Cross-sectional study of prevalence and correlates of fear of falling in the older people in residential care in India: the Hyderabad Ocular Morbidity in Elderly Study (HOMES)

OBJECTIVE

To report the prevalence and risk factors for the fear of falling (FOF) among older individuals living in residential care facilities in India.

DESIGN

Cross-sectional study.

SETTING

Homes for the aged centres in Hyderabad, India.

PARTICIPANTS

The study included individuals aged ≥60 years from homes for the aged centres. The participants underwent a comprehensive eye examination in make-shift clinics setup in homes. Trained investigators collected the personal and demographic information of the participants and administered the Patient Health Questionnaire-9 and Hearing Handicap Inventory for Elderly questionnaire in the vernacular language. FOF was assessed using the Short Falls Efficacy Scale. The presence of hearing and visual impairment in the same individual was considered dual sensory impairment (DSI). A multiple logistic regression analysis was done to assess the factors associated with FOF.

PRIMARY OUTCOME MEASURE

FOF.

RESULTS

In total, 867 participants were included from 41 homes for the aged centres in the analyses. The mean (±SD) age of the participants was 74.2 (±8.3) years (range 60-96 years). The prevalence of FOF was 56.1% (95% CI 52.7% to 59.4%; n=486). The multivariate analysis showed that those with DSI had eleven times higher odds of reporting FOF than those with no impairment (OR 11.14; 95% CI 3.15 to 41.4.) Similarly, those with moderate depression had seven times higher odds (OR 6.85; 95% CI 3.70 to 12.70), and those with severe depression had eight times higher odds (OR 8.13; 95% CI 3.50 to 18.90) of reporting FOF. A history of falls in the last year was also associated with increased odds for FOF (OR 1.52; 95% CI 1.03 to 2.26).

CONCLUSION

FOF is common among older individuals in residential care in India. Depression, falling in the previous year and DSI were strongly associated with FOF. A cross-disciplinary approach may be required to address FOF among the older people in residential care in India.

Effects of a Yoga Program Combined with a Mediterranean Diet on Nutritional Status and Functional Capacity in Community-Dwelling Older Adults: A Randomized Controlled Clinical Trial

(1) Background: With the aging population, effective interventions are needed to enhance the health of older adults. This study investigated the combined effects of yoga and the Mediterranean diet on various health outcomes in community-dwelling older adults; (2) Methods: The study employed a randomized controlled trial design with a total of 116 older adults randomized to an experimental group (n = 57) that underwent a combined yoga and Mediterranean diet program and a control group (n = 59) that did not receive any intervention. Nutritional status was assessed using the Mini Nutritional Assessment, flexibility with the Back Scratch Test and the Chair Sit-and-Reach Test, balance, gait, and fall risk with the Tinetti Scale, and muscle strength with a dynamometer and the 30 s Chair Stand Test; (3) Results: Regarding nutritional status, there were significant differences between the experimental group and the control group (Cohen's d = 0.02). The participants in the experimental group showed greater balance (11.12 ± 3.01 vs. 10.03 ± 2.35, Cohen's d = 0.41 and gait (7.63 ± 1.96 vs. 6.69 ± 2.50, Cohen's d = 0.44) with respect to the control group. In terms of flexibility, the experimental group showed statistically significant improvements in the right arm (Cohen's d = 0.43), left arm (Cohen's d = 0.64), right perineum (Cohen's d = 0.42), and left leg (Cohen's d = 0.37) Finally, in terms of strength, participants in the experimental group experienced statistically significant improvements in grip strength and lower body strength (Cohen's d = 0.39 and 0.81, respectively); (4) Conclusions: The study highlights the potential benefits of a 12-week intervention combining yoga with a Mediterranean diet to improve the health and functional capacities of community-dwelling older adults.

The effects of adapted mind-body exercises on physical function, quality of life and wellbeing for older people: a systematic review and meta-analysis

BACKGROUND

Participating in physical activity programmes is one way to optimise wellbeing and quality of life in older adults. Mind-body exercises could provide greater benefits than other forms of traditional physical activity and can be easily adapted for older people who are starting to develop functional decline.

OBJECTIVES

To synthesise the literature looking at the effects of adapted mind-body interventions on older people.

DESIGN

A systematic review and meta-analysis was conducted on articles from Web of Science, MEDLINE, SPORTDiscus, AMED and CINAHL that were searched up to 13 September 2023. Studies were extracted and assessed by two authors and included if they were adapted mind-body quasi experimental trials (QET) or randomised controlled trials (RCT) evaluating physical function, quality of life or wellbeing in community dwelling older adults aged 60 years and over. The Cochrane Risk of Bias 2 scale was used for quality appraisal. Analysis of the results included calculating standardised effect sizes (Hedge's g) and a narrative synthesis of results not included in meta-analysis.

RESULTS

18 studies (8 quasi-experimental trial designs, n = 310; 10 randomised control trials, n = 1829) were included in the systematic review, with 14 studies (9 RCT, n = 1776, 5 QET, n = 100) retained for meta-analysis. For the RCT studies, some improvement was noted in mobility (ES 0.36: 95% CI: 0.01, 0.71), flexibility (ES 0.36: 0.01, 0.70), well-being (ES 0.54: 0.18, 0.91) and quality of life (ES 0.50: 0.21, 0.79). No positive effect was observed for leg power (ES 0.09: -0.33, 0.51), leg endurance (ES 0.16: -0.72, 1.03), back scratch test (ES 0.24: -0.10, 0.59), or balance, (ES 0.05: -0.06, 0.15). Heterogeneity varied from 0%-87% across the different outcomes. For the QET studies, gait velocity was shown to improve (ES 0.54: 0.18, 0.91), while fear of falling showed no significant improvements (ES 0.82: -0.06, 1.69). A meta-regression for quality of life in which the total physical activity of the intervention, in hours, was used as a covariate, showed ES = 1.1 for every 100 h of physical activity.

CONCLUSION

There is scope for adapted mind-body physical activity interventions to play a role in improving quality of life, wellbeing, and physical function in older adults. The provision of adapted interventions for older people might improve uptake of and engagement with physical activity interventions in older people with limited or reduced abilities.

