A PubMed search for every randomized trial and pooled analysis of whole-body vibration on bone density found the two largest independent trials null: Slatkovska et al.

Five meta-analyses disagree site by site. Mixed results with failed large trials meet the written C definition. EBL is paid a commission on a vibration plate listed under this therapy; this change was made through the logged review that payment requires, and it lowers the letter.PMID 22084333 PMID 25581217
The record carried a not-replicated flag while its B rested on a 2026 meta-analysis of randomized trials on bone mineral density (Chen et al., BMC Musculoskelet Disord, 2026; PMID 41559705). The flag describes a single trial nobody has repeated; a meta-analysis of independent randomized trials is replication The same finding reproduced by a separate research group. A result seen once can be chance or bias; a replicated one is harder to explain away. by definition, and what caps this letter at B is the endpoint The outcome a trial measures to decide whether the treatment worked, such as heart attacks, blood pressure or a symptom score., not the absence of a second trial. Flag removed, letter unchanged. Applied the written grade definition under the editor's standing instruction of October 2026 (Arnold Sandlow, D.C.).PMID 41559705

Whole body vibration means standing on a platform that shakes rapidly. It has been tested to strengthen bones in older adults, mostly women after menopause. The two largest outside studies found no change in bone density. Reviews of the studies disagree on whether any part of the skeleton changes at all.

Why this gradeGrade C, small or unreplicated trials. The reasoning, and what the grade does not cover.
Grade C on bone mineral density in older adults, mostly postmenopausal women. The two largest independent randomized trials were null (Slatkovska et al., 2011; PMID 22084333; Kiel et al., 2015; PMID 25581217), and the meta-analyses disagree on which sites change, if any (Jepsen et al., 2017; PMID 29289937; Harijanto et al., 2022; PMID 34781288; Massini et al., 2025; PMID 40391029; Chen et al., 2026; PMID 41559705; de Oliveira et al., 2023; PMID 36282343).
WHY NOT BB needs a good trial supported by further trials, and here the best-run trials did not find the effect.
WHAT THIS GRADE DOES NOT COVERfractures, which no cited trial was powered to measure; falls, which need their own search; muscle strength; men, who were few in the trials; and any specific platform, frequency or session length.

The evidence, in fullSeven papers, each linked to its PubMed record.
Slatkovska et al. (Annals of Internal Medicine, 2011; PMID 22084333): 202 postmenopausal women with low bone density, 20 minutes a day of vibration at 90 Hz or 30 Hz or no vibration for 12 months, assessors blinded: no effect on any bone outcome at the hip or spine. Kiel et al. (Journal of Bone and Mineral Research, 2015; PMID 25581217), VIBES: 174 adults with a mean age of 82, active or placebo platform for 24 months: no difference in hip or spine bone density or bone turnover markers. Jepsen et al. (BMJ Open, 2017; PMID 29289937), 14 trials: no overall effect on bone density. Harijanto et al. (Gerontology, 2022; PMID 34781288): no significant effect at the hip or lumbar spine. Massini et al. (PeerJ, 2025; PMID 40391029): a small effect at the total femur only. Chen et al. (BMC Musculoskeletal Disorders, 2026; PMID 41559705), 14 trials, 1,447 participants: gains at some hip sites and L2 to L4, none at L1 to L4 or the total hip, and 79% of trials at some risk of bias. de Oliveira et al. (Osteoporosis International, 2023; PMID 36282343): lumbar spine gains only in subgroups using particular settings. Mixed results with null large trials: Grade C.
Balance (Berg Balance Scale or Timed Up and Go) at baseline and 8 weeks. Bone density (DEXA) at baseline and 12 months if osteoporosis is the primary indication. Session frequency, duration, and vibration parameters (Hz, amplitude): the published trials most consistently used 25-35 Hz vertical vibration for 10-15 minutes per session.

Products carry no letter. The letter belongs to the therapy as the trials studied it, and no trial tested these products unless the entry says so. Listed alphabetically; payment does not affect order.
Consumer-grade vibration platform with good frequency range. Oscillation + spiral vibration modes. More accessible price point for home use. Adequate for balance and mobility protocols.
Most-studied WBV platform in peer-reviewed literature. Tri-planar vibration at 25–50Hz. Used in clinical research on osteoporosis and sarcopenia Age-related loss of muscle mass and strength. prevention. Professional-grade build quality.
Vertical vibration platform. The Whole Body Vibration grade rests on bone mineral density gains at some skeletal sites in older adults. BMD is an objective surrogate, not a fracture outcome, and no trial has shown that vibration reduces fractures.
Not matched to the studied protocol. The Whole Body Vibration grade rests on a meta-analysis of 14 trials in older adults that used a range of platforms and settings, so no single frequency or amplitude defines what was studied, and EBL has not verified this plate's frequency and amplitude against those trials.
This page carries a letter. EBL takes no commission, referral fee or payment of any kind on anything it grades. No letter has been bought and none is for sale. Products listed under this modality may be commercial partners, and their purchase links may earn EBL a commission. Those products carry no letter of their own, every relationship is disclosed beside the link, and where a product does not deliver what the trials tested, this page says so regardless of who pays.
How this is enforced
That is not a promise, it is a build condition. Two checks run on every deploy: one refuses to publish if a commission is claimed on anything graded, the other refuses if a page names a commercial relationship that is not declared in the register. If either fails, this page does not go live. You can read how the checks work, and what they do not cover, on the evidence integrity page.
