all while we are in a world that
changes very quickly and now what
Very often we hear about is to
the bionic man to man up
artificial limbs
I’ll go a little bit contrepied
of it and I’ll tell you about
prosthetic lower limbs
Member theses to do elsewhere
nevertheless it remains a member
artificial and I will present
these aspects in biomechanics and rock
Also I wrote about
the equipment which is a wonderful profession
of adapting a system
Artificial a good person
particular to replace anatomy
she lost that before you speak
two mechanical I would just
have a few words about the disability
Disability is a concept which is the former
includes getting better now
and the handicap can be set under
three aspects or at least be three
shuttered the concept of disability
the first most important thing
This is the project of a person’s life
second thing is that this person
it is an individual he is unique
be differences between hop there I
can influence this handicap
and this handicap he will have effects
that will be more or less important
depending on the environment in
which in situations of person
Disability is the society
which the company operates will
limit or barriers that will try
limit disability or at
otherwise will not do much
for it a company that will decide
to support this disability
higher or lower level as the
handicap which is basically a
limiting its interaction with its
environment will affect
all of these three components or I
working in a laboratory
Biomechanics and blow the
Biomechanics I talk to you
now
it is a discipline that we
allows to focus a little bit
these three components interest in the project
of a person’s life activities
they realize an interest in
individual specificities of
person to whom we are dealing and
interest or
maybe not the company directly
but in any case the environment in
which these people move so
Biomechanics is a discipline
engineering sciences but who
on the border with the
then the life sciences
biomechanics that are interested in
two enormous difference fields
and it is also more in my case
a tool that allows us to
an interest in locomotion
locomotion it may seem extremely
banal but in the end it is an activity
which is extremely complex by the
that our musculoskeletal system is
extremely complex and is a
Multi its various joints bones
joints will be controlled
a multitude of pink mu have you
a pattern that some musset
represents the action of musks is said
So single joint muscles of August
the hinge having agonists and
antagonists and joints
will depend on the battle between
these two walls are other
muscles called said joint
who are there so we violated monitor
the movement of two joints
successive two that are extremely
important to the thigh and
which is also very important to
the calf that will control the
Once the movement of the foot and
ankle but also the
movement of the knee in the case of a
amputation so a person will lose
part of his lower limbs if
this amputation occurs above
knee will keep or certainly the
surgeon will try to keep the
maximum single joint muscles
but cons in muscles
which was much the joint
surgeon will overhaul the Member
future waste and between its muscles
joint and well this time its
muscles will not have more action
on the hip of the residual
person after the occupation of their
prosthetist rate it will be
design an interface between the member
residual of the person who was
amputated
we will call a car and
prosthetic devices manufacturer
its goal is going to be replaced
Part of the musculoskeletal system which
is lost by devices
Artificial at Knee we will
assemble joints with
Shareholders may be
hydraulic in the foot was
so so much water muscle
so much so ligaments
time so the solution today
more effective and more efficient
is to replace this set of back
and solid by one system but
it will be deformable and thumb
Training will allow it to
magazines and Energy and
then we restore biomechanical
features high-performance tools
with this changing world and therefore
techniques that can be used
now see in animation or
in film of measuring
human movement so it’s a
come say it is a very old
discipline but is now
completely computer
we will be able to measure motion in 3D
is completed velocities
acceleration and torque at the same time
and analyzes the extent of the action
Mechanical exercised man on his
environment, including the soil
blow when designing a component
Today prosthetic what
seeks to do is to quantify the
movement of people
asymptomatic quantify movement
a person who is paired
identify limitations and
offsets its components go
introduce matter by addressing
rigid solids channels or
systems that will be formats
Alongside these analyzes we can
make a person
paired what we want to do
is to develop models
whether experimental or
Digital that will initially
time help us understand how
can operate an artificial limb
how can this mechanical assembly
help us to walk
and in a second time by exploiting
its digital mock what
trying to do is optimize
response of these systems in two
objectives such we can try
optimize an existing components
other life activities
So do daily run
people who until now
or could then sought to
optimize not for components
young athlete but for people
which can be aging and
present other pathologies
today at what
called limb prosthesis
below there is a gold standard that
and is used daily by people
which are paired and it will
provide high level of the knee
sold two systems that are controlled
by microprocessors
suddenly within the prosthesis
you have a multitude of sensors
