WRHW - here is the update.
First, let me say, the device is great but, it does not produce miracles!
I wear the WalkAide everyday - it has become part of the routine (sort of like brushing your teeth every morning!). Once I get it on and get the impulse regulated (easy, easy), I kind of forget about it. ---Until I start off on the wrong foot. The device is built around a tilt sensor, so if I step forward with my bad leg it gets kind of confused and I do a "stutter step". I have to move forward with my right leg (the left is tilted back) and everything is fine. Turning is another issue - I have to remember to step forward and turn with the right leg. So far, going up stairs is still a challenge. It will lift your foot, but you still have to lift the leg which is a weakness of mine. No different than before the WalkAide.
The ankle seems to be getting a little more flexion on its own. I am able to walk without the WalkAide and strike with the heel first instead of being flat-footed. (for very short distances) My theory is that the WalkAide is now allowing my leg to use the correct muscles to walk - some of the muscles have not been used 100% for a long time; therefore, they are naturally weak. With continued use, it seems to me that the leg will become stronger.
In comparison to the Bioness product, I am still happy with my choice. The only hesitation would be that the Bioness video shows a patient walking up and down three or four stairs without a problem. (is this a true picture?) As mentioned above, stairs are still an ongoing challenge. But, I like the WalkAide because it is smaller, more compact than the Bioness.
It has been snowy and cold for the past few weeks, so have not ventured onto a dirt path as of yet. It will be interesting to see how I do walking on an uneven surface.
Insurance would not cover, so I went on an 18-month no interest pay plan.
If you have any other questions, please let me know. You can PM if you like.