Yoga therapy on elderly patients with fear of fall: an open-label randomised controlled trial (YOFEAR trial)

INTRODUCTION

Fear of fall is experienced by the elderly irrespective of the presence or absence of history of fall. Falls contribute to injuries that culminate in hospitalisation that incur unwarranted medical expenses. Yoga is unique to Indian cultural practices, with a potential to enhance proprioception. It increases self-body awareness, ultimately improving the balancing capacity of older adults. Thus, the objective of this study is to compare the effect of yoga therapy in the study and control groups at 12 weeks from the baseline.

METHODS AND ANALYSIS

This study is designed as an open-label, randomised controlled trial (1:1) with a sample size of 62 elderly patients more than or equal to 60 years of age. Participation of either sex, male or female with a fear of fall will be considered. Two randomised groups of 31 participants each will receive standard therapy for their primary diseases as per the local, national or international guidelines. However, participants in the intervention arm will receive additional structured yoga therapy sessions. The primary objective of this study is to assess and compare the change in fear of fall score of participants in each group using Falls Efficacy Scale (FES) and Berg Balance Scale (BBS) at 12 weeks versus baseline. The secondary endpoint will assess the change in the quality of life of participants at 3 months compared with the baseline.Data will be gathered, entered into Microsoft Excel and further analysed by R software (V.4.3.0). Changes in FES-Intervention and BBS of two groups will be compared either by Student's t-test for parametric data or Mann-Whitney U test for non-parametric data. Statistical significance will be considered if p<0.05 at 95% confidence level.

ETHICS AND DISSEMINATION

Ethical approval for this study protocol (version 1.0, 22 April 2022) was obtained from the institute ethics committee (AIIMS/IEC/22/195).

Yoga exercise intervention improves balance control and prevents falls in seniors aged 65+

Introduction

Body balance control represents a key factor preventing falls and subsequent injuries in seniors aged 65+. Intervention based on yoga exercises seem to be effective in improving balance.

Objective

The objective is to analyse and compare changes in static, dynamic, and total balance scores, changes in body composition and social indices as effects of yoga-based intervention.

Methods

A total of 500 participants (234 men aged 74.5 SD±7.74 and 266 women aged 76.9 SD±7.23) were assessed using the Tinetti Balance Assessment Tool, the InBody 230 bioimpedance body composition analyser, and the SF-36 Health Survey, applied to pre and post-testing. The experimental group (n=262; 122 males; 140 females) underwent a four-week yoga-based intervention, 30 minutes daily, while the control group (n=238; 112 males; 126 females) underwent its usual daily programme at senior homes or centres. The ANOVA model, consisting of the Group, Stage, Subject and Group × Stage interaction factors, was used for data evaluation.

Results

Intervention led to improvements in the static, dynamic and total balance scores in the experimental group compared to the control group. The results of SF-36 showed positive changes in the psychosocial aspects of health, such as promoting of calmness and happiness in male seniors and reducing fatigue, nervousness and depression in female seniors. The post-intervention decrease in body fat percentage and increase in muscle mass in seniors is discussed.

Conclusions

The four-week yoga-based intervention had positive effects on the static, dynamic and total balance scores, body composition and social status.

The Effect of Yoga Asana "Vrksasana (Tree Pose)" on Balance in Patients With Postmenopausal Osteoporosis: A Randomized Controlled Trial

OBJECTIVE

In this study, the effect of the add-on effect of the Tree Pose (Vrksasana) on the balance of patients with postmenopausal osteoporosis was investigated.

DESIGN

Thirty-two patients with postmenopausal osteoporosis were randomly assigned to conservative exercise group (30 mins/d for 12 wks) or Tree Pose-added exercise group (30-min conventional exercise + 2-min Tree Pose/d for 12 wks) by Microsoft Excel randomization option. The balance of the patients was evaluated with Berg Balance Scale, Timed Up and Go Test, single-leg standing test, tandem walk test, tandem stance test, and Korebalance static&dynamic balance tests at baseline, sixth week, and third month of the exercise program.

RESULTS

There was no statistically significant difference on baseline data between groups. There was a statistically significant difference between the two groups in the sixth-week measurement of single-leg stance (P < 0.05). In the Berg Balance Scale, static balance test, dynamic balance test, and tandem walk test, a statistically significant difference was found among baseline, sixth-week, and 12th week measurements in both the exercise group and the Tree Pose-added exercise group.

CONCLUSIONS

Gains in the static and dynamic balance of postmenopausal osteoporotic patients can be obtained by adding "Vrksasana" to conventional exercises.

Yoga implications for preventing accidental falls in older adults: a systematic review

Abstract Introduction: Studies have shown the importance of healthy habits in older adults, emphasizing physical activity or mobility for a better quality of life and to delay physical degeneration in this population. Yoga is one of several exercises recommended for therapeutic purposes to reduce the risk of falls, a common occurrence in this age group. Objective: To synthesize the existing evidence regarding the effects of yoga on quality of life and physical-functional capacity and its contribution to fall prevention in older people. Methods: This systematic review was conducted in August 2020 on the Medline/Pubmed, LILACS, SCOPUS, Web of Science and PEDro databases, with no restrictions for language or year of publication. In line with the eligibility criteria, randomized or quasi-randomized clinical trials were included. Results: A total of 1,190 articles were found, 18 of which were included for data collection. The average sample size was between 16 and 120 participants, consisting of older individuals of both sexes ranging in age from 62 to 85 years. Conclusion: Regular yoga practice has a beneficial effect on the quality of life and physical-functional capacity of older adults, thereby contributing to fall prevention. However, evidence is still limited and further studies are suggested to better elucidate the scope of the effects of yoga as a therapeutic resource.

A Systematic Review and Meta-analysis on Efficacy of Exercise on Posture and Balance in Patients Suffering from Diabetic Neuropathy

BACKGROUND

Peripheral neuropathy is a major and chronic complication of diabetes mellitus affecting more than 50% patients suffering from diabetes. There is the involvement of both large and small diameter nerve fibres leading to altered somatosensory and motor sensations, thereby causing impaired balance and postural instability.

OBJECTIVE

The aim of this study is to assess the effects of exercises on posture and balance in patients suffering from diabetes mellitus.

METHODS

Mean changes in Timed Up and Go test (TUGT), Berg Balance Scale and Postural Sway with eyes open and eyes closed on Balance System were primary outcome measures. RevMan 5.3 software was used for the meta-analyses. Eighteen randomized controlled trials met the selection criteria and were included in the study. All the studies ranked high on the PEDro Rating scale. The risk of bias was assessed by the Cochrane collaboration tool of risk of bias. Included studies had a low risk of bias. Sixteen RCT's were included for the meta-analysis.

