Jan Scheuermann is now able to easily grasp and move a variety of objects just like a normal human arm. Brain implants were used to control the robotic arm, in the study reported in the Lancet medical journal.
Jan was implanted with two sensors, each four millimeters by four millimeters, in the motor cortex of her brain. Jan was able to control the arm after the second day of training and over a period of 14 weeks became increasing skilful.
The report said she gained “co-ordination, skill and speed almost similar to that of an able-bodied person” by the end of the study.
Jan earlier progressively lost control over her body since she was diagnosed with spinocerebellar degeneration 13 years ago but with the help of the robotic-arm controlled by her brain, she’s now able to pour herself a glass of water to drink.
