Item Acesso aberto (Open Access) Análise Psicométrica da Versão Brasileira da Pittsburgh Fatigability Scale (PFS-Brasil)(Universidade Federal do Pará, 2024-04-24) SANTOS, Mayara do Socorro Brito dos; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211XIntroduction: Instruments with appropriate psychometric properties are essential for ensuring the quality of assessments and reassessments in clinical practice, guiding decision-making regarding rehabilitation procedures. The Pittsburgh Fatigability Scale, originally published in English, is the only validated scale for measuring perceived fatigability in older adults. Considering the importance of this tool, it is necessary to validate its translated version into Portuguese and adapt it to the specificities of the Brazilian context. Objective: To validate the Pittsburgh Fatigability Scale Brazilian Portuguese version (PFS-Brasil) by evaluating its validity in relation to measures of physical activity, physical performance, and cognitive performance. Methodology: The scale and physical and cognitive performance tests were used to assess 121 healthy older adults residing in the community. We conducted statistical analyses of the physical and mental subscales of the PFS-Brasil, utilizing the intraclass correlation coefficient (ICC) for reliability analysis, Cronbach's alpha for internal consistency evaluation, and Spearman's correlation for convergent validity. Furthermore, we examined agreement analysis and floor and ceiling effects. The Statistical Package for Social Sciences 25.0 was used for data analysis. Results: The analyses indicated that the physical and mental subscales exhibit satisfactory test-retest reliability, with ICC values for the physical subscale (0.84; 95% CI: 0.80-0.88) and the mental subscale (0.83; 95% CI: 0.78-0.87), in addition to high internal consistency (α = 0.84 and 0.82, respectively). These values are indicative of good inter-rater reliability, revealing a low probability of random and systematic error. Bland-Altman plots demonstrated good agreement for both subscales of the PFS-Brasil. For convergent validity, the higher physical score showed a moderate association, and the higher mental score showed a weak association with lower physical performance (6-minute walk tests and the Short Physical Performance Battery (SPPB) and lower levels of physical activity (International Physical Activity Questionnaire – IPAQ). Regarding cognitive performance, there was a weak association between the higher mental score and the average accuracy on the flanker test. No ceiling effects were observed in both subscales; however, the mental subscale exhibited a floor effect (n = 24%). Conclusion: This study demonstrated that the Brazilian version of the Pittsburgh Fatigability Scale is a valid, consistent, and reliable instrument for assessing perceived fatigability in older adults.Item Acesso aberto (Open Access) Estratificação de risco de fragilidade, incapacidade e avaliação de distúrbios de sono na pessoa idosa residente da comunidade: estudo transversal(Universidade Federal do Pará, 2023-10-30) RIBEIRO, Breno Caldas; CARNEIRO, Saul Rassy; http://lattes.cnpq.br/9162153771863939; https://orcid.org/0000-0002-6825-0239; NEVES, Laura Maria Tomazi; http://lattes.cnpq.br/4235603520707156; https://orcid.org/0000-0002-3115-2571Background: Fragility is considered a state of vulnerability to health stressors, rendering elderly individuals susceptible to disability, hospitalization, and mortality. Recent studies have indicated an increase in the prevalence of frailty risk among older adults with sleep disturbances. Given that frailty is a dynamic condition with the potential for reversal, it is imperative to screen for possible modifiable factors to prevent, mitigate, or interrupt the frailty process. Consequently, there is a need for the stratification of frailty and an investigation into the potential associations between sleep quality, excessive daytime sleepiness, and the risk of sleep disorders in older adults. Objective: To stratify the risk of frailty and disability and investigate potential associations with sleep quality, excessive daytime sleepiness, and the risk of Obstructive Sleep Apnea (OSA) in community-dwelling older adults. Methods: This study employs a quantitative cross-sectional design, adhering to the recommendations of The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). The research involves the stratification of frailty and disability using the Frail Non-disable Questionnaire (FiND) and the FRAIL Scale, along with the evaluation of excessive daytime sleepiness, sleep quality, and the risk of OSA through the Epworth Sleepiness Scale (ESE), Pittsburgh Sleep Quality Index (PSQI), and STOP-BANG questionnaire, respectively. Data normality was assessed using the Kolmogorov-Smirnov test. For binomial categorical comparisons, the Binomial Test was employed, while the Proportions Test was utilized for multiple comparisons. Correlation analysis was conducted using Spearman's Correlation Test. Results: A total of 109 older adults (61% females, p = 0.02) were evaluated, with a median age of 68, from the capital city (86%), self-identified as mixed race (68%), and in a state of preobesity (36%). According to FiND, 26% of participants were deemed