Byron Marsolais was born in Adams County, Iowa.
Marsolais graduated from the University of Iowa,
where he went on to obtain his medical degree
in 1963. He also holds a Master's degree and Ph.
D in Mechanics and Hydraulics, which he completed
at the University of Iowa in 1969.
Since 1970, Marsolais has held multiple professorships
at Case Western Reserve University and School
of Medicine. He is currently Adjunct Professor
of Biomedical Engineering and Professor of Orthopaedics.
He is an investigator with the Cleveland FES Center
and the Louis Stokes Cleveland VA Center of Excellence
on FES Center as well as the Director of the Division
of Rehabilitation in the Department of Orthopaedics
at CWRU School of Medicine.
A prolific author, Marsolais is also an editorial
reviewer for several professional journals. He
is also President of the Orthopedic Rehabilitation
Association for 2000-2001.
Marsolais is married and has one child.

At what level of injury could a person get the
ability to stand and transfer with a FES system?
How many centers are actually doing this?
qualify for the Cleveland FES Center's multicenter
study of the implanted standing transfer system,
an individual must have a spinal cord injury at
the C6 (cervical level) to T12 (thoracic level).
There are many other qualifying factors as well.
Detailed information is available from the Projects
area of our web
site. Currently, 3 centers have enrolled research
participants in this research program. This trial
is funded with support from the Department of
Veterans Affairs Rehabilitation Research and Development
Service, the Food and Drug Administration Office
of Orphan Product Development and the National
Institutes of Health.
I was so amazed watching the program on how FES
works. I work in a geriatic population here in
Omaha, NE. Is there a particular age group that
you consider for this procedure? What are the
indications and contraindications? There is no
doubt that a lot of people can benefit from this
breakthrough. Where can I get more information
regarding the procedure?
there is no real limit on age although most of
our research participants with spinal cord injury
are young to middle-aged adults. Some research
groups are studying the use of permanent implants
in growing children with paralysis. Studies in
geriatric individuals at our center have been
directed toward stroke survivors and use less
extensive implanted components. Sufficient cognitive
ability to understand the use of the system is
an important factor. Detailed information on Cleveland
FES Center research is available from the Projects
area of our web
Is there a difference between "external functional
stimulation" and the FES system discussed on the
though the outcomes might be similar and each
has its own advantages and disadvantages. Most
would consider "external functional stimulation"
as systems working with electrodes that apply
to the skin like a bandaid. In this case, the
cost is relatively low and the system is non-invasive.
The user puts on the entire system each time he
or she uses it. However, it can be difficult to
place the electrodes correctly, and sometimes
the stimulation activates the pain nerves near
the skin's surface, making the usage uncomfortable.
The internal system highlighted in the program
for standing and transfer assistance, stepping
or hand grasp, requires surgery to implant. Putting
the system on each day only requires placement
of an antenna coil over the implant stimulator
receiver and the system does not typically activate
pain fibers. Users indicate that these are advantages
of the internal system.
I think your system is very interesting and I
see how it could benefit many people. I was curious
exactly how and what the input system is made
of and how it works. I have researched systems
that directly connect, but nothing like this.
As a professional artist I would also like to
volunteer if you need any help in art and graphics
department for your project for your beneficial
system consists of an external computer/controller
that attaches to an antenna coil. The antenna
coil is placed over an implanted stimulator receiver
that generates the actual stimulation charge.
Lead wires carry the charge underneath the skin
to implanted electrodes that are connected to
the muscle to be activated. The electrode delivers
the charge to the nerve, causing a muscle contraction
and producing the actual movement. Depending on
which type of FES system he or she uses, the user
tells the computer/controller what movement he
desires with a finger switch, a switch on the
controller, or an external or implanted joystick.
The computer/controller is custom-programmed with
movement patterns for each individual user. Thanks
for your offer to volunteer.