RESULTS

Results of meta-analysis showed that there was a statistically significant improvement in TUGT with p≤ 0.05 and substantial heterogeneity (I2 = 84%, p < 0.00001) in the experimental group as compared to control group. There was a statistically significant difference in Berg Balance Scale scores and heterogeneity of I2 = 62%, p < 0.00001 and significant changes in postural stability (eyes open heterogeneity of I2 = 100%, p =0.01 and eyes closed, heteogeneity I2 = 0%, p =0.01). Sensitivity analysis causes a change in heterogeneity.

CONCLUSION

It can be concluded that various exercises like balance training, core stability, Tai-Chi, proprioceptive training, etc. have a significant effect on improving balance and posture in diabetic neuropathy.

The effects of a 6-month moderate-intensity Hatha yoga-based training program on health-related fitness in middle-aged sedentary women: a randomized controlled study

BACKGROUND

There is paucity of data examining the effectiveness of long-term Hatha yoga-based (HY) programs focused on the health-related fitness (H-RF) of asymptomatic, sedentary women. The purpose of this study was to examine the effects of a 6-month HY-based training program on H-RF components in sedentary middle-aged women.

METHODS

Eighty sedentary women were randomly assigned into either the HY group (HYG) (N.=42) or the control group (CG) (N.=38). The 6-month HYG program involved a progressive series of Vinyasa Flow poses performed 3 times/week for 60 minutes (40 minutes within the exercise zone of 60-75% HR<inf>max</inf>). The CG participants did not undergo any physical training or education. Health-related fitness parameters included measures of pre- and post-training: body composition, muscular strength and maximal voluntary isometric torques of elbow flexors and knee extensors, cardio-respiratory fitness, lower back and hamstring flexibility and a static-dynamic balance.

RESULTS

Two-way mixed design ANOVA revealed significant main effects for all the indicators of H-RF. Tukey post-hoc tests confirmed that the HYG demonstrated significant improvements in every variable tested. Examples of the benefits achieved include (all P<.001): an average loss of 1.03 kg and a 4.82% decrease in body fat, 14.6% and 13.1% gains in isometric strength of the knee extensors and elbow flexors respectively, an increase in relative VO<inf>2max</inf> of 6.1% (33.12±5.30 to 35.14±4.82 mL/kg/min), a 4-cm or 10.4% increase in their MSAR, and an average improved Balance Index of 5.6 mm/s. Reversely, the CG showed non-significant changes in H-RF variables (all P>0.05; percent range from -1.4% to 1.1%).

CONCLUSIONS

By participating in a moderate-intensity 6-month HY-based training program, middle-aged women can significantly improve their HR-F status. The application of progressive target heart rate goals facilitated greater than expected improvements in cardio-respiratory fitness and improvements in body composition.

Falls and visual impairment among elderly residents in 'homes for the aged' in India

We evaluated the prevalence of falls and their association with visual impairment (VI) in elderly residents in 'homes for the aged' in Hyderabad, India. Participants aged ≥ 60 years were recruited from 41 homes, and a comprehensive eye examination was conducted. Interviews were conducted to collect personal and demographic information, systemic health status, fear of falling, depression, and history of falls in the last year. VI categories included low vision (presenting visual acuity worse than 6/18 to 3/60) and blindness (presenting visual acuity worse than 3/60). The data of 1,074 participants were analysed. The mean age was 74.4 years (standard deviation:8.7 years); 63.9% were women, 19.4% had no formal education, 28.1% were diabetic and 56.9% were hypertensive. The annual prevalence of falls was 29.1% (95% CI: 26.4-32.0). Multivariable analysis showed those with VI had significantly higher odds of falls (Odds Ratio:1.47; p = 0.043). The prevalence of falls was higher among those with VI due to uncorrected refractive errors. We found a very high prevalence of falls in elderly individuals living in 'homes for the aged' in Hyderabad, India. Addressing VI can result in fewer falls and contribute to healthy aging in India.

A 10-week yoga practice has no effect on cognition, but improves balance and motor learning by attenuating brain-derived neurotrophic factor levels in older adults

Despite studies investigating the effect of yoga on cognitive and motor functioning in older adults, the effect on dual-task performance and motor learning and the specific mechanisms underlying the positive effect of yoga remain unclear. Thus, the aim of this study was to investigate the effects of yoga on cognition, balance under single- and dual-task conditions, and motor learning. The potential role of brain-derived neurotrophic factor (BDNF) in induced improvement was also explored. Participants aged 60-79 years were randomized to either a control group (n = 15) or a yoga group (n = 18) for a 10-week period. The yoga group received 90-min duration yoga classes two times per week. Changes in cognition, balance under single- and dual-task conditions, and learning fast and accurate reaching movements were assessed. Yoga practice decreased (P < 0.05) the velocity vector of the center of pressure under single- and dual-task conditions, whereas no changes in cognitive performance were observed. Although reaction and movement times during learning were decreased in both groups (P < 0.05), a faster reaction time (P < 0.05) and shorter movement time (P < 0.05) were observed in the yoga group than in the control group. Significant moderate relationships (P < 0.05) between changes in BDNF levels and functional improvements were observed. Thus, 10 weeks of yoga practice resulted in improved balance and learning in the speed-accuracy motor task that were mediated by increased BDNF levels, but had no impact on cognition in older adults.

[Effects of physical exercise on sleep quality, insomnia, and daytime sleepiness in the elderly. A literature review]

The ageing process alters the stages of sleep, and the elderly that have this problem tend to be prescribed pharmacological treatment. This has long term side effects and results in increased health costs. On the other hand, frequent or regular physical exercise could be an overall superior alternative, due to its multifactorial effects. It is also less expensive, thus more affordable and accessible. Furthermore, these benefits could be extrapolated to the quality of sleep. Taking this into account the purpose of this paper is to establish the proper amount of physical exercise using the FITT (frequency, intensity, time, type of exercise) principle, and its effect on the quality of sleep, insomnia, and daytime sleepiness in the elderly. This could lead us to a paradigm shift in the treatment of sleep disorders, and also may constitute an alternative method for treating the elderly.

