Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Written informed consent will be required prior to any testing or randomisation. Assignments will be placed in sealed opaque envelopes and designated colours will be assigned for each group. The subject will open these envelopes after completion of all baseline testing. Subjects who dropout prior to completion of baseline testing will not be randomised.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Subjects are randomised after the baseline assessment has been completed to: 1. Vibration training or 2. Wait-list control. Randomisation is at the level of the individual patient, and will be stratified by age, currently taking calcium or vitamin D, current exercise status. The list will be generated and maintained by a research assistant not otherwise involved in the study. The sequential treatment assignments are based on a computer-generated randomisation scheme (by using the Web site www.randomization.com set up by Dr Gerard E. Dallal).
