User and family satisfaction with nursing homes: a systematic review.

BACKGROUND: Implementation of person-directed care planning is a challenge for nursing home services. User satisfaction is indispensable to implement it. OBJECTIVE: The aim of this study was to address user and family satisfaction with nursing homes and the scales used and to identify the determinants of satisfaction with this service. METHODS: A systematic review was conducted, and the Cochrane Library, PubMed, Scopus, Web of Science and CINAHL databases were searched between December 2019 and April 2020. Studies involving assessment of user or family satisfaction with nursing homes and users ≥65 years old or their families were included in this review. The methodological quality of the included studies was assessed by the Joanna Briggs Institute reviewer's manual. RESULTS: Eight articles were included based on the eligibility criteria, from a total of 2378 records found in the electronic search. All studies presented a cross-sectional design, and the total sample of this review was 57 214 older people. Most of the studies included showed positive overall satisfaction with nursing homes. There was no consensus about the best scale to assess satisfaction because of the huge variety of tools among studies. The most common determinants of satisfaction among studies were quality of life (mental and physical components), anxiety and social and health factors. CONCLUSION: The findings of our review may contribute to a better view of satisfaction with nursing homes experienced by users and families and to an improvement of care in these institutions.

Complexity of Knee Extensor Torque: Effect of Aging and Contraction Intensity.

ABSTRACT: Fiogbé, E, Vassimon-Barroso, V, Catai, AM, de Melo, RC, Quitério, RJ, Porta, A, and Takahashi, ACdM. Complexity of knee extensor torque: effect of aging and contraction intensity. J Strength Cond Res 35(4): 1050-1057, 2021-Assessing the knee extensors' torque complexity in older adults is relevant because these muscles are among the most involved in functional daily activities. This study aimed to investigate the effects of aging and isometric contraction intensity on knee extensor torque complexity. Eight young (24 ± 2.8 years) and 13 old adults (63 ± 2.8 years) performed 3 maximal (maximum voluntary contraction [MVC], duration = 10 seconds) and submaximal isometric contractions (SICs, targeted at 15, 30, and 40% of MVC, respectively) of knee extensors. Torque signals were sampled continuously, and the metrics of variability and complexity were calculated basing on the SIC torque data. The coefficient of variation (CV) was used to quantify the torque variability. The torque complexity was determined by calculating the corrected approximate entropy (CApEn) and sample entropy (SampEn) and its normalized versions (NCApEn and NSampEn). Young subjects produced greater isometric torque than older adults, and the CV was similar between both groups except at the highest force level (40% MVC) where young subjects' value was higher. The major novel finding of this investigation was that although the knee extensor torque complexity is reduced in older adults, its relationship with contraction intensity is similar to young subjects. This means that despite the age-related decrease of the interactions between the components of the neuromuscular system, the organization of force control remains preserved in older adults, at least up to just below the force midrange.

Effect of complementary therapies on functional capacity and quality of life among prefrail and frail older adults: A systematic review of randomized controlled trials.

OBJECTIVE: Investigate the effects of complementary therapies on functional capacity and quality of life among prefrail and frail older adults. MATERIALS AND METHOD: An electronic search was performed in the PubMed, EMBASE, Web of Science, Cochrane Library, LILACS and PEDro databases for relevant articles published up to September 2019. Only randomized controlled trials with interventions involving complementary therapies for prefrail and frail older adults were included. This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Cochrane recommendations. The methodological quality of the selected studies was appraised using the PEDro scale and the evidence was synthesized using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) scale. RESULTS: Fifteen studies met the inclusion criteria and were selected for the present review. Six different complementary therapies were identified and the main findings were related to Tai Chi. A very low to moderate level of evidence was found regarding the effectiveness of Tai Chi in terms a functional capacity (balance, mobility, gait speed, functional reach and lower limb muscle strength) and a low level of evidence was found regarding its effect on quality of life. To the other complementary therapies it was not possible to synthetize evidence level. CONCLUSION: Tai chi may be used as an important resource to improve functional capacity and quality of life among prefrail and frail older adults.

Accuracy of mobility tests for screening the risk of falls in patients with mild cognitive impairment and alzheimer's disease / Acurácia de testes de mobilidade para o rastreio do risco de quedas no comprometimento cognitivo leve e doença de Alzheimer / Exactitud de las pruebas de movilidad para detectar riesgo de caídas en el deterioro cognitivo leve y en la enfermedad de Alzheimer

ABSTRACT Identifying gait and balance disorders in the earlier stages of Alzheimer's disease (AD) and Mild Cognitive Impairment (MCI) could reduce or prevent falls in older adults. This cross-sectional study aimed to determine which mobility tests best discriminate the risk of falls in MCI and mild AD. Functional mobility was assessed by the timed up and go test (TUG) and 10-meter walk test (10MWT). A calendar of falls was produced, with follow-up via telephone calls during 6 months. For the MCI Group (n=38), time spent on the 10MWT was the best variable for discriminating fallers, with a cut-off point of 10.69 seconds associated with the highest accuracy (76.3%). In the AD Group (n=37), 10MWT cadence was the best variable for discriminating fallers, with a cut-off point of 101.39 steps per minute associated with an accuracy of 81.1%. As a conclusion, 10MWT time and cadence were the most accurate variables for screening the risk of falls in MCI and mild AD, respectively. The 10MWT is a functional, simple and easy test and it should be widely used in clinical practice.