Review of health-care services for older population in India and possibility of incorporating AYUSH in public health system for geriatric care

Background:

In a developing country like India, which has 10.11% population of >60 years age and a projection of rise of the same by 300% in 2050, health care of elderly is an enormous challenge. The developed world has evolved many models for elderly care, for example, nursing home care, health insurance, etc. Indian Government has also taken multiple measures in this direction by initiating National Policy on Older Persons, 1999, the Maintenance and Welfare of Parents and Senior Citizens Act, 2007, the Old Age Pension Scheme, Rashtriya Vayoshri Yojana 2017, etc. However, there is a necessity that, India must rapidly adapt to the complex health related, social and economic challenges caused by these demographic changes. This may be an opportunity for innovation in the health system by developing a perspective for healthy and active aging, though it is a major challenge. Health care of the older people cannot be achieved unless total health, i.e., physical, social, economic, psychological, and spiritual aspects are addressed.

Objective:

The objective is to study current policies regarding geriatric health care in India and to propose the possibility to develop a model to provide comprehensive and dedicated health-care services to the older population by integrating conventional and indigenous systems of medicine dwelling in the country.

Materials and methods:

Electronic search in various scientific journals for research and review articles; electronic along with hand searching of conference proceedings, brochures, government policy documents, press releases, Ayurveda classical texts, etc., regarding geriatric health care in India and model health-care facilities in other countries and regarding of AYUSH systems in geriatric health care in India.

Results:

There is an urgent need of adaptation and modification in the National Health System to cater the actual requirements of the elderly with plans and strategies dedicated to face their health-related challenges. Adoption of inclusive health-care interventions, can improve health outcomes by making it more acceptable, accessible, and affordable.

Conclusion:

Integration of AYUSH at various levels of health-care delivery system can potentially contribute to provide unique newer dimensions to the field of geriatric care in India.

Effect of Yoga versus Light Exercise to Improve Well-Being and Promote Healthy Aging among Older Adults in Central India: A Study Protocol for a Randomized Controlled Trial

Background: Aging is a natural process associated with many functional and structural changes. These changes may include impaired self-regulation, changes in tissues and organs. Aging also affects mood, physical status and social activity. There are adverse changes in cognitive behavior, perceived sensation and thinking processes. Regular physical activity can alleviate many health problems; yet, many older adults are inactive. Yoga is one of the scientific and popular lifestyle practice considered as the integration of mind, body and soul. Results of previous studies reported positive effects of yoga on multiple health outcomes in elderly. However, there is scarcity of scientific information where yoga’s effect is examined on over well-being and on multiple health outcomes simultaneously in elderly. This protocol describes methods for a 12-week yoga-based intervention exploring the effects of yoga on well-being in physically inactive elderly living in community. Methods and analysis: This two group parallel single blind randomized controlled trial that will be conducted at a designated facility of R.D. Gardi Medical College, Ujjain, Madhya Pradesh, Central India. A 12-week 60-min yoga intervention three times weekly is designed. Comparison group participants will undergo a 60-min program comprising light exercise focusing on conventional stretching to improve mobility. After screening, 144 participants aged 60–80 years will be recruited. The primary outcome is subjective well-being. Secondary outcomes include mobility, fall risk, cognition, anxiety and depression, mood and stress, sleep quality, pain, physical activity/sedentary behavior and cardio-metabolic risk factors. Assessments will be conducted at baseline (0 week), after the intervention (12+1 week) and at follow-up (36+1 week). Intention-to-treat analyses with mixed linear modeling will be applied. Discussion: Through this trial, we aim to determine whether elderly people in the intervention group practicing yoga show more favorable primary (well-being) and secondary outcomes than those in the light exercise focusing on conventional stretching group. We assume that yoga may be practiced to maintain health, reduce particular symptoms commonly associated with skeletal pain, assist in pain relief and enhance well-being. We anticipate that practicing yoga will improve well-being and mental health and may lead to significant improvement in depression, pain and sleep quality.Ethics and dissemination: This study is approved by the Institutional Ethics Committee of R.D. Gardi Medical College, Ujjain, IEC Ref No. 09/2018. All participants would be provided with written and verbal information about the purpose of the project and would be free to withdraw from the study at any time. Refusal to participate in the study would not have any negative consequences. Confidentiality of the information of each participant would be ensured. Knowledge obtained would be disseminated to stakeholders through workshops, meetings and relevant scientific conferences.Trial Registration: The trial is prospectively registered with the Indian Council of Medical Research Trial Registry CTRI/2018/07/015051.

Circuit Training Improvements in Korean Women with Sarcopenia

Sarcopenia is defined as an age-related decrease in muscle mass, strength, and function. We investigated the effect of circuit training on body composition, balance, muscle mass and strength, and pulmonary function in Korean women with sarcopenia. We randomly assigned 26 Korean women with sarcopenia (M_age = 74.9, SD = 4.5 years) to either an exercise group (EG) (n = 13) or a control group (CG) (n = 13). The EG performed 25-75 minutes of circuit exercise training (gradually increasing time periods) three times per week over 12 weeks, while the CG maintained their usual daily lifestyle during the intervention period. We measured body weight, body mass index, percent body fat, free fat mass, balance ability, peak torque in shoulder, knee, and lumbar joints normalized for bodyweight (BW), forced vital capacity, percentage of forced expiratory volume in one second, and forced expiratory flow 25-75% before and after the intervention. The EG showed improved body composition (i.e., body mass index, fat-free body mass, fat mass; all p < .032, η²> 0.180), balance (i.e., right and left of static and dynamic balance and fast 10-m walk; all p < .050, η²> 0.151), muscular function (i.e., 90°/s and 180°/s peak power per kilogram BW, 90°/s average power per kilogram BW, 180°/s total work, and 180°/s endurance ratio; all p < .045, η²> 0.157), and pulmonary function (all p < .005, η²> 0.292). On the other hand, the CG showed no significant changes. Circuit exercise training improves muscle mass and strength, body composition, balance, and pulmonary function in women with sarcopenia.

Effects of yoga on well-being and healthy ageing: study protocol for a randomised controlled trial (FitForAge)

INTRODUCTION

Due to ageing populations worldwide, the burden of disability is increasing. It is therefore important to develop interventions that improve healthy ageing, reduce disability onset and enhance life quality. Physical activity can promote healthy ageing and help maintain independence, yet many older adults are inactive. Yoga is a form of physical activity that aims to improve health and may be particularly suitable for older adults. Research indicates positive effects of yoga on several health-related outcomes; however, empirical studies examining the benefits of yoga on well-being among the elderly remain scarce. This study protocol reports the methodology for a 12-week yoga programme aimed to improve health and well-being among physically inactive older adults.

