Bionic legs help Elena to walk

8 November 2011 Last updated at 10:19 GMT

A new bionic exoskeleton has helped wheelchair users walk.

Elena Bertoldo has flown over from Italy to be fitted with the device for the first time.

Rex bionic legs have been designed by two Scottish school friends and have been approved for sale in the UK.

The exoskeletons should help people with spinal injuries or mobility problems.
