A comparison of dance interventions in people with Parkinson disease and older adults

Moving Towards a Medicine of Dance: A Scoping Review of Characteristics of Dance Interventions Targeting Older Adults and a Theoretical Framework

Background

Dance combines cultural and aesthetic elements with behaviors important for brain health, including physical activity, social engagement, and cognitive challenge. Therefore, dance could positively impact public health given the rapidly aging population, increasing incidence of Alzheimer's disease and related dementias, and lack of uptake of exercise in many older adults. Despite a high volume of literature, existing literature does not support evidence-based guidelines for dance to support healthy aging.

Objective

To conduct a scoping review of the dance intervention literature in older adults and provide information to facilitate a more consistent approach among scientists in designing dance interventions for older adults that stimulate physical and neurocognitive health adaptations.

Methods

Study characteristics (sample size, population, study design, outcomes, intervention details) were ascertained from 112 separate studies of dance reported in 127 papers that reported outcomes important for brain health (cardiorespiratory fitness, balance and mobility, cognition, mood, and quality of life).

Results

High heterogeneity across studies was evident. Class frequency ranged from < 1 to 5 classes per week, class length from 30-120 minutes, and intervention duration from 2 weeks to 18 months. Studies often did not randomize participants, had small (< 30) sample sizes, and used varied comparator conditions. Over 50 tests of cognition, 40 dance forms, and 30 tests of mobility were identified.

Conclusions

Based on these results, important future directions are establishing common data elements, developing intervention mapping and mechanistic modeling, and testing dosing parameters to strengthen and focus trial design of future studies and generate evidence-based guidelines for dance.

Physical exercise and its effects on people with Parkinson's disease: Umbrella review

INTRODUCTION

Parkinson's disease is neurodegenerative, complex and progressive, manifesting in a slow and irreversible way. Physical exercise has been proposed as therapeutic alternative to people with Parkinson´s disease.

OBJECTIVE

To synthesize knowledge about the effects of physical exercise on people with Parkinson´s Disease as presented by published systematic reviews.

METHODS

Nine electronic databases and two grey literature databases were searched for systematic reviews reporting the effects of physical exercises on people with Parkinson´s Disease. Searches involved a two-phase process, by, at least, two independent reviewers. Methodological quality of the included systematic reviews was assessed using AMSTAR-2.

RESULTS

From 2,122 systematic reviews, 139 were included. Motor outcomes were assessed in 91% of the studies, with balance being the most studied. Non-motor outcomes were assessed in 68% of the studies, with emphasis on quality of life. Physical exercises were classified into five categories: aerobic exercises, strength, combined, sensorimotor activities and other activity protocols. Findings of the systematic reviews suggest that all exercise categories can be prescribed to improve balance and mobility, while combined exercises, strength, and specific activities improve both motor and non-motor outcomes, and aerobic exercise and sensorimotor activities improve motor outcomes.

CONCLUSION

Current evidence from systematic reviews suggests that physical exercises impacts both motor and non-motor outcomes in people with Parkinson´s Disease. Limits in evidence provided by the systematic reviews were related to methodological issues and to the description of the interventions and must be considered to improve decision-making and clinical application.

Unleashing the potential of dance: a neuroplasticity-based approach bridging from older adults to Parkinson's disease patients

Parkinson's disease (PD) is a neurodegenerative disorder that affects >1% of individuals worldwide and is manifested by motor symptoms such as tremor, rigidity, and bradykinesia, as well as non-motor symptoms such as cognitive impairment and depression. Non-pharmacological interventions such as dance therapy are becoming increasingly popular as complementary therapies for PD, in addition to pharmacological treatments that are currently widely available. Dance as a sensorimotor activity stimulates multiple layers of the neural system, including those involved in motor planning and execution, sensory integration, and cognitive processing. Dance interventions in healthy older people have been associated with increased activation of the prefrontal cortex, as well as enhanced functional connectivity between the basal ganglia, cerebellum, and prefrontal cortex. Overall, the evidence suggests that dance interventions can induce neuroplastic changes in healthy older participants, leading to improvements in both motor and cognitive functions. Dance interventions involving patients with PD show better quality of life and improved mobility, whereas the literature on dance-induced neuroplasticity in PD is sparse. Nevertheless, this review argues that similar neuroplastic mechanisms may be at work in patients with PD, provides insight into the potential mechanisms underlying dance efficacy, and highlights the potential of dance therapy as a non-pharmacological intervention in PD. Further research is warranted to determine the optimal dance style, intensity, and duration for maximum therapeutic benefit and to determine the long-term effects of dance intervention on PD progression.

Pilot testing of a simplified dance intervention for cardiorespiratory fitness and blood lipids in obese older women

INTRODUCTION

Dance interventions require long learning periods and exert high joint loading. Therefore, a simple dance intervention is required.

AIMS

To examine the effects of simplified dance on body composition, cardiorespiratory fitness, and blood lipid levels in obese older women.

METHOD

Twenty-six obese older women were randomly assigned to exercise and control groups. The dance exercise involved pelvic tilt and rotation with basic breathing techniques. Anthropometry, cardiorespiratory fitness, and blood lipid levels were measured at baseline and after the 12-week training.

