Mirror Therapy May Reduce Phantom Limb Pain
Looking in the mirror may be good for more than straightening your tie.
A new study suggests that phantom limb pain, which 90 percent of
amputees experience, can be lessened by a technique called mirror
therapy. The study was reported in a letter in the New England Journal
of Medicine’s November 22, 2007 issue.
According to the Web site WedMD.com, the study incorporated 18
patients, who each felt phantom pain from an amputated foot. The
patients were split into three groups of six. Those in the mirror group
watched a reflection of their intact feet in a mirror while mentally
moving their phantom amputated limbs.
The second group performed movements with their intact limbs and
mentally moved their amputated limbs while the mirror was covered by an
opaque sheet. The third group performed only a mental visualization,
with their eyes closed, of moving their amputated limb.
The patients practiced their particular exercises for 15 minutes a day
for four weeks, also keeping track of the number and duration of
episodes of phantom limb pain, and the intensity of the pain they felt.
All of the patients in the mirror group reported a drop in all three
aspects of their phantom limb pain. Only one patient in the covered
mirror group did, while three of them reported worsening pain. Of the
patients in the visualization group, two reported a positive
difference, and four reported a change for the worse.
Phantom limb pain also decreased in eight of nine patients who switched
to mirror therapy from one of the other groups after the first four
weeks.
The researchers involved were affiliated with Walter Reed Army Medical
Center in Washington, D.C., Malcolm Randall Veterans Affairs Medical
Center in Gainesville, Fl., and Uniformed Services University of the
Health Sciences in Bethesda, Md.
The researchers suggest in their letter that the pain relief gained
from mirror therapy may be due to activation of mirror neurons in the
hemisphere of the brain opposite from the side of the body with the
amputation. These neurons fire when a person performs an action or
observes another person performing an action. The mechanics of this
phenomenon are not fully understood, but the researchers believe that
mirror therapy could help amputees substantially reduce their phantom
limb pain.

Brain2Robot Could Help Paralyzed Patients
The Fraunhofer Institute for Computer Architecture and Software
Technology (FIRST) in Berlin is working on a robotic-limb control
system based on the eye movements of the user.
According to the Institute’s Web site, the Brain2Robot program
would allow paralyzed individuals to have the direction of their gaze
monitored by a special pair of eyeglasses. Another tracker would
determine the direction of the head. Using these two forms of feedback,
the software component of the device would direct the robotic arm to
move and grasp.
The movement of the robotic arm is triggered by a signal from a
brain-computer interface. The interface uses an EEG to measure brain
signals, which are then analyzed by the computer to identify patterns
of thought which correspond with moving a limb in a particular
direction.
The FIRST system puts the bulk of the learning responsibility on the
computer, which uses algorithms to analyze data and allows the patient
to learn to use the system in a simple 30-minute session. The patient
learns to look in a particular direction as a signal to the computer
that it intends a particular movement.
FIRST hopes to make the Brain2Robot system available for medical
applications including prosthetic control systems and robotics mounted
on wheelchairs.
The program is funded by a Marie Curie Excellence Grant from the EU 6th Research Framework Programme.

Piezoelectricity Could Spark Prosthetic Advances
According to an article in Science Daily, a University of Houston
research team is working on using piezoelectricity, the ability of some
materials to generate an electrical charge when placed under stress, to
enhance the flexibility and strength of prosthetic limbs.
Piezoelectrics may sound technical, but it’s involved in everyday
things such as how a lighter works and how airbags deploy.
For example, an engineered piezoelectric strip in a soldier’s
boot would generate electricity with every step of the walking motion,
since exerting force on the strip would bend it and generate
electricity that could power devices that soldiers carry.
Man-made piezoelectrics could conceivably be harnessed to build
prostheses that provide better energy return and natural movement,
since current prosthetic limbs face challenges in range and movement
when using two types of naturally occurring piezoelectrics, ceramic and
polymer.
“Ceramic piezoelectrics are very hard and brittle, and
don’t allow for a lot of movement,” says Pradeep Sharma,
the mechanical engineering professor who leads the UH team.
“They take a lot of electrical energy for a lot of motion.
Polymers are better for large forces of motion, but don’t have a
lot of strength. We wanted to combine the best qualities of the two
types of piezoelectrics.”
Sharma is creating piezoelectrics from man-made materials that have no natural piezoelectric properties.
A $1.22 million grant from the National Science Foundation will fund the testing phase of the project.

China in Need of Lower-Cost, Higher-Quality Prostheses
China’s trade surplus with the western world is established.
However, China does not produce prosthetic limbs in anything like the
quantities in which it produces many other goods. Further, the
prosthetic limbs China does produce are of quality too poor to make an
appreciable difference in the lives of its more than 2 million
amputees, according to China Daily.
Most of the 600 factories which produce prostheses or components are
producing simple parts which are then used by foreign manufacturers.
There are also many fewer prosthetics experts in China than in other
countries––less than one-quarter of those in Japan, the
United States, or Germany.
Some affluent Chinese, or those with national hero status, are able to
purchase Western-made prostheses, but only products from Germany, Great
Britain, or France are available to them. The cost of these imported
prostheses is beyond the reach of the average Chinese consumer.
Lacking government backing, most disabled Chinese have no way to obtain
quality prostheses. Advocates for China’s O&P industry are
counting on the Paralympic Games being held this summer in Beijing to
increase awareness of China’s disabled population and potentially
encourage those empowered to find solutions to do so.
