i know there is a lot of posts on this topic already on here, with very reassuring answers. I was fitted with my device 7 years ago at the age of 40, in sunny Spain. I have weight trained and exercised for the last 25 years so I was devestated when the doctor told me I could no longer do weights. His reason was the constant repetitions would damage the cables. At first he was non negotiable however after a year he said I could do some curls. Fortunately I found this site and realized that doctors options vary greatly, obviously in Spain they border on the excessive side. I resumed training, and haven’t had a problem. My question is,If the cables were to be damaged would we get some sort of indication or symptoms? Is it possible that the device would abruptly stop working due to a lead fracture? Sorry for the long ramble!
