A Pilot Study of the Effects of Chair Yoga and Chair-Based Exercise on Biopsychosocial Outcomes in Older Adults With Lower Extremity Osteoarthritis

Key characteristics of effective yoga interventions for managing osteoarthritis: a systematic review and meta-analysis

This systematic review aimed to synthesise the content, structure, and delivery characteristics of effective yoga interventions for managing osteoarthritis symptoms, including joint pain and joint function. JBI guidelines were followed. 17 databases were searched for randomised controlled trials (RCTs) assessing yoga's effectiveness on osteoarthritis symptoms. Meta-analyses and a narrative synthesis were conducted to address the objective. The systematic review and meta-analysis included 18 and 16 articles (representing 16 and 14 RCTs), respectively. Overall, the included studies had low methodological quality scores. 10 of 14 yoga interventions effectively reduced pain (standardised mean difference (SMD) - 0.70; 95% confidence interval (CI) - 1.08, - 0.32) and/or improved function (- 0.40; - 0.75, - 0.04). Notably, 8 effective interventions had centre-based (supervised, group) sessions, and 6 included additional home-based (unsupervised, individual) sessions. Effective interventions included 34 yogic poses (12 sitting, 10 standing, 8 supine, 4 prone), 8 breathing practices, and 3 meditation and relaxation practices. 8 interventions included yogic poses, and 7 also incorporated breathing practices and/or meditation and relaxation practices. 4 interventions included yogic pose modifications for osteoarthritis. The median duration of centre-based sessions was 8 weeks and each session was around 53 min, mostly delivered once a week. The median duration of home-based sessions was 10 weeks and each session was 30 min, usually instructed to practice 4 times a week. Given previous studies' limitations, a high-quality long-term RCT should be conducted using synthesised findings of previous effective yoga interventions.

Holistic frailty prevention: The promise of movement-based mind-body therapies

Aging is characterized by fundamental cellular and molecular hallmarks that result in physiologic decline of most body systems. This may culminate in frailty, a state of decreased reserve. Because frailty is a state of multisystem dysregulation, multimodal interventions may be necessary to mitigate and prevent progression rather than interventions targeting a single system. Movement-based mind-body therapies, such as tai chi and yoga, are promising multimodal strategies for frailty prevention and treatment given their inherent multicomponent nature. In this review, we summarize the links between hallmarks of aging and frailty and how tai chi and yoga may impact these hallmarks. We review trial evidence for the impact of tai chi and yoga on frailty in older populations and discuss opportunities for future research.

A Chair-Based Music-Kinetic Combined Exercise Program as an Alternative Approach for Increasing Health, Functional Capacity, and Physical Fitness Indices in Middle-Aged Pre-Menopausal Women

Lately, chairs have been widely used as a cheap, easily accessible, safe, and effective training means in different settings (e.g., in gyms, the house, workplaces, and in rehabilitation). This study investigated the effectiveness of a 10-week chair-based music-kinetic integrated combined exercise program on health, functional capacity, and physical fitness indicators of middle-aged pre-menopausal women. A total of 40 healthy women (40-53 years) were assigned to two groups: exercise (EG) and control (CG). The EG followed a 10-week (3 times/weekly; 30 training sessions) chair-based exercise program including aerobic dance, flexibility, coordination, and strength exercises with body weight or auxiliary means. Selected indicators of health, functional capacity, and physical fitness were evaluated before and after the 10 weeks. Following the program, the EG significantly reduced their body fat (-2.5%), blood pressure (by -4.5 to -5.5%), the time during the timed up-and-go (TUG) test (by -10.27%), heart rate (by -6.35 to -13.78%), and the rate of perceived exertion (by -24.45 to -25.88%), while increasing respiratory function (3.5-4%), flexibility (12.17%), balance (50.38-51.07%), maximal handgrip strength (10-12.17%), and endurance strength (43.87-55.91%). The chair-based combined music-kinetic exercise program was effective and could be safely used in different settings to improve health, functional capacity, and physical fitness in middle-aged women.

Effect of Yoga on Frailty in Older Adults : A Systematic Review

BACKGROUND

Yoga, a multicomponent mind-body practice, improves several domains of physical and psychological health and may affect frailty in older adults.

