Dance for People with Alzheimer's Disease: A Systematic Review

More Than Just Movement: Exploring Embodied Group Synchrony During Seated Dance for Older Adults Living in Residential Aged Care Communities

One in six people in Australia are aged over 65, with many older adults currently living in residential aged care communities (RACC). Fostering meaningful human connection through social activities, such as dance, is imperative to maintain or improve the quality of life in these settings. Drawing from an embodied cognition framework, this mixed-methods study explored synchrony during a seated dance program with 15 older adults living in a RACC. Qualitative video content analysis was used to code movement, language and music cooccurrences, resulting in five group synchrony labels. Hierarchical Cluster Analysis (HCA) was then employed to distil ten higher-order forms of embodied group synchrony. Using existing neurocognitive evidence, we detail the therapeutic and interpersonal implications of the most prominent forms of embodied group synchrony. These findings can be used to choreograph therapeutic forms of embodied group synchrony in dance programs with older adults.

Impact of dance interventions on the symptoms of dementia: A mixed-methods systematic review

OBJECTIVES

This mixed-methods systematic review determined the impact of dance interventions on symptoms of Alzheimer's disease and related dementias (ADRD) among persons living in residential care.

METHODS

Seven databases (Medline, EMBASE, CINAHL, PsycINFO, Web of Science, Ageline, and AMED) were searched. Studies published before June 2022 that investigated the impact of dance interventions on symptoms of ADRD were eligible for inclusion. Risk of bias was assessed using CASP, ROBINS-I, and ROB-2. Quantitative and qualitative objectives provided a convergent segregate narrative synthesis for the review. The review protocol was registered on PROSPERO (CRD42021220535).

RESULTS

Two quantitative and two qualitative studies met the inclusion criteria. Dance interventions decreased levels of agitation and aggression, and improved behavioural and psychological symptoms.

CONCLUSIONS

Studies suggest that dance interventions reduce the symptoms of dementia through increased expression, emotions, and improved relationships for persons with ADRD. However, the small number of included studies limits these conclusions.

"It doesn't feel like exercise": a realist process evaluation of factors that support long-term attendance at dance classes designed for healthy ageing

Introduction

Dance can positively impact older people's health and wellbeing across cultures and socioeconomic groups, countering age-related physical, sensorimotor and cognitive decline.

Background/objectives

The RIPE (Really Is Possible for Everyone) Dance program aims to improve older people's physical, mental, cognitive and social wellbeing by integrating engaging dance sequences with evidence-based fall prevention exercises. We sought to identify what mechanisms support observed long-term participation in this program, including by people living with challenging health conditions.

Methods

Following a realist evaluation approach, we co-developed and tested program theories iteratively with participant interviewees (n = 20), dance teachers (n = 2) and via observation of a dance class. Initial data were dual-coded and emergent findings were interrogated by the research team. Findings were organised to express Program activities + Context + Mechanism = Process outcomes configurations.

Results

We identified four program theories comprising 14 mechanisms which explained long-term attendance: 1. RIPE Dance benefits my body and mind (trust in the program, belief in health benefits), 2. RIPE Dance helps me feel good about myself (self-efficacy, pride in achievement, psychological safety, defying expectations, feeling valued), 3. RIPE Dance creates camaraderie (social connection, mutual support, rapport with the teacher), and 4. RIPE Dance is uplifting (raised spirits, fun, synchrony, musical reactivity).

Conclusion

The RIPE Dance program provides effective and enjoyable 'exercise in disguise' for older people with diverse mobility profiles.

Significance/implications

This research confirms that participation in dance can contribute significantly to healthy, happy ageing. Findings detail program activities that were most strongly associated with process outcomes, offering guidance for further program development, implementation and scaling up.

Topical Cellular/Tissue and Molecular Aspects Regarding Nonpharmacological Interventions in Alzheimer's Disease-A Systematic Review

One of the most complex and challenging developments at the beginning of the third millennium is the alarming increase in demographic aging, mainly-but not exclusively-affecting developed countries. This reality results in one of the harsh medical, social, and economic consequences: the continuously increasing number of people with dementia, including Alzheimer's disease (AD), which accounts for up to 80% of all such types of pathology. Its large and progressive disabling potential, which eventually leads to death, therefore represents an important public health matter, especially because there is no known cure for this disease. Consequently, periodic reappraisals of different therapeutic possibilities are necessary. For this purpose, we conducted this systematic literature review investigating nonpharmacological interventions for AD, including their currently known cellular and molecular action bases. This endeavor was based on the PRISMA method, by which we selected 116 eligible articles published during the last year. Because of the unfortunate lack of effective treatments for AD, it is necessary to enhance efforts toward identifying and improving various therapeutic and rehabilitative approaches, as well as related prophylactic measures.

