Fitting for Assistive Devices
It is so important for a client to
be properly fitted for assistive devices. First, the correct
fitting can help ensure proper posture and body mechanics
while using the assistive device which will help prevent further issues from
improper posture or body mechanics. Also, a proper fitting can help prevent a
client from falling while using the assistive device.
To fit a client for a cane, when
the client is standing, the handle of the cane should reach either the greater
trochanter, the ulnar styloid process, or the wrist crease of the patient on
the unaffected side. When fitting a client for axillary crutches, the hand
grips are at the same point as the handle of the cane—the greater trochanter, the
ulnar styloid process, or the wrist crease of the patient while he or she is
standing. Additionally, the arm pads should be 5 centimeters below the axilla
so the client does not compress essential blood vessels and nerves in the
axillary region. Lofstrand crutches have the same requirements for the hand
grips as axillary crutches, but it should also be noted that the arm band
should be 2/3 of the way up the forearm. A rolling walker has similar
requirements. The handgrips should line up with the greater trochanter, ulnar
styloid, or wrist crease, and it is important to make sure all legs of the rolling
walker are the same height. A platform walker is slightly different—the surface
of the platform should be at a height that allows the client to flex his or her
elbow to 90 degrees while standing in a relaxed position that still maintains
proper posture and body mechanics. The proximal two inches of the ulna should
be off the platform so that the nerve is not compressed. The handle of the
platform should be angled at a position that is comfortable for the client
which is typically angled just slightly medially. The height of all of these
devices is adjusted by pressing the buttons on the legs of the device, adjusting
the height, and ensuring the device is properly locked after adjustment.
