Autor(es): Melo, Natália Gomes Abstract: Introduction: The Timed Up & Go (TUG) test assesses functional mobility and has gained relevance in Chronic Obstructive Pulmonary Disease (COPD), primarily affecting elderly individuals. In this population, the TUG has been suggested for fall risk screening and as a measure of physical performance related to nutritional assessment. It can also be used in different physical performance assessment scenarios, in addition to demonstrating consistent measurement properties. The original protocol requires individuals to walk at their usual speed, but over the years, another protocol at maximum speed has been suggested. Due to the relatively subtle difference in test execution, many researchers have used both variations in individuals with COPD, sometimes treating them as interchangeable, which can be problematic. Objective: To compare the time in the usual TUG with the time in the maximum TUG, and to verify if the time in the maximum TUG is able to predict the time in the usual TUG in elderly individuals with COPD. Methods: A cross-sectional study that included clinically stable individuals diagnosed with COPD, aged 60 years or older, and without conditions that could compromise or confound the results of the assessment. An initial assessment was performed to obtain sociodemographic (e.g., sex, age), anthropometric (e.g., weight, height), and clinical (pulmonary function, impact of dyspnea, health status) data. Functional mobility was assessed using two TUG protocols: TUG_usual and TUG_max (the test consists of asking the individual to walk a pre-established 3- meter path, starting and returning to a seated position, and timing the time required to complete it; in TUG_usual, the usual speed was requested, while in TUG_max, the maximum speed was requested). Results: One hundred and eighty elderly individuals with COPD were included, with a mean age of 72 (67-77) years, mostly female (56%), and a mean post-bronchodilator 1-second expiratory volume of 56 ± 19% of predicted. The median time in the usual TUG was 12.0 (10.49- 14.53) seconds, statistically greater than in the maximum TUG of 9.31 (7.91-11.11) seconds (p<0.0001), with a difference between the two tests of 2.74 (1.83-3.85) seconds. One hundred and nine (61%) individuals presented reduced functional mobility in the usual TUG and 91 (51%) in the maximum TUG. There was a discrepancy in classification between the two protocols in 36 individuals (20% of the sample). Both protocols showed a reasonable correlation with the age variable, in addition to showing a weak or no correlation with the mMRC variable (p<0.0001). A regression analysis indicated that the TUG_usual time can only be predicted for men, based on the TUG_max time and age using the following equation: TUG_usual time = -0.806 + (1.027 x TUG_max time) + (0.047 x age); R2 = 0.85, p<0.001. Conclusion: The TUG_usual time is statistically greater than the TUG_max time in elderly patients with COPD. Furthermore, approximately 20% of the sample differed in the classification of reduced functional mobility between the protocols, suggesting that the protocols are not interchangeable. However, for men, the TUG_usual time can be acceptably predicted from the TUG_max time and age.

Despite this, studies in this area do not explore whether social determinants of health (SDH) influence the protection or increase of disability, and patient-reported outcome measures (PROMs) are unclear in reflecting functioning. This dissertation aims to investigate whether social determinants of health (SDH) influence disability in older adults twelve months after the episode, as well as to identify whether PROMs cover LD-related disability/functioning in the context of aging. In product 1, a systematic review was conducted of disability in older adults with chronic DL, assessing whether the PROMs used to obtain these results are consistent with the ICF structure and the related Geriatric Core Set. A search was conducted in the main health databases, such as PubMed, Embase, Lilacs, and the Virtual Health Library (VHL). Of the 24 studies included, eight PROMs were identified to assess disability in older adults with DL. The main and additional concepts of the PROMs were linked to identify the corresponding International Classification of Functioning, Disability, and Health (ICF) codes, which were then compared with the Geriatric Core Set codes. This product showed that the PROMs that assess disability in older adults with DL do not reflect functioning in the aging scenario. We concluded that further studies are needed to create appropriate PROMs to assess disability in older adults with DL. In product 2, a longitudinal study was conducted using data from the “Back Complaints in the Elders” database in Brazil, BACE-Brasil, to investigate the association between DSS and disability in older adults with acute DL twelve months after the onset of the episode. The independent variables analyzed were DSS and the dependent variable was the Roland-Morris Disability Questionnaire (RMDQ), which assesses disability resulting from LDS at baseline and twelve months after the episode. We revealed, through multivariate logistic regression, these higher income and education levels, as well as darker skin color, were associated with lower disability rates.These findings increased the chance of disability reduction by 1.26, 1.04, 2.1, and 2.4 times, respectively. Health professionals should take these socioeconomic variables into account to better understand the process of recovery from disability in aging. Finally, researchers need to develop PROMs that reflect functioning to cover aspects of aging in disability resulting from DL in older adults, and clinicians must understand that variables such as low income, low education, and skin color influence disability recovery in older adults with DL.

