In their latest work on CES, Webber's group examined animal models with foot drop, a common injury that affects patients' quality of life by impeding their ability to walk normally. Previously, the only treatments for foot drop were orthotics that affect a patient's gait, or surgery.
Webber's lab performed a distal nerve transfer in which a nerve near the damaged one was electrically stimulated, then a week later a branch of the nerve was cut and placed near the target of the non-functioning nerve. The newly transferred nerve would then be primed and ready to regrow, at a much faster rate, into the muscles that lift the foot.

Sometimes a nerve is persistently tender. This is usually due to a neuroma. Wrapping a vein, fat or another substance around your nerve provides padding around the nerve and will make the area less sensitive.
After a nerve is injured, sometimes painful neuromas develop in smaller nerves of your hand. They are usually in locations that are not suitable for nerve repair such as amputated fingers. I can cut away the neuroma and bury the nerve end deep in a muscle or bone. This prevents the nerve end from being knocked and should reduce the electric shock like pain.
The area that the nerve supplied will be completely numb, and this is permanent. You will be given antibiotics at the beginning of your procedure and occasionally after your operation. Antibiotic use is carefully monitored to reduce antibiotic resistance. The signs of infection to look out for include increasing redness, swelling, pain and purulent discharge. Most wound infections will respond quickly to antibiotics. Very occasionally further surgery may be required to clean out a deeper infection.
Infection can lead to delayed recovery and increased stiffness. This phosphorylation makes the nerve grow faster, according to research that Sahoo and Twiss's team published in The study took a step back to look for the processes that trigger the phosphorylation, in hopes that the entire process could be accelerated.
The process seems to be regulated by calcium ions. These discoveries offer promising areas for further study. Finding that key could lead to advances in medicine that result in faster healing after nerve injuries.
