RESUMO
Vascular endothelium insults caused by high serum glucose levels affect the oxygen supply to tissues, via the microvascular endothelium, resulting in an increased perfusion heterogeneity. These insults may lead to the underuse of blood capillaries, while other vessels are overused and effectively overload their oxygen supply capacity, which eventually causes damages to distal parts of the peripheral nervous system. Therefore, the proprioceptive and exteroceptive feedback information will be gradually lost and contribute to a mobility reduction. This study aims to assess the efficacy of whole-body vibration (WBV) associated with strength training (ST) on lower-limb blood flow and mobility in older adults with type 2 diabetes (DM2). Methods and analyses: This is a protocol (1st version) for Pa single-blind, randomized, controlled clinical trial guided by the SPIRIT guidelines. Our sample will consist of 51 older adults with DM2 randomly allocated to three groups: low frequency WBV (16−26 Hz) associated to ST (G1), WBV sham (G2) and nonintervention control (G3). The study protocol is set for a 12-week (three times per week) schedule. Primary outcomes: skin temperature using infrared thermographic imaging (ITI); mean peripheral arterial blood flow velocity (MBF) by a handheld Doppler ultrasound (DU), and functional mobility by Timed Up and Go (TUG) test. Secondary outcomes: quasi-static posture using the DX100 BTS Smart optoelectronic system, and plantar pressure and body balance using the MPS stabilometric platform. Data will be collected and analyzed at baseline and post-intervention, considering p-value < 0.05 level of significance. The analyses will also be conducted with an intention-to-treat method and effect size. Dissemination: All results will be published in peer-reviewed journals as well as presented in conferences.
RESUMO
Osteoporosis and the risk of falls increase the risk of fractures and events of falls. Prescriptions and programs for different forms of exercise have different impacts on the risk of falls, and exercises from multiple categories of whole-body vibration can be effective. This study aims to evaluate the effectiveness of whole-body vibration (WBV) protocol combined with multicomponent training (MCT) in elderly women with osteoporosis and their history of falls. Our proposal is a protocol for a randomized clinical trial, divided into two stages: First, development of a protocol for WVB combined with MCT for elderly women with osteoporosis and a history of falls, under the Guidelines of the American College of Sports Medicine, and following the recommendations of the Standard Protocol Items Recommendations for Interventional Trials (SPIRIT), and second, a randomized controlled clinical trial following the Consolidated Standards of Reporting Trials (CONSORT). This trial will have implications for the effectiveness of a vibration protocol combined with multicomponent exercise on the risk of falls and quality of life for older women with osteoporosis. We expect that adding full-body vibration to an exercise protocol will decrease the risk of falls and improve participants' quality of life, as well as their strength, balance, and functional capacity.
RESUMO
Este estudo teve como objetivo analisar perfil de idosos atendidos em laboratório de pesquisa em fisioterapia do Recife. Foi um estudo descritivo, longitudinal e retrospectivo que analisou prontuários de pacientes idosos ≥ 60 anos, datados entre 2009-2019. As variáveis coletadas foram sociodemográficas, clínicas e antropométricas, e a análise dos dados foi realizada no SPSS, versão 23.0, utilizando análise descritiva. As variáveis categóricas estão expressas em frequência absoluta e relativa, e as quantitativas em média e desvio padrão. Foram analisados dados de 187 idosos, com média de idade 68,88 ±6,47; 154 (82,4%) eram do sexo feminino; 80 (43%) eram casados e 122 (52%) residiam em Recife. Das cidades da região metropolitana, Jaboatão dos Guararapes apresentou grande concentração dessa população. Os desfechos apresentaram uma população que está acima do peso e cujo diagnóstico predominante foi osteoporose. Dentre as comorbidades frequentemente associadas estão a hipertensão arterial sistêmica, obesidade, artrose, dores articulares e diabetes. O perfil de idosos atendidos na Universidade Federal de Pernambuco foi importante para identificar as principais características dessa população, suas comorbidades e assim nortear abordagens clínicas de suporte ao Sistema Único de Saúde (SUS).
This study aimed to analyze the profile of elderly people seen in a physical therapy research laboratory in Recife. It was a descriptive, longitudinal, and retrospective study that analyzed medical records of elderly patients ≥ 60 years old, dated between 2009-2019. The variables collected were sociodemographic, clinical, and anthropometric and data analysis was performed in SPSS, version 23.0, using descriptive analysis. Categorical variables are expressed in absolute and relative frequency, and quantitative variables in mean and standard deviation. Data from 187 elderly people were analyzed, with a mean age of 68.88 ± 6.47; 154 (82.4%) were female; 80 (43%) were married and 122 (52%) lived in Recife. Of the cities in the metropolitan region, Jaboatão dos Guararapes showed a large concentration of this population. The outcomes presented a population that is overweight and whose predominant diagnosis was osteoporosis. Among the comorbidities frequently associated are systemic arterial hypertension, obesity, osteoarthritis, joint pain, and diabetes. The profile of elderly people attended at the Federal University of Pernambuco was important to identify the main characteristics of this population, their comorbidities and thus guide clinical approaches to support the Unified Health System (UHS).
RESUMO
BACKGROUND: The purpose of this study verify the immediate effect of whole body vibration (WBV) on quadriceps muscle strength, functional mobility and balance in elderly patients with Osteopenia and/or Osteoporosis. METHODS: This was a randomized pragmatic clinical trial with 34 elderly (32 women) randomly assigned to two groups: the experimental group (EG; n = 17) who underwent low-frequency (16 Hz) WBV and the control group (CG; n = 17) who performed the walk. Outcome measures were: quadriceps muscle strength measured by a maximal repetition test (1RM); functional mobility assessed by the Timed Up and Go (TUG) test and balance assessed by the Berg Balance Scale (BBS). RESULTS: In within-group interaction, a significant increase was observed in quadriceps muscle strength (EG:p = 0.047) and balance (EG: p = 0,012; CG: p = 0,007). In between-groups interaction, a significant difference was not observed. There was an increase in the muscular strength of the EG and in the balance in both groups. CONCLUSION: An WBV training session was able to alter the muscular strength of the LQ and the balance of the elderly with Osteopenia and/or Osteoporosis. It is suggested, however, that future studies involving larger sample number and/or populations should be developed to analyze the short-term effects of WBV.