Therefore, this study aimed to develop and validate the content of an observational instrument to assess engagement among elementary school children, both with and without disabilities. The instrument was constructed in four stages: (i) development of the first version, (ii) pilot study, (iii) relevance analysis, and (iv) restructuring. Content validation, data analysis, and verification of reliability and trustworthiness were conducted by a panel of five expert judges. A pilot study was then carried out with 15 students, of both sexes, from two private schools in Fortaleza, Ceará. Results indicated that the criterion of Language Clarity generated the greatest divergence among expert judges, particularly within the behavioral dimension of engagement. In terms of student participation, 10 students demonstrated adequate active engagement, while 5 students scored between 2.2 and 2.4, suggesting the need for improvements. In conclusion, the instrument proved to be effective in assessing engagement in PE contexts and may support health and education professionals in monitoring children across diverse social environments, contributing to a better understanding of individual social participation, an essential component of child development.

In Brazil, the lack of validated questionnaires for early screening of this condition hinders the identification of its initial stages, potentially resulting in delayed diagnoses, invasive treatments, and high costs to the healthcare system. To address this gap, this study aimed to translate, cross-culturally adapt, and validate the Brazilian version of the Oslo Sports Trauma Research Center – Patella (OSTRC-P) questionnaire, originally developed to assess functional impairments associated with patellar tendinopathy. The cross-cultural adaptation process followed international COSMIN guidelines, involving independent translation by two bilingual professionals, synthesis of the translated versions, back-translation into English, and review by a committee of experts in sports and orthopedic physiotherapy. After semantic and cultural adjustments—such as replacing specific terms (e.g., "experienced pain" with "felt pain")—the pre-final version was pre-tested with participants from the target population to assess item clarity.For psychometric validation, 105 physically active individuals were recruited and divided into three groups: Control (asymptomatic), Risk (engaged in high-impact sports without symptoms), and Tendinopathy (clinically diagnosed based on pain upon palpation of the patellar tendon—intensity ≥3 on the Numeric Pain Rating Scale—and a VISA-P score <80). Participants completed the OSTRC-P-Br, the Victorian Institute of Sport Assessment–Patella (VISA-P), and the Lower Extremity Functional Scale (LEFS) at two time points, 15 minutes apart. The Delphi committee reached consensus after three review rounds, with over 90% agreement on the adapted items. In the pre-test, 98% of participants reported clear understanding of the items. During validation, the OSTRC-P-Br demonstrated high internal consistency (Cronbach’s alpha = 0.88; 95% CI 0.84–0.91), excellent inter-rater reliability (ICC = 0.955; 95% CI 0.92–0.98), and significant inverse correlations with the VISA-P (rho = –0.825; p < 0.001) and LEFS (rho = –0.659; p < 0.001), supporting its construct validity.In diagnostic analysis, the OSTRC-P-Br demonstrated high accuracy, with a sensitivity of 90% and a specificity of 91.4%, showing excellent discriminatory power for detecting patellar tendinopathy and ruling out false positives. A floor effect was observed in the control group, which had fixed scores (0.0 ± 0.0), while no ceiling effect was found in the other groups. The tendinopathy group showed significantly higher mean scores (38.0 ± 22.0) compared to the Control (0.0 ± 0.0) and Risk (0.0 ± 9.5) groups. These findings support the conclusion that the OSTRC-P-Br is a valid, reliable, and culturally adapted instrument for early screening of dysfunctions related to patellar tendinopathy in the Brazilian context. Its use in clinical practice may facilitate early detection and timely intervention, helping prevent chronic complications. Additionally, the questionnaire contributes to the standardization of epidemiological studies and the generation of internationally comparable data, thereby strengthening prevention and management strategies for patellar tendinopathy in Brazil.
