Forget about whole-body vibration machines as a way to reduce bone loss.
These devices, which involve standing on an oscillating platform, have been touted as a therapy for osteoporosis, based on positive findings in animals. They are used in some medical clinics and gyms, and can be purchased for home use.
But in November a Canadian study published in the Annals of Internal Medicine involving 202 postmenopausal women with low bone density found that a year of vibration therapy had no effect on bone density or structure. The therapy also caused pain, numbness and weakness in the legs and nausea in some women.
Also in November, the Agency for Healthcare Research and Quality reviewed all the research and concluded that there is no good evidence to support the use of such devices for bone health.
