Assistive Devices

One reason that assistive devices need to be fitted properly is so that they do not cause injury to the user. For example, using axillary crutches too high can cause damage to brachial plexus. Another reason is that improper fit can also lead to improper use which can be a safety risk as a person could not be using the proper body mechanics.  

How to properly fit assistive devices:

Cane: The handle should he at hip height (greater trochanter) or in line with the wrist crease. This makes sure that the shoulders are relaxed and the elbow is flexed about 20-30 degrees.

Axillary crutches: The handles should be in the same position as they are with the cane. The axillary rests should be a few finger widths (about two inches) below the axilla. *The heights of the handles and the height of the crutches themselves can be adjusted

Lofstrand crutches: The armband should be 2/3 of the way up the forearm, and the handle should be positioned the same as the handles in a cane and axillary crutches. 

Rolling walker: The client should be able to stand tall in the walker. The handles should be in line with the wrist crease. The elbows should also be slightly flexed 20-30 degrees. *Since the wheels change the height a little bit, make sure that the walker is level once it is adjusted.

Platform walker: Adjust the height the same as you would the rolling walker, and make sure that the platform for arm support allows the elbow to be flexed at 90 degrees. *Make sure that the proximal elbow is not resting on the platform (prevent nerve compression) and the platform is medial for comfort.
