The challenge


Rosemary from Amersham suffered a stroke and was unable to lift her right leg onto a stairlift footplate or to hold it there while the stairlift was in motion. We designed a leg lifting device with a cushioned bar that rests across her left thigh and another that goes under her right thigh. Rosemary moves a lever to the left to raise the bar on the right, lifting her right leg using the bar on the left as a fulcrum; this action also moves a curved bar across her right shin. Pushing the lever forward moves the shin bar to gently bend the right knee, bringing her right foot onto the footplate and allowing her to keep it in position by flexing her left ankle to adjust the fulcrum. Rosemary can now use the stairlift on her own, giving her independent upstairs access.
