Researchers in the U.K. have developed a revolutionary microchip muscle stimulator that will enable patients with paraplegia to exercise multiple muscles at the same time. According to the Engineering and Physical Sciences Research Council (EPSRC), the microchip developed by Professor Andreas Demosthenous from University College of London and his team is truly unique.
The microchip chip is small enough (approximately the size of a child’s fingernail) that it can be implanted directly into the spinal canal. Unlike previous models, the new implant incorporates the muscle stimulator and the electrodes into a singular unit. The unit is properly sealed to protect against moisture, which could lead to corrosion of the electrodes.
The creation of the implant has been made possible by new laser processing technology, which enabled researchers to micro-pack all components into one unit. With this new laser technology, researchers were able to cut much tinier electrodes from platinum. The electrodes are then folded into a 3D shape that resembles pages in a book. Each electrode can be wrapped around a nerve root. The electrode is then welded to the microchip located in the spinal cavity.
Because the implant comes with multiple electrodes, which can be connected to multiple nerve roots, it is capable of controlling entire muscle groups. In patients with paraplegia, the devise can be used to stimulate or trigger multiple paralyzed muscles at the same time. Researchers also claim that the new device will also be used in patients with bladder or bowel incontinence. Because the device has multiple electrodes, some electrodes can be connected to nerve roots that control bladder muscles or nerves that control bowel capacity.
Although all of this may sound a bit scifi, the implant will be available for pilot studies sometime this year. If you or someone you know is paraplegic, this research is worth following. It clearly promises to offer life-chaining benefits to patients with paraplegia. If you know of other research on similar devices, we’d love for you to share that information with our readers. We’ll try to keep an eye on the progress and implementation of this device from the UK and keep you posted if and when developments occur.
