'Vibrating platform' cuts fracture risk

The platform helps improve bone density

A study presented to the National Osteoporosis Society at its conference in Bath suggests standing on the Optimass device helps build up bone density in the children's legs.

Children with conditions like cerebral palsy are prone to suffering fractures because they have low bone mineral density, which is linked to their lack of activity.

The platform treatment made in the US by Exogen, part of Smith and Nephew, helps redress the problem.

Improved bone density

The device is made up of a 30cm square heavy-duty plastic platform covering a series of springs.

The child can hold onto handlebars, like those on an exercise bike, and it can be very gently vibrated using a control panel.

It was initially tested on animals in the US.

Twenty children aged four to 19 took part in the UK study.

They either stood on active or inactive plates for 10 minutes a day, five days a week for six months.

At the end of the study, all the children who had stood on the active plates had increased the bone density in their legs, while none of those who had stood on the inactive plates saw any improvement.

Further trials of the device are planned.

Dignity 'crucial'

Richard Parnell, head of research and public policy for Scope, the organisation for people with cerebral palsy, told BBC News Online: "I am encouraged by the results of the research, but want more evidence of it's effectiveness.

"Also it is important that any treatment that may result from this work is carried out in a way that maintains the dignity of disabled people.

"Too often people with cp, especially children have been subjected to treatment that is under-researched and based on spurious science whilst at the same time costing a lot of money to deliver and having dubious outcomes."
