Multimodal Exercise Effects in Older Adults Depend on Sleep, Movement Biography, and Habitual Physical Activity: A Randomized Controlled Trial

Efficacy of non-pharmacological interventions for sleep quality in Parkinson's disease: a systematic review and network meta-analysis

Background

Sleep disorders are one of the most common non-motor symptoms in PD. It can cause a notable decrease in quality of life and functioning in PD patients, as well as place a huge burden on both patients and caregivers. Currently, there are numerous non-pharmacological interventions available to improve sleep quality in PD, with disagreement as to which intervention is most effective. This network meta-analysis was performed to compare and rank non-pharmacological interventions to explore their efficacy in improving sleep quality in PD and to select the best interventions, with a view to providing references and bases for the development of clinical treatments and care programs.

Methods

The PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang databases were searched from inception to December 6, 2023. Two authors independently screened all studies, extracted the data, and evaluated risk of bias of included studies. STATA software version 17.0 was used to conduct the network meta-analysis.

Results

Our network meta-analysis included 29 studies involving 1,477 participants and 16 non-pharmacological interventions. Although most nonpharmacological interventions showed non-significant effects, the surface under the cumulative ranking curve (SUCRA) values indicated that the best non-pharmacological intervention for sleep disorders was massage therapy (97.3%), followed by music therapy (94.2%), and Treadmill training (85.7%).

Conclusion

Massage therapy can be considered as an effective therapy for improving sleep quality in patients with PD. Due to limited quantity and quality of the included studies, more high quality studies are required to verify the conclusions of this network meta-analysis.

Psychometric Properties of the Falls Efficacy Scale-International, Cut-off Points, and Validating its Short Version Among Iranian Older People

Objectives

Older people have a fear of falling, which is far more difficult than falling itself. We measured the extent of this feeling using a short and valid Falls Efficacy Scale-International (FES-I) 7-item questionnaire for the aging community in Iran.

Methods

The present psychometric work deals with outlining the validation and translation of FES-I (short version) among 9117 Persian-speaking elderly people with a mean age of 70.2±8.3 years (54.1% female and 45.9% male) in July 2021. Investigations were performed on confirmatory factor analysis, exploratory factor analysis, internal consistency, and construct validity along with test-retest reliability, receiver operating characteristic analysis, inter-rater, and convergent validity.

Results

72.4% of the subjects were living alone, 92.9% required support in activities of daily living, and 93.0% experienced falling in the past two years. A one-factor solution was assigned by exploratory factor analysis for FES-I. Thus, this model was proved by the confirmatory factor analysis with valid fit indices. Based on Cronbach's alpha, intra-cluster correlation coefficient, and McDonald's omega (≥ 0.80), internal consistency was confirmed. The exact cut-off value was represented by the receiver operating characteristic analysis for male/female and between with/without fear of falling among older samples with higher measures of specificity and sensitivity. Moreover, a significant effect of age, aging in place, loneliness, hospitalization rate, frailty, and sense of anxiety (effect size ≥ 0.80, p ≤ 0.05) on fear of falls was detected using analysis of variance.

Conclusions

The psychometric properties of the original scale were preserved by the Persian version of FES-I seven items as a self-reported measure of fear of falling. It could be assuredly a measure in both community and clinical settings. The possible uses and limitations of the Iranian FES-I were also discussed.

Effects of a 12-week Vivifrail exercise program on intrinsic capacity among frail cognitively impaired community-dwelling older adults: secondary analysis of a multicentre randomised clinical trial

INTRODUCTION

The World Health Organisation recently defined the construct of intrinsic capacity (IC), a function-based marker of older adult's health encompassing all mental and physical capacities of the individual. Multicomponent physical exercise (MCE) is a potential intervention capable to maintain/increase IC at older age; however, evidence is scarce on the effects of MCE on IC in cognitively impaired pre-frail/frail older adults.

METHODS

Secondary analyses of a randomised clinical trial. One hundred and eighty-eight older outpatients (age = 84.06 ± 4.77, 70.2% women) presenting with pre-frailty/frailty (according to Fried Criteria) and mild cognitive impairment (MCI)/mild dementia were recruited in the Geriatric clinics of three tertiary hospitals in Spain. Subjects were randomised to participate in the 12-week home-based individualised Vivifrail MCE or usual care. An IC index was created based on the z-score of the locomotion (Short Physical Performance Battery), cognitive (Montreal Cognitive Assessment), psychology (15-item Geriatric Depression Scale Yesavage) and vitality (handgrip strength) domains.

RESULTS

After the 3-month intervention, linear mixed models showed significant between-group differences in the evolution of the IC composite score (β=0.48; 95% confidence interval [CI] = 0.24, 0.74; P < 0.001), IC Locomotion (β = 0.42; 95% CI = 0.10, 0.74; P < 0.001), IC Cognition (β = 0.45; 95% CI = 0.03, 0.87; P < 0.05) and IC Vitality domains (β = 0.50; 95% CI = 0.25, 0.74 at 3-month) favouring the MCE group.

CONCLUSIONS

The 12-week Vivifrail multicomponent exercise program is an effective strategy to enhance IC, especially in terms of locomotion, cognition and vitality IC domains in community-dwelling older adults with pre-frailty/frailty and MCI/mild dementia, compared to usual care.