METHODS AND ANALYSIS

Three group parallel, single-blind randomised controlled trial. Two comparison groups are included: aerobic exercise and a non-active wait-list control. In total, 180 participants aged 65-85 years will be recruited. Assessments will be performed at baseline and postintervention (12-week follow-up). The primary outcome is subjective well-being. Secondary outcomes include physical activity/sedentary behaviour, mobility/fall risk, cognition, depression, anxiety, mood, stress, pain, sleep quality, social support and cardiometabolic risk factors. Data will be analysed using intention-to-treat analyses, with mixed linear modelling.

ETHICS AND DISSEMINATION

This study is approved by the Ethical Review Board in Stockholm (2017/1862-31/2). All participants must voluntarily agree to participate and are free to withdraw from the study at any point. Written informed consent will be obtained from each participant prior to inclusion. Results will be available through research articles and conferences. A summary of key results will be publicly available through newspaper articles.

Are interventions effective in improving the ability of older adults to rise from the floor independently? A mixed method systematic review

Purpose: To review available evidence on older people's ability to get up off the floor independently and determine the effectiveness of interventions to improve older adults' ability to rise from the floor.Materials and methods: Seven databases were searched between January 1975 and June 2018. Eligibility criteria included: people aged ≥60; interventions to improve strength/function including ability to get up off the floor (for intervention studies); comparison groups (for randomized and nonrandomized controlled trials); outcome: quantitative or qualitative evaluation of ability to get up off the floor. Selection of the studies was undertaken in three stages: (1) titles and abstracts were scanned by one reviewer, (2) full abstract screening by one reviewer, and (3) articles read in full by two reviewers. Results of all articles are summarized and randomized controlled trials (RCT) (where possible) were analyzed by meta-analysis to determine intervention effectiveness.Results: Forty-one studies met inclusion criteria. For each of the RCTs that utilized resistance training and/or teaching the skill, a reduction in time to get up off the floor were reported. However, meta-analyses of all RCT interventions indicated no significant change in time for older people to get up off the floor independently with intervention (MD: -0.43[-1.38, 0.51]). Sub-analyses of interventions utilizing resistance training showed an improvement trending towards significance (MD: -0.81[-1.72, 0.09]). Heterogeneity between studies was high, therefore results should be viewed with some caution.Conclusions: Resistance training interventions may improve older people's ability to rise from the floor unassisted. However, knowledge of specific techniques to get up and the effect of simply practicing the task of getting off the floor need to be further explored.Implication for rehabilitationOne in three older people living in the community fall each yearOne aspect of falling that is often overlooked is whether the older person can get themselves up off the floor independently or do they have to wait for assistance.Interventions that include resistance training may help the older person to be able to get up by themselves.

A Pilot Study of Iyengar Yoga for Pediatric Obesity: Effects on Gait and Emotional Functioning

Obesity negatively impacts the kinematics and kinetics of the lower extremities in children and adolescents. Although yoga has the potential to provide several distinct benefits for children with obesity, this is the first study to examine the benefits of yoga for gait (primary outcome) in youths with obesity. Secondary outcomes included health-related quality of life (HRQoL), physical activity, and pain. Feasibility and acceptability were also assessed. Nine youths (11⁻17 years) participated in an eight-week Iyengar yoga intervention (bi-weekly 1-h classes). Gait, HRQOL (self and parent-proxy reports), and physical activity were assessed at baseline and post-yoga. Pain was self-reported at the beginning of each class. Significant improvements were found in multiple gait parameters, including hip, knee, and ankle motion and moments. Self-reported and parent-proxy reports of emotional functioning significantly improved. Time spent in physical activity and weight did not change. This study demonstrates that a relatively brief, non-invasive Iyengar yoga intervention can result in improved malalignment of the lower extremities during ambulation, as well as in clinically meaningful improvements in emotional functioning. This study extends current evidence that supports a role for yoga in pediatric obesity.

Effects of chair yoga therapy on physical fitness in patients with psychiatric disorders: A 12-week single-blind randomized controlled trial

INTRODUCTION

Since falls may lead to fractures and have serious, potentially fatal outcomes, prevention of falls is an urgent public health issue. We examined the effects of chair yoga therapy on physical fitness among psychiatric patients in order to reduce the risk of falls, which has not been previously reported in the literature.

METHODS

In this 12-week single-blind randomized controlled trial with a 6-week follow-up, inpatients with mixed psychiatric diagnoses were randomly assigned to either chair yoga therapy in addition to ongoing treatment, or treatment-as-usual. Chair yoga therapy was conducted as twice-weekly 20-min sessions over 12 weeks. Assessments included anteflexion in sitting, degree of muscle strength, and Modified Falls Efficacy Scale (MFES) as well as QOL, psychopathology and functioning.

RESULTS

Fifty-six inpatients participated in this study (36 men; mean ± SD age, 55.3 ± 13.7 years; schizophrenia 87.5%). In the chair yoga group, significant improvements were observed in flexibility, hand-grip, lower limb muscle endurance, and MFES at week 12 (mean ± SD: 55.1 ± 16.6 to 67.2 ± 14.0 cm, 23.6 ± 10.6 to 26.8 ± 9.7 kg, 4.9 ± 4.0 to 7.0 ± 3.9 kg, and 114.9 ± 29.2 to 134.1 ± 11.6, respectively). Additionally, these improvements were observable six weeks after the intervention was over. The QOL-VAS improved in the intervention group while no differences were noted in psychopathology and functioning between the groups. The intervention appeared to be highly tolerable without any notable adverse effects.

CONCLUSIONS

The results indicated sustainable effects of 20-min, 12-week, 24-session chair yoga therapy on physical fitness. Chair yoga therapy may contribute to reduce the risk of falls and their unwanted consequences in psychiatric patients.

The Utility of the Supine-to-Stand Test as a Measure of Functional Motor Competence in Children Aged 5⁻9 Years

This study examined how supine-to-stand (STS) performance is related to process and product assessment of motor competence (MC) in children. Ninety-one children aged 5⁻9 years were assessed for process and product MC (10 m running speed and standing long jump) as well as process and product measures of STS. Tertiles were created for STS process and STS product scores to create 3 groups reflecting low, medium, and high STS competency. ANCOVA analysis, controlling for age, for process STS, indicated that process MC was significantly higher in children, classified as medium STS (p = 0.048) and high STS (p = 0.011) competence, and that 10 m run speed was slower for low STS compared to medium (p = 0.019) and high STS (p = 0.004). For product STS tertiles, process MC was significantly higher for children in the lowest (fastest) STS tertile compared to those in the medium highest (slowest) tertile (p = 0.01).

