FAQ About the iWalk Crutch

iWalkFREE frequently asked questions

If you’re like most people with lower leg injuries that need to be non-weight bearing, then the answer is most likely YES! But the iWALK 2.0, like other alternatives to conventional crutches, does not work for 100% of cases. Before you order iWALK 2.0 crutch, please review the “Can I Use it?” section of this website.

The short answer is NO, there are no age limits for using the iWALK2.0. But there’s more to it, so continue reading.

We used to suggest an age limit of 12 to 65 for the original iWALK Free generation 1 crutch. But with the new iWALK2.0 and it’s enhanced stability and ease of use, we’ve found that using age as a factor was incorrectly disqualifying too many people who could use the device. So we’ve changed our thinking entirely, and now, we no longer look at age, instead, we’ve adopted ABILITY LIMITS. What does this mean? “Ability Limit” means that as long as you have average strength and average mobility prior to your injury and you fit in with the other parameters covered in the “Can I Use It?” page you are a great candidate for the iWALK2.0. There are plenty of people over the age of 65 that have average strength and average mobility and would do great on the device. There are also people under the age of 65 that don’t have average strength and mobility that shouldn’t use the device. It all depends on who the person is and what their abilities are.

A good rule of thumb is if you can ascend and descend stairs without requiring the hand rail for balance or support, then you can iWALK.

Possibly. We wish we could give you a better answer, however, with the constantly changing climate of health insurance, there is no simple answer. Coverage for traditional crutch alternatives depends on your insurance carrier, your physician, where you live and other factors over which we have no control. Check with your physician and insurance company to find out if the device is covered and what percentage or amount they will pay. You can also take a more proactive approach. Administering your own claim is not difficult, and we have had many customers who choose this route and are successful. To make things easier, we’ve provided step by step instructions which you can find by clicking here (link to the new insurance page). Typically iWALKFree will be classified under the DME (Durable Medical Equipment) portion of your insurance policy, however, there are many exceptions. When making inquiries to your physician or insurance company, you will want to provide them with our product code, which is HCPCS E0118.

For more information, please visit the Insurance page of our website, or check with your local retailer or distributor.

Yes! In fact, we made the calf strap extra long just for this purpose. But there’s few things you should know.

First and foremost, check with your physician. That done, the most obvious limitation is that the cast has to be restricted to the lower leg, below the knee (you have to be able to bend your knee 90 degrees to use the iWALK 2.0 crutch).

Ideally, your cast will not contact the knee platform (but it’s ok if it does… we’ll cover that in a minute). So here’s a hint – sometimes your physician will make your cast a little shorter if they know you intend to use the iWALK 2.0. The knee platform is 12 inches long, so if your cast can be more than 12” from the front of your thigh (with your leg bent at 90 degrees), you’re home free. To find this spot, kneel on a chair or stool so that your leg is bent 90 degrees. Measure back 12 inches from the front of your thigh, going back towards your foot. If the cast is below this point, then you can wear iWALK 2.0 without any accommodations.

If any part of the cast is going to rest on the knee platform, you’ll want to measure the diameter of your casted calf at the location where the calf strap will go around your calf. To find this spot, kneel on a chair or stool so that your leg is bent 90 degrees. Measure back 10 inches from the front of your thigh, going back towards your foot. If the casted circumference at that point is greater than 22 ½”, then you may still be able to use iWALK 2.0, but you’ll need to contact us before you place your order so we can determine if iWALK 2.0 will work for you.

You’re also going to want to add an additional pad or spacer to level your leg on the knee platform. This is necessary because the cast will slightly elevate the back of your leg, plus there will be a “step” where the cast ends and the uncasted part of your leg begins. To take up this space, we can supply additional padding (call us), but we’ve found that a folded hand towel makes an ideal spacer. Try it first and see how it works for you. Put the spacer directly onto the knee platform so that it contacts the uncasted part of your leg and voila…you’ve customized your iWALK 2.0 for your casted leg.

No. There is a common misconception that you are kneel on your knee (maybe that’s why the word is “knee-l”) when using iWALK 2.0, but you don’t. When you use the iWALK 2.0, only your shin comes in contact with the knee platform (perhaps we should have called it the shin platform?) When the knee is bent 90 degrees, the patellar region is not in contact with the platform and thus does not bear any direct weight when using the iWALK 2.0.

