A pneumatically-powered device designed to support and lift a disabled (paraplegic) patient to an upright standing position to provide the health benefits associated with standing (e.g., improved breathing, circulation, digestion, and flexibility); it is not intended to facilitate gait. It typically consists of a seat, sling and/or platform with appropriate supports (e.g., footplates, kneepads, chest pad), a compressed gas cylinder, and a pneumatic lifting mechanism to raise the patient from a supine, prone, and/or seated position to standing. It includes wheels for reorientation and may include a manual mechanism to allow the occupant a degree of mobility.