Evidence based effects of yoga practice on various health related problems of elderly people: A review

More than 50% of the elderly above 60 years of age suffer from chronic medical conditions, the prevalence of which increases with age. Though Yoga has been reported as an effective modality in improving various physical and psychological aspects of elderly populations, a comprehensive review of Yoga and its effects on various health related problems of elderly populations has not yet been reported. Hence, we performed PubMed/Medline search to review relevant articles, using keyword "yoga and elderly". Relevant articles published since inception till 6th October 2016 were included for the review. Based on the available scientific literature, this review suggests that the regular practice of Yoga can be considered as an effective intervention in improving physical (reduces heart rate, blood pressure, blood glucose, oxidative damage, fatigue, weakness, fear of fall, and improve heart rate variability, baroreflex sensitivity, insulin sensitivity, physical functions, mobility, flexibility, and urinary incontinence), mental (reduces depression, anxiety), emotional (reduces anger, stress, tension and improve self-efficacy), social (improve life satisfaction), and vital (improved vitality) planes of elderly individuals, offering a better quality of sleep and quality of life.

Physical-Performance Outcomes and Biomechanical Correlates from the 32-Week Yoga Empowers Seniors Study

Background. Yoga Empowers Seniors Study (YESS) quantified physical demands associated with yoga performance using biomechanical methods. This study evaluated the efficacy of the program on physical function outcomes. Methods. Twenty community-dwelling older adults aged 70.7 ± 3.8 years attended biweekly 60-minute Hatha yoga classes for 32 weeks. Four domains of the physical measurements including (1) functional performance, (2) flexibility, (3) muscle strength, and (4) balance were taken at the baseline, 16-week and 32-week time points. Repeated-measures ANOVA omnibus tests and Tukey's post hoc tests were employed to examine the differences in each outcome variable across the 3 time points. Results. Improved timed chair stands (p < 0.01), 8-foot up and go (p < 0.05), 2-min step test (p < 0.05), and vertical reach (p = 0.05) performance were evident. Isometric knee flexor strength (p < 0.05) and repetitions of the heel rise test (p < 0.001) also increased following the 32-week intervention. Both flexibility and balance performance remained unchanged. Conclusions. Significant improvements in physical function and muscle-specific lower-extremity strength occur with the regular practice of a modified Hatha yoga program designed for seniors. These adaptations corresponded with the previously reported biomechanical demands of the poses.

Mind-Body Exercises for Nurses with Chronic Low Back Pain: An Evidence-Based Review

Background. Chronic low back pain (CLBP) among nurses is a growing health concern. The multimodal nature of mind-body exercises has potential to impact physiological and psychological processes associated with chronic pain, affording possible advantages over conventional unimodal therapies. This paper summarizes the prevalence of and risk factors for CLBP among nurses, reviews the effectiveness in treating pain and disability of mind-body exercises (yoga and tai chi) for CLBP among the general and nursing population, and describes implications. Methods. Articles, published during or prior to 2015, were systematically identified through the PubMed/MEDLINE, Web of Science, and ScienceDirect databases using the following search terms: nurses, mind-body, integrative, biopsychosocial, yoga, tai chi, back pain, and/or risk factors. Results. Prevalence estimates of CLBP among nurses ranged from 50% to 80%. Associated risk factors for CLBP included lifestyle and physical, psychological, psychosocial, and occupational factors. No published studies were identified that evaluated yoga or tai chi for nurses with CLBP. Studies in the general population suggested that these interventions are effective in reducing pain and disability and may improve factors/processes predictive of CLBP. Conclusion. This review suggests that evaluating the impact of multimodal interventions such as yoga and tai chi for nurses with CLBP warrants investigation.

Yoga reduces perceived stress and exhaustion levels in healthy elderly individuals

This study investigated whether a 7-week yoga intervention could improve physical function, perceived stress, and mental/emotional wellness in elderly participants.

METHODS

8 participants (66.5 ± 0.3 years) attended 2 60-min Hatha yoga sessions/week for 7 weeks, and performed pre- and post-intervention assessments. Balance was assessed using a 5-test battery. Flexibility was measured by sit-and-reach and shoulder flexibility tests. Functional mobility tests included 8-ft up-and-go, 5 chair stands, and 4-m walk. Participants completed SF-12, exhaustion level, and Perceived Stress Scale (PSS) questionnaires.

RESULTS

SF-12 Mental Component Summary scores, exhaustion levels, and PSS scores improved post-intervention. No differences were found for physical function measures.

CONCLUSIONS

Yoga participation can improve mental/emotional wellness, exhaustion levels, and stress levels in elderly individuals, even without measurable improvements in physical function. Clinicians and health practitioners who work with the elderly should consider yoga as a potential therapeutic modality for improving important aspects of quality of life in this population.

The effects of a therapeutic yoga program on postural control, mobility, and gait speed in community-dwelling older adults

OBJECTIVE

To examine the effects of a 12-week therapeutic yoga program on gait speed, postural control, and mobility in community-dwelling older adults.

DESIGN

Quasi-experimental study with a pretest/post-test design. Researchers evaluated changes over time (pretest to post-test) in all outcome measures. Paired t-tests were used to analyze normal and fast gait speed, Timed Up and Go test, and Timed Up and Go Dual Task. Wilcoxon signed-rank test was used to evaluate scores for the Mini-BESTest (MBT).

SETTING

Yoga classes were performed at a local senior center. Blind examiners who were previously trained in the outcome measures performed all pretests and post-tests at the site.

PARTICIPANTS

Thirteen adults (12 women and 1 man, with a mean age±standard deviation of 72±6.9 years) completed the study. Research participants had minimal to no yoga experience.

INTERVENTIONS

A 12-week, 60-minute, biweekly Kripalu yoga class designed specifically for community-dwelling older adults.

OUTCOME MEASURES

Postural control (MBT), mobility (Timed Up and Go test), and gait speed (normal and fast) were assessed.

