Among individuals with spinal cord injury (SCI), several adverse events were reported including pain, pressure sores on the feet, autonomic dysreflexia, and dizziness, which were largely attributed to the passive standing portion of the intervention.

Researchers at Lyndhurst Centre caution that Whole Body Vibration may elicit inner ear troubles, dizziness, headache, lower-limb spasticity, fracture (especially among those with severe osteoporosis), and/or hardware loosening (plates or screws as a result of surgery).(19)

A recent systematic review and meta-analysis on the effects of Whole Body Vibration on BMD in postmenopausal women concluded that Whole Body Vibration slows down bone loss at the hip (20) the benefits are similar to walking.
