A simple, cheap procedure for repairing damaged nerves in the leg can help paralysed rats walk normally within a few days – a dramatic reduction in recovery time. Within minutes of the rats waking up after the operation, they began to move their damaged limb, and 98 per cent of them had recovered 60 to 70 per cent of leg function within two to four weeks. Conventional treatments would never give the rats such a level of recovery.