RESULTS

The exercise group had lower total cholesterol and low-density lipoprotein cholesterol levels and improved VO₂max after the 12-week training than at baseline; however, no significant difference was observed for the control group. Additionally, the exercise group had lower triglycerides and higher high-density lipoprotein cholesterol than the control group.

CONCLUSIONS

Simplified dance interventions have the potential to improve blood composition and aerobic fitness in obese older women.

The role of exercise in Parkinson's Disease

Parkinson's disease (PD) is a progressive widespread neurodegenerative disorder affecting the brain. It is characterized by dopaminergic neuron degeneration in the substantia nigra pars compacta (SNpc). Current therapeutic options ease the symptoms of PD; however, they have multiple undesirable effects and do not slow the disease progression. Exercise by itself has many positive impacts on general health. In this review, the positive impact of different forms of exercise were found to improve motor and non-motor symptoms in PD. Exercise effects is mediate by multiple mechanisms, including the upregulation of brain-derived neurotrophic factor, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor, and autophagy regulating proteins; and downregulates proinflammatory cytokines. In this review, the significance of exercise in PD, as well as in the prevention and maintenance of the disease was discussed. Many questions are left unanswered in this manuscript, including potential genetic factors underlying response to exercise. Therefore, further high-quality studies on humans are needed.

Assessment Tools of Biopsychosocial Frailty Dimensions in Community-Dwelling Older Adults: A Narrative Review

Frailty is a complex interplay between several factors, including physiological changes in ageing, multimorbidities, malnutrition, living environment, genetics, and lifestyle. Early screening for frailty risk factors in community-dwelling older people allows for preventive interventions on the clinical and social determinants of frailty, which allows adverse events to be avoided. By conducting a narrative review of the literature employing the International Narrative Systematic Assessment tool, the authors aimed to develop an updated framework for the main measurement tools to assess frailty risks in older adults, paying attention to use in the community and primary care settings. This search focused on the biopsychosocial domains of frailty that are covered in the SUNFRAIL tool. The study selected 178 reviews (polypharmacy: 20; nutrition: 13; physical activity: 74; medical visits: 0; falls: 39; cognitive decline: 12; loneliness: 15; social support: 5; economic constraints: 0) published between January 2010 and December 2021. Within the selected reviews, 123 assessment tools were identified (polypharmacy: 15; nutrition: 15; physical activity: 25; medical visits: 0; falls: 26; cognitive decline: 18; loneliness: 9; social support: 15; economic constraints: 0). The narrative review allowed us to evaluate assessment tools of frailty domains to be adopted for multidimensional health promotion and prevention interventions in community and primary care.

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.

The effect of dance on physical health and cognition in community dwelling older adults: a systematic review and meta-analysis

BACKGROUND

Dancing is an attractive form of exercise among older adults and may positively influence physical and psychosocial health. The aim of this systematic review was to synthesize the evidence examining the dance prescription and effectiveness of dance in community dwelling older adults.

METHODS

Eight databases were searched to identify randomized controlled trials that evaluated the effectiveness of dance programs on community-dwelling older adults from 2007 to December 2020. Data regarding participants, dance programs and outcomes of interest were extracted and narratively synthesized. A meta-analysis was performed on the outcome data where possible.

RESULTS

Twenty-two studies met the inclusion criteria, of those 15 were deemed to be fair quality and 7 high quality using the PEDro scale. Nineteen studies included in the meta-analysis found that dancing can improve mobility and endurance compared to no intervention and afforded equivalent outcomes compared to other exercise programs.

CONCLUSION

The findings suggest that dance is an effective, safe and viable activity for community-dwelling older adults..

The Effects of a Dance and Music-Based Intervention on Parkinson's Patients' Well-Being: An Interview Study

Previous research has shown the positive effects of music and dance-based interventions on the physical and psychosocial symptoms of Parkinson’s disease (PD). The aims of this study were: (1) to investigate how PD patients subjectively perceive the emotional, cognitive, and social benefits of a music- and dance-based intervention; (2) to apply an innovative methodology for an interview analysis combining findings from a linguistic text with an analytic approach and conducted with the software LIWC and from the content analysis performed by human coders. Extensive, open-ended interviews were conducted with 13 patients with PD who had participated in a dance and music program. The interviews were analyzed using both human coders and the computer-based approach. The results show that emotional and social aspects are considered the most frequent perceived benefits of the dance program. The data confirm the positive impact of dance- and music-based programs on promoting participants’ emotional and social well-being. A combined approach to text analysis appears to be a promising way to achieve more in-depth insights into patients’ subjective perceptions.

Characterization of dance-based protocols used in rehabilitation - A systematic review

Objective

To describe the use of dance-based intervention protocols as a rehabilitation proposal.

Method

Papers containing protocols used in adult patients and written in Spanish, English, and Portuguese were collected using the following keywords: Physical Therapy; Dance Therapy; Rehabilitation; and Clinical Trial Protocol. The PUBMED, MEDLINE, LILACS, BVS ScienceDirect, PEDro, OTseeker, The Cochrane Library (Cochrane Central Register of Controlled Trials), and Scopus databases were used for the collection of information to define the type of dance, the established protocol, pathologies, and the population involved.

