Abstract: An ambulation aid which has a support structure for the patient that both supports the patient's weight, and is movable laterally with respect to the frame to accommodate sideways hip movement of the patient's gait. The inventors have observed that a patient's hip will shift laterally as the patient steps forward and places weight on the forward stepping leg. This causes prior art ambulation aids to jerk sideways. The present invention overcomes this by providing a support structure which can move sideways without requiring the entire frame to move sideways. In one embodiment, the support structure slides in a track behind the patient, allowing lateral movement. In another embodiment, the support structure includes a belt which either slides through rollers behind the patient, or is attached but is flexible to allow hip movement, or is attached to a slider behind the patient.

Abstract: A multipositioning power mobility aid for physically challenged children is provided. The power mobility aid provides a transition to a power wheelchair. The power mobility aid includes a multipositioning main frame that allows a child to be placed in a sitting, semi-standing or standing position without requiring multiple adjustments. The back support rotates to a nonsupporting position to facilitate placing a child in or removing a child from the power mobility aid. The back support then locks into an upright supporting position after the child is positioned in the power mobility aid. The power mobility aid includes an adjustable arm that supports the user-operable input device in multiple locations.