RESULTS

All 13 participants attended at least 19 of the 24 classes (80% attendance). Statistically significant improvements were seen in the MBT (p=0.039), normal gait speed (p=0.015), fast gait speed (p=0.001), Timed Up and Go test (p=0.045), and Timed Up and Go Dual-Task (p=0.05).

CONCLUSIONS

Improvements in postural control and mobility as measured by the MBT and Timed Up and Go gait as measured by fast gait speed indicate that research participants benefitted from the therapeutic yoga intervention. The yoga program designed for this study included activities in standing, sitting, and lying on the floor and may be effective in improving mobility, postural control, and gait speed in community-dwelling older adults.

Yoga for correction of lymphedema's impairment of gait as an adjunct to lymphatic drainage: A pilot observational study

INTRODUCTION

Yoga used as a major component of integrative treatment protocol in 14 Indian village camps improved quality-of-life in 425 lymphatic filariasis patients. They experienced better mobility and reduced disability. This paper documents the gait abnormalities observed in lower limb lymphedema patients and the locomotor changes following integrative treatment.

MATERIALS AND METHODS

Yoga postures were performed as explained by traditional yoga practice in two sessions: Before ayurvedic oil massage without compression bandages and after the massage with compression bandages. Each yoga posture lasted for 5 min and the whole session ended in 45 min. Throughout each session, we advised patients to do long, diaphragmatic breathing, concentrating on each breath. The flexion of joints was coordinated with exhalation and extension with inhalation. We educated the patients to do longer expiration than inspiration.

RESULTS AND DISCUSSION

A total of 98 patients (133 limbs) attending the 6(th) month follow-up were evaluated. The most common gait abnormality was antalgic gait. Structural and functional abnormalities were observed in hip, knee and ankle joints. We found that yoga as an adjunct to other components in integrative treatment improved the gait problems. Long standing lymphedema caused altered gait and joint deformities. This was mostly due to inactivity causing muscle weakness and edema within and around the muscles. Both large and small limbs have shown significant volume reduction (P < 0.01) during follow-up after 6 months.

CONCLUSION

There can be a mixed etiology for gait related problems in lymphedema patients. Further studies are recommended to understand the causes of deformities in lymphedema patients and an exact role of yoga.

Twelve weeks of BodyBalance® training improved balance and functional task performance in middle-aged and older adults

Purpose

The purpose of the study was to evaluate the effect of BodyBalance^® training on balance, functional task performance, fear of falling, and health-related quality of life in adults aged over 55 years.

Participants and methods

A total of 28 healthy, active adults aged 66±5 years completed the randomized controlled trial. Balance, functional task performance, fear of falling, and self-reported quality of life were assessed at baseline and after 12 weeks. Participants either undertook two sessions of BodyBalance per week for 12 weeks (n=15) or continued with their normal activities (n=13).

Results

Significant group-by-time interactions were found for the timed up and go (P=0.038), 30-second chair stand (P=0.037), and mediolateral center-of-pressure range in narrow stance with eyes closed (P=0.017). There were no significant effects on fear of falling or self-reported quality of life.

Conclusion

Twelve weeks of BodyBalance training is effective at improving certain balance and functional based tasks in healthy older adults.

The influence of tai chi and yoga on balance and falls in a residential care setting: a randomised controlled trial

Abstract Falls amongst older people is a global public health concern. Whilst falling is not a typical feature of ageing, older people are more likely to fall. Fall injuries amongst older people are a leading cause of death and disability. Many older people do not do regular exercise so that they lose muscle tone, strength, and flexibility which affect balance and predispose them to falls. The management of falls in residential care settings is a major concern with strategies for prevention and monitoring a focus in this setting. Yoga and tai chi have shown potential to improve balance and prevent falls in older adults. They also have potential to improve pain and quality of life. The aim of this study was to determine the feasibility of conducting a 3-arm RCT with frail older people in a residential care setting to test the hypothesis that a 14 week modified tai chi or yoga program is more effective than usual care activity in improving balance function, quality of life, pain experience and in reducing number of falls. There were no statistically significant differences between the three groups in the occurrence of falls. Yoga demonstrated a slight decrease in fall incidence; quality of life improved for the tai chi group. Only the yoga group experienced a reduction in average pain scores though not statistically significant. The findings of the study suggest it is possible to safely implement modified yoga and tai chi in a residential care setting and evaluate this using RCT design. They show positive changes to balance, pain and quality of life and a high level of interest through attendance amongst the older participants. The results support offering tai chi and yoga to older people who are frail and dependent with physical and cognitive limitations.

A systematic review of yoga for balance in a healthy population

OBJECTIVE

A systematic review was done of the evidence on yoga for improving balance.

DESIGN

Relevant articles and reviews were identified in major databases (PubMed, MEDLINE(®), IndMed, Web of Knowledge, EMBASE, EBSCO, Science Direct, and Google Scholar), and their reference lists searched. Key search words were yoga, balance, proprioception, falling, fear of falling, and falls. Included studies were peer-reviewed articles published in English before June 2012, using healthy populations. All yoga styles and study designs were included. Two (2) raters individually rated study quality using the Downs & Black (DB) checklist. Final scores were achieved by consensus. Achievable scores ranged from 0 to 27. Effect size (ES) was calculated where possible.

RESULTS

Fifteen (15) of 152 studies (age range 10-93, n=688) met the inclusion criteria: 5 randomized controlled trials (RCTs), 4 quasi-experimental, 2 cross-sectional, and 4 single-group designs. DB scores ranged from 10 to 24 (RCTs), 14-19 (quasi-experimental), 6-12 (cross-sectional), and 11-20 (single group). Studies varied by yoga style, frequency of practice, and duration. Eleven (11) studies found positive results (p<0.05) on at least one balance outcome. ES ranged from -0.765 to 2.71 (for 8 studies) and was not associated with DB score.

CONCLUSIONS

Yoga may have a beneficial effect on balance, but variable study design and poor reporting quality obscure the results. Balance as an outcome is underutilized, and more probing measures are needed.

Interventions to maintain mobility: What works?

