The present invention is a hemi-wheeled walker which is particularly useful with respect to hemiplegics. Patients of this type generally have one strong side of their body and one relatively weak side. Many patients have suffered from a stroke. The hemi-wheeled walker comprises an upright segment having a lower base portion extending parallel to the side of the user, with a handle at an upper portion thereof. The upright segment is a adapted for low force movement across a support surface when the user is supported on his strong side and adapted for gripping engagement with the support surface when the patient requires additional support when he is primarily supported by his weak side. A stabilizing segment is provided to one side of the upright segment and has at least one wheel at a point of contact of the stabilizing segment with the support surface. The stabilizing segment maintains the upright segment in an upright orientation and braces the upright segment against pivotting movement in a direction to the side of the user and towards the stabilizing segment. With this arrangement, the walker is designed to oppose or to minimize the patient falling to his strong side, which would be the tendency when the patient is supported on his weak leg and is moving his strong leg to the next position for walking. The low force movement of the walker across the support surface, when it is not used as a support aid, is highly desirable, as the patient is moving the walker generally with one hand and may otherwise have some difficulty in lifting and repositioning of the walker. It must be appreciated that many patients of this type are recovering and can be at various stages of recovery and often lack confidence. The support aid must be reliable and instill the confidence in the patient.
