Self-regulated music stimulation for persons with Alzheimer's disease: impact assessment and social validation

The use of technology by seniors with neurocognitive disorders in long-term care: a scoping review

BACKGROUND

To map the current state of knowledge about the use of technology with seniors with neurocognitive disorders in long-term care to foster interactions, wellness, and stimulation.

METHODS

Cumulative Index to Nursing and Allied Health Literature (CINAHL Plus); MEDLINE; PsycINFO; Embase and Web of Science were searched in eligible literature, with no limit of time, to describe the current use of technology by seniors with neurocognitive disorders in long-term care. All types of literature were considered except for theses, editorial, social media. This scoping review was built around the recommendations of Peters et al. (2020 version). Three researchers collaborated on the selection of articles and independently reviewed the papers, based on the eligibility criteria and review questions.

RESULTS

The search yielded 3,605 studies, of which 39 were included. Most technology type reported was robotics. Included studies reports different positive effects on the use of such technology such as increase of engagement and positive.

CONCLUSION

The study highlights different types and potential benefits of technology for long-term care residents with neurocognitive disorders, emphasizing the crucial need for additional research to refine interventions and their use.

Benefits in Alzheimer's Disease of Sensory and Multisensory Stimulation

Alzheimer's disease (AD) is a serious neurodegenerative disease, which seriously affects the behavior, cognition, and memory of patients. Studies have shown that sensory stimulation can effectively improve the cognition and memory of AD patients, and its role in brain plasticity and neural regulation is initially revealed. This paper aims to review the effect of various sensory stimulation and multisensory stimulation for AD, and to explain the possible mechanism, so as to provide some new ideas for further research in this field. We searched the Web of Science and PubMed databases (from 2000 to October 27, 2020) for literature on the treatment of AD with sensory and multisensory stimulation, including music therapy, aromatherapy, rhythmic (e.g., visual or acoustic) stimulation, light therapy, multisensory stimulation, and virtual reality assisted therapy, then conducted a systematic analysis. Results show these sensory and multisensory stimulations can effectively ameliorate the pathology of AD, arouse memory, and improve cognition and behaviors. What's more, it can cause brain nerve oscillation, enhance brain plasticity, and regulate regional cerebral blood flow. Sensory and multisensory stimulation are very promising therapeutic methods, and they play an important role in the improvement and treatment of AD, but their potential mechanism and stimulation parameters need to be explored and improved.

Awareness in severe Alzheimer's disease: a systematic review

Objective: There is limited understanding about how people in the severe stages of Alzheimer's disease (AD) experience and demonstrate awareness. We synthesised all available evidence with the aim of understanding how awareness is preserved or impaired in severe AD and what evidence there is for different levels of awareness according to the levels of awareness framework.Method: A systematic search of the following databases: Embase, PsycINFO, MEDLINE and Web of Science was carried out. A narrative synthesis and analysis was conducted of all included studies. All studies were assessed for quality using the AXIS and CASP tools.Results: Our findings suggest that lower level sensory awareness is relatively maintained in severe AD. Findings for higher level awareness are variable and this may be related to the diversity of methods that have been used to explore awareness in these circumstances.Conclusion: Awareness is complex, heterogeneous and varies significantly between individuals. Environmental and contextual factors have a significant impact on whether awareness is observed in people with severe AD. Adaptation of the environment has the potential to facilitate the expression of awareness while education of caregivers may increase understanding of people with severe AD and potentially improve the quality of care that is received.

Tablet-based intervention to foster music-related hand responses and positive engagement in people with advanced Alzheimer’s disease

Purpose

Music stimulation is considered beneficial for people with advanced Alzheimer’s disease. The purpose of this paper is to assess a tablet-based program to promote music-related hand responses and positive engagement (e.g. singing or moving the body with the music) in people with advanced Alzheimer’s disease.

Design/methodology/approach

The program was implemented with 20 participants according to a non-concurrent multiple baseline design across participants. The participants were provided with a tablet whose screen worked as a sensor. During the intervention, sensor activations by hand responses led the tablet to present 10 s segments of preferred songs; an absence of sensor activation led the tablet to produce a prompt.

Findings

The participants’ mean frequencies of hand responses (i.e. sensor activations) per 5 min session increased from mostly zero during baseline to between about 9 and 20 during the intervention. The mean percentages of observation intervals with participants’ positive engagement increased from 0 to 12 during the baseline to between 13 and 55 during the intervention. The differences between baseline and intervention data were statistically significant for all participants.