High-intensity walking in midlife is associated with improved memory in physically capable older adults

BACKGROUND

Little is known about the associations of midlife- and late life-initiated walking with Alzheimer's disease (AD)-related cognitive decline in humans. We aimed to investigate whether high-intensity, prolonged, midlife-initiated walking is associated with changes in AD-related cognitive decline in physically capable older adults.

METHODS

We studied 188 physically capable participants aged 65-90 years without dementia who underwent comprehensive clinical assessment, including of their walking modality (i.e., intensity, duration, midlife- or late life-onset), memory- or non-memory and total cognitive performance, and blood or nutritional biomarkers.

RESULTS

The walking group showed better episodic memory (B = 2.852, SE = 1.214, β = 0.144, p = 0.020), but not non-memory cognition, than the non-walking group. High-intensity walking starting in midlife was significantly associated with better episodic memory (B = 9.360, SE = 3.314, β = 0.446, p = 0.005) compared to the non-walking group. In contrast, there were no differences in cognition according to walking duration, regardless of the onset time. The walking group also showed a similar association with overall cognition.

CONCLUSIONS

Among physically capable older adults without dementia, walking, particularly at high intensity and starting in midlife, is associated with improved episodic memory, an AD-related cognitive domain. Further attention should be paid to the role of walking in terms of AD prevention.

Dance movement therapy for dementia

BACKGROUND

Dementia is a syndrome of acquired cognitive impairment which is severe enough to interfere with independent living. Over the course of the illness, people with dementia also experience changes in emotions, behaviour and social relationships. According to Alzheimer's Disease International, dementia affects approximately 55 million people worldwide. The latest NICE guideline for dementia highlights the value of diverse treatment options for the different stages and symptoms of dementia, including non-pharmacological treatments. Relevant literature also argues for the value of interventions that acknowledge the complexity of the condition and address the person as a whole, including their physical, emotional, social and cognitive processes. A growing literature highlights the capacity of the arts and has embodied practices to address this complexity. Dance movement therapy (DMT) is an embodied psychological intervention that can address complexity and thus may be useful for people with dementia, but its effectiveness remains unclear.

OBJECTIVES

To assess the effects of dance movement therapy on behavioural, social, cognitive and emotional symptoms of people with dementia in comparison to no treatment, standard care or any other treatment. Also, to compare different forms of dance movement therapy (e.g. Laban-based dance movement therapy, Chacian dance movement therapy or Authentic Movement) SEARCH METHODS: We searched the Cochrane Dementia and Cognitive Improvement Group's register, MEDLINE (Ovid SP), Embase (Ovid SP), PsycINFO (Ovid SP), CINAHL (EBSCOhost), Web of Science Core Collection (Clarivate), LILACS (BIREME), ClinicalTrials.gov and the World Health Organization's meta-register of the International Clinical Trials Registry Portal until 8 December 2022.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that included people with dementia, of any age and in any setting. The DMT intervention had to be delivered by a dance movement therapy practitioner who (i) had received formal training (ii) was a dance movement therapist in training or (iii) was otherwise recognised as a dance movement therapist in the country in which the study was conducted.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion, extracted data and evaluated methodological quality. We expressed effect estimates using the mean difference (MD) between intervention groups and presented associated confidence intervals (CIs). We used GRADE methods to rate our certainty in the results.

MAIN RESULTS

We found only one study eligible for inclusion in this review. This was a 3-arm parallel-group RCT conducted in Hong Kong involving 204 adults with mild neurocognitive disorder or dementia. The study examined the effects of short-term (12 weeks) group DMT in comparison with exercise and a waiting-list control group immediately post-intervention and three and nine months later. We found that, at the end of the intervention, DMT may result in little to no difference in neuropsychiatric symptoms assessed with the 12-item Neuropsychiatric Inventory when compared with waiting list (MD 0.3, 95% CI -0.96 to 1.56; low-certainty evidence) or exercise (MD -0.30, 95% CI -1.83 to 1.23; low-certainty evidence). Nor was there any evidence of effects at later time points. Cognitive functioning was assessed with a variety of instruments and there were no statistically significant between-group differences (low-certainty evidence). When compared to exercise or waiting list, DMT may result in little to no difference in cognitive function immediately after the intervention or at follow-up. In comparison to waiting list, DMT may result in a slight reduction in depression assessed with the 4-item Geriatric Depression Scale at the end of therapy (MD -0.60, 95% CI -0.96 to -0.24; low-certainty evidence). This slight positive effect of DMT on depression scores was sustained at three and nine months after the completion of the intervention. DMT may also reduce depression slightly in comparison with exercise at the end of therapy (MD -0.40, 95% CI -0.76 to -0.04, low-certainty evidence), an effect also sustained at three and nine months. Our fourth primary outcome, quality of life, was not assessed in the included study. There were data for two of our secondary outcomes, social and occupational functioning and dropouts (which we used as a proxy for acceptability), but in both cases the evidence was of very low certainty and hence our confidence in the results was very low. For all outcomes, we considered the certainty of the evidence in relation to our review objectives to be low or very low in GRADE terms due to indirectness (because not all participants in the included study had a diagnosis of dementia) and imprecision.

