New device may reduce side effects of FES

A new method of nerve stimulation may reduce the painful side effects experienced by patients with nerve damage undergoing functional electrical stimulation (FES) treatment.

Researchers have found a way to reduce the electrical threshold of an electrical neurological stimulation device by 40 per cent.

Dr Samuel J. Lin, a surgeon at Beth Israel Deaconess Medical Centre and lead author of the study, stated: "The new device works by manipulating the concentration of charged ions surrounding the nerve.

"This could potentially mean reduced risk to surrounding nerves because less electrical current is required."

While FES has proven benefits for upper and lower extremity injuries and spinal cord damage, patients have reported unwelcome side effects.

It is hoped that the new device will negate the side effects of nerve damage treatment, which has been proven effective for improving the walking abilities of Parkinson's patients.

The treatment is also vital for multiple sclerosis treatment and for stroke rehabilitation.
