Hierarchy of Mobility Skills


The hierarchy of mobility skills is the order that guides the therapist in knowing what area of mobility needs to be addressed in therapy. It starts out with decreased mobility with increased stability and works its way up to increased mobility with decreased stability. One of the reasons why stability is increased in the lower levels of this chart is because the client has a larger base of support; mobility is increased when the client has a smaller base of support. However, I believe that stability vs. mobility isn’t the only reason for the placement of this order. The order is as follows: bed mobility, mat transfer, wheelchair transfer, bed transfer, functional ambulation for ADL, toilet and tub transfer, car transfer, functional ambulation for community mobility, and community mobility and driving

While the order of mobility skills wouldn’t have made sense to me prior to the Biomechanics lectures and practicing transfers in lab, it is now clear to me why this order is important to follow. Not only is stability decreased as you work your way up the hierarchy, but other factors, such as slippery surfaces, small spaces, and/or items that are easier to trip on, makes it vital that the client is mentally and physically ready for the higher levels of mobility.  Without this order, it would be very easy for a therapist to overestimate the client’s ability and possibly increase the risk of a patient getting hurt. It would also pose as a frustrating task for the client since she hasn’t worked her way up to such a higher level task. This could decrease her confidence and motivation and serve as a barrier to completing her occupational goals.  


While we didn’t touch on every level of the hierarchy of mobility in our Biomechanics lab, such as toilet and tub transfers, car transfers, etc., learning how to help a client with bed mobility, wheelchair transfers, and bed transfers helped me understand the level of skill needed for the client in order to be successful in completing these tasks. When helping a client with bed mobility, there was a large base of support and a decreased risk of the client falling or getting injured. In the lab, this put me more at ease because there weren't as many barriers. it became very clear that this was a task that was important for the client to achieve in order to be able to do something like a mat or wheelchair transfer due to stability, posture, physical strength, endurance, cognitive function, etc. It also made me even more aware of the fact that each client has different needs. Some just need to build their strength and endurance in order to do higher level mobility skills, some may need multiple assistive devices, and some people may not have goals that go to the top of the hierarchy of mobility skills chart.


When I worked as a rehab tech, I would assist in bed mobility and transfers. However, I had not learned about the hierarchy of mobility before my Biomechanics class and therefore didn’t think too much about the kind of mobility that was appropriate for the client. It seemed as if it was more common sense and instinctive to the therapist who had been practicing for several years. When I reflect back, the therapists I worked with did follow this model; however, it was not always clear how much the client could achieve due to their condition or motivation. It was always interesting to observe how the therapist would know when to encourage the client to increase the level of their mobility further and when to stay at the same level of mobility. I’m excited to learn more about how to help my future clients in their occupational tasks!

Sizing for Assistive Devices

Sizing for an assistive device is very important. Without an appropriate “fit” for the patient, the assistive device can be a safety hazard and cause the patient to lose their balance and have an increased risk of falling. It can also place too much pressure on certain body parts and cause the patient to have nerve damage. An example of this is having axillary crutches that are too tall for the patient; The increased pressure in the axillary (armpit) area can cause the patient to have damage to their brachial plexus! Listed below are the appropriate ways I would select the correct sizing for a cane, axillary crutches, Lofstrand crutches, a rolling walker, and a platform walker 

• Cane: When trying to select the appropriate size, the patient should be standing and looking straight ahead with their arms relaxed by their sides. When holding the cane, the patient’s elbow should be slightly flexed to about 20 or 30 degrees.  The handles should be in line with the wrist crease with elbows slightly flexed, ulnar styloid, or greater trochanter. In order to adjust the cane, use the pushpin. 
*For a quad cane, you want the wider legs to point away from the patient. If they are not, this can be fixed by rotating the base 180 degrees. 

•Axillary crutches: Like the cane, makes sure the patient is standing tall and looking straight ahead with their arms relaxed. Sometimes the crutches will have heights listed next to each hole. This is helpful to use as an estimate, but it is still important to make sure that their arm pads are placed about 5 cm below the axilla. Like the cane, the handgrips should be in line with the wrist crease, ulnar styloid, or greater trochanter when hands are resting and elbows are slightly flexed. 
         *For Lofstrand crutches, the armband should be positioned 2/3 of the way up the forearm. The handgrips should be pointing forward. 

•Rolling Walker: 
The patient should look straight ahead with arms relaxed. The handgrip should be in line with the wrist creases, ulnar styloid, or greater trochanter. The elbow should be slightly flexed about 20 to 30 degrees when looking for these bony prominences. 

Platform Walker: The platform should be positioned to allow weight-bearing through the forearm when the elbow is bent to 90 degrees. The proximal ulna should be 1 to 2 inches off the platform; The handles of the platform should be positioned slightly medially.


Sizing for these devices should be done with the patient’s shoes on.
