Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Both tested and subject were blinded to allocation. Allocation concealed by sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified allocation (years since menopause, medications, exerciser status) using a randomization table created by a computer software
Masking / blinding

Summary
Brief summary
The primary purpose of the study is to investigate the effects of vibration platform training on bone health in postmenopausal women. The primary hypothesis is that vibration training will be associated with an increase in blood borne markers of bone metabolism after 8 weeks.