Originality/value

A tablet-based program, such as that used in this study, may help people with advanced Alzheimer’s disease develop specific music-related responses and positive engagement.

Positive physical and mental outcomes for residents in nursing facilities using music: a systematic review

Objectives

The objective of this study was to investigate the applicability and effectiveness of the use of music in providing for positive physical and mental outcomes in nursing facilities.

Problem

Lack of quality of life (QOL) has been a significant issue within nursing facilities. With the rise in census due to Baby Boomers, it has become imperative to find ways to increase overall QOL.

Methods

The research team participants conducted a literature review via Cumulative Index of Nursing and Allied Health Literature, PubMed (MEDLINE), and Academic Search Ultimate to collect data regarding the use of music to provide for positive physical and mental outcomes in nursing facilities.

Results

The most common facilitator mentioned was increased socialization or communication (18%), followed by reduced depression (12%), improved physical health (11%), and reduced agitation or behavior problems (9%). The most common barriers were as follows: cannot isolate effects of music (26%), cost prohibitive (11%), difficult to implement (11%), and no significant improvements in QOL or well-being (11%).

Conclusion

The use of music showed positive outcomes for residents in nursing facilities and should be considered for implementation as part of the normal culture within such facilities.

Occupational Therapy Interventions for People With Alzheimer's Disease

Evidence Connection articles provide a clinical application of systematic reviews developed in conjunction with the American Occupational Therapy Association's (AOTA's) Evidence-Based Practice Project. In this Evidence Connection article, we describe a case report of a person with Alzheimer's disease. The occupational therapy assessment and intervention process in the home setting is described. Findings from the systematic reviews on this topic were published in the November/December 2017 issue of the American Journal of Occupational Therapy and in AOTA's Occupational Therapy Practice Guidelines for Adults With Alzheimer's Disease and Related Major Neurocognitive Disorders. Each article in this series summarizes the evidence from the published reviews on a given topic and presents an application of the evidence to a related clinical case. Evidence Connection articles illustrate how the research evidence from the reviews can be used to inform and guide clinical reasoning.

Effectiveness of Environment-Based Interventions That Address Behavior, Perception, and Falls in People With Alzheimer's Disease and Related Major Neurocognitive Disorders: A Systematic Review

OBJECTIVE

This systematic review evaluated the effectiveness of environment-based interventions that address behavior, perception, and falls in the home and other settings for people with Alzheimer's disease (AD) and related major neurocognitive disorders (NCDs).

METHOD

Database searches were limited to outcomes studies published in English in peer-reviewed journals between January 2006 and April 2014.

RESULTS

A total of 1,854 articles were initially identified, of which 42 met inclusion criteria.

CONCLUSION

Strong evidence indicates that person-centered approaches can improve behavior. Moderate evidence supports noise regulation, environmental design, unobtrusive visual barriers, and environmental relocation strategies to reduce problematic behaviors. Evidence is insufficient for the effectiveness of mealtime ambient music, bright light, proprioceptive input, wander gardens, optical strategies, and sensory devices in improving behavior or reducing wandering and falls. Although evidence supports many environment-based interventions used by occupational therapy practitioners to address behavior, perception, and falls in people with AD and related major NCDs, more studies are needed.

Persons With Advanced Alzheimer’s Disease Engage in Mild Leg Exercise Supported by Technology-Aided Stimulation and Prompts

This study assessed whether nine persons with advanced Alzheimer’s disease would learn to engage in leg responses (exercise) with the support of a technology-aided program, which provided (a) preferred stimulation contingent on the leg responses and (b) verbal reminders/prompts in case of no responding. The study was conducted according to a non-concurrent multiple baseline design across participants and involved sessions of 5 min. During the baseline, the participants’ mean frequencies of leg responses ranged from zero to slightly above two per session. During the intervention, those frequencies ranged from nearly 10 to nearly 17 per session. The mean frequencies of prompts varied across participants from about two to more than seven per session. In addition to the increase in leg responses, participants showed an increase in signs of positive personal involvement (e.g., smiles and positive verbalizations) during the intervention sessions as compared with the baseline sessions. The applicability and potential benefits of the program in daily contexts are discussed.

Effects of response-related music stimulation versus general music stimulation on positive participation of patients with Alzheimer's disease

OBJECTIVE

Assessing the effects of response-related music stimulation versus general (response-unrelated) music stimulation on positive participation of 11 new patients with Alzheimer's disease.

