Canes or walking canes are just one of several devices available to assist in ambulation, or walking. Using a walking cane improves balance by increasing a person’s base of support. When used correctly, canes unload the leg opposite to the hand the cane is in by up to twenty five percent. There are four categories of canes on the market today, each providing a slightly different amount of assistance.
The C cane is a single straight walking cane with a curve forming a handle at its top. This is the most simple of all canes. It assists in improving balance by the mechanism described above. Straight canes should be used by the patient needing only slight assist with balance or only minimal unweighting of the opposite leg.
Functional grip canes are similar to the c cane except for the handle. A functional grip cane has a straight grip handle rather than a smooth curve. This allows for a better grip by the patient. Improved grip allows for better cane control and hence offers more support than the c cane. Functional grip canes are appropriate for the patient who needs slightly more balance assistance than the c cane provides.
A walking cane with a rectangle base and four small supports that contact the floor is called a quad cane. This base provides more support than the above two canes. Quad canes come in two varieties depending on the size of the rectangle base. Appropriately they are categorized as small base and large base quad canes. The quad cane is helpful for patients needing much more balance assistance than provided by the c and functional grip canes. Quad canes are often used by the person with hemiplegia, or paresis of one arm, leg, or both.
The last cane overviewed is called the hemiwalker. This cane combines the features of a quad cane and a walker. Its base is much larger than any of the described canes above, thus providing the most patient support. Hemiwalkers also provide an additional amount of lateral support. Patients with more severe hemiplegia or those transitioning from using a walker to a cane will benefit from the use of a hemiwalker.
Lastly, it is important to appropriately size canes. When standing, the arm that is grasping the cane should have a twenty degree bend in the elbow. If there is any confusion, ask your local physical therapist for assistance.
