Its a kickstarter, so I dont know when you would get one.
I think the RRP is set at $599USD, which I think is MUCH less than a Bioness for foot drop. The "Early Bird" is USD $299 (or AUD $458) for base "GO" model.

Im sure they have worked or will work out the details in their "AI". But One of my concerns is that if I stand too long, my knees slowly collapse, so maybe the device would think I am trying to sit, and stop helping me stand.
Every muscle I have mentioned is below the knee but this device is above the knee. All its doing is contracting the three muscles that start at the hip and run down the side of the knee, ending just below the knee (semitendinosus, gracilis and sartorius. By squeezing them it has the effect of shortening them and that makes the knee flex and pulls the lower leg back slightly. You would need a perfectly functional leg action, or minimal loss of function, to be able to use that. If you have trouble walking already, I imagine it would be very difficult to control.
I know it isnt targeted specifically for MS, but as the day goes on, I personally find it harder and harder to lift my lower leg (ie my heel, not jut my toe) off the ground to step over obstacles, which is exactly what this would help with. The testers joke how they feel it kicks their legs in the air. And in the early stages of the day, its lifting action would reduce the fatigue on lifting your leg, as the day progresses.
AND its cheap compared to bioness type devices. I also see an opportunity for future dev specific for MS, or different "AI" programs to target specific deficiencies. eg one leg weaker than the other. Maybe someone like bioness will make similar, and add an ankle stimulant.
If you can't lift your heel, I'd Botox the soleus and the tibialis posterior. If you do that and then sit in a chair, nothing will improve. You would need to go through an intensive range of exercises to lengthen and strengthen all the muscles affected by the tibial nerve. (popletius, gastronemius, flexor digitorum longus, flexor hallicus longus, flexor digitorum brevis, and soleus.) Only an expert (hard to find) would be able to tell if the peroneal nerve is also involved.
Have you tried Botox, or dry needling, with an exercise regime?
Do you think the Ossur FootUp could help you? By providing assistance with dorsiflexion, you might not have to lift your legs so high.CureOrBust wrote: ↑Tue Nov 28, 2023 2:58 pm I know it isnt targeted specifically for MS, but as the day goes on, I personally find it harder and harder to lift my lower leg (ie my heel, not jut my toe) off the ground to step over obstacles, which is exactly what this would help with.

Lifting my leg involves the upper leg and hip muscles muscles. It may help some, but I think the exo-skeleton would help a lot more. As I said, the users talk about how they feel it kicks/picks up their whole leg up.
Although I do like how cheap it is. I found on eBay 1 unit costs $AUD188. Maybe there is a location near me that would allow a test run.
Of course, the thing to remember is, you get what you pay for. Those springs don't look too much heftier than a clothes peg...
I definitely think you should try before you buy. Lifting your whole leg off the ground depends on a range of things. Not least is how strong you are on the standing leg.
Your leg action really starts up in your torso. When your psoas contracts it acts like a pulley, then your iliacus muscles (the hip flexors) need to join in. On your standing leg the same muscles need to stabilise you so you don't wobble and fall over.
After that, a whole range of muscles need to kick in to ensure that the ball of your femur is sitting in it's socket and the knee can both disengage and then lock when it's appropriate.
You definitely need to dorsiflex then strike your heel first when you put your foot down. You then need to roll through the foot so the first joint of your big toe takes the weight (not walk on the outside of your foot). If you can't land the big toe properly, your glutes won't get the appropriate signal to slightly flex your pelvis through internal and external rotation.
If your foot is not clearing the ground and you're hitching your hip to get the leg to swing then your pelvis is probably in a lateral tilt and your hamstrings will feel tight (even if they're not). If you have been compromised for a while, you may also have an anterior tilt and that can also make the hamstrings feel tight.
I don't feel these devices address any of those things. Nonetheless, they may work for you, but I doubt they are appropriate for most people with CNS related muscle stiffness.
Try before you buy.
