Effects of Different Mind-body Exercises in Managing Chronic Pain of Older Adults: A Network Meta-analysis of Randomized Trials.

INTRODUCTION: Mind-body exercises (MBEs) were shown to be effective in managing chronic pain among older adults in several recent studies. However, the differences in the effects of different MBEs remained unclear. OBJECTIVE: To compare the effects of different MBEs in managing chronic pain in older adults. METHODS: Eight databases were searched for studies published between 2012 and 2023, and 14 studies were included in this systematic review and network meta-analysis (NMA). The NMA was performed using R and Metainsight. RESULTS: Results showed that tai chi and yoga were effective in alleviating chronic pain, but their effects were not superior to traditional physical exercises and other MBEs. In addition, none of the MBEs were shown to be effective in mitigating chronic pain-related disabilities. CONCLUSION: Tai chi and yoga can be used for relieving chronic pain in older adults; however, MBE programs alone were not sufficient to mitigate chronic pain-related disabilities.

Establishing psychometric properties of the older volunteer competency scale in the community.

AIM(S): To investigate the factorial structure, test-retest reliability, and internal consistency of the Older Volunteer Competency Scale and establish its psychometric properties. DESIGN: Cross-sectional survey. METHODS: A total of 1,000 older volunteers were recruited through random sampling and asked to complete the Older Volunteer Competency Scale. Subsequently, 100 participants were selected to participate in a second test to determine the scale's test-retest reliability. Factorial structure was assessed through exploratory factor analysis and confirmatory factor analysis, and internal consistency was assessed using Cronbach's α. RESULTS: Favorable exploratory and confirmatory factor analysis results were obtained. In addition, the three dimensions of the Older Volunteer Competency Scale, namely service awareness, service skills, and interpersonal interaction, had high internal consistency and test-retest reliability. CONCLUSION: The Older Volunteer Competency Scale is an effective and reliable research instrument for evaluating competency and needs among older volunteers.

Inequality in Older Volunteering: Association Between Volunteer Competency and Demographic Profiles.

The present survey research investigated older people's volunteering competency relating to social inequality by exploring the latent ability profile and demographic correlates of 1,000 older volunteers in 73 community care centersin southern Taiwan. Older volunteers were classified into advanced (n = 509), basic (n = 214), and novice (n = 277) groups. Demographics examined included: individualistic characteristics (religious beliefs), resources (education; number of chronic diseases), andsocial factors (serving area and spoken language, volunteering duration, marital status, and gender). Apparent inequality issues were revealed. The advanced group was better educated, Mandarin-speaking, and in urban areas. while the novice group featured the opposite (lower education Taiwanese-speaking suburban areas).

Comparing Different Stretching Exercises on Pain, Stiffness, and Physical Function Disability in Older Adults With Knee Osteoarthritis.

OBJECTIVE: To assess and compare the effects of different stretching exercise programs on pain, stiffness, and physical function disability in older adults with knee osteoarthritis (KOA). DATA SOURCES: This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline for network meta-analysis (NMA). Relevant randomized controlled trials were identified by searching 7 databases up to December 2022. STUDY SELECTION: Inclusion criteria included (1) older adults with KOA; (2) intervention included stretching exercises; (3) control groups received no stretching exercise; and (4) outcome measurements included pain, stiffness, or physical function disability. Methodological quality was assessed using the Cochrane risk-of-bias tool for randomized trials version 2. DATA EXTRACTION: NMA was performed using R and MetaInsight, with results presented as a standardized mean difference (SMD) with 95% confidence interval (CI). DATA SYNTHESIS: We examined 17 studies, and NMA results indicated that proprioceptive neuromuscular facilitation (PNF) stretching, mind-body exercises, and multi-component exercise programs were effective in mitigating pain in older adults with KOA (SMD=2.54 [95% CI: 1.23; 3.84], SMD=1.09 [95% CI: 0.27; 1.92], SMD=0.57 [95% CI: 0.06; 1.09]). Moreover, mind-body exercises and multi-component exercises were the most effective programs in reducing stiffness (SMD=1.31 [95% CI: 0.12; 2.51]) and physical function disability (SMD=1.67 [95% CI: 0.01; 3.33]) in older adults with KOA, respectively. CONCLUSION: Findings suggest that PNF stretching, mind-body exercises, and multi-component exercises can be incorporated into exercise programs to better mitigate pain, stiffness, and physical function disability in older adults with KOA.