AUTHORS' CONCLUSIONS

This review included one RCT with a low risk of bias. Due to the low certainty of the evidence, the true effects of DMT as an intervention for dementia may be substantially different from those found. More RCTs are needed to determine with any confidence whether DMT has beneficial effects on dementia.

Association between physical activity and episodic memory and the moderating effects of the apolipoprotein E ε4 allele and age

Background

An abundance of evidence indicates that physical activity may protect against Alzheimer's disease (AD) and related cognitive decline. However, little is known about the association between physical activity and AD-related cognitive decline according to age and the apolipoprotein E (APOE) ε4 allele (APOE4) as major risk factors. Therefore, we examined whether age and APOE4 status modulate the effects of physical activity on episodic memory as AD-related cognition in non-demented older adults.

Methods

We enrolled 196 adults aged between 65 and 90 years, with no dementia. All participants underwent comprehensive clinical assessments including physical activity evaluation and APOE genotyping. The AD-related cognitive domain was assessed by the episodic memory, as the earliest cognitive change in AD, and non-memory cognition for comparative purposes. Overall cognition was assessed by the total score (TS) of the Consortium to Establish a Registry for Alzheimer's Disease neuropsychological battery.

Results

We found significant physical activity × age and physical activity × APOE4 interaction effects on episodic memory. Subgroup analyses indicated that an association between physical activity and increased episodic memory was apparent only in subjects aged > 70 years, and in APOE4-positive subjects.

Conclusion

Our findings suggest that physical activity has beneficial effects on episodic memory, as an AD-related cognitive domain, in individuals aged > 70 years and in APOE4-positive individuals. Physicians should take age and APOE4 status account into when recommending physical activity to prevent AD-related cognitive decline.

Dance-Specific Activity in People Living With Dementia: A Conceptual Framework and Systematic Review of Its Effects on Neuropsychiatric Symptoms

OBJECTIVES

Dance as a non-pharmacological therapy is commonly used in dementia care, although the evidence of its effects remains unclear. This study systematically reviewed the effects of dance interventions on neuropsychiatric symptoms (NPS) in people living with dementia. To systematically identify and evaluate dance interventions, a standardized terminology for Dance-Specific Activity (DSA) is proposed.

METHODS

Literature search was conducted on electronic databases until April 30th 2021. Studies were included when they quantified the effects of DSA on NPS in people with clinical diagnosis of dementia. Included studies were analyzed in detail for NPS. Study quality was assessed by PEDro scale (German version).

RESULTS

4 studies were included. The studies differed in study design, intervention protocols, dance styles, or measurement tools, and were generally of low study quality. Two trials showed improvements in NPS and 2 trials showed no exacerbation of NPS after DSA.

CONCLUSIONS

The results of the 4 available trials indicate a positive tendency towards the effects of DSA, but considering the limitations of the few available studies, a clear statement about the effects of DSA is not possible yet. Based on the included trials, the following implications for clinical research and routine care can be derived: (1) DSA seems to be a practical terminology for identifying dance interventions (2) DSA seems to be a safe intervention for people living with dementia. (3) Different dance styles can be used. (4) DSA approaches should be better structured by differentiating between the domains type, content, intention, and protocol of the intervention.

Nerve Transfers for Brachial Plexus Reconstruction in Patients over 60 Years

Negative expectations regarding nerve reconstruction in the elderly prevail in the literature, but little is known about the effectiveness of nerve transfers in patients with brachial plexus injuries aged over 60 years. We present a series of five patients (1 female, 4 male) aged between 60 and 81 years (median 62.0 years) who underwent nerve reconstruction using multiple nerve transfers in brachial plexopathies. The etiology of brachial plexus injury was trauma (n = 2), or iatrogenic, secondary to spinal surgical laminectomy, tumor excision and radiation for breast cancer (n = 3). All but one patient underwent a one-stage reconstruction including neurolysis and extra-anatomical nerve transfer alone (n = 2) or combined with anatomical reconstruction by sural nerve grafts (n = 2). One patient underwent a two-stage reconstruction, which involved a first stage anatomical brachial plexus reconstruction followed by a second stage nerve transfer. Neurotizations were performed as double (n = 3), triple (n = 1) or quadruple (n = 1) nerve or fascicular transfers. Overall, at least one year postoperatively, successful results, characterized by a muscle strength of M3 or more, were restored in all cases, two patients even achieving M4 grading in the elbow flexion. This patient series challenges the widely held dogma that brachial plexus reconstruction in older patients will produce poor outcomes. Distal nerve transfers are advantageous as they shorten the reinnervation distance. Healthy, more elderly patients should be judiciously offered the whole spectrum of reconstructive methods and postoperative rehabilitation concepts to regain useful arm and hand function and thus preserve independence after a traumatic or nontraumatic brachial plexus injury.

