Nerve swap helps patients use damaged arms again
 

BEIJING: A kind of nerve swap, cutting a damaged nerve and moving a healthy nerve into its place, helped patients regain the use of partly paralyzed arms, Chinese surgeons reported Wednesday. Patients who got the surgery were able to once again tie their shoes and use mobile phones with a once-useless hand and arm, the team reported in the New England Journal of Medicine. The surgeons believe they have helped the body rewire the nerves to make the damaged arm useful again. But critics say it?s not clear what caused the dramatic effects and say it will take more testing in more patients to see how useful the new technique will be. And it?s also not clear how many patients could benefit from such an approach.