METHOD

The patients were functioning in the severe and low-moderate ranges of the disease. Positive participation included behaviors such as, singing or rhythmic movements and smiles. Both music conditions relied on the display of music/song videos on a computer screen. In the response-related (active) condition, the patients used a simple hand response and a microswitch to determine music stimulation inputs. In the general (unrelated/passive) condition, music stimulation was automatically presented throughout the sessions.

RESULTS

Data showed that six of the 11 patients had higher levels of positive participation in the response-related stimulation condition. The remaining five patients did not have differences between the two conditions.

CONCLUSION

Based on this evidence and previous findings, one might consider the use of the active condition beneficial for daily programs.

Persons with Alzheimer's disease engage in leisure and mild physical activity with the support of technology-aided programs

Three studies were conducted to assess technology-aided programs to promote leisure engagement and mild physical activity in persons with Alzheimer's disease. Specifically, Study I assessed a program aimed at enabling three patients with mild or moderate Alzheimer's disease to choose among different music options and activate the preferred ones. Studies II and III were directed at patients in the low moderate or severe stages of the Alzheimer's disease who were no longer capable of ambulating and spent their time generally inactive, sitting in their wheelchairs. In particular, Study II used a program to help three patients exercise an arm-raising movement. Study III used a program to help three patients exercise a leg-foot movement. Each study was carried out according to a nonconcurrent multiple baseline design across patients. Results were very encouraging. The patients of Study I learned to choose and activate their preferred music pieces. The patients of Studies II and III enhanced their performance of the target movements and increased their indices of positive participation (e.g., smiles and verbalizations) during the sessions. The applicability of the programs in daily contexts and their implications for the patients involved are discussed.

A computer-aided program for helping patients with moderate Alzheimer's disease engage in verbal reminiscence

This study assessed a simple computer-aided program for helping patients with moderate Alzheimer's disease engage in verbal reminiscence. In practice, the program was aimed at fostering the patient's verbal engagement on a number of life experiences/topics previously selected for him or her and introduced in the sessions through a friendly female, who appeared on the computer screen. The female asked the patient about the aforementioned experiences/topics, and provided him or her with positive attention, and possibly verbal guidance (i.e., prompts/encouragements). Eight patients were involved in the study, which was carried out according to non-concurrent multiple baseline designs across participants. Seven of them showed clear improvement during the intervention phase (i.e., with the program). Their mean percentages of intervals with verbal engagement/reminiscence ranged from close to zero to about 15 during the baseline and from above 50 to above 75 during the intervention. The results were discussed in relation to previous literature on reminiscence therapy, with specific emphasis on the need for (a) replication studies and (b) the development of new versions of the technology-aided program to improve its impact and reach a wider number of patients.

Persons with moderate Alzheimer's disease use simple technology aids to manage daily activities and leisure occupation

Two studies assessed technology-aided programs to support performance of daily activities and selection/activation of music items with patients with moderate Alzheimer's disease. In Study I, four patients were presented with activity-related pictorial instructions via a computer fitted with inexpensive, commercial software. In Study II, four patients were (a) presented with different music options and (b) allowed to select and activate the preferred option via a microswitch response. Study I showed that each patient learned to perform the two activities available with percentages of correct responses exceeding 85 by the end of the intervention. Study II showed that all patients learned to choose and activate music options. Psychology students, employed in a social validation check, scored the patients' behavior within the program better than their behavior in a control situation. The relevance and usability of simplified pictorial-instruction programs and music choice programs for patients with moderate Alzheimer's disease were discussed.

Assessing the impact and social perception of self-regulated music stimulation with patients with Alzheimer's disease

We assessed the impact and social rating of an active and a passive music condition implemented with six patients with Alzheimer's disease. In the active condition, the patients used a simple hand response and a microswitch to self-regulate music stimulation inputs. In the passive condition, music stimulation was automatically presented throughout the sessions. Active and passive stimulation sessions were preceded and followed by control (non-stimulation) sessions. The active condition sessions showed an increase in the patients' indices of positive participation (e.g., singing or music-related movements, and smiles) greater than that observed in the passive condition sessions for five of the six patients. Positive intervention effects could also spread to the post-intervention sessions. Social raters (42 care and rehabilitation staff members working with persons with multiple disabilities) favored the active condition on a six-item questionnaire dealing with, among others, conditions' suitability, respect of patients' dignity and independence, and practicality. The implications of the findings as to the plausibility/desirability of an active stimulation condition were discussed.