Therapeutic approaches for improving cognitive function in the aging brain

The rapid aging of populations around the world has become an unprecedented challenge. Aging is associated with cognitive impairment, including dementia and mild cognitive impairment. Successful drug development for improving or maintaining cognition in the elderly is critically important. Although 4 drugs for improving cognition in Alzheimer's disease have been approved, a variety of potential drugs targeting age-related cognitive impairment are still in development. In addition, non-pharmacological interventions, including cognition-oriented treatments, non-invasive brain stimulation physical exercise, and lifestyle-related interventions, have also been suggested as cognitive enhancers in the last decade. In this paper, we reviewed the recent evidence of pharmacological and non-pharmacological interventions aimed at improving or maintaining cognition in the elderly.

Moving online: Experiences and potential benefits of digital dance for older adults and people with Parkinson's disease

BACKGROUND

Dance provides a range of beneficial effects for older adults including individuals with age-related neurological conditions such as Parkinson's disease (PD). The COVID-19 pandemic accelerated the development of at-home dance programs delivered digitally through live and pre-recorded media, but little is known about how participants may engage with and benefit from these resources.

OBJECTIVE

This study explored experiences and potential benefits of digital dance participation among healthy older adults and people with PD.

METHODS

An online survey consisting of fixed-choice and open questions was designed in collaboration with dance program providers and distributed between June and November 2020.

RESULTS

Healthy older adults (N = 149) and people with PD (N = 178) participating in at-home dance programs reported frequent engagement and a range of benefits. People with PD reported greater levels of motor (e.g., ease of movement, balance) than non-motor (e.g., energy, confidence) outcomes, while healthy older adults reported similar numbers of motor and non-motor outcomes. Positive outcomes were associated with the use of movement imagery during dance in both groups, while singing was associated with benefits in people with PD and vocalising was associated with benefits in older adults. At-home dance resources were found to offer convenience and flexibility, but participants missed the interaction, support, and routine provided by in-person classes. The majority expressed a preference to continue with both digital and in-person participation in the future. Qualitative analysis of participants' comments further revealed that digital participation could help to maintain connection and well-being, as well as identifying further considerations for improving accessibility and facilitating digital engagement.

CONCLUSIONS

At-home dance appears to be accessible, engaging, and potentially beneficial for older adults and people with PD, although barriers to participation should be addressed. Digital resources will be increasingly important to enable cost-effective, large-scale provision of home-based therapeutic activities.

Dance movement therapy for neurodegenerative diseases: A systematic review

Background

The proportion of the world's elderly population continues to rise, and the treatment and improvement of neurodegenerative diseases have become issue of public health importance as people live longer and many countries have aging populations. This systematic review aims to discuss the effects of dance movement therapy (DMT) on motor function, cognitive deficit, mood, and quality of life in people with neurodegenerative diseases, such as Parkinson's disease (PD), mild cognitive impairment (MCI), Alzheimer's disease (AD).

Methods

Two reviewers independently conducted systematic search on the Cochrane library, PubMed database, Web of Science Core Collection database, and Physiotherapy Evidence database until February 1, 2022. Only systematic analyses and randomized controlled trials were included and further analyzed.

Results

Thirty-three studies on PD, 16 studies on MCI, 4 studies on AD were obtained. This systematic review found that DMT substantially improved the global cognitive function, memory, and executive function on the population with MCI. Compared with the non-dance group, DMT remarkably improved general disease condition, balance, and gait for individuals with PD. The evidence of the efficacy of DMT on AD is insufficient, and further research is needed.

Conclusion

DMT can effectively improve the motor function and cognitive deficits in neurodegenerative diseases. Positive effects of DMT on the mood and quality of life in ND patients are controversial and require further evidence. Future research on the effects of DMT on AD requires scientific design, large sample size, long-term comprehensive intervention, and clear reporting standards.

Dance therapy and cognitive impairment in older people: A review of clinical data

ABSTRACT The growing interest for nonpharmacological treatment alternatives to older people with mild cognitive impairment or dementia has increased exponentially for the past few years; in this context, dance therapy is an effective therapeutic tool in improving the cognition of older people. The aim of this study was to verify whether dance therapy is a viable tool in promoting benefits with regard to the cognition and mood of older people with cognitive impairment. A database search covering the past 10 years was carried out. Result: The search found 193 papers; after title, abstract, and duplicity analysis, 14 of those were selected, of which 10 were fully revised. The studies showed positive results regarding the improvement of cognitive function after dance stimulations, as well as beneficial effects on the mood of older people with cognitive impairment.