Medications for Chronic Conditions and Mortality in Older Adults.

BACKGROUND: With the population aging, examining the relationship between polypharmacy and mortality based on population data sources is important for clinical management and policy direction. OBJECTIVES: This study aimed to examine the association between the number of chronic medications and the risk of mortality in older adults. METHODS: This population-based retrospective cohort study used data from the National Health Insurance Research Database in Taiwan for information regarding chronic medication use (over 4 years) in older adults aged 65 years and older. The association between medication use and mortality numbers was analyzed using Cox proportional hazards regression models adjusted for demographic variables and comorbidity. RESULTS: The number of medications was significantly associated with high mortality risk. Within polypharmacy, being 65-74 years old, male, living in northern Taiwan, having one type of comorbid disease, and receiving <84 days of refillable chronic prescription were associated with greater mortality risk. Subgroup analyses' results regarding comorbidity showed significant positive associations between the number of medications and mortality in most comorbid diseases except for mental disorders and diseases of the skin and subcutaneous tissue. DISCUSSION: General practitioners should know that chronic polypharmacy is associated with increased mortality risk. Recognizing the possible adverse effects of multiple medication use could help physicians optimize drug regimens in the future.

[Precision Health in Nursing Practice].

Precision health is a new trend in medical care that follows in the footsteps of precision medicine. While precision medicine focuses on treating diseases after occurrence, precision health places greater emphasis on preventative healthcare and health empowerment to prevent and predict disease. Precision health aims to assess the social, economic, cultural, and environmental factors of individuals based on their unique biology, genomics, and other factors and to provide personalized healthcare, preventive medicine, and health promotion through disease prediction to empower people to lead the best possible healthy life. Precision healthcare is the focus of development in advanced countries. Disease diagnosis, treatment, and the successful implementation of precision health needs are optimized using technology such as genomic testing in combination with individual clinical and health information. Precision health focuses on the early identification of risks and prevention. Nursing staff should integrate evidence-based precision health and provide the best medical services and personalized care to each individual to achieve the best quality of life.

[Concept Analysis of Fusion Leadership].

Important concepts in leadership management related to the field of medical care management include servant leadership, charismatic leadership, and transformational leadership. Since the 2020 emergence of the coronavirus pandemic, the world has faced the immediate challenges of epidemic prevention and control. Although national government and medical system officials as well as scholars have weighed in on this issue, their leadership does not appear to line up the core ideas of leadership. Daft and Lengel (2000) examined the influence of fusion leadership on individuals and organizations. The fusion of many nuclei of leadership intentions will produce great power and influence. To elucidate the concept of integrated leadership for individuals and organizations in the post-pandemic healthcare system, this paper summarizes the defining characteristics of fusion leadership based on the conceptual analysis method of Walker and Avant (2019). Concurrently, we confirm the antecedents and consequences of fusion leadership, use different cases to illustrate the analysis, and share the reference indicators and measurements of fusion leadership to provide a reference for healthcare system administrators.

Types of Voluntary Work and Influence of Participation for Older Volunteers: A Systematic Review of Qualitative Studies.

This systematic review synthesized findings on socio-demographic characteristics of older adults who engaged in formal volunteering, types of voluntary work for engagement, and the outcomes resulting from different types of voluntary work participation. Studies published in peer-reviewed journals were identified from six electronic databases. Studies were included if they: (1) involved a study sample of adults aged 65 and older or had a mean age of 65 , (2) reported any type of formal voluntary work at any setting, and (3) reported at least one influence of voluntary work on volunteers. Older adults who were female, married, retired, and have a higher education, fair health, and more volunteering experience participated in voluntary work. The majority of older volunteers preferred to volunteer in a community setting, and they most commonly participated in healthcare or social care related voluntary work. The older volunteers perceived positive influences mostly related to health-relatedoutcomes or helping knowledge and skills.

The effect of music interventions on chronic pain experienced by older adults: A systematic review.