Mobility, in broad terms, includes everything from the ability to move within your immediate environment (e.g., get out of bed) to the ability to drive across the country. Mobility is essential to maintaining independence and wellbeing, particularly for older adults. This is highlighted by the large number of interventions developed for older adults with the goal of maintaining such mobility. The current paper reviews the state of the science with respect to mobility interventions. Inclusion criteria for the review were: (1) articles must have been peer-reviewed; (2) interventions were evaluated in a randomized controlled trial (RCT); (3) studies included a mobility outcome such as lifespace, driving, or walking ability; (4) studies included a sample of healthy community-dwelling older adults (e.g., not investigations of disease conditions); and (5) studies must have reported enough empirical data and detail such that results could potentially be replicated. Three main types of interventions were identified: cognitive training, educational interventions, and exercise interventions. A detailed summary and evaluation of each type of intervention, and the current evidence regarding its effectiveness in maintaining mobility, are discussed. Several interventions show clear evidence of effectiveness, and thus are prime areas for translation of results to the older population. Needs and issues for future intervention research are also detailed.

Effects of yoga therapy on postural stability in patients with schizophrenia-spectrum disorders: a single-blind randomized controlled trial

INTRODUCTION

Postural instability is a serious concern in patients with schizophrenia-spectrum disorders since it is expected to increase the risk of falls that may lead to fractures. The impact of yoga therapy on postural stability has not been investigated.

METHODS

In this eight-week single-blind randomized controlled study with an eight-week follow-up, outpatients with schizophrenia or related psychotic disorder (ICD-10) were randomly assigned to either yoga therapy or a control group. In the yoga therapy group, the subjects received weekly sessions of 60-min yoga therapy for eight weeks in addition to their ongoing treatment. In the control group, the subjects received a weekly regular day-care program. The assessments that were performed at the baseline and endpoint included the Clinical Stabilometric Platform (CSP), anteflexion in standing.

RESULTS

Forty-nine patients participated in this study (32 men; mean ± SD age, 53.1 ± 12.3 years): yoga therapy group (n = 25) and control group (n = 24). In the yoga group, significant improvements were observed in a total length of trunk motion, the Romberg ratio, and anteflexion in standing at week 8 (mean ± SD: 63.9 ± 40.7-53.4 ± 26.2 cm, 1.6 ± 0.9-1.1 ± 0.6, and -8.7 ± 9.5 to -3.8 ± 12.4 cm, respectively) while there were no significant changes in the control group. However, those clinical gains returned to the baseline level at week 16.

CONCLUSIONS

The results confirmed the beneficial effects of the yoga therapy on postural stability in patients with schizophrenia. However, the therapeutic effects seemed transient, which warrants further investigations on strategies to sustain the improvements.

Effects of yoga intervention on sleep and quality-of-life in elderly: A randomized controlled trial

CONTEXT

Yoga as a life-style practice has demonstrated beneficial effects. The role of yoga in the elderly for such benefits merits investigation.

AIMS

The aim of this study is to examine the effects of yoga intervention on quality-of-life (QOL) and sleep quality in the elderly living in old age homes.

SETTINGS AND DESIGN

Single blind controlled study with block randomization of elderly homes.

MATERIALS AND METHODS

A total of 120 subjects from nine elderly homes were randomized in to yoga group (n=62) and waitlist group (n=58). Subjects in the yoga group were given yoga intervention daily for 1 month and weekly until 3 months and were encouraged to practice yoga without supervision until for 6 months. Subjects in waitlist group received no intervention during this period. Subjects were evaluated with World Health Organization Quality of Life (WHOQOL)-BREF for measuring QOL and Pittsburgh Sleep Quality Index for sleep quality in the baseline and after 6 months.

STATISTICAL ANALYSIS

Independent t-test and repeated measures analysis of covariance respectively was used to measure the difference in outcome measures between the two groups at baseline and after the study period.

RESULTS

Subjects in the yoga group had significantly higher number of years of formal education. Subjects in the yoga group had significant improvement in all the domains of QOL and total sleep quality after controlling for the effect of baseline difference in education between the two groups.

CONCLUSION

Yoga intervention appears to improve the QOL and sleep quality of elderly living in old age homes. There is a need for further studies overcoming the limitations in this study to confirm the benefits of yoga for elderly in QOL and sleep quality.

Designing, validation and feasibility of a yoga-based intervention for elderly

CONTEXT

Ageing is an unavoidable facet of life. Yogic practices have been reported to promote healthy aging. Previous studies have used either yoga therapy interventions derived from a particular school of yoga or have tested specific yogic practices like meditation.

AIMS

This study reports the development, validation and feasibility of a yoga-based intervention for elderly with or without mild cognitive impairment.

SETTINGS AND DESIGN

The study was conducted at the Advanced Centre for Yoga, National Institute for Mental Health and Neurosciences, Bangalore. The module was developed, validated, and then pilot-tested on volunteers.

MATERIALS AND METHODS

The first part of the study consisted of designing of a yoga module based on traditional and contemporary yogic literature. This yoga module along with the three case vignettes of elderly with cognitive impairment were sent to 10 yoga experts to help develop the intended yoga-based intervention. In the second part, the feasibility of the developed yoga-based intervention was tested.

RESULTS

Experts (n=10) opined the yoga-based intervention will be useful in improving cognition in elderly, but with some modifications. Frequent supervised yoga sessions, regular follow-ups, addition/deletion/modifications of yoga postures were some of the suggestions. Ten elderly consented and eight completed the pilot testing of the intervention. All of them were able to perform most of the Sukṣmavyayāma, Prāṇāyāma and Nādānusaṇdhāna (meditation) technique without difficulty. Some of the participants (n=3) experienced difficulty in performing postures seated on the ground. Most of the older adults experienced difficulty in remembering and completing entire sequence of yoga-based intervention independently.

CONCLUSIONS

The yoga based intervention is feasible in the elderly with cognitive impairment. Testing with a larger sample of older adults is warranted.

Yoga Empowers Seniors Study (YESS): Design and Asana Series

The practice of yoga asanas (postures) may be an optimal method of preserving or enhancing physical function in older men and women. However, the physical demands, efficacy and safety of an asana practice for seniors have not been well studied. The Yoga Empowers Seniors Study (YESS) is an intervention development study that created two senior-adapted series of asanas targeted for an ambulatory older population. YESS is using biomechanics and physical performance tests to acquire information about the physical demands placed on the muscles and joints by the asanas and the functional performance adaptations resulting from the yoga practice. This manuscript details the standardized, senior-adapted, YESS asana series and the additional asana modifications provided when participants had physical limitations. This presentation will enable the yoga research and teaching communities to interpret the biomechanics, physical performance and side effects outcomes of YESS.
