Abstract
A foot mobility device includes a base, a foot rest hingedly coupled to the base, and an inflatable lifting bladder between the base and the foot rest. The footrest preferably has a massage sock which contains a plurality of inflatable massage bladders. Each of the bladders is provided with a pressure sensor and is selectively coupled to a pressure source (including an air pump) by an electrically operated valve. A control circuit is electrically coupled to the valves, the sensors, and the pump. The control circuit selectively inflates and deflates the bladders according to a cycle which raises and lowers the foot rest and inflates/deflates the massage bladders. The control circuit is preferably provided with a synchronization link which is used to electrically couple two foot mobility devices (one for each foot) such that they operate in an alternating rhythm.