Pre-Frail Multicomponent Training Intervention project for complexity of biological signals, functional capacity and cognition improvement in pre-frail older adults: A blinded randomized controlled study protocol.

AIM: Frailty syndrome is related to decreased physiological complexity, functional capacity and cognition. Physical exercise has been suggested to slow down and reverse this syndrome. However, evidence of its effectiveness is not as straightforward as conventionally admitted, as there is a lack of trials with rigorous methodology. The purpose of this study was to describe the Pre-Frail Multicomponent Training Intervention protocol. METHODS: Cardiovascular, motor control and neuromuscular systems of pre-frail older adults will be assessed by measuring the complexity of the output of these systems. Functional capacity and cognition will be assessed by specific tools. A 16-week training protocol will be carried out on three alternate days, with 60-min sessions, and combining aerobic, muscle strength, flexibility and balance exercises. The objective of this intervention is to improve the cardiovascular, motor control and neuromuscular systems, as well as functional capacity and cognition of pre-frail older adults. The assessment of these systems will be carried out using gold standard devices. RESULTS: The results of the present study might allow clinical and functional support for the evaluation of the variables analyzed. CONCLUSION: This protocol is easily reproducible and requires low-cost materials, thus the Pre-Frail Multicomponent Training Intervention could be a therapeutic strategy for pre-frail older adults.

Linear and nonlinear analysis of postural control in frailty syndrome.

BACKGROUND: Adaptive postural control can be impaired in the presence of frailty syndrome, given that this condition causes homeostatic dysregulation in physiological systems. OBJECTIVES: To compare the center of pressure (CoP) displacements of non-frail, pre-frail, and frail elderly subjects in the standing position before and after postural transition of sitting and rising from a chair, using linear and nonlinear methods. METHODS: Forty-two elderly subjects were divided into 3 groups: non-frail (n=15), pre-frail (n=15), and frail (n=12). The CoP displacements in the anteroposterior (AP) and mediolateral (ML) direction in the orthostatic position, 30s before and after sitting down and rising from a chair, were evaluated by means of linear measurements (root mean square (RMS), amplitude, and total average speed) and nonlinear measurements (corrected approximate entropy - CApEn), sample entropy (SampEn), and complexity index (CI) and its normalized versions. RESULTS: After sitting and rising, there was an increase in RMS in the ML direction in all groups and in the AP direction in the non-frail and frail groups. The frail group showed no reduction in entropy values in either direction, and the pre-frail group showed no reduction in the ML direction. CONCLUSIONS: The results of this study indicate that, in the presence of frailty syndrome, the organization of CoP displacements does not show less regularity after sitting and rising from a chair, reflecting a possible impairment of the integration of the systems involved in postural control.

Exercise training in older adults, what effects on muscle oxygenation? A systematic review.

AIM: To determine the effects of different modality of exercise training programs on muscle oxygenation in older adults. METHODS: Relevant articles were searched in PubMed, Web of Science, Science Direct and Scopus, using the keywords: "Aged" AND "Muscle oxygenation" AND (Exercise OR "Exercise therapy" OR "Exercise Movement Techniques" OR Hydrotherapy), without limitation concerning the publication date. To be included in the full analysis, the study had to be a randomized controlled trial in which older adults participants (mean age: 65 years at least) were submitted to an exercise-training program and muscle oxygenation assessment. RESULTS: The searches resulted in 1238 articles from which 7 met all the inclusion criteria. The trials involved 370 older adults (68.7±1.7years), healthy and with peripheral arterial disease. Studies included resistance and endurance exercises as well as walking sessions. Training sessions were 2-6 time per week, lasted 3-24 months and with different training intensity throughout studies. After a long-term resistance training, healthy older adults showed enhanced muscle oxygen extraction capacity, regulation of vessels and vascular endothelium function; endurance training is reported to improve microvascular blood flow and matching of oxygen delivery to oxygen utilization, muscle oxidative capacity and muscle saturation, and walking sessions results in better muscle oxygen availability and muscle oxygen extraction capacity in older adults with peripheral arterial disease. CONCLUSIONS: This review supports the fact that depending on the clinical status of the participants and the modality, exercise training improves different aspects of the muscle oxygenation in older adults.

Effects of the Addition of a Dual Task to a Supervised Physical Exercise Program on Older Adults' Cognitive Performance.

The purpose of this study was to investigate the effects of the addition of a dual task to multicomponent training on cognition of active older adults. Eighty physically active older adults were divided into an intervention group (IG) and a control group (CG). Both groups performed multicomponent training over 12 weeks. The IG simultaneously performed exercises and cognitive tasks. The Mini-Mental State Examination, the Montreal Cognitive Assessment, and the Clock Drawing Test were used for cognitive assessments. The Timed Up and Go Test associated with a cognitive task was used for dual-task assessment. Significant interactions were not observed between groups in terms of the cognitive variables or the dual-task performance. An interaction was observed only for Timed Up and Go Test performance, which was better in the CG than in the IG. Active older adults showed no improvement in cognition following the addition of the dual task to the multicomponent training.
