre for docking an autonomous surface vehicle with an autonomous underwater vehicle. The control manoeuvre uses visual information to estimate the AUV relative position and attitude in relation to the ASV and steers the ASV in order to dock with the AUV. The AUV is assumed to be at surface with only a small fraction of its volume visible. The system implemented in the autonomous surface vehicle ROAZ, developed by LSA-ISEP to perform missions in river environment, test autonomous AUV docking capabilities and multiple AUV/ASV coordinated missions is presented. Information from a low cost embedded robotics vision system (LSAVision), along with inertial navigation sensors is fused in an extended Kalman filter and used to determine AUV relative position and orientation to the surface vehicle The real time vision processing system is described and results are presented in operational scenario.