will allow to estimate recovery
information and to estimate the
situation in which it is
the information will be repatriated
to a microcontroller which is
embark various algorithms and
will come through small
shareholders change response
a mechanical system typically is
will come fly hydraulic valves
to allow a brake more or less
important according to them is what
the person down the stairs is what
she is walking is that
she walks at a high speed
or a reduced speed to sit
helped down slopes feet
prosthetic that’s what I you
talking just now they are
men who are badly in
composite materials to gain
rigidity and lightness which go
allow the person to move
on different environments
urban system and there is today
know they have contributed enormously
to people who are amputees our
days it will improve the quality of
life and improve their security
typically knees with
microprocessors if you stumble the
prosthesis will notice
and rather than let you
completely fallen it will you
brake and prevent that you
come across the floor at hand
2 and current and are components
difficulties persist and
people when the fact they speak
will tell you they have
not on a good field difficulties
horizontal well they will tell you
the difficulties they appear
when it operates outside
their home of these difficulties
will come from a lack of adaptation
of the foot and ankle
you can expect a foot which has a
fixed stiffness that will be fixed
also during the slow phase will make
your toes will be difficult to
clear the ground and when you go
built up a slope it will pique
it increase your risk your
toes touch the ground and caused the
fall
you go down a slope and your
foot to a stiffness which is adapted to
walking flat in December
slope
the stiffness is too high your foot
there will be too late flat that will do
you are going to be longer on
the wedge heel and you necessarily
will increase your risk of slipping
in some situations such as
down stairs and there rigidity
it is designed to walk on
flat with our muscles we
able to permanently change the
equivalent stiffness of the other ankle
who sailed it will
have to compensate for this adaptation
webs of adopting strategies
that will be specific to get
realize actually have to imagine
you descend a staircase with
ski boots you have stiffness
which is far too important
the only way to replace the movement
your ankle it will be put
the middle of your foot on the nose of the
walking and make the rocker around
bell march
that’s what it looks like a
who sailed today
it will be forced to permanently
aim for the middle of the march’s nose
walking with the middle of his foot
to allow the tibia to pass
Above this while walking in the
world there are so many
development and seeking work
solve these problems
today you have solutions or
Hydraulic we will try to put
microprocessors within these
hydraulics to replace
ankle same systems
motor which will therefore change
position said pin and bring
energy to the user we were
instead sought from a
concept a little different I
took time at the beginning of you
talk through joint muscles
because both the twins so
which is our calf therefore a
largest muscles in our legs is a
well-articulated muscle is a muscle
which is inserted above the knee
and which is inserted after the
ankle so we went for it
principle here was drawn on a
paper a living system
joint with a joint at
a knee joint and ankle
a hydraulic actuator has been devised
connecting the two joints
hydraulically connected which allows
transferring energy between the knee and
ankle and after it has sensors
a microcontroller that we will
enable to control the response
This mechanical device
we worked with different
laboratories in Europe
initially to equip our
first prototypes with a multitude
sensors
So it was not necessarily very
attractive initially gather
information and create first
algorithm that allowed us to
locate in our walk cycle
from these sensors in the
questioning to specific times
This cycle of on and ben actually is
is constantly trying
to assess the situation in which the
that person is estimated that
the situation in which we are still
does it bring good adaptation
good time so through a project
was funded by the Agency
National Research could not
work with different centers
Clinical and during that project on
pictures you have left is
we did walk people
asymptomatic and people
paired in situations
they face daily
may bring them trouble
walking in stairs dependent
in cant and what we want
is to measure the compensation they
are forced to implement to
through these and see how we are
fits
what changes
Mechanical and we bring
the video you right is
a prototype where we tried the
first adaptations that could
set up so you see the
person climbing a staircase
show a slope As
Slope
the position of his ankle is actually
adapt to changes and 70
stair descent movement of the
ankle is allowed to end
not only because the
people currently use its
knee is the knee we knew is in
stairs suddenly it only
pass this information to the ankle
reproduces the action of this muscle bj
joint and allows the movement of
puzzle game
moving further and further away one is in
a world that moves extremely fast
in this system where there are
electronics that listened
there are 5 to 6 years ten times a hundred times the price
which costs today and so we know
that in this world of perpetual
development we will be able to go more
and farther and we we want is
we go in real life and that
these technologies are used for
people in their daily here
[Applause]
