Said Jamie Henderson of the Faculty of Medicine at the University
Stanford, California, states that previous experiences have had some success in
Take advantage of brain sensors connected to computers modified in
Help paralyzed patients write up to eight words per minute, but experiment
The current aims to help patients use tablet PCs
And smart phones without any special modification.
Henderson added to an email
"We may still have years to come up with a device that can be planted and approved
The United States Food and Drug Administration (FDA) must be made available to users
Range. I am convinced, however, that most technological barriers have been removed
In the near future, we will see badistive devices allowing people with paralysis to control
A computer using their own ideas. "
The trial included only three patients, two of whom
They are weak or unable to move their arms and legs due to lateral sclerosis.
And the third patient was paralyzed because of an injury to the spine.
Scientists have installed devices the size of an aspirin in a region of the brain called the motor cortex, responsible for planning and conducting voluntary movements.
The purpose of the device implantation is to monitor the signals
Associated with the desired movements, then transfers these signals to a device using Bluetooth,
Designed to work as a wireless computer mouse connected to a Google tablet computer
Nexes 9 "did not submit to the amendment scientists on this subject.
With the help of wireless sensor and "mouse"
Participants in the experiment were able to navigate through popular programs on one device
Tablet PC, among which e-mail, chat and run applications
Music and video
It also allows patients to send messages to their loved ones
Friends and members of the research team, and among them, the participants also took part in
Internet, weather and online shopping.
One of the patients played the piano and managed to play a piece of Beethoven's Ninth Symphony.
The researchers wrote in the newspaper (Plus One) that
The participants were able to perform up to 22 task shifts and clicks per minute,
Use different applications.
For text applications, participants could write up to 30 characters per minute.
The experiment was conducted by a team of doctors, scientists and engineers.
The panel noted before that the device used
In the current experiment, people can move the arms of the mechanism or regain control.
On their limbs, despite their loss of mobility due to injury or illness.
Said the deputy director of the neuroscience program
At Carnegie Mellon University in Pittsburgh, Pennsylvania, Stephen Chase: "The only
Experience shows that they do not require modification of the tablets but can be applied to
The same devices used by people in good health. "
"I mean," said Chase, who did not participate in the experiment
Indeed, it will not be necessary to design special software for users of these devices.
Significantly increases the number of applications that these patients will be able to treat "
