Promoting supported ambulation in persons with advanced Alzheimer’s disease: a pilot study

Use of technology to sustain mobility in older people with cognitive impairment and dementia: a scoping review

PURPOSE

This paper provides a review of studies that evaluated technology devices to sustain various forms of mobility in older people with cognitive impairment or dementia and mobility problems (e.g., inability to ambulate or difficulties to orient with consequent failures to reach relevant destinations).

METHODS

A literature search was performed for English language articles indexed in PubMed, PsycINFO, and Web of Science. This search was then supplemented with an ancestral and forward search. The search covered the period ranging between January 2010 and October 2020.

RESULTS

Twenty-seven articles were included in the review. They were divided into four groups according to whether they aimed to promote (a) supported ambulation, (b) use of safe power wheelchair, (c) ambulation guided by orientation cues, and (d) ambulation with GPS-based assistance. The studies were coded in terms of the objective pursued, technology used, participants involved, strategies applied to assess the technology, and outcome reported.

CONCLUSION

A variety of technology devices are available to address the mobility problems of older people with cognitive impairment or dementia. The devices' accessibility and usability differ widely. Data on their impact are still largely preliminary and new systematic research is needed.IMPLICATIONS FOR REHABILITATIONA variety of mobility problems may afflict older people with cognitive impairment or dementia and curtail their opportunities to freely move indoor or outdoor.Technology devices have been developed to (a) promote forms of supported ambulation, (b) facilitate safe use of power wheelchairs, (c) deliver orientation/navigation cues, and (d) ensure tracking and possible assistance.The technology devices differ in terms of accessibility and affordability, with some of them readily available and others at a developmental stage.Data on the effectiveness of the various technology devices in reducing the impact of the mobility problems are still largely preliminary and new systematic research is needed.

Evaluating the Facilitators, Barriers, and Medical Outcomes Commensurate with the Use of Assistive Technology to Support People with Dementia: A Systematic Review Literature

Background: Assistive technologies (AT) have been used to improve the daily living conditions of people living with dementia (PWD). Research supports the positive impact of the use of AT such as decreased burden on caregivers and behavioral support for people with dementia. Four reviews in the last six years have analyzed AT and PWD, but none have incorporated the dimension of medical outcomes. Objectives: The purpose of this review is to identify the facilitators, barriers, and medical outcomes commensurate with the use of AT with PWD. Method: This review queried The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Web of Science, Science Direct, and PubMed databases for peer-reviewed publications in the last five years for facilitators, barriers, and medical outcomes commensurate with the use of AT with PWD. The study is reported and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and the Kruse Protocol for conducting a systematic review. Results: 48 studies were analyzed. Fourteen types of AT, 17 facilitators, 17 barriers, and 16 medical outcomes were identified in the literature. The two most frequently mentioned ATs were cognitive stimulators (9/48, 19%) and social robots (5/48, 10%). The two most frequently mentioned facilitators were caregivers want AT (8/68, 12%) and enables increased independence (7/68, 10%). The top two barriers were cost (8/75, 11%) and PWD reject AT (8/75, 11%). The top medical outcomes were improved cognitive abilities (6/69, 9%), increased activities of daily living (ADLs), and increased autonomy (each at 5/69, 7%): Zero negative outcomes were reported. Conclusion: The systematic review revealed the positive relations that occur when PWD and their caregivers use AT. Although many reservations surrounding the use of AT exist, a majority of the literature shows a positive effect of its use. Research supports a strong support for AT by caregivers due to many positive medical outcomes, but also a reticence to adopt by PWD. If ATs for PWD are a way to reduce stress on caregivers, barriers of cost and complexity need to be addressed through health policy or grants.

Technical quality of online resources for mobility device training

Purpose: Training is recommended to improve safe and effective use of mobility aids. The internet offers a large amount of information and it can be difficult to identify resources with good quality. This project aimed to create a catalogue of online educational resources for mobility device training. The objective of this study was to identify and assess the quality of existing online educational resources for mobility device training for individuals with physical disabilities and caregivers.Methods: A Google search was conducted in October 2016 and replicated in January 2018. Resources were included if they were educational, were available in English or French, provided instruction or training in mobility aid use, were free of charge, and were targeted towards mobility device users or their caregivers. Resources were assessed using a modified version of the Journal of the American Medical Association (JAMA) benchmarks for the evaluation of technical quality.Results: Two hundred and seventy-one resources were included in the final analysis. Two resources were added by the research team for a total of 273 resources. The average JAMA quality score per mobility device varied between 3 (for crutches) and 5 (for knee scooters) out of 6, and weighted average was 3.6. The two resources added by the research team obtained a JAMA quality score of 6. 58 resources were retained for the catalogue.Conclusions: The results suggest that the technical quality of online educational resources for mobility device training could be improved. A need for higher quality resources for device users and caregivers was identified.Implications for rehabilitationThe overall technical quality of online educational resources for mobility device training for users and caregivers is low.A Mobility Device Training Catalogue is freely available and summarizes the highest quality online resources found on mobility device training.The Mobility Device Training Catalogue is intended for use by users and caregivers, but it may also provide clinicians with a tool that may be shared with their clients.

Diagnostic and interventional implications of telemedicine in Alzheimer's disease and mild cognitive impairment: A literature review

INTRODUCTION

Worldwide, life expectancy, and aging-related disorders as mild cognitive impairment (MCI) and Alzheimer disease (AD) are increasing, having a rising impact on patients' quality of life and caregivers' distress. Telemedicine offers many possibilities, such as remote diagnosing and monitoring of patients.

OBJECTIVE

The purpose of this study is to provide a narrative synthesis of the literature about the implementation of telemedicine for diagnosis, treatment, and follow-up of patients with AD and MCI and their caregivers.

