Rabbit Lever (Toilet Extension Lever)

We made this for an older person whose falls at home had been increasing because of weakness in the lower limbs and reduced standing balance. There is a handrail in the toilet at home, but operating the toilet flush lever requires a large shift of the center of gravity, which creates a risk of falling. The care manager in charge asked us whether the lever could be made longer, and we made this. By attaching the Rabbit Lever (extension lever), the grip is closer to the person, so forward bending of the upper body decreased. Because the lever is longer, the principle of leverage let them move it with less force than before. The user was surprised, saying "It's light, that's great." Being able to operate it with light force reduces awkward shifts of the center of gravity and should also help prevent falls.
