TOMSK, Jun 17 –
RIA Tomsk. Scientists of Tomsk Polytechnic University (TPU) plan to create an
artificial limb which will cope signals of a brain and move as a healthy
extremity by 2018, the press service of the higher education institution
reported.
It is explained
that there are already mobile traction artificial limbs now. They fasten
special belts to a healthy shoulder, and due to its movements the artificial
extremity can carry out some operations too. The main lack of such artificial
limbs is that for management it is necessary to carry out the unnatural
movements.
"The
sensors located on the artificial limb (developed in TPU) will catch a
myoelectric signal. Human brain sends the signal to muscles, forcing them to
make necessary actions. The system will analyze the "instruction"
coming to healthy part of the hand and "guess" which action the
artificial limb has to make", – it is said in the message.

According to the
higher education institution, the staff of the laboratory of medical
instrumentation of TPU Mikhail Grigoriev, Nikita Turushev and Evgeny Tarakanets
work on the device and the software for it. They have got a grant of the
Russian Fund of Basic Researches (RFBR) for development of the limb software
and have to finish work until the end of 2017.
It is specified
that initially the program will be universal, but it is possible to adapt it
under each case. Subsequently it will adapt to the patient: "to
remember" features of myoelectric signals and to select the necessary
movements. For "training" of the artificial limbs scientists will
have to study at least 150 people having healthy extremities.
