Transcutaneous Electrical Nerve Stimulation

Although conditions such as epilepsy can be treated via nerve-stimulating electrodes, those electrodes are stiff, costly and require surgery to implant. Scientists have now created an alternative, however, in the form of soft, injectable electrodes.

Electrical stimulation of the vagus nerve holds all kinds of possibilities in medical science, and scientists have now added another to the list by demonstrating how targeting it through the ear could help slow some of the effects of aging. ​

In a landmark study, researchers from Northwestern University and the Washington University School of Medicine describe a novel biodegradable implant designed to electrically stimulate damaged nerves, speeding up the healing process, before naturally dissolving into the body.

A new study describes progress in a groundbreaking technique that is helping paraplegic patients walk again. The experimental process, involving electrically stimulating the spinal cord, is proving increasingly promising as research works to improve the design of the treatment.

Although medication can help with motion sickness, it also causes side effects such as drowsiness. In a few years, however, there may be a preferable alternative ... which users would stick to their head.

Working with a team of UCLA scientists, a man with protracted and complete paralysis has recovered sufficient voluntary control to take charge of a bionic exoskeleton and take many thousands of steps.

Five men with complete motor paralysis regained the ability to move their legs voluntarily after being treated with a non-invasive form of spinal cord stimulation called transcutaneous electrical nerve stimulation, which involves strategically placing electrodes on the skin of the lower back.

Joining the sizable chunk of the wearable electronics market directed at maintaining our physical well-being is start-up Quell, which bills its device as the first over-the-counter wearable that offers relief from chronic pain.