Yes. Navigating stairs on conventional crutches is dangerous and strenuous, but taking stairs is one thing that you can do with your iWALK 2.0 crutch that you can’t do with a knee scooter or conventional crutches.

Nothing lasts forever, but your iWALKFree will last a long, long time…probably much longer than the time you will need to recover. The most common things to wear out are the knee platform pad, the thigh saddle pads or the rubber foot tread. But fear not. Replacements for all of the parts of the iWALK 2.0 are available from us.

Yes! But if the height difference is more than 1/2 inch, you’ll want to adjust the height of the knee platform and the thigh straps. Luckily we’ve thought of this, so it’s quick and easy to make height adjustments.

Yes. The special padding used on your iWALK 2.0 is hypoallergenic and FDA and CE approved to come in contact with your skin.

Yes, but you’ll need ample space in front of your chair for the beam below your knee to extend. If this is an issue, we’ve designed iWALK 2.0 to be easy and quick to put on and take off.

Most often the answer is yes. If the broken bone is in your foot or ankle, almost certainly you can use iWALK 2.0. If in your fibula, then it’s also very likely. If you have a broken tibia, then you probably cannot use iWALK 2.0 but we’ve seen many instances where this was still possible. In all cases where there are fractures, you need to check with your physician before using iWALK 2.0.

A small minority of people need augmentation of the padding under the area just below the knee cap. You can accomplish this a couple of ways. First, you can simply take a wash cloth or small hand towel, fold it over a few times and use that on top of the existing padding. You can also purchase a second pad and stack it directly on top of the existing pad. The new pads have peel and stick application, so it is a very easy fix. If you are in the US you can purchase a new pad here.

Answer: Absolutely- in fact, the iWALK2.0 is an everyday item for many BK amputees who use it in common situations when they don’t want to don their prosthetic leg. Examples are showering, short trips, at the gym, beach etc. iWALK2.0 is commonly used as a prosthetic training device for new amputees who are learning to walk on a prosthetic or for those who cannot yet tolerate a prosthetic limb. Also, if your prosthetic limb isn’t available, for example, if it’s getting repaired, the iWALK2.0 is your best substitute.

A commonly overlooked feature of the iWALK2.0 is that the mounts for the calf strap are free to slide forward and back on the “rails” which are integral to the side of the knee platform. This was done so that the user could position the strap in different locations to accommodate different conditions, casts, boots, etc. For amputees, this feature is key as it allows forward placement of the strap to accommodate residual limbs as short as four inches.

To maximize stiffness, the front face of the Knee Platform, which spans between the two vertical aluminum tubes, was designed to be straight across the front of the knee platform. We consulted well established anthropomorphical databases to make certain there was clearance for the knee, but in rare circumstances the knee does contact the upper edge of this section, resulting in discomfort. The best solution is to remove some of this material, as it really isn’t needed – the Knee Platform is plenty stiff. In fact, at the time of the writing of this FAQ, we are implementing a running change to do just that.

So if the edge of the knee platform (located in between the two vertical alloy tubes) is straight across, you can simply remove some material by using a file, grinder, dremel, etc. We agree that this isn’t entirely elegant, but it does solve the problem, and it won’t hurt your crutch at all. Just remove a little bit of the material, starting at the center, until you have enough clearance that your knee no longer makes contact. It’s easy, and shouldn’t take more than a couple minutes to accomplish. Here is a picture to demonstrate this.

We are sorry to impose on you to make this modification, but we want to keep you comfortably iWALKing throughout your non-weight bearing period.

Another solution is increase the thickness of the knee platform pad (the one that you kneel on). This raises your leg and may provide the additional clearance you need. All you have to do is stack the new pad on top of the old one. The pad comes with a peel and stick adhesive, so installation is quick and easy. https://store.iwalk-free.com/Spare-Part–Knee-Platform-Pad-Kit_p_21.html

If the area just below the kneecap (tibial tuberocity) is sore, try giving it a couple days. Most people who report initial discomfort find that it resolves itself within a day or two. If that doesn’t work we’ve found that a second pad, stacked on top of the existing pad, solves the problem. You can purchase the extra pad directly through our website here. The pad has a peel and stick application, so doubling them up is quick and easy. So why don’t we make the pads thicker? We could, but the connection between your leg and the crutch is crucial– since your human foot is no longer in contact with the ground, you gain feel and control from your shin, so the less padding, the better. We have found that our 13mm pad is the best compromise for the vast majority of people, however, one size fits all is virtually impossible, so fortunately purchasing a supplemental pad is a quick, easy, inexpensive fix. If you prefer, you can fold up a common hand towel and achieve the same thing, but it won’t be as professional looking.

