Revolutionary spine implants let paraplegics walk again

Scientists in Switzerland have developed a spinal implant system enabling paraplegic patients to walk and cycle. The system includes a gel pack with electric leads tailored for each patient, implanted on the spinal cord. Powered by a pacemaker in the abdomen, it connects wirelessly to a tablet. Patients use the software to choose activities like standing, walking, or cycling. The software sends instructions to the pacemaker, which stimulates nerves to control leg and trunk muscles, allowing movement.