PURPOSE: To synthesize results from multiple studies to determine the effects of music interventions on chronic pain in older adults. DESIGN: This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline to identify and select studies. METHODS: Relevant studies were identified from nine electronic databases. The Joanna Briggs Institute (JBI) critical appraisal checklists were employed to assess methodological quality. All authors performed screening, data extraction, and synthesis. Inclusion criteria were clinical trials investigating music for chronic pain in older adults aged 65 and older. FINDINGS: Eight studies involving 524 older adults were included, comprising five randomized controlled trials and three quasi-experimental studies. Music interventions consisted of live music, recorded music, and active music, with a variety of music styles and genres. Despite the small and short-term effects, five studies presented significantly positive outcomes for reducing chronic pain and its common comorbidities in older adults following music interventions. Three studies reported decreased trends in pain scores although they did not reach statistical significance. CONCLUSIONS: Music has potential to be an effective adjuvant for managing chronic pain in older adults. CLINICAL RELEVANCE: Nurses can incorporate music into the care of older adults with chronic pain.

Effects of Vitality Acupunch exercise on functional fitness and activities of daily living among probable sarcopenic older adults in residential facilities.

PURPOSE: To test the effects of a Vitality Acupunch exercise program on the functional fitness and the ability to perform the activities of daily living (ADL) among older adults with probable sarcopenia in residential facilities. DESIGN: This was a cluster-randomized controlled trial. A total of 12 long-term care facilities randomly assigned to the intervention and control groups with 1:1 allocation ratio. Among them, 114 older adults with probable sarcopenia participated at baseline and were allocated to either the intervention or control group according to the facility where they resided in. Of these, 103 older adults completed the study. METHODS: The intervention group (n = 52) underwent the Vitality Acupunch exercise program three times a week, each lasting 40 min, for 6 months while the control group (n = 51) performed its routine daily activities. FINDINGS: The functional fitness and ADL of the intervention group significantly improved at each time point (all p < 0.001), while the control group showed a significant decreasing trend. Except the lower limb muscular endurance, the functional fitness and ADL of the intervention group significantly improved compared to the control group at T1, and the improvements were still significant at T2. CONCLUSIONS: Functional fitness and the ability to perform ADL in older adults with probable sarcopenia were significantly improved after receiving the Vitality Acupunch exercises. CLINICAL RELEVANCE: An exercise that integrates the meridian theory and exercise concepts effectively improves functional fitness in probable sarcopenic older adults. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov (NCT04504786). The trial was first posted on August 7, 2020. This part of the data was collected from August 2020 to March 2021.

[Role Function and Policy Prospects of Long-Term Care Nurses in Taiwan: Evidence-Based Policy Recommendations of Professional Nursing Organizations].

Professional nursing organizations represent an important channel for the nursing profession to influence health policy, represent and protect the interests of nurses, and advocate for the further development of the profession. Facing the rapidly increasing aging population and emerging needs of long-term care in Taiwan, the Taiwan Nurses Association launched an integrated project to propose policy advice on the development of nursing in long-term care. In this paper, the relevant findings in the domestic and foreign literature are summarized to better define the role function and core competence of long-term care nurses. In addition, the current tasks, perceived competence, and training needs of nurses working in long term care settings are presented, and the consensus on various advocacy strategies are summarized. The findings presented in this study may be referenced when developing evidence-based policy recommendations related to education, practice, legal / regulatory amendments, and professional organizations.

The individualized supervision strategy and effectiveness under the strength perspective: a pilot study for the case management model of the high-care elderly in communities.

BACKGROUND: This study tried to improve the operational efficiency and service quality of the community case management model for the High-Care Elderly in Communities in Taiwan. This study tried to assistant social workers in community care sites to establish individualized treatment planning, to empower them with flexibility to discover and utilize their own unique strengths, to reach the goal of developing community care capacity. METHODS: A case consulting model was employed in this study by providing case by case supervision service. We collected all supervision meeting records and related data as our qualitative research materials, analyzed these materials and tried to define intervention effectiveness of the individualized supervision strategy under the strength perspective applied to the case management model of the high-care elderly in communities. To find out what helps these social workers the most, and how these social workers realize and recognize their process and key to improve their service quality and work efficiency, in the way of qualitative interpretation. RESULTS: A supervision model under the perspective of strength was developed in this study, and was applied to clinical community care sites to help their social workers. The results proved that our supervision model provided an opportunity to empower and re-know themselves, re-establish their professional confidence and meaning of existence for their organization, and eventually produced positive effect to quality of service and service receiver's satisfaction improvement. The key feature that made this supervision model of the strength perspective work was to let social workers have the autonomy to interpret the challenges they face and to think possible alternative solutions creatively. CONCLUSIONS: This study showed that create a supervisee-friendly psycho-socio environment empowered these workers by increasing their resource network and taking advantage of what they still have and what they were good at, this could help these workers upgrade their level on ladders of empowerment, become an active and independent professional worker that have power and confidence to make treatment and intervention.

