An international team has developed an implantable neuroprosthesis in the spinal cord that can interact with various robotic devices and enable movements in people with severe spinal cord injuries. The study, conducted in nine patients, showed that the device facilitated robotic-assisted walking and cycling and promoted neuromuscular activation. The results are published in the journal Science Robotics.  

A multidisciplinary team of researchers in the United States has implanted a paralysed person with a brain-computer interface capable of detecting and decoding finger movements. The system achieved a degree of accuracy that allowed him to play a video game. The results are published in the journal Nature Medicine.

A clinical trial involving 60 people with upper and lower body paralysis showed that a non-invasive electrical spinal cord stimulation device - called ARCEX - helps improve hand and arm function in quadriplegic patients. The study, the results of which are published in Nature Medicine, showed that 43 of the people with paralysis experienced improved arm and hand strength and function after receiving electrical stimulation along with rehabilitation exercises.  

A neuroprosthesis that electrically stimulates an area of the spinal cord of a man with Parkinson's disease improved his mobility and balance, according to results presented in Nature Medicine. The 62-year-old patient had severe difficulties walking and frequent falls, despite trying other treatments. After trials in non-human primates, this is the first time this technology has been tested in a human being, who has now been using the neuroprosthesis about eight hours a day for two years.