Effects of interventions on cerebral perfusion in the Alzheimer's disease spectrum: A systematic review

Cerebral perfusion dysfunctions are seen in the early stages of Alzheimer's disease (AD). We systematically reviewed the literature to investigate the effect of pharmacological and non-pharmacological interventions on cerebral hemodynamics in randomized controlled trials involving AD patients or Mild Cognitive Impairment (MCI) due to AD. Studies involving other dementia types were excluded. Data was searched in April 2021 on MEDLINE, Embase, and Web of Science. Risk of bias was assessed using Cochrane Risk of Bias Tool. A meta-synthesis was performed separating results from MCI and AD studies. 31 studies were included and involved 310 MCI and 792 CE patients. The MCI studies (n = 8) included physical, cognitive, dietary, and pharmacological interventions. The AD studies (n = 23) included pharmacological, physical interventions, and phytotherapy. Cerebral perfusion was assessed with PET, ASL, Doppler, fNIRS, DSC-MRI, Xe-CT, and SPECT. Randomization and allocation concealment methods and subject characteristics such as AD-onset, education, and ethnicity were missing in several papers. Positive effects on hemodynamics were seen in 75 % of the MCI studies, and 52 % of the AD studies. Inserting cerebral perfusion outcome measures, together with established AD biomarkers, is fundamental to target all disease mechanisms and understand the role of cerebral perfusion in AD.

A Brief Report on Reviews of Existing Creative Art-Based Interventions in Dementia Care From 2010-2020

The following brief report provides an overview of previously published reviews in the context of creative arts-based interventions for persons with dementia. A total of 22 review articles were identified and summarized. Next steps are suggested for future studies that may wish to a) develop a new review, or b) create new studies filling in the gaps identified by the authors in this report.

Application of Educational Psychology-Based Dance Therapy in College Students' Life Education

The purpose is to strengthen the life education of contemporary college students and give better play to the vital role of life education in preventing college students' mental diseases. Specifically, it discusses the role of dance therapy (DT) in College Students' Life Education (CSLE). Firstly, based on educational psychology (EP), this manuscript analyzes the relevant theoretical concepts of EP and life education and discusses the importance of life education to contemporary college students. Secondly, following a Questionnaire Survey (QS) and using deep learning (DL) Convolutional Neural Network (CNN) and Facial Emotion Recognition (FER), this manuscript reviews and examines the CSLE's current situation and the DT effect. Research findings are summarized combined with the QS results and scores of 20 subjects before and after five activities in 3 months. (I) After DT intervention, the positive dimensions of college students' life values have improved, especially self-development and dedication, and their quality of life is refined. Thus, DT group counseling proves the positive role of DT in CSLE. (II) After DT intervention, 96.5% of the members think DT is effective. Therefore, EP-based DT is more effective and scientific in CSLE. The research findings provide a DT-based teaching concept for CSLE, explore the feasibility and effectiveness of life education, and enrich the DT scheme of CSLE. The research provides a practical reference for further applying DT in college students' psychological education.

Effects of fundamental movement skills based dual-task and dance training on single- and dual-task walking performance in older women with dementia

OBJECTIVE

The purpose of this study was to compare the effects of fundamental movement skills (FMS)-based dual-task training and dance training on spatio-temporal characteristics of gait performance under single- and dual-task walking conditions among older women with dementia.

METHOD

Thirty-eight elderly females with dementia were randomly assigned to one of two groups: (1) dual-task intervention (DTI, age: 73 ± 6.5 years) or (2) Iranian dance intervention (IDI, age: 72.52 ± 6.01 years). Both groups participated in a 10-week intervention program (3 sessions per week, each lasting 50 min). Gait performance parameters (gait speed, cadence, and stride length) and dual-task costs (DTC) were examined using a gait analysis system. The participants completed three walking trials under two conditions: single- and dual-task. The video data was analyzed using motion analysis software (Frame-DIAS II, DKH, DKH Inc., Tokyo, Japan).

RESULTS

The results showed that both groups significantly improved in terms of all gait variables, and DTC decreased (p < .001) from pre- to post-test for both conditions. However, the main effects for the group and the group-by-time interactions were not significantly different between the two groups (p > .05).

CONCLUSION

These findings showed that DTI and IDI effectively improved gait performance following a 10-week intervention for older women with dementia. Therefore, it is suggested that either training program could decrease DTC and increase gait speed, stride length, and cadence among older females with dementia.

