Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Both child and parent/carer who are randomised into the vibration arm of the study, will be instructed by the treating physiotherapist to use the Juvent vibration plate. They will be asked to undertake a 12 months program, to stand on the plate for 20 minutes daily.
Frequency is at a low-level (30Hz) as these forces are less than the skeleton experiences through normal ambulation,as such unlikely to result in adverse skeletal events.
Intervention code [1] 236681 0
Treatment: Devices
Comparator / control treatment
Standard treatment group:- children randomised into the control arm of the study will continue their normal level of activity with standard care, investigations as per treatment for Osteogenesis Imperfecta(brittle bones)
Control group
Active

Outcomes
Primary outcome [1] 238061 0
Muscle and Functional Measurements:-
*Peak Jump Force (PJF), Peak Jump Power (PJP) & Jump velocity, performed on the Leonardo Jumping Platform, includes a computer program for analysis.
*Maximum Force in relation to body weight, where the children are asked to do multiple one-legged jumps on the Leonardo Jumping Platform.
*Chair Raising Test, (5 time in ane cycle) sit to stand on the Leonardo Jumping Platform.
*Grip Force, using a standard hand dynamometer.
*Functional Assessment for gross-motor and self-care abilities.
* Mobility using the Bleck Score e.g 0 (does not walk - 3 (able to walk in the community).
Timepoint [1] 238061 0
Baseline, 6 and 12 months
Functional Assessment is also done at baseline, 3, 6 & 12 months.
Primary outcome [2] 238062 0
Densitometric Measurements:-
1. Peripheral Quantitive Computer Tomography (pQCT) using 3 sites of the non-dominant Tibia, analysis of total and trabecular volumetric bone mineral density.
2. Dual energy X-ray absorptiometry (DXA)using total body and lumbar spine, analysis of bone mineral content, projected bone area and lean tissue mass.
Timepoint [2] 238062 0
Baseline, 6 and 12 months
Primary outcome [3] 238063 0
Radiological Measurements:-
*Antero-posterior and lateral thoraco-lumbar spine. Cobb angle (AP) and vertebral morphometry will be assessed.
Additional x-rays only as clinically indicated e.g follow-up fractures, performed 6th monthly.
Timepoint [3] 238063 0
Baseline, (6) and 12 months
Secondary outcome [1] 242249 0
Clinical Chemistry Measurements:- the following biochemical measures are to be performed:-
Whole Blood (Full blood count), Serum and Urine. Analysis of biochemical homeostasis
Timepoint [1] 242249 0
Baseline, 6 and 12 months
Secondary outcome [2] 242250 0
Exploratory and Safety measurments
*Patient Questionaire, to evaluate the acceptibility of the whole body vibration trial.
*Physical examination, at each visit a physical will be performed, this includes weight and height measurements. growth rates will be calculated from the height measurements.
*Fracture Rates, diagnosed according to radiological evidence. Parents are asked to report by telephone within 24 hours.
*Skeletal Pain, a dairy is to be kept to record episodes of pain. The Wong-Baker FACES Pain Rating scale will be used at each visit.
*Quality of Life, using the PedsQL questionaires, according to specific age groups.
Timepoint [2] 242250 0
Baseline, 6 and 12 months

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A children with Osteogenesis Imperfecta from the hospital database and where subjects were paired by age and disease severity.
Allocation concealment by central randomisation by phone/fax/computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using procedures such as coin tossing.

Summary
Brief summary
Aims of this project:
*To investigate if whole body vibration training is effective and well tolerated over the short-to medium-term.
*Medium-term home based training program will evaluate if whole body vibration training influences:- mobility, muscle power and force, muscle mass & bone mass.
The hypothesis:-
*Is that over a six month period the aims of effectivness and tolerance can be noted in children with Osteogenesis Imperfecta.
