Down’s children assisted
When you're only two or three
feet tall, people five-feet tall can
be a “big" factor in your life.
A University professor and a
research assistant could be a
very “big" factor in many chil
dren's lives
Marjorie Wollacott and Anne
Shumway-Cook are co-direct
ing research that could estab
lish a more effective therapy
program for children with
Down's Syndrome
The control group for the
research consists of ten “com
munity volunteers’’ between
three- and five-years old Six are
Down's syndrome children and
10 are children without the gen
etic disorder
Down's syndrome is a disease
affecting hundreds of thou
sands of children in the United
States each year. The disease
strikes in the embryonic stages
of development, leaving its vic
tims with learning problems,
lack of muscular development
and sometimes mental retarda
tion
The research, conducted at
the University's Neuromuscular
Control Laboratory, will inves
tigate the activity of the body's
muscular control systems in
maintaining proper balance,
says Wollacott. a physical
education professor
Wollacott and research assis
tant Shumway-Cook designed
and built a hydraulically con
trolled platform. The platform
shifts and tilts, enabling ther
apists to study the movements
children make to maintain their
balance.
Electrodes hooked to an os
cilloscope (a machine designed
to depict, on a screen, periodic
changes in electronic quantity)
allow the researchers to detect
the speed at which a muscle
''fires.” the strength of the
muscle’s reaction and the pat
terns of activity that a group of
muscles present.
"We know that Down's syn
drome children have develop
mental delays — that is, they
may not be able to sit or stand
properly for six months to a year
after normal children,” says
Wollacott "Most researchers
have observed this lack of mus
cle tone and concluded that the
problem lies in the muscles
themselves But we think it may
be due to delayed development
of basic reflexes "
Children experience three
levels of muscular development,
says Wollacott
"Generally reflexes, which
develop first, are very basic
Pulling your hand away from a
hot stove, for example, involves
only the spinal cord and nerves
in the arm," says Wollacott
"However, the automatic re
sponse system that controls
balance and posture is directed
by the brain and isn't fully func
tional until a child is seven or
eight.
"The voluntary system that
controls nearly every kind of
movement and motion requires
the brain, nerves and muscles,
and it continues to develop even
into adult life,” she explains
Current physical therapy for
Down's children uses resistive
training, or making movements
against a weighted force, says
Shumway-Cook
"This kind of training is de
signed to strengthen the volun
tary control system,’1 she says
But Wollacott's research with
normal adults has shown that
any voluntary motion is
preceded by a type of reflex
action. Catching a ball, for in
stance, requires an automatic
response of muscles in the legs
and calves to stabilize and
prepare for the susequent mo
tion involved in catching
The researchers have
developed their hydraulic
platform to measure that au
tomatic response system
"This will give us a detailed
picture of just how each child's
automatic muscular system is
behaving,” says Shumway
Cook

low of the American Association
for the Advancement of
Science
The 130,000-member organ
ization recognized Donnelly for
his "distinguished efforts on
behalf of the advancement of
science ' during its annual
meeting earlier this month
A member of the University
faculty since 1966 Donnelly
and his research group are
studying the hydrodynamics or
movement of superfluid liquid
helium
At about two degrees above
absolute zero, the minus
460-degree temperature at
which all molecular motion
theoretically ceases, liquid
helium undergoes a profound
change in its physical proper
ties A striking example is
superfluidity, the ability to pass
through fine channels or capil
laries without friction
Besides studying superfluid
helium, Donnelly's group is
conducting precision exper
iments on how fluids become
turbulent — for instance, how an
eddy forms in a river The group
also is examining ways to detect
infrared radiation
