We report the case of a patient who had a transtibial amputation and whose
wheelchair had been inadvertently fitted with a push-to-lock brake on one s
ide and a pull-to-lock brake on the other. During a standing-pivot transfer
from bed to wheelchair, during which the patient thought that she had appl
ied both brakes, the wheelchair turned away from the patient toward the sid
e of the unlocked brake and the patient fell to the floor. This case report
has implications for wheelchair design, wheelchair system management, and
for user training.
