Now we will cover how to tailor the fit of your iWALKFree. Adjustments are quick and easy and require no tools.
Your safety is our first concern, so before using your
iWALKFree, please do the following:
As a reminder, before trying the iWALKFree for the first time, make sure that the device is right for you.
Sit in a chair with your knee bent at 90 degrees. Using your uninjured leg with shoe on, measure the distance from the ground (just behind your heel) to the bottom of your thigh (back of your knee – where your thigh meets your calf ). This measurement will be the initial height of the iWALKFree Knee platform (Figure 1-1). Note – you might fine tune the height after your first few times walking on the iWALKFree.
After you have completed your adjustment, make sure that the locking pin is securely engaged in the holes in the back of the beam and that the cam latch is closed. This will be the starting point for the Knee platform height adjustment.
In the following set of instructions you will be strapping the iWALKFree to your injured leg and adjusting the two thigh straps and the platform strap. Before proceeding, remember to support yourself by keeping as much of your weight as possible on your uninjured leg and using a table, sofa, etc. for balance.
Remove the three adjustment straps from their buckles (platform strap and two thigh straps). Fig 2.1
Slide the platform strap and buckle as far back as possible on the knee platform. With most of you weight being supported by your uninjured leg (this is important!), place the shin of your injured leg onto the knee platform pad, with your knee as far forward (toward the beam) as possible. Slip the adjustment strap into the buckle and snug the strap around your calf. If wearing a cast, you might need to put the strap over your cast, or you can slide the strap and buckle forward on the kKnee platform until the strap assembly is clear of your cast. Fig 2.2
Make sure that the foam padding on the strap is centered on your calf (Fig 2.3.1-3). It’s essential that the foam pad does not interfere with the buckle. If the pad touches the buckle, you will not be able to fully tighten the strap and stability will be significantly compromised.. If the padding is not centered or touches the buckle, remove the crutch and slide the foam to the correct postion. If you have difficulty in moving the foam, see our Tips and Tricks section.
This also applies to the upper and lower thigh straps.
The lower thigh strap serves two purposes A) It holds your lower thigh firmly against the beam B) It holds the front of your calf firmly against the knee platform and prevents your knee from lifting). To correctly fit the lower thigh strap:
Do a final tightening of all three straps. Get them as snug as you can without discomfort. Tip – hold the buckle against your leg with one hand while you pull firmly on the strap with the other.

Now that you’ve successfully strapped the iWALKFree to your leg, we can do a quick test to see if you’ve properly adjusted the knee platform height.
While standing with most of your weight on your uninjured leg, you should be able to swing the iWALKFree front to back without the rubber tread (foot) hitting the ground. Note that it should come very close to the ground without actually making contact. Figures 6.1 and 6.2 below show correct and incorrect knee platform height. Remember to use a handrail or similar for stability until you get used to the device.

Fig 6.2 Correct knee platform height – leg can freely swing though, tread just above ground at mid stride