METHODS

A systematic literature review was conducted on MEDLINE, EMBASE, and the Cochrane Library databases up to September 2018. MCI or AD diagnoses were the conditions of interest. We excluded other dementias.

RESULTS

Fifty-six articles met inclusion criteria. We identified two main categories: diagnosis group (DG) and follow-up/interventional group (FIG). Fifteen articles suggested how to make a remote or earlier diagnosis: four were case-control accuracy studies, nine were paired comparative accuracy studies, and two were prospective single-arm accuracy studies. Among these, four focused on MCI, six on AD, and five on both. Forty one focused on supporting patients during the stages of the disease (28 articles), patient's caregivers (nine articles), or both (four articles).

CONCLUSIONS

The rising use of telemedicine could actively improve AD and MCI patients' lives, reduce caregivers' burden, and facilitate an early diagnosis if patients live in remote places. However, as some studies report, it is relevant to take into account the emotional impact of telemedicine on patients and not only on the effectiveness.

Smartphone technology for fostering goal-directed ambulation and object use in people with moderate Alzheimer's disease

Purpose: This study was aimed at assessing a smartphone-based intervention to help 11 individuals with moderate Alzheimer's disease and ambulation problems to manage goal-directed, walker-assisted ambulation and object use (i.e., to reach specific destinations and put away objects at those destinations independently).Method: The study was carried out according to a non-concurrent multiple baseline design across participants. Two measures were recorded, that is, the number of target responses performed correctly (with each target response consisting of reaching a destination and putting away an object), and the number of observation intervals with indices of enjoyment/appreciation (e.g., smiles and positive comments). During baseline, the participants were provided with a walker and three objects that were to be transported to and put away at specific destinations. During the intervention, the participants also had the smartphone-based technology that provided them with instructions about the destinations and objects, praise, and preferred stimulation.Results: During baseline, the mean frequency of correct target responses was virtually zero. The mean frequency of intervals with indices of enjoyment/appreciation ranged from zero to close to one. During the intervention, the mean frequencies for the two measures were slightly below three and just over three, respectively. The maximum frequencies possible were three and four, respectively.Conclusions: A smartphone-based intervention may be suitable to foster goal-directed, walker-assisted ambulation and object use as well as enjoyment/appreciation in participants like those involved in this study.IMPLICATIONS FOR REHABILITATIONA smartphone-based intervention may be used to promote goal-directed, walker-assisted ambulation and object use as well as indices of enjoyment/appreciation in persons with moderate Alzheimer disease.The technology for such intervention might involve (a) a smartphone with Android operating system, light sensor, Bluetooth v4.0, and MacroDroid, (b) Bluetooth headphones or earpieces, and (c) battery-powered light sources.The technology may provide the participants with instructions about the destinations to reach and the objects to put away at those destinations, and with praise and brief periods of preferred stimulation at the target destinations.The technology may be considered easy to access, friendly for the participants, and suitable for use by staff within daily contexts.

Smartphone-Based Interventions to Foster Simple Activity and Personal Satisfaction in People With Advanced Alzheimer's Disease

OBJECTIVES

This study assessed a smartphone-based program to promote practical and mildly demanding arm responses and personal satisfaction and increase physical exertion (heart rates) in people with advanced Alzheimer's disease.

METHODS

The program relied on a Samsung Galaxy A3 smartphone with Android 6.0 operating system. Two groups of 10 and 11 participants, respectively, were assigned different responses (ie, placing cards into an elevated box and moving bottles with water from a table into a container). Responses activated the smartphone, which produced brief periods of preferred stimulation. Lack of responding led the smartphone to produce a verbal prompt.

RESULTS

All participants had significant increases in independent response frequencies, level of personal satisfaction, and heart rates during program sessions as opposed to baseline or control sessions.

CONCLUSION

A smartphone-based program may help people with advanced Alzheimer's disease increase independent occupation with possible benefits in terms of satisfaction and physical condition.

Memory for familiar locations: The impact of age, education and cognitive efficiency on two neuropsychological allocentric tasks

This research aims to reconsider and support the use of spatial tasks based on familiar geographical information in the neuropsychological assessment of topographical (dis)orientation. Performance on two spatial tasks based on familiar information -l andmark positioning on a map and map of Italy - were compared in two studies assessing allocentric orientation among young and healthy elderly with different levels of education (Study 1) and elderly with and without probable cognitive impairment (Study 2). Results from Study 1 showed that the map of Italy task was affected by education, while the landmark positioning on a map was not. Results of Study 2 showed that both tasks were sensitive to different levels of cognitive functioning in a sample of community-dwelling seniors. Overall, spatial tasks based on mental representation of the hometown environment may be an important supplement in the assessment of allocentric topographical disorientation, discriminating typical from atypical aging.

Technology-Based Behavioral Interventions for Daily Activities and Supported Ambulation in People With Alzheimer's Disease

OBJECTIVES

These 2 studies evaluated technology-based behavioral interventions for promoting daily activities and supported ambulation in people with mild-to-moderate and moderate-to-severe Alzheimer's disease, respectively.

METHODS

Study 1 included 8 participants who were taught to start and carry out daily activities on their own using a tablet or smartphone device, which provided activity reminders, step instructions, and praise. Study 2 included 9 participants who were taught to engage in brief periods of ambulation using a walker combined with a tilt microswitch and a notebook computer, which monitored step responses and provided stimulation and prompts.

RESULTS

The participants of study 1 succeeded in starting the activities independently and carrying them out accurately. The participants of study 2 largely increased their ambulation levels and also showed signs of positive involvement (eg, smiles and verbalizations).

CONCLUSION

The aforementioned technology-based interventions may represent practical means for supporting people with Alzheimer's disease.
