Hypershell Exoskeleton part 2

The exoskeleton helps with the weakness, but it does not help with the awkwardness. I am still a huge fall risk. Maybe that will improve a bit, with practice, but for now I need something to steady myself.

I have this red rollator walker I use every day around the house, and for expeditions to places I can’t use a wheelchair. I like it because it is super lightweight and very stable. So I started with that. The problem is, that when the exoskeleton improves my posture, the red rollator is too low. And it is at its highest extension. There is a part that can make it taller, but back when I last tried to order that part, the pandemic supply chain snafus made it impossible to get. I need to try again.

I also have the Up Walker. This is a hand-me-down from a neighbor. It’s a rollator that supports under the elbows, specifically intended to make the user walk upright. It is a good position, but this particular unit feels rickety and unstable. I think it’s because I am at the very tallest adjustment point and this thing is old and beat up and was probably always flimsy. We improved the stability by tying a rope around it to brace it at the top, but it’s still iffy.

So I decided to try some arm crutches. The first pair I tried was awful, I felt like they pitched me forward. I sent them back to Amazon and got a different pair that let me bend my elbows. These felt great but I almost fell. I am going to keep them and try again if I get better at this. And perhaps wear a bicycle helmet.

I am going to go down to the local DME, one day soon, and test drive walkers. Maybe they have a larger and more solid version of the Up Walker.

I am also experimenting with AFOs for my dragging left foot. The best one I have found so far, doesn’t fit in my shoe. I am continuing to try other AFOs, but I also intend to look at some different shoes.

It’s easy to just give up when something fails to be a magic bullet. But adaptive devices are never perfect right out of the box. You have to work on it and figure out how to fix your problems. And I enjoy figuring it out, finding the right combination of things. I used to do this with my motorcycles. This is just a new focus for my urge to tinker with things and try out new gadgets. It is good to have a hobby!

The next gadget after the nerve zapper, is the Hypershell Exoskeleton. This is something completely different. There is a frame that belts around the waist, and metal struts connect it to cuffs that buckle above each knee. There is a little electric motor on each hip, powered by a battery in the shape of a fanny pack. It is controlled by a phone app. It detects what the wearer is trying to do, and helps them.

The manufacturer insists that it is not a medical device. They market it for recreational use. They suggest that if a couple enjoys hiking but one is not strong enough to keep up with the other, this can even the score so they can enjoy hiking together. Or if you just want more range, or to carry more stuff. Not a medical device! But there are end users talking it up online, for MS or Parkinson’s. I would guess there are two reasons the manufacturer disclaims medical use cases. One: Companies aren’t legally allowed to make medical claims without doing peer reviewed studies and a shitload of paperwork. Two: Liability blah blah blah.

Since it is not a medical device, it’s much cheaper. Not dirt cheap, but at under a grand it is a pricey toy, instead of something people mortgage their house for because the insurance denied it. And there are no medical gatekeepers. But I still think caution is in order. If I were more fragile it could get pretty risky.

So, how is it?

I don’t feel like a marionette or anything. The software is really good and my movements feel quite natural. Things are just easier to do. I notice I hold myself more upright when walking with it. It doesn’t make any noise. Great that I can wear it outside my clothes, and there are no electric shocks.

The fit could be better. I am at least six inches taller than an average woman and most of that extra height is in my femurs. If the exoskeleton were longer, it would have more leverage on my body. I am also a bit over the official max weight. It isn’t uncomfortably tight, but there isn’t any extra room either.

It has a bunch of modes for walking and running and stair climbing and stair descending. I wish it had a mode for standing around but it doesn’t, so standing around is still hard. It also doesn’t do anything for foot drop.

I like it and I am trying to walk a little with it each day. More about that later.

Happy Wednesday!

I'm taking search offline sometime today to upgrade the server to a new instance type. It should be down for a day or so -- sorry for the inconvenience. If you're curious, the existing search machine is over 10 years old and was starting to accumulate a decade of cruft...!

Also, apparently these older machines cost more than twice what the newer ones cost, on top of being slower. Trying to save a bit of maintenance and cost, and hopefully a Wednesday is okay!

Edited: The other cool thing is that this also means that the search index will be effectively realtime afterwards... no more waiting a few minutes for the indexer to catch new content.

Hi all

The next book will be 'Death in the Andamans' by M M Kaye, which I am hosting.

I plan to start on May 19th (due to commitments earlier in the month). I'll post every Tuesday.

There are 24 chapters, so I'll do two at a time.

See you then!

So that's all over, bar the shouting? No! Three chapters is plenty of space for more trouble.

Lucy comes around at the opening of chapter 20 Read more... )

I feel that we can all agree with Phyl's assessment of Godfrey as a "stinking twerp".

Chapter 21, and there's nobody at the Castello. Read more... )

Chapter 22 takes the action all the way to the end. Read more... )

And that's the end! Thank you all for reading and commenting along. Comments are open for your thoughts on the last three chapters and/or the book as a whole. [personal profile] wychwood, what are we reading next?