Results

70 studies met the eligibility criteria, all of which presented a dance protocol. This was used in the rehabilitation of pathologies covering the neuromuscular, musculoskeletal, and cardiovascular systems, as well as in a healthy population. Positive results were the main outcome measure.

Discussion

Dance is an innovative intervention strategy for patients with comorbidities or underlying pathologies as well as for those in good health. It offers, without limitations, a field of applicability through the use of a dancing style as a rehabilitation process, generating significant changes in the physical, mental, and social skills of the individual.

Dance Is an Accessible Physical Activity for People with Parkinson's Disease

OBJECTIVE

To evaluate the outcomes of face-to-face, digital, and virtual modes of dancing for people living with Parkinson's disease (PD).

DESIGN

Systematic review informed by Cochrane and PRIMSA guidelines. Data Sources. Seven electronic databases were searched: AMED, Cochrane, PEDro, CINHAL, PsycINFO, EMBASE, and MEDLINE.

METHODS

Eligible studies were randomised controlled trials (RCT) and other trials with quantitative data. The PEDro scale evaluated risk of bias for RCTs. Joanna Briggs Institute instruments were used to critically appraise non-RCTs. The primary outcome was the feasibility of dance interventions, and the secondary outcomes included gait, balance, quality of life, and disability.

RESULTS

The search yielded 8,327 articles after duplicates were removed and 38 met the inclusion criteria. Seven were at high risk of bias, 20 had moderate risk of bias, and 11 had low risk of bias. There was moderately strong evidence that dance therapy was beneficial for balance, gait, quality of life, and disability. There was good adherence to digital delivery of dance interventions and, for people with PD, online dance was easy to access.

CONCLUSION

Dancing is an accessible form of exercise that can benefit mobility and quality of life in people with PD. The COVID-19 pandemic and this review have drawn attention to the benefits of access to digital modes of physical activity for people living with chronic neurological conditions.

Parkinson's Disease Motor Symptom Progression Slowed with Multisensory Dance Learning over 3-Years: A Preliminary Longitudinal Investigation

Parkinson's disease (PD) is a neurodegenerative disease that has a fast progression of motor dysfunction within the first 5 years of diagnosis, showing an annual motor rate of decline of the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) between 5.2 and 8.9 points. We aimed to determine both motor and non-motor PD symptom progression while participating in dance classes once per week over a period of three years. Longitudinal data was assessed for a total of 32 people with PD using MDS-UPDRS scores. Daily motor rate of decline was zero (slope = 0.000146) in PD-Dancers, indicating no motor impairment, whereas the PD-Reference group showed the expected motor decline across three years (p < 0.01). Similarly, non-motor aspects of daily living, motor experiences of daily living, and motor complications showed no significant decline. A significant group (PD-Dancers and PD-Reference) by days interaction showed that PD who train once per week have less motor impairment (M = 18.75) than PD-References who do not train (M = 24.61) over time (p < 0.05). Training is effective at slowing both motor and non-motor PD symptoms over three years as shown in decreased scores of the MDS-UPDRS.

Effects of a Modified Tap Dance Program on Ankle Function and Postural Control in Older Adults: A Randomized Controlled Trial

Older adults are at a high risk of falling due to age-related degradations in physical fitness. This study aimed to examine the effects of a modified tap dance program (MTD) on ankle function and postural control in older adults. Forty-four healthy older adults (mean age = 64.1 years, with 9 men) were recruited from local communities and were randomly divided into the MTD group and the control (CON) group. The MTD group received 12 weeks of MTD training 3 times per week for 30 min per session. Outcomes were measured using the five times sit-to-stand test (FTSST) for ankle strength, the universal goniometer for ankle range of motion, and the Footscan^® to trace the center of pressure. Results revealed significant improvements in FTSST in the MTD group (mean difference = 1.01), plantar flexion (left = 9.10, right = 10.0). In addition, the MTD group displayed significantly more improvements at midtest than the CON group in FTSST (mean difference = 1.51) and plantar flexion (mean difference: left = 6.10; right = 4.5). Therefore, the MTD can be an effective exercise program for ankle function improvement, but it has limited effects on improving postural control among healthy older adults.

Dance Intervention Affects Social Connections and Body Appreciation Among Older Adults in the Long Term Despite COVID-19 Social Isolation: A Mixed Methods Pilot Study