Microbiome First Approaches to Rescue Public Health and Reduce Human Suffering

The is a sequential article to an initial review suggesting that Microbiome First medical approaches to human health and wellness could both aid the fight against noncommunicable diseases and conditions (NCDs) and help to usher in sustainable healthcare. This current review article specifically focuses on public health programs and initiatives and what has been termed by medical journals as a catastrophic record of recent failures. Included in the review is a discussion of the four priority behavioral modifications (food choices, cessation of two drugs of abuse, and exercise) advocated by the World Health Organization as the way to stop the ongoing NCD epidemic. The lack of public health focus on the majority of cells and genes in the human superorganism, the microbiome, is highlighted as is the "regulatory gap" failure to protect humans, particularly the young, from a series of mass population toxic exposures (e.g., asbestos, trichloroethylene, dioxin, polychlorinated biphenyls, triclosan, bisphenol A and other plasticizers, polyfluorinated compounds, herbicides, food emulsifiers, high fructose corn syrup, certain nanoparticles, endocrine disruptors, and obesogens). The combination of early life toxicity for the microbiome and connected human physiological systems (e.g., immune, neurological), plus a lack of attention to the importance of microbial rebiosis has facilitated rather than suppressed, the NCD epidemic. This review article concludes with a call to place the microbiome first and foremost in public health initiatives as a way to both rescue public health effectiveness and reduce the human suffering connected to comorbid NCDs.

Effects of dance intervention on agitation and cognitive functioning of people living with dementia in institutional care facilities: Systematic review

INTRODUCTION

Agitation and impaired cognitive functioning are common symptoms of dementia, which require costly medication regimens that are associated with adverse effects. This study investigates the effects of dance interventions on agitation and cognitive function in people living with dementia in institutional care facilities.

METHODS

Five electronic databases were searched for eligible studies on dance interventions for people living with dementia published between 2002 and 2021. Standard deviation and post mean values were extracted. Within-group Hedges' g was computed for individual studies.

RESULTS

Six randomised controlled trials and three non-randomised studies of satisfactory quality, with a total of 610 participants, were included. Statistical analysis found significant improvements in agitation and cognitive functioning with dance interventions.

DISCUSSION

This review provided favourable evidence on the effects of dance interventions on agitation and cognitive functions in people with dementia. However, given the limited evidence, more studies are needed to confirm the effects.

Effects of Exercise in the Treatment of Alzheimer's Disease: An Umbrella Review of Systematic Reviews and Meta-Analyses

The authors aimed to provide an overview of the evidence on the effects of exercise in people with Alzheimer's disease through a comprehensive review of the existing systematic reviews and meta-analyses. A literature search was performed in CINAHL, Cochrane Library, EMBASE, PubMed, SPORTDiscus, Scopus, and Web of Science databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The AMSTAR-2-Tool was used for the quality assessment. Twenty-three reviews fulfilled the criteria. Most of the reviews investigated the effects of aerobic exercise on Alzheimer's disease symptoms. The largest effects of exercise were seen in terms of improved cognition by multiple exercises. The majority of the reviews were rated as being of moderate quality and none were classified as having high quality. Exercise is an effective way to treat Alzheimer's disease symptoms and has a low incidence of related adverse events. As most reviews were evaluated as low-moderate quality, caution is needed in the interpretation of the results.

Effects of nurse-led square dancing on older patients with mild cognitive impairment combined with depressive symptoms: A pilot study

OBJECTIVE

The present study aimed to verify the feasibility and preliminary effects of nurse-led square dancing designed to improve older adults' cognitive function and depressive symptoms who with MCI.

METHODS

A quasi-experimental pilot study design was adopted for the present study. Screening for cognitive function was conducted among older adults (≥ 60 years old) living in two communities in Beijing who complained of memory loss. A total of 107 older patients with MCI and depressive symptoms were diagnosed after obtaining informed consent. Thirty-five patients selected from each community were included in the study as control and intervention groups, respectively. The two groups of patients received health education while the intervention group participated in a square dance intervention program led by nurses three times per week for 60 min per session over a period of three months. The Montreal Cognitive Assessment-Peking version (MoCA-P) and Geriatric Depression Scale (GDS-30) were used to assess the cognitive function and depressive symptoms of patients in the two groups at three time intervals; before intervention, at the end of the three-month intervention period, and over a three-month follow-up period after the end of intervention.

RESULTS

Feasibility of the intervention was established with a high completion rate of 90%. Data collection for 63 out of 70 patients enrolled for the study was completed after six months. MoCA-P and GDS-30 scores of the intervention group were significantly different after the intervention when compared with the control group. A significant improvement in cognition was observed in the intervention group, and depressive symptoms decreased after intervention and follow-up when compared with the control group. During the intervention and follow-up phases, the MoCA-P score of the intervention group increased gradually with time. Furthermore, the MoCA-P and GDS-30 scores of the control group remained unchanged.

