Technologists at Ossur prosthetic company in Iceland have developed a new type of bionic legs for the people without lower limbs. Successful clinical trials carried out since last year have resulted in the handicapped persons walking without hardships.
The technology works through muscle myoelectric sensors, which are implanted in lower limbs muscles of the patients. These sensors are used to control the bionic legs just by the use of brain. Previous prosthetic implementation required the grafting of nerve fibres on the limb controlling muscles to receive and send feedback signals through spinal cord to brain. But this time, the latest technique works wireless! . It means, myosensors don’t depend on nervous system to receive motor signals form brain. A person just thinks of moving his bionic legs and the brain signals are transmitted directly to the required prosthetic.
According to an in-trial patient Olaffson, who had his left foot amputated in a child hood accident shared his life’s most memorable moments in such words.” As I put on the bionic legs, it took me just 10 minutes to fully control it’s movement. It seemed as if I had walked on my natural limbs. It was like, I have moved it myself, no one else was doing it .It was an amazing experience and an over whelming one .
Implanting the sensors is a 15 minutes surgical procedure and it takes just a centimeter of incision to insert and stick these sensors to the muscles. The sensors are life long and don’t need to be replaced in the future, except for some extreme medical complications.
The research and development in the field of mind controlled prosthetic limbs technology has been going on for many years now, but this time the procedural implementation doesn’t require complex surgeries and once the foot is attached, it works for a prolonged period of time.
Ossur company, the mastermind behind the procedure, hopes to start mass production of its bionic legs product, once the trials are completed. The technology indirectly reduces the chances of muscle atrophy on the handicapped persons, as they put into use their previously non-functioning muscles.
