Effects of 12-week whole-body vibration exercise on fatigue, functional ability and quality of life in women with systemic lupus erythematosus: A randomized controlled trial.

BACKGROUND: Systemic lupus erythematosus (SLE) is a complex rheumatic autoimmune disease characterized by periods of exacerbations that can present damage in organs with important clinical manifestations. OBJECTIVE: The aim of this study was to evaluate the effect of 12-week whole-body vibration exercise (WBVE) on the fatigue, functional ability and quality of life of women with systemic lupus erythematosus (SLE) in chronic glucocorticoids use (CGU). METHODS: Twenty-one women were allocated randomly in the WBVE group or isometry group. The participants of WBVE group were positioned on the vibrating platform with 130° knee flexion and received the intervention twice a week for 12 weeks. The isometry group performed the same position and time, but without the stimulus of mechanical vibration. Fatigue, functional ability and the quality of life were evaluated at weeks 0, 6, and 12. RESULTS: From a sample of seventy-seven individuals, seventeen participants completed the study, 8 in WBVE group and 9 in isometry group. Fatigue reduced in the WBVE group at 6 and 12 weeks of intervention (p = 0.04) and (p = 0.03) respectively. There was a significant improvement in the functional ability evaluated by the Health Assessment Questionnaire in the WBVE group compared to the isometry group (p = 0.03). CONCLUSION: WBVE would be a useful intervention for control of fatigue and improvement of the functional ability of women with SLE in CGU.

Evaluation of the temperature of posterior lower limbs skin during the whole body vibration measured by infrared thermography: Cross-sectional study analysis using linear mixed effect model.

BACKGROUND: Whole body vibration exercise (WBVE) has been shown to improve muscular strength and power, and increase peripheral blood flow. The aim of this study was to evaluate the behavior of the skin temperature (Tsk) on regions of the lower limbs from an acute bout of WBVE. METHODS AND FINDINGS: Cross-sectional study approved by local ethics committee (Certificado de Apresentação para Apreciação Ética-CAAE-19826413.8.0000.5259) and Trial registration (Registro Brasileiro de Ensaios Clínicos-REBEC-RBR-738wng). Using Infrared thermography (IRT), Tsk and thermal symmetry of the posterior lower extremities (thigh, knee, calf and heel) were examined in 19 healthy participants. IRT was assessed during 60-second WBVE exposures of 0, 30 and 50 Hz. From the adjusted linear mixed effects model, vibration frequency, time and regions of the lower extremity were significant (p<0.001). However, the variable laterality was not significant (p = 0.067) and was excluded from the adjusted statistical model. The adjusted model was significant (p<0.00001) and all variables in the model were significant (p<0.01) indicating that Tsk decreases with time, independently of the vibration frequency. The value of the Pseudo-R-Squared for the model was 0.8376. The presented mathematical model of the current study may be useful to justify the patterns observed for all vibration frequencies between and 0 and 50 Hz. The main limitations of the study were the reduced time of the intervention and not having evaluated other regions of the body. CONCLUSIONS: The acute exposure of 60-second mechanical vibration has effect on the behavior of Tsk of the posterior region of the lower limbs, which is likely to be associated with a decrease on the blood flow due to WBVE. It is speculated that during WBVE a greater supply of blood is required where the body responds by shunting blood flow from the skin to working muscle in the first seconds of exercise. Further investigative work is required to verify this hypothesis.

Whole body vibration exercise in the management of cancer therapy-related morbidities: A systematic review.

The purpose of this systematic review was to investigate the effects of whole body vibration (WBV) exercise in the management of cancer therapy-related morbidities. The PubMED and PEDro databases were used to access publications published in English about the use of whole body vibration (WBV) exercises in cancer patients until February 22nd 2017. The studies included were classified according to the level of evidence (LE) by the National Health and Medical Research Council Hierarchy of evidence and the methodological quality (MQ) by the PEDro scale. The four included studies (2 of them with "high" LE-II and MQ) were performed in patients with different types of cancer (i.e. breast, lung, prostate, solid or hematological), treated with WBV exercise to counteract the cancer therapy-related morbidities. The variables evaluated were muscle activity, subjective rate of perceived exertion, exercise capacity, muscle strength, quality of life, resting urinary incontinence and severity of peripheral neuropathy. Although WBV exercise appears to be a potential treatment procedure of cancer therapy-related morbidities, further additional studies are required to determine specific and tailored protocols to be used in the different stages of the disease.

Capacidade funcional: estudo prospectivo em idosos residentes em uma instituição de longa permanência / Funtional capacity of elderly people living is a long-term care facility: a prospective study

A Short Physical Performance Balance - SPPB vem sendo utilizada largamente em pesquisas sobre o envelhecimento, como instrumento prático e eficaz na avaliação do desempenho físico e rastreamento de idosos com riscos futuros de incapacidades. Ela avalia o desempenho de membros inferiores em três aspectos: força muscular, marcha e equilíbrio, reconhecidos como componentes fundamentais para a qualidade de vida, sendo aceitos como indicadores universais do estado de saúde em idosos. Objetivo: Analisar a eficácia da SPPB em detectar alterações na capacidade funcional do idoso institucionalizado e como esta é influenciada pelas variáveis cognitivas, clínicas e funcionais globais. Metodologia: estudo prospectivo do qual participaram 30 residentes de uma instituição de longa permanência, filantrópica, em São Paulo (17 mulheres e 13 homens), com idades acima de 60 anos ou mais (43% maiores de 80 anos) e média de sete anos de residência. Após 18 meses, estes idosos foram reavaliados e os dados, comparados. Resultados: Dos idosos avaliados que obtiveram bom desempenho (17%), todos apresentaram perda de força ao longo do seguimento. Quanto ao equilíbrio e marcha, notou-se melhora de 16% e 1%, respectivamente. Apresentaram uma ou mais quedas, 47% dos sujeitos. Quando comparada com o Índex de Independência nas Atividades de Vida Diária de Katz, a SPPB se mostrou mais sensível em relação ao declínio funcional, apontando 39% em comparação aos 14% de perda identificada pelo Katz. Conclusão: os dados corroboram estudos anteriores, que apontam para o declínio da capacidade funcional de idosos institucionalizados e para a aplicabilidade da SPPB na rotina de acompanhamento funcional dessa população.
