Let’s salute the great cyborgs of our time. RoboCop, Darth Vader, Inspector Gadget, and now the Shadenator 9000, the latest development in Shade technology. But first, this sci-fi tale needs some backstory.
As you are likely aware, Shade’s last two strokes three years ago (17 y.o) paralyzed his left side, wiping out any progress he’d made since his first stroke when he was twelve. (We’d just got him walking again, damn it!) Because his left arm and hand are so weak, they have tightened up, contracting the arm like an L and keeping his fist closed. This caused a vicious cycle. Because tasks are so hard to complete with his left arm and hand, he uses his right, and thus his lefty gets weaker and tighter. We were worried he might lose all use of it.
Then Aitza told me about a friend who started using a robotic device after his stroke and got full use of his arm again. And that’s how we discovered Myomo. It’s not a cult, I swear, though I may be an apostle after Shade and I went to try one out last week with Myomo representative Heather Ward.
Myomo, a contraction of My Own Motion, produces the MyoPro, a powered upper-extremity orthosis that’s straight out of a fanboy’s wet dream. The robotic brace straps on the recipient’s arm from shoulder to fingers. Soft bracelets embedded with sensors are worn on the upper arm and forearm. Like an EMG, they pick up myoelectric signals from the brain that trigger the muscles to contract and move the limb. These signals simultaneously trigger the robot’s motors to move the orthotic in accordance with the desired
action. So if Shade wants to extend his arm, that signal is mimicked by the device, which will extend, adding strength to his own arm and allowing him to stretch it out.
Even if the wearer cannot naturally move part of the arm, as long as the brain signal is there, it can be boosted to a level where the orthotic will move it for him/her. For example, Shade cannot move his wrist up and down no matter how much he mentally strains to do so. However, on her laptop, Heather boosted his EMG signal and the robot moved the wrist up and down. Brain power.
What this means is when Shade straps on his assistive MyoPro robo-brace, he should be able to perform functions with that arm that he’s been unable to do since his second stroke. Things like putting dishes on a high shelf, grabbing a water bottle off a table or petting his precious cat Cheetah. And because he’ll be using his arm more, it will strengthen and loosen up and he may be able to start using his arm more without the device. Plus, I’m shooting for the upgraded version with the laser cannons on it. Pyew, pyew!
What’s more, we’re looking at another device that may help Shade get back on his feet. We’re going to have a fundraiser soon to help with the expense of this device. I’ll tell you about the other device and the upcoming fundraiser in the next blog. Once we get these devices the Shadenator 9000 will be launched.
