I'm very to hear about your husband.... thats awful....

I'm not an MD - but developed severe PN 6 years ago which has not only made me loose feeling in my feet and hands, but severey affected my balance.....

I used to ride motorcyles extensively - and you need good balance plus your feet (to shift and brake) and hands (throttle, clutch, and gas) and very good balance to stay upright....

Thats one of the activities I think I miss the most with the PN - but its a must for me....

Again, I'm sorry this happened to him - accidents are by nature accidents..... just sending some good thoughts for you....
