The electrodes close around spinal nerves like a book. A tiny, implantable chip that delivers electrical impulses to aid in exercising paralysed limbs has been unveiled by scientists. Similar attempts to promote muscle stimulation have been developed before, but have been too bulky to implant. Thanks to advances in the fabrication of small electronics, the new unit from University College London researchers is smaller than a fingernail. The implants have a number of other possible uses in muscle rehabilitation.