CONCLUSION

This study has revealed that square dance intervention exerts a positive impact on cognitive function and depressive symptoms among older patients suffering from MCI and depressive symptoms. The results of this study support the feasibility and preliminary effects of square dancing on relieving cognitive decline and depressive symptoms. Square dancing is a recommended type of intervention that can be applied to the local Chinese population because of its simplicity, convenience, and suitability for the older adults.

Comparative Efficacy of Active Group Music Intervention versus Group Music Listening in Alzheimer's Disease

BACKGROUND

Music interventions are promising therapies for the management of symptoms in Alzheimer's disease (AD). Globally, music interventions can be classified as active or receptive depending on the participation of the subjects. Active and receptive music tasks engage different brain areas that might result in distinctive clinical effects. This study aims to compare the clinical effects of two types of music interventions and a control activity.

METHODS

Ninety AD patients from six nursing homes participated in the study. Nursing homes were randomly and blindly assigned to receive either active music intervention, receptive music intervention, or the usual care. Effects on cognition, behaviour, daily living activities, and motor function were assessed.

RESULTS

Active music intervention improved cognition, behaviour, and functional state in a higher extent than both receptive music intervention and usual care. The effect size of active music intervention for cognitive deficits and behavioural symptoms was large (η2 = 0.62 and 0.61, respectively), while for functional state, it was small-to-medium sized (η2 = 0.18). Receptive music intervention had a stabilizing effect on behavioural symptoms compared to control intervention (mean change from baseline ± standard deviation = -0.76 ± 3.66 and 3.35 ± 3.29, respectively). In the active music intervention, the percentage of patients who showed improvement in cognitive deficits (85.7), behavioural symptoms (92.9), and functional state (46.4) was higher than in both receptive listening (11.8, 42.9, and 14.3, respectively) and control group (6.3, 12.2, and 17.1, respectively).

CONCLUSIONS

Active music intervention is useful to improve symptoms of AD and should be prescribed as a complement to the usual treatment.

Effects of a multimodal exercise intervention on physical and cognitive functions in patients with chronic low back pain (MultiMove): study protocol for a randomized controlled trial

BACKGROUND

Chronic low back pain (CLBP) is a common medical condition in adults over the age of 50. It is associated with severe disability, ranging from physical impairments to psychosocial distress. Since current treatments provide only small to moderate short-term effects, alternative interventions are required, whereby guidelines recommended multimodal approaches. Dancing can be considered as an inherently multimodal approach, as it requires a combination of physical and cognitive functions. Furthermore, it has already been applied effectively in neurorehabilitation. Therefore, it seems promising to merge a dance-therapeutic component together with motor-cognitive, strength and flexibility exercises in a novel multimodal treatment (MultiMove) to target the impaired everyday mobility and cognition of CLBP patients. The aim of this study is to analyse specific physical, cognitive and psychosocial effects of MultiMove in CLBP patients.

METHODS

A prospective, two-arm, single-blinded, randomized controlled trial will be conducted with an estimated sample size of 100 CLBP patients, assigned to either the MultiMove group or a control group. The intervention group will receive MultiMove twice a week for 60 min each over a period of 12 weeks. The primary outcome will be the mobility and function of the lower extremities assessed by the Timed Up-and-Go Test. Secondary outcomes comprise further physical and physiological functions (e.g. gait variability and haemodynamic response in the prefrontal cortex during motor-cognitive dual tasks), subjective health state (e.g. disability in daily life), executive functions (e.g. cognitive flexibility) and psychosocial aspects (e.g. kinesiophobia). Measures will be taken at baseline, after the intervention and at a 12-week follow-up. It is assumed that MultiMove improves the mentioned outcome parameters.

DISCUSSION

The combined assessment of changes in physical and cognitive functions as well as neuropsychological aspects in response to MultiMove will allow a better understanding of the motor-cognitive adaptations induced by multimodal exercises in CLBP patients. The specific conclusions will lead to recommendations for the conservative treatment approach in this clinically relevant patient group.

DARE to move: feasibility study of a novel dance-based rehabilitation method in severe traumatic brain injury

Objective: Dance is a versatile and multimodal rehabilitation method, which may be useful also in traumatic brain injury (TBI) rehabilitation. Here, we assessed the feasibility and preliminary effects of a novel dance-based intervention called Dual-Assisted Dance Rehabilitation (DARE).Method: This is a feasibility study with a cross-over design where 11 persons with severe/extremely severe TBI received a 12-week (2 times/week) DARE program. Motor and neuropsychological tests and questionnaires measuring mood, executive functions, and quality of life were performed at baseline, 3-month, and 6-month stage. Self-perceived benefits were assessed with a post-intervention questionnaire.Results: Acceptability of and adherence to DARE were encouraging: 91% were fully consistent with protocol, and adherence to DARE sessions was 83-100%. Pre-post treatment effects sizes were medium-large for self-reported depression (BDI-II: d = 1.19-1.74) and executive deficits (BRIEF-A: d = 0.43-1.09) and for test-assessed trunk movement control (TIS: d = 0.47-0.76) and cognitive functioning (WAIS-IV subtests: d = 0.34-0.89). Other outcome measures did not show similar positive effect sizes. Self-perceived benefits were largest for mobility and cognition.Conclusion: Dance-based rehabilitation is a feasible and promising method in severe TBI and its efficacy should be assessed with a larger clinical trial.