The ability of dance to address social isolation is argued, but there is a lack of both evidence of such an effect and interventions designed for the purpose. An interdisciplinary research team at University of Calgary partnered with Kaeja d’Dance to pilot test the effects of an intervention designed to facilitate embodied social connections among older adults. Within a mixed methods study design, pre and post behavioral tests and qualitative surveys about experiences of the body and connecting were administered to thirteen participants along with test instruments of loneliness and body appreciation. In the short-term, no significant changes were found on quantitative tests. Exploratory analysis revealed intervention improvements on individual body appreciation questions only. This indication of change was strongly supported by converging qualitative data and identified as relating to: increased connection through task-based collaboration, increased awareness of interpersonal boundaries, and a shift to experiencing the body as responsive. These indications of increased relational capacity were deemed likely to cause further impact in the long term. Examining this possibility and the subsequently arisen factor of COVID-19 risks and restrictions, test instruments were administered again to 10 participants 4 and 5 months after the intervention. A significant increase in loneliness was found. Despite this negative impact of COVID-19 isolation, several positive intervention changes remained detectable and some continued to increase over time. Seventy percent of the participants, who made new social contacts during the intervention and later sought continued contact, improved significantly across all body appreciation measures over the full study. The qualitative data from the last two time-points revealed both consistent values and new, negative changes. While these preliminary findings speak to the durability of intervention changes, they also identify areas of urgent priority to help older adults restore embodied relational capacity that has declined during COVID-19. Within the limitations of a small-sample pilot study, converging mixed methods results support the hypothesis that dance interventions designed for the purpose can positively affect the social inclusion of older adults. Although we recommend further study, these promising results also indicate that dance interventions can help older adults recover from pandemic isolation.

How COVID-19 will boost remote exercise-based treatment in Parkinson's disease: a narrative review

The lack of physical exercise during the COVID-19 pandemic-related quarantine measures is challenging, especially for patients with Parkinson's disease (PD). Without regular exercise not only patients, but also nursing staff and physicians soon noticed a deterioration of motor and non-motor symptoms. Reduced functional mobility, increased falls, increased frailty, and decreased quality of life were identified as consequences of increased sedentary behavior. This work overviews the current literature on problems of supplying conventional physiotherapy and the potential of telerehabilitation, allied health services, and patient-initiated exercise for PD patients during the COVID-19 period. We discuss recent studies on approaches that can improve remote provision of exercise to patients, including telerehabilitation, motivational tools, apps, exergaming, and virtual reality (VR) exercise. Additionally, we provide a case report about a 69-year-old PD patient who took part in a 12-week guided climbing course for PD patients prior to the pandemic and found a solution to continue her climbing training independently with an outdoor rope ladder. This case can serve as a best practice example for non-instructed, creative, and patient-initiated exercise in the domestic environment in difficult times, as are the current. Overall, many recent studies on telemedicine, telerehabilitation, and patient-initiated exercises have been published, giving rise to optimism that facilitating remote exercise can help PD patients maintain physical mobility and emotional well-being, even in phases such as the COVID-19 pandemic. The pandemic itself may even boost the need to establish comprehensive and easy-to-do telerehabilitation programs.

Binary dance rhythm or Quaternary dance rhythm which has the greatest effect on non-motor symptoms of individuals with Parkinson's disease?

This study aimed to compare the effect of a binary and quaternary rhythm protocol on cognition, mental activity, daily life, and quality of life among individuals with Parkinson's Disease. A two-arm randomized clinical trial with 31 individuals diagnosed with Parkinson's disease, who were allocated to the binary group or quaternary group. Both groups underwent a 12-week intervention. The following variables were analyzed: personal and clinical information; MoCA; UPDRSI and II; PDQ-39. Both intervention groups improved cognition, mental activity, activities of daily living, and quality of life. In addition, there were intergroup differences in total UPDRSII, writing, and hygiene where the quaternary group was superior to the binary group. It concludes that the binary and quaternary rhythm positively influenced and presented similar effects on the complementary treatment of individuals with Parkinson's disease on the studied variables. Thus, it is believed that both interventions are possible and feasible for the health professionals involved in the area.

Dance intervention effects on physical function in healthy older adults: a systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

Dancing is a form of physical exercise associated with health benefits in older adults. Regular dancing can prolong healthy aging, maintain or even improve physical function, and thus enhance their quality of life. The aim of this review was to evaluate the effects of dance intervention on physical function performance in healthy older adults in randomized-controlled trials (RCTs).

METHODS

Five electronic databases (Cochrane Library, PsycINFO, PubMed, Scopus, and Web of Science) were searched systematically until the end of June 2018 by two independent reviewers. These searches were limited to the English language and persons with average age older than 65. The tool from the Cochrane Collaboration was used to assess the risk of bias. A standard meta-analysis was performed using Review Manager Software version 5.3.

RESULTS

Thirteen RCTs from a total of 1029 older participants were included in this meta-analysis. The results showed that dance intervention significantly improved mobility function and endurance performance when compared with control groups for healthy older adults. However, gait was not significantly improved through dancing. Studies included in this review were not enough to perform meta-analysis for the effectiveness of dance on balance and general health in healthy older adults.

CONCLUSION

Overall, dance intervention was effective to improve physical function performance in healthy older adults. The results from this meta-analysis strengthen the evidence from previous individual studies. Properly organized dance intervention would be a safe and effective exercise to incorporate into daily life.

Promoting wellbeing and health through active participation in music and dance: a systematic review

Purpose: This review aims to reveal how music and dance participation relates to key social determinants of health, and acts as population wellbeing and health promotion and preventive tools for people without pre-existing health issues in diverse social groups.

Methods: A qualitative systematic literature review addresses the questions: 1) How might music and dance cultural practices relate to social determinants of health?; 2) What gaps exist in the current body of research examining how healthy individuals/populations maintain and promote good health and wellbeing through music and dance participation?; 3) What are the implications of the current body of literature for healthcare, policy and research?