Polypharmacy and pattern of medication use in community-dwelling older adults: A systematic review.

AIM: To synthesise current study findings on the diseases and the corresponding medications that are potentially associated with polypharmacy in community-dwelling older adults. BACKGROUND: Polypharmacy is receiving increased attention as a potential problem for the older population. Although several scientific investigations have studied polypharmacy, most of them were carried out in long-term care facilities or mixed settings rather than in community settings solely. METHODS: This systematic review followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Relevant studies published in the English language in peer-reviewed journals were identified from searches of seven electronic databases for the period of January 2000 through December 2019. Inclusion criteria were: (1) Participants were older adults aged 65 years and older; (2) Polypharmacy was defined by medication count; (3) Medication classes associated with polypharmacy were revealed; (4) Studies were conducted in outpatient care or community settings. The Joanna Briggs Institute critical appraisal checklists for cross-sectional studies and for cohort studies were used to assess the methodological quality. RESULTS: Ten studies were considered having appropriate and acceptable quality to be reviewed, comprising nine cross-sectional studies and one cohort study. Polypharmacy was most defined as concurrently using five or more medications. Polypharmacy prevalence ranged between 7%-45%. Older age, comorbidity, poor self-perceived health status, limitations in physical activity, history of falls, depression, and pain were positively associated with polypharmacy. The most prevalent medication taken by older adults with polypharmacy was cardiovascular drugs. CONCLUSIONS: The prevalence of polypharmacy in older adults varying widely may be due to geographical locations, clinical practice guidelines, and polypharmacy definition used. RELEVANCE TO CLINICAL PRACTICE: Validated measurements to investigate medications associated with polypharmacy are required. How polypharmacy develops over time needs to be investigated in longitudinal studies in order to formulate strategies for reducing polypharmacy.

Information technology on hand hygiene compliance among health care professionals: A systematic review and meta-analysis.

AIM: To determine the effectiveness of information technology interventions on hand hygiene compliance among health care professionals. BACKGROUND: Performing hand hygiene is the optimal approach to prevent the transmission of health care-associated infections. However, results regarding the effectiveness of information technology interventions on hand hygiene compliance were inconsistent to date. EVALUATION: A search for studies published up to May 2020 was undertaken. A meta-analysis was conducted using RevMan 5.3 software. KEY ISSUES: The most commonly used information technology systems were as follows: automated training, electronic counting devices and remote monitoring, real-time hand hygiene reminders and feedback, and automated monitoring. These four types of technology systems can significantly improve hand hygiene compliance among health care professionals (odds ratio = 3.06, p < .001). CONCLUSION: The four types of information technology can be effectively used to change the hand hygiene behaviour. Because the information systems can monitor personnel and conduct statistical analyses automatically, they save labour costs of human monitors, are more time efficient and eliminate accompanying human error. IMPLICATIONS FOR NURSING MANAGEMENT: The use of the four types of information technology is convenient and could reduce health care-associated infections; thus, they could be widely used in the future as the key to increase hand hygiene compliance rate.

