"‘Standing’ means to stand upright with at least one biological foot on the ground with or without suitable
aids and appliances (note – a prosthesis is considered an appliance, so a
claimant with a unilateral
prosthetic leg may be able to stand, whereas a bilateral lower limb
amputee would be unable to stand under this definition)."
In other words, if you have two artificial legs you should say you cannot
stand at all, however bizarre this seems.
