RESUMEN La artralgia crónica poschikunguña (ACPC) puede tener como efecto repercusiones musculoesqueléticas y pérdida funcional. En este sentido, el objetivo de este estudio fue evaluar la discapacidad física y los síntomas de miembros superiores de mujeres con ACPC durante las actividades diarias, laborales y de ocio en comparación con controles sanos (CS). Por ello, se realizó un estudio transversal con 52 mujeres. Las participantes se dividieron en los grupos ACPC (37) y CS (15). La fuerza de agarre, el rango de movimiento (ROM), el nivel de dolor (escala numérica de dolor), la discapacidad física y los síntomas se evaluaron mediante el Disabilities of the Arm, Shoulder and Hand Questionnaire (Dash). Las diferencias entre los grupos se evaluaron con la aplicación de la prueba t de Student y las correlaciones de Pearson. Se utilizó la prueba de chi-cuadrado para las variables categóricas y se estableció como nivel de significación α=0,05. Se encontró que la duración de la ACPC fue de 19,5±13,1 meses. No hubo diferencia entre los grupos para la fuerza máxima (ACPC: 23,6±7,4kgf; CS: 24,5±6,2kgf; p=0,676). Los resultados mostraron una diferencia significativa entre los grupos respecto al ROM (ACPC: 63,5±17,3o; CS: 77,2±9,6o), el nivel de dolor en la mano (ACPC: 5,8±2,2; CS: 0,4±1,5) y los niveles funcionales de miembros superiores (ACPC: 44,5±17,4; CS: 16,2±20,5). Las participantes informaron una extrema dificultad o incapacidad para realizar tareas como abrir un frasco (78,4%), poner objetos en un lugar más alto (48,7%), realizar actividades domésticas pesadas (56,8%) y actividades de jardinería (51,4%). Se concluyó que la función física de los miembros superiores durante las actividades diarias, laborales y de ocio constituye el mayor compromiso a largo plazo. (ACPC funcional sentido diarias CS. .

ABSTRACT Post-Chikungunya chronic arthralgia (PCCA) may lead to musculoskeletal repercussions and functional loss. The objective was to assess the upper limb physical disability and symptoms during daily, work, and leisure activities of women presenting PCCA compared to healthy controls (HC). This was a cross-sectional study conducted with 52 women. The participants were divided into PCCA (37) and HC (15) groups. Handgrip strength, range of motion, level of pain (numerical rating scale), and participants’ physical disability and symptoms (Disabilities of the Arm, Shoulder, and Hand Questionnaire - DASH) were evaluated. Differences between groups were evaluated using the Students t-test and Pearson’s correlations. The chi-square test was applied for categorical variables. The significance was set at α=0.05. The disease duration was 19.5±13.1 months. We found no differences between groups for peak force (PCAA:23.6±7.4kgf; HC: 24.5±6.2kgf; p=0.676). The results showed a significant difference between groups regarding range of motion (PCCA: 63.5±17.3o; HC: 77.2±9.6o), level of hand pain (PCCA: 5.8±2.2; HC: 0.4±1.5), and upper limbs functional levels (PCCA: 44.5±17.4; HC: 16.2±20.5). Participants related severe difficulty or inability to perform tasks such as opening a jar (78.4%), placing objects above head height (48.7%), doing heavy household chores (56.8%), and gardening (51.4%). Impairment in the upper limb physical function in daily, work, and leisure activities shows the higher prevalence in the long-term. PostChikungunya Post Chikungunya (PCCA loss daily work HC. .

