The iWALK 2.0 is a temporary lower leg prosthetic that replaces conventional crutches and knee scooters. It allows hands-free and pain-free mobility for your patients. Patients prefer the iWALK over other mobility devices—also, people using the iWALKhave been proven to heal faster than those using conventional crutches. The iWALK works for most people, but it’s not for everyone. So, as a fitter, your first duty is to predetermine if the iWALK is suitable for your patient. This is one of the most important things you can do.
The Two Basic Physical Ability Test
Before the injury, the patient could fluidly walk up and down a flight of stairs at a normal walking pace without using the handrails.
Can the patient balance on their good foot for at least 30 seconds?
So, if the patient could pass both tests, then they have the physical ability to succeed on iWALK 2.0. But If they can’t, then they are probably better off on a different mobility device.
Additional Physical Requirments
- Is Non injured leg fully functional?
- Injury below the knee?
- Can the injured leg bend 90 degrees?
- Is the patient not significantly overweight?
If your patient answers no to any of these, then the iWALK is not suitable for them.
The second elements are motivation and a positive attitude. These are essential elements to success with the iWALK. Some people learn faster than others. Therefore, you should notice that your patient is motivated to keep trying or committed to succeeding.
Prerequisites Capacities And Limitations
To ensure the safety and success of your patient, you must stay within the capacities and adjustment range of the iWALK.
iWALK Height Limitations
iWALK Short End Height Limitations: 4’10” to 5’2” and iWALK Tall End Height Limitations: 6’2” to 6’6”
so there is a 95% chance the iWALK will fit you.
iWALK Weight Limitations
The weight limit for iWALK is 275 pounds maximum.
Using age as a criterion is way too broad because the mobility of seniors varies significantly from person to person. So with the elderly they use the same criteria as the non-elderly. So no matter your age, the requirements are the same.
Significantly Overweight Patients
The iWALK uses the upper thigh to stabilize the device. However, a high body mass index (BMI) results in more unintended movement of the device. This reduces stability and control, which makes it harder for the user to adapt.
If the patient also has obesity or neuropathy, success with the iWALK is unlikely.
Below Knee Amputees
Must have at least 4inches of residual limb behind the back of the knee. All these conditions present unique challenges and must be assessed on a case-by-case basis.
Key Concept Of Fitting
Why is proper fitting so important?
People think about how to walk, and they do it because they have developed the muscle memory for walking over their entire lifetime. The iWALK crutch becomes your patient’s lower leg, so the closer you come to mimicking their normal-like geometry, the more they can recruit their pre-existing muscle memory for walking.
The iWALK crutch becomes your patient’s lower leg. So, the closer you come to mimicking their normal geometry, the more they can recruit their pre-existing muscle memory for walking. There must be a secure connection between the patient’s leg and the iWALK to eliminate unintentional movement of the crutch. With only minor adaptations, the patients use the same muscle memory they used their whole life.
The Three Key Objective
- Angled right
Height refers to the two height adjustments of the iWALK. The lower height adjustment is below the knee platform. The upper height adjustment is above the knee platform.
Tight means that the straps are clenched fully tight. Tight straps eliminate all unintentional movement of the crutches, which is essential for stability and control. When properly tightened, it’s nearly impossible to slip a finger between the strap and the patient’s leg.
Angled Right refers to the vertical angle of the crutches. The proper vertical alignment will place the iWALK foot where the patient’s human foot would normally be.
Preparation For Fitting Patient And Environment
- Remove everything from patients’ pockets Make sure they are not carrying anything like a purse or a backpack.
- Find the top of the leg.
- The area should be suitable for walking, like a hard level surface that allows the patient to walk at least ten steps in a straight line without any obstacles.
- The patient should maintain an upright, errect posture during the entire fitting process.
- The patient must be mentally and emotionally prepared and motivated.