Cardiopulmonary Endurance of Hospitalized Older Adults With Chronic Obstructive Pulmonary Disease.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) could lead to poor cardiopulmonary endurance, which affects quality of life and increases the risk of rehospitalization or mortality. However, studies investigating associated factors of cardiopulmonary endurance for COPD inpatients are scant. OBJECTIVE: The aim of the study was to investigate whether and how age, gender, COPD severity, body composition, dyspnea, respiratory muscle strength, and lower limb muscle strength and endurance were related to cardiopulmonary endurance in elderly inpatients with COPD. METHODS: This was a cross-sectional study using a systematic sampling of older inpatients. Data of demographic characteristics such as age, gender, and disease severity were collected, and body mass index was calculated. Degrees of dyspnea were assessed by the modified Medical Research Council Dyspnea Scale. Respiratory muscle strength was reflected by the maximal inspiratory pressure and the maximal expiratory pressure. Lower limb muscle strength and endurance were assessed by a handheld dynamometer and a 30-second sit-to-stand test, respectively. Finally, cardiopulmonary endurance was assessed by a 6-minute walk test. RESULTS: A total of 83 older COPD inpatients participated. The mean age was 74.01 ± 6.93 years. Cardiopulmonary endurance was associated with age, COPD severity, dyspnea, respiratory muscle strength, lower limb muscle strength, and endurance. Predictors of cardiopulmonary endurance were disease severity, dyspnea, and lower limb muscle endurance. These predictors explained 53% of the variance in cardiopulmonary endurance in older inpatients with COPD. DISCUSSION: Cardiopulmonary endurance of hospitalized older adults with COPD should be strengthened by improving conditions of disease severity, dyspnea, and lower limb muscle endurance.

Development of a Screening Scale for Community-dwelling Older Adults with Multiple Care Needs.

Objectives: To develop a screening scale for community-dwelling older adults with multiple care needs.Methods: A modified Delphi was employed; 10 experts were invited to evaluate the relevancy, clarity, and suitability of the scale. A descriptive evaluation survey was tested on the screening scale users who were community volunteers to evaluate the clarity, relevance, and usefulness of the scale using a 10-point rating system. Confirmatory factor analysis was applied to determine the suitability of the factorial structure of the HCOASS. The internal consistency was examined using Kuder-Richardson Formula 20. A suitable cutoff point was developed using receiver operating characteristic analysis.Results: In the first round of the modified Delphi, the item-level content validity index (I-CVI) on the content relevance, item clarity, and suitability of the scale were all higher than .90, .80, and .80, respectively. In the second round, the scores for content relevancy, item clarity, and suitability were all 1.0. Community volunteers rated highly on the scale. The result of the confirmatory factor analysis indicated a good fit. The internal consistency reliability was satisfactory. The area under curve (AUC), sensitivity, and specificity for cutoff score of 6/7 were .91, 88%, and 81%, respectively.Conclusions: The screening scale demonstrated adequate reliability, content validity, and discriminant validity.Clinical Implications: The screening scale would serve as a reference for community volunteers in the identification of community-dwelling older adults with multiple care needs.

Development of a Care Delivery Model for High-Need Older Adults in the Community.

BACKGROUND: High-need older adults have multiple needs and require different types of care services. Care coordinators in community care centers in Taiwan, however, often experience difficulties in providing sufficient care services because of the inadequate capacity of case management. OBJECTIVE: The aim of this study was to develop a realistic care delivery model for the care coordinators to manage the care of high-need, community-dwelling older adults. METHODS: Focus-group interviews concerning elements and process for establishing a care delivery model were conducted with 12 care management experts in two groups: the practical work group (three registered nurses and three social workers) and the care management group (three care managers and three care management supervisors). The interviews were video-recorded and subjected to content analysis. RESULTS: A five-stage care delivery model was formulated: case screening, case assessment, care plan, care delivery, and follow-up evaluation. Six types of high-need older adults were identified: those living with disability, solitude, dementia, depression, elder abuse, and poverty. A list of categorized care services, including care resources, social welfare resources, and caregiver resources, was then used as a guide for case management and care delivery. DISCUSSION: The developed model-consisting a classification of services for different types of high-need older adults-serves as a guide for care coordinators in community care centers to make better decisions on service linkages, resource management, and care plan monitoring.

Modelling factors of urinary incontinence in institutional older adults with dementia.