Results: Music and dance relate to key social determinants of health, from social and cultural, and physical and mental health perspectives. A number of gaps in the literature exist, including underrepresentation of middle aged participants, men, and Indigenous, LGBTQIAP+, and migrant populations. There is a lack of consistency in theoretical and methodological approaches, and a language for effective communication across arts and health audiences.

Conclusions: A significant opportunity exists for cross-disciplinary collaboration to advance healthcare and arts policy, generate cost-effective approaches to preventive healthcare practice, and enhance the wellbeing and health of large and diverse populations.

PasoDoble, a Proposed Dance/Music for People With Parkinson's Disease and Their Caregivers

Managing the heterogeneity of Parkinson's disease symptoms and its progressive nature demands strategies targeting the hallmark disrupted neurotransmission but also the comorbid derangements and bolstering neuroprotection and regeneration. Strong efforts are done to find disease-modifying strategies, since slowing disease progression is not enough to hamper its burden and some motor symptoms are resistant to dopamine-replacement therapy. The inclusion of non-pharmacological strategies can provide such a multitarget umbrella approach. The silent long-term biological process that precedes the clinical onset of disease is a challenge but also an opportunity to reinforce healthy lifestyle known to exert preventive/therapeutic effects. These non-pharmacological strategies are foreseen as able to reduce the prevalence and the global impact of long-term diseases demanding strong management of patient-caregiver quality of life. In this regard, European guidelines for Parkinson's disease recommend physical-related activities such as aerobic exercise and dancing known to improve functional mobility and balance in patients. Here, we propose “PasoDoble,” a novel dance/music patient-caregiver intervention with additional preventive value. The rationale is founded on evidence-based therapeutic benefits of dance/music therapy and the singular features of this widely extended Hispanic dance/music targeting motor symptoms, mood/cognition, and socialization: (i) As a dance, an easy and simple double-step pattern (back-and-forward and lateral movements) that evolves from a spontaneous individual dance to a partnered dancing, performed in social groups and involving dancing-figures of increasing complexity; (ii) “PasoDoble,” as a music that can be sung, has musical rhythmicity with high groove and familiarity that will help to synchronize the steps to the rhythm of music; (iii) Widely extended (Spain, Mexico, Puerto Rico, Colombia, and USA) and easy-to-learn for others. As a regular dancing “PasoDoble” can improve and preserve function, mood and socialization, as an intervention the method is structured to improve gait and balance; facilitate movement, reaching and grasping; muscle power and joint mobility; reduce of risk of falls, and increase of aerobic capacity. Finally, this easy-to-implement into patient care and free-living environments (elderly social centers, home care) rehabilitation programs can promote positive emotions and self-esteem, with added general improvement of social attachment and recognition, thus improving the quality of life of patient-caregiver.

Chasing Protection in Parkinson's Disease: Does Exercise Reduce Risk and Progression?

Exercise may be the most commonly offered yet least consistently followed therapeutic advice for people with Parkinson's disease (PD). Epidemiological studies of prospectively followed cohorts have shown a lower risk for later developing PD in healthy people who report moderate to high levels of physical activity, and slower rates of motor and non-motor symptom progression in people with PD who report higher baseline physical activity. In animal models of PD, exercise can reduce inflammation, decrease α-synuclein expression, reduce mitochondrial dysfunction, and increase neurotrophic growth factor expression. Randomized controlled trials of exercise in PD have provided clear evidence for short-term benefits on many PD measurements scales, ranging from disease severity to quality of life. In this review, we present these convergent epidemiological and laboratory data with particular attention to translationally relevant features of exercise (e.g., intensity requirements, gender differences, and associated biomarkers). In the context of these findings we will discuss clinical trial experience, design challenges, and emerging opportunities for determining whether exercise can prevent PD or slow its long-term progression.

Effects of Dance on Gait, Cognition, and Dual-Tasking in Parkinson's Disease: A Systematic Review and Meta-Analysis

Dance-based interventions have been proposed for the management of Parkinson's disease (PD) symptoms. This review critically appraises and synthesises the research on the effects of dance interventions on gait, cognition and dual-tasking in PD, through a meta-analysis of peer-reviewed literature from seven databases. Eligible studies included people with PD, used a parallel-group or cohort design with a dance-based intervention, reported outcome measures of gait, cognition or dual-tasking, and were published in English up until September 2017. Of the initial 1079 articles, 677 articles were reviewed for eligibility, and 25 articles were retained. Only 12 articles had sufficient common assessment items for meta-analysis. Two independent reviewers extracted the data and assessed the risk of bias of each study using the Cochrane risk-of-bias tool. Based on pre-post change scores, gait speed, Timed Up and Go (TUG) test performance, freezing of gait questionnaire, and six-minute walk test times significantly improved after a dance intervention compared to controls. Global cognition assessed with Montreal Cognitive Assessment, and cognitive dual-tasking measured using dual-task TUG, also exhibited greater improvement in dance groups. There was limited evidence to determine the most effective intensity, frequency, duration of dance interventions or the most beneficial music. Findings must be interpreted cautiously because of the lack of randomised control trials, and the moderate to high risk of bias of studies. However, the results of papers with level-I and level-II.1 evidence suggest that dance may have the potential to ameliorate PD symptoms, particularly gait, global cognition and cognitive dual-tasking.

