Kate may never walk again after sleepwalking and falling down stairs

She went to bed without a care - and woke up in agony, paralysed with a broken back after falling down the stairs.

Kate Sell remembers nothing about the accident - which happened when she was sleepwalking. She's now having intensive treatment at the spinal injuries unit in Salisbury, but doctors say it's unlikely she'll ever walk again.
