By stimulating nerves, a new wearable cuff “rewires” the brains of stroke victims.

In a limited study of stroke patients, an understated and flexible electrode armband was found to help restore flexibility in the immobilized arms.

The device, which is being produced by a startup company named Neubond, is meant to fit in smoothly with everyday activities so that those who have limited motor function can spend as much time as possible engaging in rehabilitative activities.

Neubond has been refining its technology in collaboration with patients from a stroke support group in London, close to the Imperial College London campus. The team is directed by co-founders Jumpei Kashiwakura and Patrick Sagastegui Alva. The findings were released in a recent NYU Scholars journal paper.

The prototype armband is worn around the upper forearm and contains electrodes placed in it that can detect commands for muscle activation and stimulate nerves to aid in the restoration of the brain’s link to the muscles.

According to co-founder Kashiwakura, the mechanism by which the gadget regains control of the limb is through fostering neuroplasticity, or the brain’s rebuilding around new neural pathways.

Lisa Vincent’s left arm went from being totally rigid to being able to bend and flex with significantly more control after just 8 sessions, according to Reuters.

“My eight-month-old granddaughter was only permitted to sit on my lap since I was unable to handle her. However, three weeks prior, my daughter placed her on my lap, and I supported her with this arm since I felt confident enough and in control of my wrist..
