ABSTRACT:
A wheelstand comprises a frame including a pair of lateral supports in spaced, parallel arrangement. A pair of large drive wheels are rotatably secured at the rear ends of the lateral supports and a pair of castor wheels are secured at the front ends of the lateral supports. A user support structure or a prone board comprising a pair of elongated rails, spanned at one end by a chest pad, is pivotably secured to the lateral supports for pivoting between at least an upright or vertical position and a prone or horizontal position. The wheelstand includes a pair of adjustable knee pads and a posterior pelvic stabilizer, or an elongated, curved seat pivotably attached to a bar. A pair of optional thoracic lateral pads extend from the sides of the chest pad to stabilize the trunk laterally and to support the trunk in the midline position. Also optionally provided is a posterior thoracic panel for attaching to the lateral pads by a strap and an anterior abdominal pad. At the end of the prone board opposite the chest pad are provided foot plates. In an alternate embodiment of the present invention, the foot plates may be left off, thereby converting the wheelstand into a wheelstand-walker.