Perceived effects of Tango Argentino on body experience in persons with Parkinson's disease (PD)-A qualitative study with affected persons and their partners

BACKGROUND

Persons with Parkinson's disease (PD) experience somatic and psycho-emotional limitations. As a neurodegenerative disease with increasing motor symptoms, PD changes the body experience. Embodied activities like dancing are beneficial to individuals with PD regarding mobility, balance and body feeling. The objective of this study was to assess the impact of Tango Argentino (TA) on body experience in individuals with PD.

METHODS

This qualitative study was conducted among 12 individuals with PD and their dance partners participating in TA courses for persons with PD and uses semi-standardized interviews. The heterogeneity of the sample was mainly based on the number of TA classes, so that participants were distinguished in participants with 10 h (beginners) and participants with more than 10 h (advanced). Further variance was due to different age groups and duration of disease.

RESULTS

Participants reported change on five categories of body experiences: body awareness, motor symptoms and movement, general feelings, body sensations and disease-related feelings. Participants cited a shift in body awareness and improved stability, walking safety, enhanced mobility and amelioration in gestures and facial expressions. In general, participants described reduced body fatigue, anxiety, shame and frustration and increase in joy, pride, curiosity as well as reinforcement of partnership. With regard to perception, positive and negative feelings, ease, relaxation and increase of inner congruence were reported. The experience of normality and health helped to generate greater acceptance of disease burdens and to develop self-confidence and self-assurance. Dance partners confirmed the perceptions of the dancers with PD.

CONCLUSION

The perceived effects of TA courses may be linked to a positive body awareness and body control which may be related improved motor symptoms, social and everyday life. These perceived effects should be controlled in relation to the long time change in embodied activity and body experience in persons with PD.

Effects of dance activities on patients with chronic pathologies: scoping review

Introduction

Physical inactivity often accompanies chronic pathologies. This induces a sedentariness that favors complications and patient isolation. There is a growing scientific interest in the practice of art, for such activities leave the usual healthcare framework and include the World Health Organization (WHO)'s three dimensions of health. Dance is a universal activity that has been identified as healthy. This scoping review's aim is to study the benefits, modalities and risks of dance for persons with a chronic pathology.

Method

The literature research was conducted in English and French, using PubMed and Kinedoc's databases, and keywords related to dance and chronic pathologies. Dance activities that did not involve a dance instructor or a trained health professional were excluded. Studies' location and design, the chosen type of dance, pathologies, the number of subjects, modalities, intended effects and adverse effects were then studied.

Results

51 studies were included in this work. 47.5% were RCTs and 47% originate from North America. The number of published studies is strongly increasing. Sixteen different pathologies were studied, with a large predominance of neurology diseases. Targeted effects were the impacts on mental health, quality of life, physical and motor capacities and pathology-specific symptoms. Dance activities are deemed feasible, and no adverse effects were identified.

Discussion

In the event of chronic pathologies, practicing dance is possible; it is stimulating and effective against sedentariness and its adverse effects. Patient adherence is good, and dance seems to respond to the multidimensional component of chronic diseases, while offering unlimited adaptation to patients' physical and cognitive impairments. There are few studies yet, and their methodological quality is moderate, which is why further research work must confirm dance's interest regarding chronic pathologies.

Exercise for Parkinson's disease

Parkinson's disease is the second most common neurodegenerative disease with a prevalence rate of 1-2 per 1000 of the population worldwide. Pharmacological management is the mainstay of treatment. Despite optimal medication, motor impairment particularly balance and gait impairment persist leading to various degree of disability and reduced quality-of-life. The present review describes motor impairment including postural impairment, gait dysfunction, reduced muscle strength and aerobic capacity and falls. Physical therapy and complementary exercises have been proven to improve motor performance and functional mobility. Evidence on the efficacy of physical therapy and complementary exercises is presented in this review. These exercises include gait training with cues, gait training with treadmill, Nordic walking, brisk walking, balance training, virtual reality interventions, Tai Chi and dance. All these treatment interventions produce short-term beneficial effects and some interventions demonstrate long-term benefit. Gait training with treadmill enhance walking performance and the effects sustain for 3-6 months. Balance training improves balance, function and reduces fall rate, and these effects carry over to at least 12 months after training ended. Sustained Tai Chi for 6 months, dance therapy for 12 months, progressive resistive training for 24 months alleviates the PD motor symptoms, suggesting that they could slow down PD progression. Based on this evidence, individuals with PD are encouraged to sustain their training in order to improve/maintain their physical ability and to combat the progression of PD.

"If you can breathe, you can dance": Fine lines contemporary dance for mature bodies in Melbourne, Australia

Older women ballet and contemporary dancers resist the pervasive stereotypes of the dancing body as young, graceful, and athletic. They embody and enact a generative habitus, resisting cultural socialization that would deny them voice, visibility, and validation. This study explores the understandings of a group of older women dancers who are members of the Fine Lines contemporary dance ensemble for mature bodies, Melbourne, Australia. The data for this phenomenological study were gathered in 2017 and employ Interpretative Phenomenological Analysis as an analytic strategy. Our findings are reported under three overarching themes: Dance as a Community, Older Women Dancing, and Learning: Choreography and Improvisation.

