Linking an amputee with a nerve-connected prosthetic device used to take four days of adjustments. Now it takes about four hours.
Even though modern prostheses are incredible, weighing as little as half a biological limb, 70% of amputees report them feeling heavier. And as a result, it can be harder for someone to accept an artificial limb as part of their body.
In turn, the team developed what it calls a sensory feedback loop. What it really means is that whenever someone moved their prosthesis, researchers automatically sent a certain electrical impulse. And that impulse made the prosthesis feel lighter.
How much lighter? As much as 23% in testing. That number doesn’t just look big; it made a world of difference to how people felt while wearing the prosthesis. Some 36% of subjects reported feeling more confident, and more than half reported that the prosthesis felt more like it was actually part of their body.
