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

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.

Effectiveness of dance interventions for falls prevention in older adults: systematic review and meta-analysis

INTRODUCTION

Fall prevention is a global health priority. Strength and balance exercise programmes are effective at reducing falls. Emerging literature suggests dance is an enjoyable and sociable form of exercise. However, there is little evidence that dance reduces fall incidence.

METHODS

Systematic review and meta-analysis examining effectiveness and cost-effectiveness of dance for falls prevention in older adults. Five databases were searched with no restrictions on publication date or intervention settings. Risk of bias was assessed using variants of Cochrane Risk of bias tools, Mixed-Methods Appraisal and Drummond checklist as appropriate. Certainty of evidence was assessed using GRADE.

RESULTS

Forty-one studies were included (19 RCTs, 13 quasi-experimental, two mixed-method, seven observational studies, 2,451 participants). Five types of dance interventions were identified: ballroom and Latin dance, dance exercise, cultural dance, dance therapy, and low-impact dance. Meta-analysis was only possible for functional outcome measures: Timed-Up-and-Go (dance versus usual care, mean difference (MD) = 1.36; 95% CI -3.57 to 0.85), Sit-to-Stand (dance versus exercise MD = -0.85; 95% CI -2.64 to 0.93: dance versus education MD = -1.64; 95% CI -4.12 to 0.85), Berg Balance Scale (dance versus usual care MD = 0.61; 95% CI -4.26 to 5.47). There was unexplained variance in effects and no significant differences between intervention and control groups. Overall, certainty of evidence was very low; we are uncertain about the effect of dance interventions in reducing falls.

CONCLUSIONS

There is very low certainty evidence for dance as an alternative to strength and balance training if the aim is to prevent falls. No robust evidence on the cost-effectiveness of dance interventions for the prevention of falls was found.

The effect of rhythmic movement on physical and cognitive functions among cognitively healthy older adults: A systematic review and meta-analysis

OBJECTIVE

To explore the effects of rhythmic movement interventions on the physical and cognitive functions among cognitively healthy older adults.

METHODS

We searched PubMed, Web of Science, Cochrane Library, EMBASE, CNKI, CBM, Wanfang Data, and VIP databases from inception to March 30, 2022. The inclusion criteria were: ① randomized controlled trials (RCTs); ② older adults (aged ≥ 60 years) without cognitive impairments or neurological or neurodegenerative diseases; ③ intervention: rhythmic movement (rhythmic exercise or physical activities performed to music); ④ outcomes: physical or cognitive function. Overall, 44 RCTs across 20 countries (n = 2752 participants) were included.

RESULTS

An association was found between rhythmic movement and improved physical function (mobility, cardiopulmonary endurance, muscle strength, flexibility, and balance), global cognitive function, and quality of life (QOL). The physical function outcomes suggested additional significant benefits when using control groups with no exercise than when using control groups with exercise. No significant improvement was found in executive function.

CONCLUSION

Regular rhythmic movement likely improves physical function, global cognitive function, and QOL in healthy older adults. The effect of rhythmic movement on the physical function in older adults is similar to that of routine exercise. Further studies on cognitive function of healthy older adults using larger samples of populations with more balanced sex ratios with long-term follow-up are particularly encouraged.

A Meta-Analysis of the Effects of Dance Programs on Physical Performance: Appropriate Health Promotion for Healthy Older Adults

Background

Dancing is a type of physical activity that has been associated with physical benefits in older adults. Regular dancing can help maintain physical function and improve the quality of life in this population. This review evaluated randomized control trials (RCTs) of the effectiveness of dance programs on the physical function of healthy older adults.

Methods

We systematically searched four databases (PubMed, Google Scholar, Embase, and ThaiLis) through December 2021 for primary studies evaluating dance programs in healthy older adults aged 60 years and over. The meta-analysis used a random-effects model to compute the effect sizes using a forest plot and Cochran’s Q and I² statistics as heterogeneity measures.

Results

Eight types of dance programs showed significantly improved physical function. Muscle strength was assessed using the five times sit-to-stand test (I²=89%; p=0.003), chair-sit-to-stand-30S test (I²=75%; p=0.006), and 30-s arm curl test (I²=22%; p=0.260). Static balance was evaluated using the Berg-balance scales test (I²=0%; p=0.620) and the one-leg-stand test (I²=32%; p=0.220). Dynamic balance was tested based on the time up-and-go and eight-foot up-and-go tests (I²=51%; p=0.110). Flexibility was assessed based on the back-scratch (I²=56%; p=0.130) and sit-and-reach test (I²=0%; p=0.930).

Conclusion

Dance exercise programs improved muscle strength, balance, and flexibility. Such programs are effective and safe for healthy older adults for use as daily exercise to promote health. Therefore, researchers, healthcare providers, and policymakers should establish properly organized dance interventions to improve physical function in healthy older adults.

Influence of Dance Programmes on Gait Parameters and Physical Parameters of the Lower Body in Older People: A Systematic Review

(1) Background: The regular practice of dancing benefits the physical condition, improving quality of life and minimising the adverse effects of ageing. Therefore, this review aims to evaluate the impact of dance programmes by quantifying different physical parameters of the lower body in older adults. (2) Methods: A systematic qualitative review in the English language (PubMed, Scopus, OvidSP, Cochrane and PEDro database) until mid-2020 considering the PRISMA guidelines and the PEDro quality criteria considering the following parameters of gait: stride length and width, speed. Physical parameters: flexion and dorsiflexion joint, muscle strength and range of motion were carried out. (3) Results: 9 studies with a population of 544 subjects from 5 continents and 6 types of dances were taken into account. The improvement of some parameters over others depended on the type of dance and the movements generated, having moderate positive effects on strength, agility, mobility and balance. (4) Conclusions: there is a general improvement in the functional capacity of the elderly through the practice of ballroom dancing, with specific improvement of each parameter depending on the type of dance.
