When stroke or other conditions cause paralysis or weakening of one side of the body, rehabilitation processes often include prescribing a hemi-height adjustable wheelchair for increased levels of independence. There are two wheel positions on this type of wheelchair, one that lowers the seat, bringing the individual closer to the ground. This lower seating position allows both feet to touch the ground completely, thereby allowing the individual, even those small of stature, to propel themselves with one or both feet, depending on how the body was affected from the hemiplegia (one side of body paralyzed) or hemiparesis (one side of body weakened).

While most providers of mobility equipment will adjust the chair, the process is not a complicated one, involving the loosening of bolts and removal of wheels. The hemi-height wheelchair comes already equipped with a crossbar for stability and the appropriate sets of sockets for the two heights.

Adjustable arm heights may also be available on certain makes and models of hemi wheelchairs. This added feature is useful for the individual who has limited use of an arm or hand, or none at all in the case of full paralysis. Bringing the individual closer to the wheel on the healthy side of the body will prevent additional physical problems often caused when the person leans over the arm of the wheelchair to reach the wheel.

In some cases, removable arms are required to allow for unencumbered transferring of the individual into the wheelchair. The use of pivot discs or transfer boards is common for those who use a wheelchair more than two hours a day.

Hemi wheelchairs are available in the standard seat width of 18 inches and one for smaller individuals that measures 16 inches. Some manufacturers have a basic hemi model that accommodates a 20 inch wide seat. Generally larger or smaller widths require a more customized approach that will most likely be more costly.

Medicare and other insurances have eligibility requirements for wheelchairs and other durable medical equipment. Individuals should check with their providers before purchasing the device as insurance companies often have a strict set of policies for coverage.
