Correlação entre tempo sentado e comprometimento motor de membros inferiores em pacientes pós-AVC: um estudo transversal / Correlation between sitting time and lower limb motor impairment in post-stroke patients: a cross-sectional study

INTRODUÇÃO: As deficiências físicas ocasionadas pelo Acidente Vascular Cerebral (AVC) podem estimular os pacientes a manterem um baixo condicionamento físico e a se tornarem cada vez mais sedentários. O comportamento sedentário tem efeitos prejudiciais à saúde, incluindo um maior risco de incidência de doenças cardiovasculares. OBJETIVO: Verificar se existe correlação entre o tempo sentado e o comprometimento motor de membros inferiores em pacientes pós-AVC. MÉTODOS: Trata-se de um estudo observacional, de caráter transversal, onde foram analisados pacientes com diagnóstico clínico de AVC na fase crônica, de ambos os sexos. O tempo sentado foi analisado por meio da seção 5 do Questionário Internacional de Atividade Física (IPAQ) e a função motora por meio da Escala de Fugl-Meyer - subseção de membros inferiores. Os participantes foram avaliados em uma única sessão, com duração média de 1 hora. RESULTADOS: A correlação pelo coeficiente ρ de Spearman entre a Escala Fugl-Meyer- subseção de membros inferiores (MMII) e IPAQ-tempo sentado durante a semana foi de r= -0,639 (p=0,008) e IPAQ-tempo sentado durante final de semana foi de r= -0,603 (p=0,013). Os pacientes passam 11,59 horas/dia durante a semana e 12,15 horas/dia durante o final de semana na posição sentada. CONCLUSÃO: Os resultados mostram uma relação negativa entre as variáveis estudadas, sugerindo que quanto maior o comprometimento motor dos MMII, maior será a média de tempo sentado do indivíduo após AVC.

INTRODUCTION: The physical deficiencies caused by stroke can encourage patients to maintain a low physical condition and become increasingly sedentary. Sedentary behavior has harmful health effects, including an increased risk of cardiovascular disease. OBJECTIVE: To verify whether there is a relationship between daily sitting time and lower limb motor impairment in post-stroke patients. METHODS: This is an observational, cross-sectional study, in patients with clinical diagnosis of stroke in the chronic phase, of both genders. Sitting time was analyzed using the 5th section of the International Physical Activity Questionnaire (IPAQ) and the motor function using the Fugl-Meyer Scale - lower limbs (LL) subsection. Participants were evaluated in a single session, with an average duration of 1 hour. RESULTS: The correlation by Spearman's ρ coefficient between the FuglMeyer Scale subsection for lower limbs and IPAQ weekdays sitting time was -0.639 (p=0.008) and IPAQ weekend days sitting time -0.603* (p= 0.013). Patients spend 11.59 hours/ day on weekdays and 12.15 hours/day on weekends in the sitting position. CONCLUSION: The results show a negative relationship between the variables studied, suggesting that the greater the lower limb motor impairment, the greater the average sitting time of the individual after the stroke.

Consequences of social distancing during the COVID-19 pandemic on the increase in perceived pain of students and professors from higher education institutions: A cross-sectional study.

BACKGROUND: Social distancing was implemented worldwide due to the coronavirus (COVID-19) pandemic. This impacted physical activity levels and increased the time spent in sedentary behaviors which may contributed to the emergence of increased musculoskeletal complaints. OBJECTIVE: To assess the consequences of social distancing for the increase in perceived pain of students and professors from higher education institutions. METHODS: One thousand two hundred and fifty-four participants responded to an online survey containing sociodemographic information and questions related to daily habits, physical activity profile, and musculoskeletal pain before and during the pandemic. Levels of concentration, nervousness, productivity, and visual fatigue were also assessed. The primary outcome was presence of perceived pain before and during the pandemic, dichotomized between those with and without increased pain during the pandemic. RESULTS: Perceived pain increased during the pandemic (p < 0.001) and was associated with females (p = 0.023; PR = 1.16; 95% CI = 1.02-1.32), income up to one minimum wage (p = 0.039; PR = 1.20; 95% CI = 1.01-1.42), no physical activity practice (p = 0.006; PR = 1.22; 95% CI = 1.06-1.40), long time in sedentary behavior (p = 0.013; PR = 3.07; 95% CI = 1.27-7.43), and electronic device usage for > 6 hours (p = 0.041; PR = 1.44; 95% CI = 1.02-2.06). Nervousness (p = 0.001) and visual fatigue (p = 0.001) increased, whereas concentration (p = 0.001) and productivity (p = 0.001) reduced during the pandemic. CONCLUSIONS: Reduced physical activity practice and increased time in sedentary behavior and electronic device usage during the pandemic were associated with increased musculoskeletal pain in students and professors from higher education institutions. Decreased concentration and productivity and increased nervousness and visual fatigue were also observed during the pandemic.