Music Therapy and Dance as Gait Rehabilitation in Patients With Parkinson Disease: A Review of Evidence

AIM

This review aims to demonstrate the efficiency of music and dance for gait improvement and symptom alleviation in Parkinson disease.

METHODOLOGY

Studies that analyzed sound stimuli and dance in gait improvement in Parkinson disease were searched through PubMed, Scopus, Doaj, MEDLINE, and ScienceDirect databases from November 2017 to April 2018 and repeated in September 2018.

RESULTS AND DISCUSSION

Forty-five studies met the inclusion criteria to synthesize the findings on dance and music performance as a treatment for classical symptoms of Parkinson disease. Five reviews and 40 experimental papers have shown that rhythmic stimulation and dance provide the motor, cognitive, and quality of life benefits for participants with Parkinson disease. Thus, sound stimuli and dance offer satisfactory effects for gait, improving cognitive abilities such as motor control and adjustment and spatial memory. In addition, these new treatment modalities stimulate the elderly population to practice physical exercise, generating well-being and helping self-esteem.

CONCLUSION

Dance and music therapy interventions are noninvasive, simple treatment options, which promote gait and cognition.

Alternative Treatment Modalities and Its Effect in Older Populations

Aging is an inevitable multifactorial process. Advances in health care and technology have led to an increase on expected life span that can reach an average of 90 years in the next few decades. Lifestyle changes that include activity, nutrition, stress management, and alternatives low-impact exercises like yoga and tai chi can help us modify some of these age-related changes and lead to an increase in the health span and quality of life of the older adults.

Link Between Parkinson Disease and Rapid Eye Movement Sleep Behavior Disorder With Dream Enactment: Possible Implications for Early Rehabilitation

The purpose of this article is 2-fold: first, to inform readers of the link between the loss of motor inhibition during rapid eye movement (REM) sleep dreaming, diagnosed as REM sleep behavior disorder, and the future onset of neurodegenerative disorders, such as Parkinson disease and dementia with Lewy bodies; it has been reported that motor disinhibition during REM sleep often precedes the onset of these disorders by years or even decades; second, to consider that the identification of REM sleep behavior disorder and the early involvement of rehabilitation and/or development of home exercise plans may aid in prolonging and even increasing function, independence, and quality of life, should such neurodegenerative disorders develop later in life.

Dancing for Parkinson Disease: A Randomized Trial of Irish Set Dancing Compared With Usual Care

OBJECTIVE

To examine the feasibility of a randomized controlled study design and to explore the benefits of a set dancing intervention compared with usual care.

DESIGN

Randomized controlled design, with participants randomized to Irish set dance classes or a usual care group.

SETTING

Community based.

PARTICIPANTS

Individuals with idiopathic Parkinson disease (PD) (N=90).

INTERVENTIONS

The dance group attended a 1.5-hour dancing class each week for 10 weeks and undertook a home dance program for 20 minutes, 3 times per week. The usual care group continued with their usual care and daily activities.

MAIN OUTCOME MEASURES

The primary outcome was feasibility, determined by recruitment rates, success of randomization and allocation procedures, attrition, adherence, safety, willingness of participants to be randomized, resource availability, and cost. Secondary outcomes were motor function (motor section of the Unified Parkinson's Disease Rating Scale), quality of life (Parkinson's Disease Questionnaire-39), functional endurance (6-min walk test), and balance (mini-BESTest).

RESULTS

Ninety participants were randomized (45 per group). There were no adverse effects or resource constraints. Although adherence to the dancing program was 93.5%, there was >40% attrition in each group. Postintervention, the dance group had greater nonsignificant gains in quality of life than the usual care group. There was a meaningful deterioration in endurance in the usual care group. There were no meaningful changes in other outcomes. The exit questionnaire showed participants enjoyed the classes and would like to continue participation.

CONCLUSIONS

For people with mild to moderately severe PD, set dancing is feasible and enjoyable and may improve quality of life.

White Matter Integrity Declined Over 6-Months, but Dance Intervention Improved Integrity of the Fornix of Older Adults

