ResumoIntrodução: Hipertensão é condição clínica de alta prevalência e principal fator de risco para doenças cardiovasculares e cerebrovasculares. Uma das repercussões hemodinâmicas é a diminuição do aporte energético da musculatura pelo comprometimento da perfusão, gerando redução na força muscular (FM). FM está diretamente relacionada à capacidade funcional (CF), medida que representa movimentos funcionais habituais. Objetivo: Verificar associação entre força muscular e capacidade funcional em indivíduos hipertensos. Metodologia: Estudo de corte transversal, com sujeitos hipertensos (PAS≥140mmHg e/ou PAD≥90mmHg), ambos os sexos. FM foi avaliada através da Força de Preensão Palmar (FPP) com Dinamômetro Jamar®, conforme o protocolo do American Society of Hand Therapists (ASHT). A CF foi avaliada a partir da distância percorrida (DP) no teste de caminhada de seis minutos (TC6'). Para verificar associação entre FPP e DP foi utilizado o teste de correlação de Spearman, com nível de significância de 5%. Este projeto foi aprovado pelo Comitê de Ética-Bahiana sob o número de protocolo 413.317, CAAE n° 16952113.0000.5544. Resultados: Dos 29 participantes analisados, idade média foi de 47,6±7,6 anos, sexo feminino (72,4%), com 12 ou mais anos de estudo (55,2%), nunca fumaram (75%), em uso de medicação (77,80%). PAS média foi de 125,56±18,89mmHg e PAD de 82,15±12,58mmHg. A medida de correlação entre FPP e DP foi moderada (R=0,45, p<0,05). Conclusão: Existe correlação positiva moderada entre a força muscular e a distância percorrida no TC6' em indivíduos hipertensos. No entanto, faz-se necessário avaliar o papel da hipertensão, idade, sexo e altura tanto na força muscular como na distância percorrida para entender melhor essa relação.Palavras-Chave: Hipertensão; Força muscular; Capacidade funcional.• CORRELATION BETWEEN MUSCLE STRENGHT AND FUNCTIONAL CAPACITY IN HYPERTENSIVE INDIVIDUALS AbstractIntroduction: Hypertension is a highly prevalent clinical condition that also constitutes a major risk factor in the onset of cardiovascular and cerebrovascular diseases. One of the hemodynamic effects is the reduction of energy intake by the muscles due to impaired perfusion, causing reduction in muscle strength (MS). MS is directly correlated to functional capacity (FC). Objective: To determine the association between muscle strength and functional capacity in hypertensive individuals. Methods: Cross-sectional study, hypertensive subjects (PAS≥140mmHg and / or PAD≥90mmHg), both sexes. FM was assessed by hold Palmar Force (PPF) with Dynamometer Jamar®, according to the American Society of Hand Therapists' protocol (ASHT). The FC was evaluated from the distance covered (DC) in the six-minute walk test (6MWT). To assess the association between FPP and DP the Spearman correlation test was used, with a 5% significance level. This project was approved by the BAHIANA's Ethics Committee under the number 413,317, and the CAAE number 16952113.0000.5544. Results: Among the 29 study participants, the mean age was 47.6 ± 7.6 years, 72.4% wer...
Introduction: Postural control in individuals with HTLV-1-associated myelopathy or tropical spastic paraparesis (HAM/TSP) is usually compromised, which increases the risk of falls, makes it difficult to perform activities of daily living, and impairs the quality of life. The profile of the center of gravity oscillations in this population is unknown and may aid in clinical follow-up and research. Objective: To compare the stabilometric values between HAM/TSP and uninfected individuals and verify the existence of correlations between stabilometric variables and the Berg Balance Scale (BBS). Method: A cross-sectional observational study was performed with infected individuals, classified as defined and likely (WHO criteria), compared to accompanying persons and seronegative relatives. A baropodometry platform (Footwork®) was used to obtain the oscillation values of the body’s center of gravity in total oscillation area (TOA), anterior-posterior oscillation (APO) and lateral oscillation (LO). Mean values were correlated with BBS by Spearman’s Correlation (5% alpha). Approved by the ethical committee of Escola Bahiana de Medicina e Saúde Pública under Opinion 49634815.2.0000.5628. Results: An asymmetric distribution of all the stabilometric variables analyzed in the HAM/TSP population was found, different from the uninfected group (p < 0.05). It was also possible to verify strong to moderate and inverse correlations between the variables of center of gravity oscillation with the scores obtained in BBS, especially for TOA and LO. Conclusion: People with HAM/TSP presented higher values for the center of gravity oscillations and these were correlated with the BBS in the balance evaluation.
