Disabled twins Katie and Emma Sutcliffe have been taking their first tentative steps since pioneering surgery to help them walk unaided.
The 16-year-olds suffer from spastic diplegic cerebral palsy and need wheelchairs to get around.
It is hoped that the treatment they are currently undergoing at St louis Children’s Hospital in Missouri, America, will see them walk unaided for the first time.
The twins and their family and friends raised more than £85,000 through a Guardian-backed appeal to pay for the surgery.
The girls have undergone two operations, firstly to reduce tightness in their leg muscles and then to lengthen their leg tendons.
They are now undertaking intensive physiotherapy as part of the treatment, and will remain in Missouri until August 5.
The twins’ mum Caroline said the physio sessions were going well.