Degeneration of cerebral white matter (WM), or structural disconnection, is one of the major neural mechanisms driving age-related decline in cognitive functions, such as processing speed. Past cross-sectional studies have demonstrated beneficial effects of greater cardiorespiratory fitness, physical activity, cognitive training, social engagement, and nutrition on cognitive functioning and brain health in aging. Here, we collected diffusion magnetic resonance (MRI) imaging data from 174 older (age 60–79) adults to study the effects of 6-months lifestyle interventions on WM integrity. Healthy but low-active participants were randomized into Dance, Walking, Walking + Nutrition, and Active Control (stretching and toning) intervention groups (NCT01472744 on ClinicalTrials.gov). Only in the fornix there was a time × intervention group interaction of change in WM integrity: integrity declined over 6 months in all groups but increased in the Dance group. Integrity in the fornix at baseline was associated with better processing speed, however, change in fornix integrity did not correlate with change in processing speed. Next, we observed a decline in WM integrity across the majority of brain regions in all participants, regardless of the intervention group. This suggests that the aging of the brain is detectable on the scale of 6-months, which highlights the urgency of finding effective interventions to slow down this process. Magnitude of WM decline increased with age and decline in prefrontal WM was of lesser magnitude in older adults spending less time sedentary and more engaging in moderate-to-vigorous physical activity. In addition, our findings support the anterior-to-posterior gradient of greater-to-lesser decline, but only in the in the corpus callosum. Together, our findings suggest that combining physical, cognitive, and social engagement (dance) may help maintain or improve WM health and more physically active lifestyle is associated with slower WM decline. This study emphasizes the importance of a physically active and socially engaging lifestyle among aging adults.

The Embodied Self in Parkinson's Disease: Feasibility of a Single Tango Intervention for Assessing Changes in Psychological Health Outcomes and Aesthetic Experience

Background: Dance is an embodied activity with benefits for mobility, balance, and quality of life (QoL) of persons affected by Parkinson's Disease (PD). It is enjoyable and likely to support adherence to movement prescriptions. The objective of this study was to assess the feasibility of measuring changes in psychological outcomes, specifically well-being, body self-efficacy, outcome expectations, and experienced beauty after a single Argentine Tango intervention in a workshop format. To anchor experienced beauty in a theory, the article introduces a model of embodied aesthetics featuring active art-making as a central aspect of healing in arts-based interventions.

Methods: In a single-group pre–post design, we tested the feasibility of measuring psychological changes of 34 PD patients from Southern Germany after an introductory workshop in Argentine Tango. They participated in a 90 min Tango for PD intervention and completed the Heidelberg State Inventory (HSI-24; (Koch et al., 2007)), the Body Self-Efficacy Scale (BSE; (Fuchs and Koch, 2014)) with a sub-dimension on aesthetic experience, and the Credibility-Expectancy Questionnaire (CEQ; (Devilly and Borkovec, 2000)) before and after the intervention. A subgroup completed the therapeutic factors of arts therapies-scale, a new measure to elaborate on the aesthetic experience. We analyzed pre–post-differences with a t-test for paired samples.

Results and Discussion: The study supports the feasibility of measuring health-related psychological changes from a single Argentine Tango intervention for PD patients, as well as acceptance and appropriateness of the intervention for the patient group. After the tango intervention, well-being, body self-efficacy, and outcome expectancies increased. Participants also experienced an increase in beauty of their movements and other aesthetic aspects. We suspect that, in addition to the functional and psychological factors identified so far, the aesthetic experience in dance may be an important therapeutic factor mediating several outcomes of dance and other arts-based interventions. A controlled study for evidence-based testing of targeted variables can now follow to examine the new hypotheses.

Human behavioral assessments in current research of Parkinson's disease

Parkinson's disease (PD) is traditionally classified as a movement disorder because patients mainly complain about motor symptoms. Recently, non-motor symptoms of PD have been recognized by clinicians and scientists as early signs of PD, and they are detrimental factors in the quality of life in advanced PD patients. It is crucial to comprehensively understand the essence of behavioral assessments, from the simplest measurement of certain symptoms to complex neuropsychological tasks. We have recently reviewed behavioral assessments in PD research with animal models (Asakawa et al., 2016). As a companion volume, this article will systematically review the behavioral assessments of motor and non-motor PD symptoms of human patients in current research. The major aims of this article are: (1) promoting a comparative understanding of various behavioral assessments in terms of the principle and measuring indexes; (2) addressing the major strengths and weaknesses of these behavioral assessments for a better selection of tasks/tests in order to avoid biased conclusions due to inappropriate assessments; and (3) presenting new concepts regarding the development of wearable devices and mobile internet in future assessments. In conclusion we emphasize the importance of improving the assessments for non-motor symptoms because of their complex and unique mechanisms in human PD brains.

Impacts of dance on non-motor symptoms, participation, and quality of life in Parkinson disease and healthy older adults

Evidence indicates exercise is beneficial for motor and non-motor function in older adults and people with chronic diseases including Parkinson disease (PD). Dance may be a relevant form of exercise in PD and older adults due to social factors and accessibility. People with PD experience motor and non-motor symptoms, but treatments, interventions, and assessments often focus more on motor symptoms. Similar non-motor symptoms also occur in older adults. While it is well-known that dance may improve motor outcomes, it is less clear how dance affects non-motor symptoms. This review aims to describe the effects of dance interventions on non-motor symptoms in older adults and PD, highlights limitations of the literature, and identifies opportunities for future research. Overall, intervention parameters, study designs, and outcome measures differ widely, limiting comparisons across studies. Results are mixed in both populations, but evidence supports the potential for dance to improve mood, cognition, and quality of life in PD and healthy older adults. Participation and non-motor symptoms like sleep disturbances, pain, and fatigue have not been measured in older adults. Additional well-designed studies comparing dance and exercise interventions are needed to clarify the effects of dance on non-motor function and establish recommendations for these populations.
