Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Exercise group will receive a three months whole body vibration treatment. Placebo group will receive a similar treatment without vibration. During the study, all participants will receive usual inpatient care of the nursing home. Whole body vibration will be applied during one hour per week distributed between different days and consist of six static exercises with rest between exercises targeting lower limb muscles. Participants will stand on the whole body vibration or placebo platform in a semi-squat position and hold on to the railings secured onto the platform. The frequency (load) of the vibrating platform will be at 12.5 to 18.5 Hz and the amplitude will be 4 mm. The intervention will begin with two 30 seconds sets of three exercices with 30 seconds rest between exercises. The exercise volume and intensity will be progressively increased according to the overload-principle.

Comparator / control treatment
The control group will receive usual care of the nursing home and a placebo trainning. Placebo group will make the same exercises than vibration group in the placebo platform. This platform has the appearance of a conventional vibrating platform. It has a speaker hidden in the base and is connected to a computer, but it does not emit any kind of vibration.
Control group
Placebo

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be recruited from a nursing home. Eligible patients will be screened for inclusion in the study. They will be informed about the study intervention and protocol. If they agree in participate then they will be visited by a research assistant and informed consent will be obtained. Following this, they will be randomised in an intervention or placebo group. Randomisation will be ascertained by a randomisation schedule held at a distant site. This schedule will be compiled by someone with no involvement in the study to maintain the blindage. In this sense, people who apply the training to patients are different from those who will perform the initial and final measurements. Researchers conducting measurements will not know to which group each participant pertain.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation schedule will be generated using a through numeric list randomly generated within Microsoft Excel

Summary
Brief summary
In the present study we intend to apply a three months whole body vibration exercise protocol with oscillating platform in isntitutionalised older people with fear of falling.

The main aim is to test the applicability and observe improvements of this training protocol in fear of falling, balance, strength, sense to vibration and quality of life in this population. The second aim is to analyse the improvements obtained in psychological parameters (as depression, dayly living functioning), fitness, weight, body mass index, physical activity, etc. In addition we intend to evaluate if this programm is cost-efective.

This protocol could improve all variables described and could be a good, cost-efective and feasible strategy for falls prevention in institutionalized older people with fear of falling.
