When going up stairs, the amputee found that the best method for him was to take two stairs at a time with the sound leg, and then bring up the prosthesis to the same step. While not a normal step over step ascent, this allowed the amputee to walk up steps almost as fast as able-bodied people. Another point made by this amputee is that he found that first of all, the choice of a prosthetist can make a real difference in outcome. Also, he said that once he received his leg, it could take up to a year to get the socket just right. Being able to walk well and be comfortable can take a long time with many modifications.
Persistence is key here.
This amputee also has the TEC system for a socket. He indicated that he liked it better than a previous suction socket mainly due to better comfort. He did indicate that he has a problem with sweating and the suction sockets could be periodically drained easier than the TEC system. A headwork device. Deodorant vs antiperspirant.
