Whole-Body Vibration Exercise as an Intervention to Improve Musculoskeletal Performance

The exposure of individuals to mechanical vibrations produced in vibrating platform can generate whole-body vibration (WBV) exercise. This modality of exercise represents a less tiring alternative to sport, which could benefit mechanical human behavior and prevent sports injuries and musculoskeletal disorders. The specificity of the human body, articulated and connected segments, requires to take into account the biomechanical parameters in protocols involving WBV exercise. Moreover, work time, rest time between the bouts in each session number of sessions, extension of the intervention, and week periodicity must be also well established. Responses to WBV exercise are observed at musculoskeletal, neurological, endocrinological and vascular levels. With respect to the musculoskeletal level, it is verified increase of muscle strength, endurance and power, improvement of the balance, increase of bone mineral density and the decrease of risk of falls. There are several tools to evaluate the responses of the body to WBV exercise. The aim of this chapter is to highlight the relevance of the WBV exercise as an intervention of the physical therapy for the better human optimization

EFFECT OF A SHORT PERIOD WHOLE BODY VIBRATION WITH 10 HZ ON BLOOD BIOMARKERS IN WISTAR RATS

Background: Exposure to whole body vibration exercises (WBVE), besides some biological effects, causes alterations in the concentration of some blood biomarkers. The aim of this study is to evaluate the action of vibration (10 Hz) of WBVE on the concentration of blood biomarkers in Wistar rats. Materials and Methods: Wistar rats were divided in 2 groups. The experimental group (EG) was subjected to vibrations of 10Hz (one min per day, one week, total time of seven min), while the control group (CG) has not experienced vibration. Samples of whole blood were drawn for biochemical analysis of the concentration of total cholesterol, triglycerides, HDL, LDL, VLDL, glucose, CPK, albumin, alkaline phosphates, TGP, TGO, γGT, lipase, amylase, urea and creatinine. Results: White blood cell count and a platelet-hemogram were also performed. Significant (

Cognitive parameters were improved in relation to attention, memory or learning in almost all articles evaluated in this systematic review. Conclusion: Intervention with WBV would positive effects on individuals' cognitive ability, although further randomized investigations must be conductedObjetivo: Revisar sistematicamente os mecanismos pelos quais a vibração de corpo inteiro (VCI) melhora a capacidade de aprender, pensar, memorizar e todos os outros processos que envolvem a cognição. Método: O presente estudo coletou dados de três bancos de dados usando as palavras-chave “vibração de corpo inteiro” e “cognição”. Ensaios clínicos randomizados com foco na associação de WBV e cognição foram considerados. O estudo foi registrado no banco de dados de protocolos de revisões sistemáticas PROSPERO. Todos os estudos incluídos usaram pacientes saudáveis, expostos à VCI. Os artigos incluídos foram avaliados quanto ao risco de viés de acordo com os critérios da Colaboração Cochrane, nível de evidência e força de recomendação segundo a classificação GRADE e Oxford. Resultados: Dos 89 artigos publicados, de acordo com os critérios de elegibilidade, quatro foram submetidos à extração de dados. Os parâmetros cognitivos, atenção, memória e aprendizagem demonstraram melhora em quase todos os artigos avaliados nesta revisão sistemática. Conclusão: A intervenção com VCI teria efeitos positivos na capacidade cognitiva dos indivíduos, embora mais ensaios clínicos randomizadas devam ser realizados para avaliação de tais parâmetros

Anti-viral effects of medicinal plants in the management of dengue: a systematic review

Background: Dengue is considered as an important arboviral disease. Safe, low-cost, and effective drugs that possess inhibitory activity against dengue virus (DENV) are mostly needed to try to combat the dengue infection worldwide. Medicinal plants have been considered as an important alternative to manage several diseases, such as dengue. As authors have demonstrated the antiviral effect of medicinal plants against DENV, the aim of this study was to review systematically the published research concerning the use of medicinal plants in the management of dengue using the PubMed database.Materials and Methods: Search and selection of publications were made using the PubMed database following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA statement).Results: Six publications met the inclusion criteria and were included in the final selection after thorough analysis.Conclusion: It is suggested that medicinal plants’ products could be used as potential anti-DENV agents.Keywords: Dengue, arbovirus, medicinal plants, PubMe

Acute Effects of Whole-Body Vibration Exercise on Pain Level, Functionality, and Rating of Exertion of Elderly Obese Knee Osteoarthritis Individuals: A Randomized Study

Introduction: Among chronic diseases, knee osteoarthritis (KOA) is a joint disease that causes important progressive alterations in the articular and periarticular structures, including synovial inflammation. Exercise has been suggested as an intervention to KOA individuals, and studies suggest that whole-body vibration (WBV) exercise decreases pain levels and favours the functionality of KOA individuals. Objective: The aim of the present study is to analyze the acute effects of WBV exercise on pain levels, functionality (Timed Up and Go (TUG test), anterior trunk flexion (ATF)), and rating of exertion of elderly obese KOA individuals. Methods: Thirty-seven individuals with KOA were allocated to a WBV exercise group (WBVEG), n = 19 (15 females/4 males), and a control group (CG), n = 18 (15 females/3 males). WBVEG performed one session of WBV exercise (11 min, using 5 Hz, 2.5, 5.0, and 7.5 mm, 0.12, 0.25, and 0.37 g). Three bouts were performed (working time of 3 min and rest time of 1 min) using a side-alternating vibrating platform (VP). The same position was used in CG; however, the VP was turned off and there was equipment coupled to the VP that emitted a sound like the vibrations. The pain level was evaluated using a visual analog scale (VAS). Functionality was evaluated with a TUG test and ATF. The rating of subjectively perceived exertion was measured with the category ratio CR-10 (BORG Scale CR-10), Results: A reduction of pain levels in WBVEG after the intervention (p = 0.001) and intergroups (p = 0.041) was found. A decrease of TUG test time in both groups (p = 0.001) and intergroups (p = 0.045) was found, while no statistical changes were observed in the Borg Scale score. Significant improvements of flexibility in both groups (p = 0.001) and intergroups (p = 0.043) were found. Conclusion: One session of WBV exercise can lead to important improvements in individuals with KOA, possibly triggered by physiological responses. However, more studies are needed, in this clinical context, to confirm these results

Effect of the Combined Intervention with Passive Whole-Body Vibration and Auriculotherapy on the Quality of Life of Individuals with Knee Osteoarthritis Assessed by the WHOQOL-Bref: A Multi-Arm Clinical Trial

The aim of this study was to determine the effect on the quality of life of two non-pharmacological interventions isolated or in combination: (i) passive whole-body vibration exercise (WBVE), and (ii) auriculotherapy (AT). One hundred three participants with knee osteoarthritis (KOA) were allocated to: (a) a vibration group (WBVEG; n = 17) that performed WBVE (peak-to-peak displacement: 2.5 to 7.5 mm, frequency: 5 to 14 Hz, Peak acceleration: 0.12 to 2.95 g), two days/weekly for five weeks, (b) an AT group (ATG; n = 21), stimulation of three specific auriculotherapy points (Kidney, Knee and Shenmen) in each ear pavilion, (c) WBVE + AT (WBVE + AT; n = 20) and (d) respective control groups (WBVE_CG, n = 15; AT_CG, n = 12; WBVE + AT_CG, n = 18). The participants filled out the WHOQOL-bref Questionnaire before the first and after the last sessions. Statistical differences in the various domains of the WHOQOL-bref were not found. In conclusion, WBVE or AT alone or combined did not contribute in altering the quality of life of individuals exposed to these interventions
