  • Publication number: 20080077066
    Abstract: An AFO for automatically lifting the toes about the phalanges joint to assist a person when they have a medical condition referred to as “drop foot” comprising, in combination, a support that transcends vertically between two points on the lower front leg, a primary tension member attached to the upper point with a snap swivel leads to where it is fastened to the toe of a shoe at an optimum location just above the big toenail and a secondary tension member placed over the primary member so that it aids in lifting the toes and keeping them lifted. A lower strap holding the support to the front of the leg in the vicinity of the ankle does so in a spiral manner, preventing a “choking” effect that would impede circulation. The entire device is lightweight, easy on/off, comfortable and doesn't need to go in a shoe.