A Pilot randomized clinical trial of adapted tango to improve cognition and psychosocial function in African American women with family history of Alzheimer's disease (ACT trial)

•

the adapted tango intervention was very well received as demonstrated by minimal participant attrition, satisfaction questionnaires that indicated high satisfaction, and anecdotal reports.

•

Adapted tango intervention may be helpful in controlling or reducing markers of inflammation in AA women with a parental history of AD.

•

Participants in tango demonstrated improvements in whole-body spatial cognition and short-term and working memory, and reduced deterioration of executive function.

•

Although our tango group did not show large positive effect in cumulative caregiver burden post intervention, the large positive effect in role Captivity, caregiver confidence, and deprivation of intimate exchange displays some of the positive effects of this dance intervention for the caregivers.

Alzheimer's disease (AD) is a devastating, progressive neurodegenerative disease resulting in memory loss and a severe reduction in the ability to perform activities of daily living. Ethnicity-related genetic factors promoting the development of dementias among African Americans (AA) and increased risk among women for developing AD indicates that AA women with a parental history of AD are at great risk for developing AD. This phase I study assessed the impact of a 12 week, 20-lesson adapted Argentine Tango intervention (n = 24) to a no-contact control group (n = 10) on measures of plasma inflammatory markers, cognition, and motor and psychosocial performance in middle-aged AA woman at increased risk for AD by virtue of parental history. Some woman (n = 16) were also caregivers; thus, the impact of the intervention on caregiving burden was examined in this subset. Preliminary analysis of efficacy was conducted with significance tests on biomarkers and key measures of cognition, including visuospatial and executive function, balance, and strength. After 12 weeks, Tango participants had significantly decreased inflammatory cytokine, including reductions in IL-7 (p = 0.003), IFN-γ (p = 0.011), TNFα (p = 0.011), and MCP-1 (p = 0.042) compared to controls. Large effects were noted for the Tango group on tests of executive functioning (d = 0.89), and inhibition (p = 0.031). Participants in Tango improved in dynamic and static balance (p = 0.018) and functional lower body strength (p = 0.023). Secondary assessment revealed trends favoring the intervention group were noted in spatial cognition and executive function. Moderate effects were noted in caregiving burden measures among the subset of caregivers. These data demonstrate substantial reductions in inflammatory biomarkers along with cognitive and motor improvements through a non-pharmacologic, affordable intervention among a small, well-characterized cohort of AA women with a parental history of AD.

Overview of Meta-Analyses of Five Non-pharmacological Interventions for Alzheimer's Disease

Background: Alzheimer's disease (AD) is a neurodegenerative disease characterized by progressive memory deficits, cognitive decline, and spatial disorientation. Non-pharmacological interventions to treat AD have been reported in many meta-analyses (MAs), but robust conclusions have not been made because of variations in the scope, quality, and findings of these reviews.

Objective: This work aimed to review existing MAs to provide an overview of existing evidence on the effects of five non-pharmacological interventions in AD patients on three outcomes: Mini-Mental State Examination (MMSE), activities of daily living (ADL), and Alzheimer's Disease Assessment Scale-cognitive section (ADAS-cog).

Methods: The databases PubMed, Cochrane Library, Embase, and Web of Science were searched to collect MAs of non-pharmacological interventions for AD. Two reviewers independently conducted literature screening, data extraction, and quality assessment. We assessed the quality of MAs with the Measurement Tool to Assess Systematic Reviews (AMSTAR) 2 and assessed the evidence quality for significant outcomes using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.

Results: We found 10 eligible MAs, which included between three (133 patients) and 15 randomized trials (1,217 patients), and five non-pharmacological interventions, namely, acupuncture therapy (40%), exercise intervention (30%), music therapy (10%), cognitive intervention (10%), and repetitive transcranial magnetic stimulation (rTMS) (10%). All the included MAs were critically low to low quality by AMSTAR 2. Acupuncture therapy and exercise intervention showed the preliminary potential to improve ADL and MMSE. rTMS and acupuncture therapy show benefits in decreasing ADAS-cog, and there were some evidence of improved MMSE with cognitive intervention. All these outcomes scored very low quality to moderate quality of evidence on the GRADE system.

Conclusions: Non-pharmacological therapy shows promise for the treatment of AD, but there is still a lack of high-quality evidence. In the future, the quality of the original research needs to be improved, and strictly designed MAs should be carried out following methodological requirements.