OBJETIVO: Testar a hipótese que Palmilhas de Reprogramação Postural (PRP) melhoram a postura e podem modificar média e picos de pressão arterial (PA) em indivíduos hipertensos. DESENHO DE ESTUDO: ECR, registrado no Clinical Trials (NCT02401516), com 24 indivíduos hipertensos. CONFIGURAÇÃO: Todos foram submetidos à Monitorização Ambulatorial da Pressão Arterial (MAPA) e avaliação da postura (SAPO) no início e após seis semanas. INTERVENÇÃO: grupo intervenção (GI) utilizou PRP e grupo controle (GC) SHAM. DESFECHO PRIMÁRIO: Médias da PA. DESFECHOS SECUNDÁRIOS: Picos de PA, durante vigília e sono e ângulo posturais. A melhora da postura ocorreu quando valores angulares diminuíram ou chegaram a zero. Para comparar a PA, foram utilizados os testes t de Student, pareado e não-pareado, com nível de significância de 5%. O tamanho do efeito (TDE) foi avaliado com D de Cohen. Para postura, Wilcoxon e Mann-Whitney. Variáveis categóricas, através do teste do Qui-quadrado. RESULTADOS: As variáveis de linha de base não diferiram entre grupos. Foram obtidos os seguintes deltas: pico da PAS em vigília (+9,3mmHgVs-7,5mmHg) (p<0,05, grande TDE); pico da PAS no sono (+2,3mmHgVs-6,8mmHg) (p<0,05, TDE moderado); e pico da PAD durante vigília (+3,2mmHgVs-4,7mmHg) (p<0,05, grande TDE), GC e GI respectivamente. Para os ângulos posturais, 33% da PAS foram explicados pelo deslocamento anterior do corpo. Para a PAD, 46% e 55%, pelos ângulos de Joelho e Tornozelo, respectivamente. CONCLUSÕES: A PRP reduziu picos de PAS e PAD durante vigília, sem efeito na média da PA. Embora PRP não tenha mostrado melhora na postura geral, o deslocamento anterior do corpo e os ângulos de joelho e tornozelo explicaram 33-55% da PA mais alta.
INTRODUCTION: blood pressure System (SNS) has been considered as the ultimate integrator of the systems’ physiology on Blood Pressure (BP) control. Posture is also regulated by SNS. Systems which regulate BP also act on postural control. OBJECTIVE: To test the hypothesis of an association between postural misalignments (PM) and BP fall in hypertensive individuals. METHODS: Exploratory study using a sample of 40 hypertensive individuals, who regularly use antihypertensive drugs. All of them underwent Ambulatory Blood Pressure Monitoring (ABPM) and posture assessment, through Postural Assessment Software (PAS). To test association between posture angles and BP variables, the student’s t-test and Mann-Whitney tests were used, at a 5% level of significance. This study is registered at clinical trials, under the number NCT02401516. RESULTS: For Systolic Blood Pressure (SBP), anterior trunk shift presented smaller awake/asleep variation (14.7%vs25.3%, p=0.01), and flexing ankle for higher BP loads: 21.9%vs7.8% for total load (p=0.02), 21.8%vs9% for load during the period awake (p=0.04) and 21.9%vs7.9% for load during the period asleep (p=0.02). For Diastolic Blood Pressure (DBP), posterior trunk shift presented higher pressure load (24.0%vs16.2%, p=0.04), and anterior trunk shift presented smaller awake/asleep variation (14.4%vs25.5%, p=0.01) and flexing hip presented higher BP load (29.4%vs18.3%, p=0.02). From posture scores, the PM presented smaller awake/asleep variation for SBP (13.7%vs22.8%, p=0.03) and DBP (11.5%vs23.5%, p=0.01). CONCLUSION: PM can be associated with pressure fall. Three or more alterations in posture angles are associated with smaller awake/asleep BP variation.
