Whole body vibration (WBV) has been widely used as a modality for physical activity. In fact, WBV has been used for physical rehabilitation, and to improve muscle performance; but there is little ...information about its effects on heart rate variability (HRV).
The aim of this study was to evaluate the effect of vibration on HRV of the elderly using the vibratory platform.
Eleven older adults (7 men, 4 women), aged between 60 and 75 years, were subjected to WBV. The study consisted of a single session of WBV with volunteers standing upright for 10 min on the oscillating platform, with frequency of vibration set at 20 Hz (displacement ± 6 mm; orbital vibration). Pre (baseline) and post-WBV electrocardiograph signals were acquired using a cardiac monitor; and data were statistically analyzed using paired Student's t-test or Wilcoxon test, as appropriate.
The results demonstrated an increase in SDNN (standard deviation (SD) beat-to-beat, N–N intervals), rMSSD (square root of the mean squared difference of successive N–Ns) and pNN50 (proportion of N–N50 divided by total number of N–Ns) post WBV (p = 0.032, p = 0.024 e p = 0.044, respectively), compared to baseline. The present study thus demonstrated that time domain variables (i.e., SDNN, rMSSD, and pNN50) increase post WBV.
Older individuals are at high risk of developing cardiovascular diseases. As seen in the study, WBV improves HRV; and may help reduce risk of cardiac ailments. Moreover, WBV does not require extensive physical activity on the part of the participant. This makes WBV potentially beneficial to the elderly population. Further studies on WBV using different frequencies and training schedules may improve its applicability in clinics.

***Whole body vibration and blood glucose levels in elderly people: a pilot study***AIMS: To evaluate the effect of whole-body vibration therapy on blood glucose levels of elderly people using a ...vibratory platform.METHODS: The study included volunteers of both genders, aged between 60 and 75 years, without gait disorders or motor disabilities. Individuals with systemic disease, obesity, conflicting treatments, tobacco users, and those who could not understand the maneuvers were excluded. The study consisted of a single session of whole-body vibration. Heart rate, respiratory rate, arterial blood pressure, and blood glucose were obtained for each participant at baseline, immediately before the procedure. Volunteers were then placed in the standing position on the ground of an oscillating platform and treated for 10 min with a frequency of vibration set at 20 Hz (displacement ±6 mm; orbital vibration). Immediately after the whole-body vibration session, all data were collected again. Comparisons were made between baseline and post-treatment data. Normality was tested by Kolmogorov-Smirnov test. Data were analyzed using paired Student’s t-test or Wilcoxon test as appropriate. The level of significance was set at p<0.05.RESULTS: Eleven participants (seven men, four women) participated of the study. The mean age was 64.18±4.37 years. The results showed a significant decrease in the glycemic indexes (p=0.016) and an increase in the respiratory rate (p=0.047) after the whole-body vibration session.CONCLUSIONS: Healthy elderly subjected for 10 minutes to whole-body vibration set at 20 Hz presented reduction of blood glucose levels and increasing of respiratory rate.

Dor é uma qualidade sensorial complexa, puramente subjetiva, difícil de ser definida, descrita ou interpretada. É um mecanismo de proteção do corpo, ocorre sempre que qualquer tecido estiver sendo ...lesado. As dores cervicais afetam 30% de homens e 43% de mulheres em algum momento de suas vidas. Para o alívio da cervicalgia existem evidências de que a acupuntura é efetiva através de sua técnica em estimular pontos reflexos que tenham a propriedade de restabelecer o equilíbrio, alcançando, assim, resultados na diminuição do quadro álgico. O objetivo deste estudo foi avaliar a influência de um protocolo de acupuntura sistêmica para tratamento de cervicalgia na intensidade de dor, pressão arterial e frequência cardíaca. Realizou-se um estudo clínico com 11 sujeitos, de ambos os sexos, com idade média de 32,0 ± 13,2 anos. O tratamento foi composto por 4 sessões de atendimento segmentadas em uma sessão semanal e a avaliação da dor foi realizada antes e após cada sessão através da escala visual analogica (EVA). Os resultados encontrados sugerem que a acupuntura reduziu a dor em pacientes portadores de cervicalgia após 4 semanas de tratamento.