The rubber that we use in our treads is about the same durometer as the tread on a tennis shoe, and has equivalent grip. That said, unlike a human foot, the iWALK foot does not have either fine motor control or the ability to flex at the ankle. As such, the surface area presented by our crutch will not always be equivalent to the human foot, and since traction and surface area are related, an iWALK foot, despite similar material, can have less traction than a human foot. Hard, slippery surfaces such as tile, polished hard wood, marble, etc., especially when wet, are slip and fall hazards regardless of the footwear, including iWALK2.0 treads. These surfaces are also very slippery to conventional crutch tips, which have even less surface area and are controlled by arms, not legs.

So can an iWALK2.0 slip on hard, slippery surfaces? Yes, of course. But so can a standard shoe or, and especially, a conventional crutch tip. Just as with regular shoes, caution must be exercised on any slippery surface, especially when wet. Caution and good judgment must be your guide in such situations.

One tip we can provide is that if the iWALK2.0 is brand new, the user can proactively scuff up the bottom of the treads. This typically happens rapidly in normal use. As the tread leaves the mold, the surface can be quite smooth, and just like sanding a piece of wood to make paint adhere, a bit of surface roughness assists in traction for the iWALK2.0 tread (and any tread for that matter). So if your iWALK2.0 feels slippery on any surface, try scuffing up the bottom of the treads and carefully try it again to see if things improve.

27″ at the very top of your thigh is the largest that we would recommend for a couple reasons. First, and most important, going beyond the 27″ maximum can make it more difficult to tighten the straps as much as is necessary for proper function. Second, the quick release buckles on the straps might not function optimally because you may not be able to loosen the straps enough to allow easy engagement and disengagement. We have seen people use the iWALK2.0 with up to a 29″ thigh, but you need to be aware and accepting of the possible functional compromises.

The treads are made from material which has about the same traction as a tennis shoe in wet or dry conditions. Because you cannot articulate your knee or ankle in the iWALK, surface area on various terrains can be reduced, so some caution should be exercised. One thing to remember is that the traction and control using the iWALK2.0 will be substantially better than conventional crutches. In the event of an off balance incident, you will have much better recovery potential with a crutch that utilizes your leg than with conventional crutches which use your arms.

The solution is to replace the padding, which is easy and inexpensive. The average person uses the iWALK2.0 for 3-6 weeks, and the padding will typically last longer than this, but not forever. Also, there is a small percentage of the population who have a protrusion in the tibia just below the knee, and for these people the area of the pad just behind the knee can compress rather quickly. In these rare instances, the answer is to get a second pad and simply stack it on top of the first. The replacement pads come with peel and stick adhesive, so they are easy to install. You can find the knee pads here.

One thing to note- the connection between the user and the crutch is essential for feel and control. If the crutch had no padding, it would function even better, but of course, it would be very uncomfortable. Too much padding would mute the interface between the crutch and user, and while it improves comfort, it reduces feel and control. We worked hard to find the optimum compromise between comfort and control, which is why our padding is not thicker. But for those rare few, the padding isn’t enough, so adding supplemental padding is necessary.

We’ve used industry standard studies to determine the sizing range for the iWALK2.0.  That said, humans come in all sizes and shapes, so there will always be rare instances where the iWALK won’t fit people even though they fall inside our size range.

Leg length is what matters for sizing the iWALK crutch.  But nobody knows their leg lengths, so we use height as a starting point.  The industry studies we use cover 95% of the human population, so what that means is that at the far extents of our size range (4’10” and 6’6”), there’s a 95% chance the iWALK will fit.  As you move further from the minimum / maximum range, the greater the chance that the iWALK will fit.  In fact, we know that the iWALK will fit people that are shorter or taller than our minimum/maximum requirements.

We provide a leg length chart that details the requirements for both upper and lower leg length.  This is the only way to be 100% certain that the iWALK2.0 will fit.
