Weird but true: I've read several posts about wearing a chest strap. I am a C-5/6 with some balance, but I had a friend who was a C4/5.
I have never worn a chest strap, but my friend always wore one. For some unknown reason, when by himself, he decided to go down a steep hill by his barn. The area was grass and the front wheel sunk into the ground throwing him forward. The foot rests of his wheelchair kept him from falling forward, but there he was his body stuck in midair. They found him several hours later, but too late as the chest strap would not allow him to breathe. Just weird but true.
