3-D Printed ‘Magic Arms’ Allow Toddler With Birth Defect to Hug Her Mom

Two-year-old Emma was born with a defect that severely affected her ability to move appendages like her arms. She couldn’t play with blocks, feed herself or even wrap her arms around her parents.
Now, thanks to the versatility and customizable options available from 3-D printing technology, researchers have “printed” an “exoskeleton” that is allowing her to move her arms independently for the first time.

As Emma’s mother, Megan Lavelle, describes in a YouTube video, Emma’s disorder is known as arthrogryposis multiplex congenita.
“When she was born, her legs were up by her ears and her shoulders were internally rotated,” Lavelle, said in the video.
As heartbreaking as this news was for a new mother, she soon found out about a conference in Philadelphia about the Wilmington Robotic Exoskeleton (WREX), presented by doctors at duPont Hospital for Children. The WREX technology, according to Core 77, is not necessarily new, but its functionality for children as small as Emma was previously too heavy.

This is where Tariq Rahman and Whitney Sample thought to bring in 3-D printers. Core 77, a design magazine, has more on the innovation:
Rahman and Sample found that, with the use of 3D printers, they were able to create a lightweight and flexible working prosthetic for Emma, that is customizable with easily replicated broken parts. The custom exoskeletons are printed in ABS plastic and attached to a plastic vest. Because of the ease of manufacturing, the exoskeleton can grow with the child which makes 3D printing especially exciting for those working in pediatric care.

The researchers first had the device attached to a solid structure before they created a mobile vest for Emma. (Image: YouTube screenshot)

Lavelle said the weigh difference from using plastic instead of traditional metal was significant enough that Emma was finally able to begin playing and eating by herself.
“For a child who only weighs 25 pounds, it makes a big difference,” Lavelle said, explaining that she has already outgrown her first vest and is onto her second. “It’s still evolving into this incredible prosthetic that helps her to use her arms.

At one point, Lavelle said Emma called the vest her “magic arms.” Even Emma’s first complete sentence was about the prosthetic. One of the researchers explains in the video that they had taken the device off Emma to make some adjustments and she said “I want that.” At this point, Lavelle teared up and explained this was her daughter’s first sentence.
Watch the clip sharing Emma’s story:
Sample said that with children, the pediatric industry is one that can greatly benefit from 3-D printing devices as they need “custom everything.” Sample called the plastic used by the machine from which they printed Emma’s WREX as “human friendly” given its durability.
Now, 15 children in situations similar to Emma use these prototype exoskeletons, according to Core 77.

Posted on August 7, 2012 at 2:50pmI love this story, but I have to wonder how they are getting away with building a prosthetic without FDA approval? The FDA approval process made the iBOT 4000, a wheelchair that could provide independence for many para- and quadriplegics, too expensive to market effectively, so the project was abandoned in 2009.
Is it because these are “prototypes”? If that is the case, can I “custom build” iBOT wheelchairs and skip the FDA process so they can be built and sold at a reasonable price?

Posted on August 7, 2012 at 11:12amWow…. As happy as I am for her, I can only imagine how happy she is… I hope for only the best for this girl (and others like her…) and hope that some day we can help her genetically to grow strong enough that this is no longer needed…
But for the people responsible for this… You are ALL GREAT…. and should be VERY proud…
Side note: I wonder when Obama will step in and see her moving some wooden blocks and tell her, “You didn’t move that….”
Hopefully people will wake up and realize that Obamacare will nearly destroy this kind of research by taxing it out of existence…
