Bradley
Tolleson, a 13-month-old Marion boy, is learning to
use a bionic hand in place of his left one, which
did not form in the womb.
Bradley’s parents, Laura and Jeremy Tolleson of
Marion, said their son’s malformation was discovered
during an ultrasound.
The test showed that fingers on one of the
boy’s hands didn’t develop due to amniotic band
syndrome, a condition that causes the amniotic sac
to form around an appendage and cut off the blood
supply so it cannot fully develop.
“Once we did the four-dimensional ultrasound,
we knew for sure,” Jeremy Tolleson said, but Laura
Tolleson added, “we were always hopeful they were
wrong. We hoped for a miracle.”
They eventually got their miracle.

Bradley Tolleson, grandson of Larry
Sharpe, is one of only a few children
his age in this country who has this
bionic prosthesis. His parents use a
large, inflatable exercise ball, games
and songs as part of his strengthening
therapies for teaching him how to use
his prosthetic arm.

“The first thing
that went to my mind when I saw this was ‘bionics,’”
Tolleson said, who began investigating prosthetics
on the internet.
He saw a television segment that featured a boy
using an arm to perform everyday activities. The
company that produced the arm was Pediatric
Prosthetics.
Tolleson contacted the company that evening and
received a message the next morning.
When Jeremy described the condition to
Prosthetics representatives, they encouraged him to
e-mail photos of the arm.
“They really wanted him to be walking (before
receiving the limb), so the weight wouldn’t throw
off his balance,” Laura Tolleson said.
In March of this year, a year and half after
placing their order for Bradley’s arm, the Tollesons
traveled to Prosthetics in Houston, Texas, for his
fitting.
The arm is a hard plastic prosthesis with a
skin-colored rubber cover. It is just a few inches
longer than Bradley’s own arms, and the hand has
five individual, moveable fingers the same size as a
toddler’s.
The outfitters showed the couple how to help
Bradley perform the physical therapy to help him
adjust to the arm.
“We do ‘Deep and Wide,’ ‘Patty Cake,’
‘Itsy-Bitsy Spider, anything to get him to raise his
hands,” Laura Tolleson said.
They do “Superman,” too, to get him to hold out
his arms, and all the exercises strengthen the
muscles he’ll use to operate the arm and hand.
Bradley’s bionic hand can pinch his thumb
together with his index and middle fingers.
Jeremy Tolleson explained the current pressure
in his fingers is only at “cookie crusher,”
strength.
Laura Tolleson said Bradley is constantly
opening and closing his hand, triggering electrodes
just under his elbow by the muscle movement which
would naturally control his grip.
“The hand works off of the electricity in the
muscles traveling from the brain waves,” Jeremy
Tolleson said. But because of his age, Bradley
doesn’t yet understand how to voluntarily open and
close his hand.
“To work this muscle movement, they encouraged
us to carry a small object all the time,” Laura
Tolleson said. “So when he opens his hand, we can
put something in it to let him know he can grab
something.”
As Bradley learns to master his grip, he’ll
receive an arm model that will allow him to control
the amount of pressure he uses when holding objects,
and he’ll be refitted for a new arm each year.
Jeremy Tolleson said friends and family are
amazed the technology is so advanced. He added that
Bradley is among only five or six children in the
country his age who have this arm.
He said he’s very excited about the promise
bionics holds.
“In the future, we really don’t know what can
happen. Right now, he can move just three fingers,
but in the future he could be using all five.”
Despite their marvel over the technology, the
Tollesons said they consider their son complete and
capable.
“This is more or less a tool to give him a more
normal life,” Jeremy Tolleson said.
Laura Tolleson added, “He’s developed fine up
till now, and he can do things without the arm, but
we wanted him to have this so he can do more. And
later, if he wants, he can go without it.”
