The
kick-off the FIFA World Cup in Brazil, during the Opening Ceremony, on
June 12, will be the most exciting moment for scientists working in
developing a mind controlled exoskeleton, the robotic armor that
supports from the outside the body... (you can read my previous post including a Twitter conversation with Professor Nicolelis; Italian version).
This
month the Mayo Clinic Proceedings published a “concise review” of the state
of the art in the Brain Machine Interface and limb reanimation
technologies by Lobel D.A., Lee K.H., Brain Machine Interface and Limb Reanimation Technologies: Restoring Function After Spinal Cord Injury Through Development of a Bypass System.
“To date, signal processing algorithms have been designed for asynchronous BMI [Brain Machine Interface] control, however, no complete BMI systems have produced a sufficient online efficiency rate with a low enough false-positive rate to provide a reasonable clinical safety profile.”
Moreover,
as explained by Lobel and Lee, current BMI systems are not able to
capture activity in subcortical pathways.
“Therefore, details regarding how the signals are delivered to motor neurons to effect simple limb movements, such as flexion and extension of specific muscles, as well as more complex movements such as gait, will have to be surmised from experimental ISMS [IntraSpinal MicroStimulation] studies”.
On
June 12, a paraplegic person will kick
the first
ceremonial ball
of the FIFA World Cup, wearing a
mind controlled exoskeleton. This seemingly simple action requires
the movement of a leg, the alternation of the two legs, the kick-off
and the postural balance of the exoskeleton.
It
will be hard to achieve. On one hand, the experimental research on
mind controlled exoskeletons is at an early stage in humans and, on
the other hand, it's more likely that restoring function after
spinal cord injury will be based, in the future, on the integration of
different technologies.
The aims
of restoring neurological functions and helping individuals with
paralized limbs, need to be accomplished by engineering new
technologies that can be used safely, effectively and at any time, at
home.
Lobel
and Lee hypothesize that a major challenge in this direction is the
development of a bypass system combining BMI and limb reanimation
systems.
“Because both the BMI and ISMS systems are in relatively early stages of development, we are afforded an opportunity to tailor the design of combined bypass systems to include functions such as providing sensory feedback that will maximize the benefit for patients with SCI [Spinal Cord Injury]”.
Experimental
studies need funding. Thus, an Opening Ceremony, celebrated
worldwide, represents a unique advertising opportunity to show an
ambitious research project, although in the very early stages of its
evolution.
It
will also be a great moment of awareness if and only if the message
and the media coverage will be able – and deem convenient - to
distinguish the aims of experimental research and its applications
that are strictly limited to the laboratory, from the aims of clinical
rehabilitation that provides behavioral treaments and technological
systems proven effective for improving everyday functioning
in the real life.
In summary, the idea is to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgement in one particular direction or another.
The easiest way to explain this idea is to contrast it, for example, with advertising. Richard Feynman