frail and 32% were considered incapable. In contrast, according to the FRAIL Scale, 33% were pre-frail and 25% were frail. In addition, most patients had poor sleep quality (80%, p = 0.010), moderate risk of obstructive sleep apnea (49%, p < 0.010) and absence of excessive daytime sleepiness (62%, p < 0.010). There was a weak relationship between frailty and disability with poor sleep quality (rho = 0.39; p < 0.001) and risk of obstructive sleep apnea (rho = 0.26; p = 0.000). No relationship was observed between frailty and disability and excessive daytime sleepiness (rho = 0.04; p = 0.660). A weak relationship with sleep quality (rho = 0.33; p < 0.001) and the risk of obstructive sleep apnea (rho = 0.27; p = 0.001) was also observed in the analysis of correlation with frailty, but no relationship was found with excessive daytime sleepiness (rho = 0.05; p = 0.590). Conclusion: This study showed a weak relationship between the risk of frailty 8 and disability with sleep quality and the risk of obstructive apnea, but no relationship was observed with excessive daytime sleepiness.Item Acesso aberto (Open Access) A intervenção em dupla-tarefa protege do declínio associado à idade nas atividades em dupla-tarefa(Universidade Federal do Pará, 2023-04-18) PONTES, Helen Tatiane Santos; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211XIntroduction: Older adult’s functionality is related to the ability to divide attention into daily life multitasking activities. The ability to coordinate attention in motor and cognitive activities performed simultaneously decreases with aging, compromising functional ability, and therefore older adults' participation and healthy aging. Objectives: The main objective of the present study is to evaluate the effects of a multimodal physical exercise intervention protocol, at moderate intensity, simultaneously with cognitive stimulation (dual-task) on the dual task cost in healthy community-dwelling older adults. Methods: 70 older adults, with no cognitive disfunction participated in the study. Participants were grouped into a Dual Task Exercise group (DTEx, n=40) who performed the intervention protocol of 24 sessions, twice a week, for 75 minutes, and a control group (CG, n=30) who received information on health education and did not perform physical exercises. Two-way mixed ANOVA was used for dual-task cost analysis and Bonferroni tests were used as post-hoc for within-group and between-group comparisons. The project was registered in the Brazilian Registry of Clinical Trials (UTN code: U1111-1233 6349) and approved by the Research Ethics Committee of the Institute of Health Sciences of the Federal University of Pará (CAAE no. 03427318.3.0000.0018). Results: There was Group x Time interaction (F (1.68) = 7.207 p ≤ 0.009, η2 p = 0.096) observed for the performance of the motor component of the dual task cost. The DTEx group showed maintenance of the gait speed as the motor component of the dual task cost (Assessment = -11.4% ± 3.0; Reassessment = 10.2% ± -2.6, p = 0.665) while the CG showed an increased cost of approximately 49.76% (Assessment: -10.4% ± 3.4; Reassessment: -20.9% ± 3.0 p ≤ 0.002). Significant differences were found on the performance of the motor component of the cost of the dual task between the groups in the post-intervention condition (GC Reassessment: -20.9 ± 3.0. Reassessment DTEx = -10.2% ± -2.6, p ≤ 0.011). No main effects were observed in the assessment of the cost of the cognitive component. Conclusions: The results suggest that moderate-intensity multimodal physical exercise associated with dual-task cognitive stimulation attenuated the decline in the dual-task cost in the older adults. The cost of dual task is an important clinical measure to assess the functional and cognitive ability to perform tasks of daily living in aging.Item Acesso aberto (Open Access) Respostas do pilates em dupla tarefa sobre parâmetros cognitivos e funcionais de mulheres pós-menopáusicas(Universidade Federal do Pará, 2021-12-17) SILVA, Daniel José Fontel da; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211XAging may cause morphological and functional changes that may lead to decrease on physical functional and cognitive performance throughout aging, particularly on post-menopausal women. The performance in situations of divided attention (dual-task) may be reduced with advancing age, favoring the risk of falls and limiting functionality. The Pilates method is a form of physical exercise that combines strength and balance training and promotes improvement on these physical fitness variables in older adults. Considering the available evidence that dual- task training may promote additional benefits to the exercises performed isolated, including the prevention and/or improvement of cognitive decline associated with age, this study aimed to propose and evaluate the effects of a dual-task protocol composed of mat Pilates and Cognitive stimulation (PILATES-COG) on healthy, community-dwelling post-menopausal older women, compared to a group that received health education related materials. This is a non-randomized controlled trial, 47 women participated in this study (PILATES-COG =22; Control= 22), with amenorrhea for at least 12 months, and performance on the Mini-Mental State Examination