RESUMO A artralgia crônica pós-Chikungunya (ACPC) pode gerar repercussões musculoesqueléticas e perda funcional. Nesse sentido, o objetivo deste estudo foi avaliar a incapacidade física e os sintomas de membros superiores de mulheres com ACPC durante atividades diárias, laborais e de lazer comparadas aos controles saudáveis (CS). Para tanto, realizou-se um estudo transversal conduzido com 52 mulheres. As participantes foram divididas entre os grupos com ACPC (37) e CS (15). Foram avaliados força de preensão, amplitude de movimento (ADM), nível de dor (escala numérica de dor) e incapacidade física e sintomas por meio do Disabilities of the Arm, Shoulder and Hand Questionnaire (Dash). Diferenças entre os grupos foram avaliadas pelo teste t de Student e correlações de Pearson. O teste qui-quadrado foi utilizado para variáveis categóricas e α=0,05 foi estabelecido como nível de significância. Verificou-se que a duração da ACPC foi de 19,5±13,1 meses. Não houve diferença entre os grupos para a força pico (ACPC: 23,6±7,4kgf; CS: 24,5±6,2kgf; p=0,676). Os resultados demonstraram diferença significativa entre os grupos em termos de ADM (ACPC: 63,5±17,3o; CS: 77,2±9,6o), nível de dor nas mãos (ACPC: 5,8±2,2; CS: 0,4±1,5) e níveis funcionais dos membros superiores (ACPC: 44,5±17,4; CS: 16,2±20,5). As participantes relataram extrema dificuldade ou incapacidade para realizar tarefas como abrir um pote (78,4%), colocar objetos em um local acima da cabeça (48,7%), realizar atividades domésticas pesadas (56,8%) e atividades de jardinagem (51,4%). Conclui-se que a função física dos membros superiores durante as atividades diárias, laborais e de lazer constitui o maior comprometimento apresentado a longo prazo. pósChikungunya pós Chikungunya (ACPC funcional sentido diárias CS. .

Abstract Aim: This study aimed to compare the performance, metabolic, hemodynamic, and perceived exertion during the 6-minute step test (6MST) conducted with different step heights in healthy subjects and also to compare the performance between different age groups for each step height. The association between age, body mass index, level of physical activity, and lower limb measurements with performance were also evaluated. Methods: This is a cross-sectional study. Anthropometric measures, physical performance, and cardiovascular stress were evaluated during a self-paced 6MST with different step heights in healthy subjects in the age group of 18-59. All the participants underwent three-step tests (15 cm, 20 cm, and 30 cm) on the same day, in a randomized order. Results: Forty participants (20 men and 20 women) performed the tests. The performance in the test for the highest step was significantly lower compared to the step with the lowest height (152 ± 24 vs. 173 ± 27 and 184 ± 33; p < 0,05). The estimated peak oxygen consumption (VO2peak) increased by ∼2.5 mL.kg−1·min−1 with the increase in step height. Hemodynamic variables, such as percent of maximum heart rate (%HRmáx), and systolic blood pressure increased as the step height increased. There was a fair correlation between performance and the level of physical activity in the test with a step height of 15 cm and 20 cm. Conclusion: A higher step height caused greater cardiovascular stress, without exceeding the submaximal levels of the test, indicating that the 6MST can be used as an accurate instrument for evaluating aerobic capacity in healthy individuals.

Abstract Aims: To determine the incidence of injuries in exclusive treadmill runners and the main associated factors in 24 weeks. Methods: The incidence of injuries was investigated every two weeks by an electronic form. To analyze the associated factors, muscle force output, range of motion, and flexibility were investigated. To perform a descriptive analysis (baseline) and injury predictive factors (regression), we divided runners into two groups, injured and uninjured. Comparisons between groups were assessed evaluated by Student's t-test, Mann-Whitney, or Chi-square test. The relationship between associated factors and incidence of injuries was estimated by Logistic regression analysis. The model's accuracy was assessed by the receiver-operating characteristic curve (ROC). Thirty-seven runners completed the study. Results: The incidence of injuries was 6.8 per 1,000 hours of exposure. Among the associated factors, we highlight that runners with higher hip flexor force output were 4 times more likely not to injure (OR 4.0; CI 95% 1.03 -16.23) and lower knee extensor force output was related to a greater chance of injury (OR .24; 95% CI .65 - .93). The area under the ROC curve was 0.84. Conclusion: The incidence of injuries in treadmill runners was high. The factors associated with the injuries were the output of the flexor strength of the hip and the extensor force of the knee.
