> Scientists have helped a partially paralyzed man walk the length
>of three football fields by implanting electrodes in his spine.
>
> While it doesn't quite make Arizona quadriplegic Ken Paulson
>the bionic man, it does allow him to walk farther, faster and with
>less effort.
>
> Researchers say that if they can prove the therapy works on a
>large scale, it could help perhaps one-third of the country's
>230,000 spinal cord patients -- those who still have some feeling in
>their legs and some control of their leg muscles.
>
> ``This will not take the wheelchair away from me completely,
>but it has given me a whole new perspective -- independence,'' said
>Paulson, 45, who was injured in a 1997 car accident. ``You put me in
>the Back Forty of a Wal-Mart parking lot now and I can probably walk
>to the door.''
>
> Researchers stress that while Paulson had positive results,
>other people may not. Large-scale studies are needed, they said.
>Even after more than a year of physical therapy, Paulson cannot
>climb stairs or walk backward.
>
> Researchers from Arizona State University and Good Samaritan
>Regional Medical Center in Phoenix reported Paulson's recovery in
>the journal Spinal Cord.
>
> The experimental procedure, which is not yet available to other
>patients, involves having patients walk on treadmills while their
>weight is supported by a harness. This retrains the legs on how to
>walk.
>
> Later, doctors implant electrodes on the spinal cord to
>stimulate the neuro circuit, which coordinates leg muscles. Although
>both have been tried separately in the past, this is the first time
>they have been used in combination.
>
> ``The results were way beyond my expectation,'' said Jiping He,
>a professor of bioengineering at Arizona State, who was involved in
>the research. ``I thought we would see some improvements, that he
>could make a bathroom trip or get into the shower stall, but now he
>can walk across the street.''
>
> After treadmill therapy alone, Paulson could walk 10 feet in
>two minutes, He said. But after the electrodes were implanted,
>Paulson could walk more than 100 feet in the same two minutes, and
>has worked up to walking 1,000 feet before getting tired. Doctors
>hope he'll be able to switch from a walker to a cane for balance.
>
> Jessica Agramonte, senior research scientist and gait
>specialist at Stanford University Medical School, said that while
>the results are promising, ``One must be very cautious in
>interpreting a single case study, particularly for patients with
>incomplete spinal injury -- they can have a very individual course
>of recovery.''
>
> Others called it a move in the right direction.
>
> ``The research should definitely excite some interest. This
>could have some help for patients with multiple sclerosis and those
>with incomplete spinal cord injuries,'' said Dr. Inder Perkash,
>director of the spinal cord injury program at Palo Alto Veterans
>Affairs Health Care System.
>
> But Perkash noted that patients must be highly motivated and
>willing to exercise frequently and push their limits.
>
> ``It's a lot of work,'' Perkash cautioned. ``If a patient does
>not exercise and maintain his muscle tone, he will regress.''
>
> Although any developments in the area of spinal cord research
>are exciting, some patient advocates said, the field still has a far
>way to go.
>
> ``Being able to walk 1,000 feet is great, but that's not going
>to get you a job,'' said Marcie Roth, executive director of the
>National Spinal Cord Injury Association. ``It's not going to address
>a lot of the critical challenges that people with spinal cord
>injuries face every day.''
