I'm trying to figure out what this means regarding loss of use of foot. VA definition, "Will be held to exist when no effective function remains other than that which would be equally well served by an amputation stump at the site of election below elbow or knee with use of a suitable prosthetic appliance The determination will be made on the basis of the actual remaining function of the hand or foot, whether the a cts of grasping, manipulation, etc.,in the case of the hand, or of balance and propulsion, etc., in the case of the foot, could be accomplished equally well by an amputation stump wit prosthesis." Because of my COPD my rapid depletion of oxygen requires me to use walkers, wheelchairs, oxygen tanks or other devices for me to move from place to place. I am 100% servicew connected for COPD, 30% for PTSD and 10% for hearing. Does this functionally mean that I have loss of use of a foot or both? I still deplete oxygen rapidly when using a walker but not in the wheelchair. I want to apply for an Automotive grant or Adaptive equipment.
