“…Populations with injury, illness, or disease may produce very different results. Investigators have examined therapeutic WBV in populations with osteoporosis 35,36 and obesity, 37,38 but few 39 have examined the effect of WBV on blood-flow and oxygenation measures in special populations. Research needs to be conducted on the dose-response of WBV after repeated treatments and the training effects of WBV on measures of blood flow and muscle oxygenation.…”

Context:The use and popularity of whole-body vibration (WBV) has increased in recent years, but there is a lack of consensus in the literature about the effectiveness of the treatment.Objective: To quantitatively examine the effects of WBV on muscle oxygenation and peripheral blood flow in healthy adults.Data Sources: We searched Web of Science and PubMed databases and reference lists from relevant articles using the key terms whole body vibration, whole-body vibration, WBV, blood flow, peripheral blood flow, oxygenation, muscle oxygenation, circulation, circulatory, near infrared spectroscopy, NIRS, and power Doppler. Key terms were searched using single word and combination searches. No date range was specified.Study Selection: Criteria for inclusion were (1) use of a commercially available WBV device, (2) a human research model, (3) a pre-WBV condition and at least 1 WBV experimental condition, and (4) reporting of unstandardized means and standard deviations of muscle oxygenation or peripheral blood flow.Data Extraction: Means, standard deviations, and sample sizes were extracted from the text, tables, and figures of included studies. A total of 35 and 90 data points were extracted for the muscle-oxygenation and blood-flow meta-analyses, respectively. Data for each meta-analysis were combined and analyzed using meta-analysis software. Weighted, randomeffects meta-analyses using the Hedges g metric were completed for muscle oxygenation and blood flow. We then conducted follow-up analyses using the moderator variables of vibration type, vibration time, vibration frequency, measurement location, and sample type.Data Synthesis: We found 18 potential articles. Further examination yielded 10 studies meeting the inclusion criteria. Whole-body vibration was shown to positively influence peripheral blood flow. Additionally, the moderators of vibration type and frequency altered the influence of WBV on blood flow. Overall, WBV did not alter muscle oxygenation; however, when the measurement site was considered, muscle oxygenation increased or decreased depending on the location.Conclusions: Acute bouts of WBV increase peripheral blood flow but do not alter skeletal muscle oxygenation. Vibration type appears to be the most important factor influencing both muscle oxygenation and peripheral blood flow. Key Words: interventions, modalities, circulatory system Key PointsAn acute bout of therapeutic whole-body vibration (WBV) increases peripheral blood flow but does not alter muscleoxygenation levels. Vibration type and frequency affect peripheral blood flow and muscle oxygenation during an acute bout of WBV. Additional work examining the effects of WBV on circulatory measures in injured populations is needed. Although WBV is promising when used in healthy people, clinicians should be cautious in applying WBV as a therapeutic modality to improve vascular measures after injury or illness.O ver the past decade, the incorporation of wholebody vibration (WBV) into fitness and injury treatment programs has expanded rapidly.1,2 R...

“…In regards to bone-related variables measured by pQCT, there are two studies that tested the effects of 6 and 12 months of WBV therapy in postmenopausal women, 28,29 showing both of them no changes in bone characteristics following the training period. In this respect, our results show that a short-term WBV training programme led to a slight weakening of some bone geometry parameters, especially at the tibia, in elderly men and women.…”

“…Twelve months of whole-body vibration therapy showed no significant effect on bone outcomes in healthy postmenopausal women assessed by high-resolution pQCT and DXA compared to no vibration therapy (58). Another study involving healthy men and women ranging in age from 65 to 102 years did not show any significant benefit of daily 10 minutes of vibration therapy after 24 months intervention compared to placebo on the basis of QCT-derived volumetric BMD at the hip and spine (21).…”

Rational and Objectives Low intensity vibration (LIV) may represent a nondrug strategy to mitigate bone deficits in patients with end-stage renal disease. Materials and Methods Thirty end-stage renal patients on maintenance hemodialysis were randomized to stand for 20 minutes each day on either an active or placebo LIV device. Analysis at baseline and completion of 6-month intervention included magnetic resonance imaging (tibia and fibula stiffness; trabecular thickness, number, separation, bone volume fraction, plate-to-rod ratio; and cortical bone porosity), dual-energy X-ray absorptiometry (hip and spine bone mineral density [BMD]), and peripheral quantitative computed tomography (tibia trabecular and cortical BMD; calf muscle cross-sectional area). Results Intention-to-treat analysis did not show any significant changes in outcomes associated with LIV. Subjects using the active device and with greater than the median adherence (70%) demonstrated an increase in distal tibia stiffness (5.3%), trabecular number (1.7%), BMD (2.3%), and plate-to-rod ratio (6.5%), and a decrease in trabecular separation (−1.8%). Changes in calf muscle cross-sectional area were associated with changes in distal tibia stiffness (R = 0.85), trabecular bone volume/total volume (R = 0.91), number (R = 0.92), and separation (R = −0.94) in the active group but not in the placebo group. Baseline parathyroid hormone levels were positively associated with increased cortical bone porosity over the 6-month study period in the placebo group (R = 0.55) but not in the active group (R = 0.01). No changes were observed in the nondistal tibia locations for either group except a decrease in hip BMD in the placebo group (−1.7%). Conclusion Outcomes and adherence thresholds identified from this pilot study could guide future longitudinal studies involving vibration therapy.

Effect of 12 Months of Whole-Body Vibration Therapy on Bone Density and Structure in Postmenopausal Women

Abstract: Whole-body vibration therapy at 0.3g and 90 or 30 Hz for 12 months did not alter BMD or bone structure in postmenopausal women who received calcium and vitamin D supplementation.