AIMS AND OBJECTIVES: This study applied structural equation modelling to explore the relationships among agitated behaviours, depression, cognitive function and activities of daily living, as well as associations between these factors and urinary incontinence). BACKGROUND: A high prevalence of urinary incontinence is found among institutional older adults with dementia. People with urinary incontinence suffer from increased financial burden and social isolation and experience reduced quality of life. DESIGN: Cross-sectional correlational research. The study complied with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. METHODS: In total, 226 older adults with dementia were recruited through convenience sampling at 15 long-term care facilities in southern Taiwan. The urinary incontinence frequency, agitated behaviours, depression, cognitive function and activities of daily living were evaluated using bladder records, the Cohen-Mansfield Agitation Inventory, the Cornell Scale for Depression in Dementia, the Mini-Mental State Examination and the Barthel Index, respectively. RESULTS: Activities of daily living performance was found to be significantly associated with urinary incontinence; however, age, cognitive function, depression and agitated behaviours were not significantly related to urinary incontinence. Age did not have effects on any of the variables tested in this model, whereas activities of daily living performance was significantly associated with cognitive function and depression. Results further showed that cognitive function and depression were mediators between activities of daily living and agitated behaviours. CONCLUSION: Enhanced activities of daily living independency directly reduced urinary incontinence, improved cognitive function, decreased degrees of depression and indirectly reduced agitated behaviours. RELEVANCE TO CLINICAL PRACTICE: The findings could serve as a valuable reference for long-term care facilities in providing effective urinary incontinence care and prevention to older adults with dementia.

Self-Perceived Health and Sleep Quality of Community Older Adults after Acupunch Exercises.

OBJECTIVES: To test the long-term effects of the 12-month Healthy Beat Acupunch (HBA) exercise program on the self-perceived health and sleep quality of older adults in community care centers, and to compare the effects of two delivery methods: instructor-led HBA for the first 6 months and DVD-guided HBA for another 6 months. DESIGN: Cluster-randomized controlled trial. SETTING: Eight community care centers. PARTICIPANTS: In total, 232 participants were recruited from eight community care centers, and cluster-randomized to the experimental (4 centers, N = 113) and control (4 centers, N = 119) groups. INTERVENTION: The experimental group received the instructor-led HBA program 3 times weekly for the first 6 months, followed by the DVD-guided HBA program for another 6 months. MEASUREMENTS: Self-perceived health and sleep quality were assessed using the Short Form Health Survey and the Pittsburgh Sleep Quality Index, respectively, at baseline and every 3 months for 1 year. RESULTS: The experimental group reported more favorable self-perceived physical and mental health, higher subjective sleep quality, and less daytime dysfunction than did the control group. Effect sizes of physical health and sleep quality increased from the instructor-led stage to the DVD-guided stage; the effect size of physical health showed the most significant change, increasing from 0.38 in the instructor-led stage to 0.55 in the DVD-guided stage. CONCLUSIONS: The exercise program consisting of the instructor-led class, followed by the DVD-guided class, was an effective and feasible longitudinal program for older adults in community care centers.

Physical and mental health status and their correlations among older wheelchair users with dementia in long-term care facilities.

PURPOSE: To investigate the physical health (daily functioning and functional fitness) and mental health (depression and behavioral dysfunction) of older wheelchair users with dementia in long-term care facilities, examine the correlations between physical and mental health, and identify the independent variables of their daily functioning. METHODS: A descriptive correlational method was adopted, which was conducted in six long-term care facilities in three cities, south Taiwan. Participants comprised 98 older wheelchair users with dementia. Data were collected using structured questionnaires (Mini-Mental State Examination, Barthel Index, Cornell Scale for Depression in Dementia, and Clifton Assessment Procedures for the Elderly Behavior Rating Scale) and from functional fitness testing (cardiopulmonary functioning, body flexibility, joint mobility, and muscle strength and endurance). RESULTS: Older adults with dementia who had high depression scores were likely to have more behavioral dysfunctions, poorer performance in shoulder flexion and abduction, and lower upper limb muscle strength and endurance. More behavioral dysfunctions were associated with poorer daily functioning, lung capacity, body flexibility, shoulder flexion, and upper limb muscle strength and endurance. Those with better lung capacity, body flexibility, upper limb muscle strength, and endurance were likely to have high daily functioning scores (all p < .05). The key independent variables associated with daily functioning were behavioral dysfunction, lower body flexibility, and lung capacity, which together explained 59.3% of the total variance. CONCLUSIONS: Further research should develop appropriate activity-based intervention programs for older wheelchair users with dementia to delay their deterioration and promote their physical and mental health.