PURPOSE

To evaluate the available trial evidence on the effect of yoga-based interventions on frailty in older adults.

DATA SOURCES

MEDLINE, EMBASE, and Cochrane Central from their inception to 12 December 2022.

STUDY SELECTION

Randomized controlled trials evaluating the effect of yoga-based interventions, including at least 1 session of physical postures, on a validated frailty scale or single-item markers of frailty in adults aged 65 years or older.

DATA EXTRACTION

Two authors independently screened articles and extracted data; 1 author assessed risk of bias with review from a second author. Disagreements were resolved through consensus and as-needed input from a third author.

DATA SYNTHESIS

Thirty-three studies (n = 2384 participants) were identified in varied populations, including community dwellers, nursing home residents, and those with chronic disease. Yoga styles were primarily based on Hatha yoga and most often included Iyengar or chair-based methods. Single-item frailty markers included measures of gait speed, handgrip strength, balance, lower-extremity strength and endurance, and multicomponent physical performance measures; no studies included a validated definition of frailty. When compared with education or inactive control, there was moderate-certainty evidence that yoga improved gait speed and lower-extremity strength and endurance, low-certainty evidence for balance and multicomponent physical function measures, and very low-certainty evidence for handgrip strength.

LIMITATION

Heterogeneity in study design and yoga style, small sample sizes, and reporting deficiencies leading to concerns for selection bias.

CONCLUSION

Yoga may affect frailty markers that are associated with clinically meaningful outcomes in older adult populations but may not offer benefit over active interventions (for example, exercise).

PRIMARY FUNDING SOURCE

None. (PROSPERO: CRD42020130303).

Comparing the Effects of Virtual Reality and Home Chair-Based Exercises on Balance, Daily Living Activities, and Loneliness Among Older Adults With Balance Disorders

The current quasi-experimental study aimed to compare the effects of virtual reality (VR) and home chair-based (HCB) exercises on balance, daily living activities, and loneliness among older adults (N = 90) with balance disorders living in nursing homes. Participants were assigned to three groups: (a) VR exercises, (b) HCB exercises, and (c) routine nursing home programs. Findings indicated that VR and HCB exercises significantly increased participants' balance and daily living activities compared to routine programs (p < 0.001). However, there was no clinical difference among groups regarding Berg Balance Scale and Barthel Index scores. Main effect of time regarding loneliness mean score (p = 0.991) was not significant among groups. The minimal detectable change pre-set standard for loneliness also showed no significant clinical difference. Exercise had no significant impact on loneliness; however, it had a positive role in improving balance and daily living activities, with no significant difference between VR and HCB exercises. Further studies are recommended to evaluate adherence to such exercises. [Research in Gerontological Nursing, 16(1), 33-42.].

Research study on the effects of multi-component exercise on older adults with chronic conditions

BACKGROUND

Multicomponent exercises involving eccentric contraction (ECC) exercise, chair yoga (CY) and tai chi (TC) are practiced extensively to treat older adults with chronic conditions. The study investigated the effect of CY and TC performance after various intensity of ECC exercise induced muscle pain, delayed onset of muscle sores (DOMS), and strength in sedentary older adults.

METHODS

Nine sedentary older adults with chronic condition(s) aged between 60 and 90 performed CY and TC after ECC exercise protocol for 9 weeks. The medical preprotocol, ECC exercise, CY, and TC performance, subjective (health activities of daily living [ADL] difficulty scale; Visual Analog Scale [VAS], and DOMS), objective (pressure pain threshold [PPT]), and medical postprotocol assessments were carried out and compared the physical status before and after the protocol.

RESULTS

Our results show that functional limitations, DOMS, VAS, and PPT levels were improved in the CY and TC performed weeks 3, 4, 7, and 8 compared to ECC exercise weeks 2 and 6. The manual muscle testing (MMT), active range of motion (AROM), and maximal voluntary isometric contraction (MVIC) were improved and showed significant differences on the weak muscle groups. The mean Tinetti balance and gait score, and general endurance showed significant difference.

CONCLUSIONS

Our findings have important implications for clinical exercise prescription as low perceived CY and TC, and ECC exercise might suit well for older adults with chronic conditions. Performing multicomponent exercises can help to reduce the risk of injury from falls and prevent age-related mobility, balance, and physical function decline in older adults.

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.