compatible with normality, adjusted for schooling. Twenty-four sessions of solo Pilates were held, 2x week, during approximately 50 minutes, in classes, involving mat exercises and simultaneous cognitive tasks. Memory assessment (Word List, Delayed Recall and Recognition of the CERAD battery - Consortium to Establish a Registry for Alzheimer's Disease), language (Semantic and Phonological Verbal Fluency), balance (mini-BESTest), lower-limb muscle strength (Chair Sit-to-Stand Test), functional mobility (Timed Up and Go test – TUG; TUG with dual-task – TUG DT) and Dual-Task Cost (DT Cost). Two-way mixed ANOVA was used for data analysis, and Bonferroni was used as post-hoc to perform intra- and inter-group comparisons. Effect sizes were described with partial eta squared. Our results show that the main effects of Time were found for both Semantic Fluency (p = 0.002) and Phonological Fluency (p = 0.002), Immediate memory (p < 0.001) and Evocation Memory (p < 0.001), lower- limb muscle strength (p<0.001), balance (p<0.001) dual-task gait speed (p=0.023) and DT cost (p=0.012). Main effects of Group were found for lower-limb muscle strength, balance, TUG, TUG DT, speed in one and dual-task (p<0.001). There was interaction between Time and Group for language (p=0.017) as well as Balance and Lower-limb muscle strength (p=0.015; p=0.008). In the intragroup comparison, the participants on the Pilates group showed improvement after the intervention for the assessment of Language (p<0.001), Memory (p=0.001), Lower-limb muscle strength (p<0.001), balance (p<0.001) and DT Cost (p<0.05). The dual-task intervention, composed of mat Pilates exercises and cognitive stimulation, improved language, memory, lower limb muscle endurance and balance in postmenopausal women. We suggest this protocol may be a viable and effective strategy to reduce age-related cognitive decline and improve physical functional performance in healthy postmenopausal women.Item Acesso aberto (Open Access) Tradução e adaptação transcultural da Pittsburgh Fatigability Scale para o português brasileiro(Universidade Federal do Pará, 2023-04-28) SANTANA, Larissa Lopes; TORRES, Natáli Valim Oliver Bento; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211XBackground: Fatigue is a symptom associated with the weakening or depletion of an individual's physical and/or mental resources. The term fatigability comprises the subjective perception of fatigue in face of activities of specific intensity and duration. The Pittsburg Fatigability Scale (PFS), originally published in English, is the only validated scale to measure perceived fatigability in older adults. Considering the importance of specific assessment in the aging population for the prevention of conditions and for the rehabilitation, it is necessary to translate and adapt it cross-culturally to the specificities of the Brazilian context. Objective: To translate and cross-culturally adapt the Pittsburgh Fatigability Scale into Brazilian Portuguese to assess fatigability in the Brazilian older adults population. Methodology: We carried out the translation and cross-cultural adaptation to generate the PFS version in Brazilian Portuguese (PFS-Brasil), following the steps: translation from the source language (English), comparison and synthesis of translated versions, blind back-translation, comparison of back-translations and assessment of instrument clarity by the expert committee. People aged 60 years and overwho met the inclusion and exclusion criteria were invited to participate voluntarily in the study after approval by the Research Ethics Committee of the Institute of Health Sciences of the Federal University of Pará (nº 56210622.0.0000.0018) and signature of the TCLE. Each participant provided demographic data, responded to the PFS-Brasil and reported their understanding, difficulty in responding and suggestions about each item on the scale. All assessments were performed in environments with noise, temperature and lighting control to ensure privacy and comfort conditions for the proper performance of the tests. The R software was used to analyze the evidence of construct validity and instrument precision based on Confirmatory Factor Analysis (CFA), Cronbach's (α), McDonald's (ω) and composite reliability. Results: The Brazilian version of the PFS (PFS-Brasil) was developed. The pilot test referring to the last phase of the cross-cultural adaptation was carried out with 103 participants, predominantly female (81.5%), married (41.7%), brown (60.1%), who did not have COVID-19 (50.4%) and who perform some type of physical activity (64%). Confirmatory factor analyzes carried out point to the adequacy of bifactorial models for both subscales (x²: 48.53 for the physical subscale and x²: 35.05 for the mental subscale), with excellent and satisfactory internal consistency in factors 1 (⍺: 0, 9) and 2 (⍺: 0.76) of the Mental Fatigue subscale, respectively. As for the Physical Fatigue subscale, it presented very good results for factor 1 (⍺: 0.8) and satisfactory for factor 2 (⍺: 0.6). Conclusion: The present study demonstrated that the Brazilian version of the Pittsburgh Fatigability Scale has adequate construct validity for assessing perceived fatigability in older adults, both in its physical and mental subscales.
