Treatment for stroke survivors is being revolutionised by neuro-scientists at Auckland University.

They have developed a way to fast-track recovery using electro-magnetic equipment to activate dormant brain cells.

Lead researcher Dr Cathy Stinear said the technique prepared the brain when used immediately before a physiotherapy session.

“We can excite the neurons on the side of the brain affected by stroke. It’s like warming a car before you go for a drive on a cold morning,” she said.

Stinear said the technique, known as Transcranial Magnetic Stimulation, was safe and painless. The machine was placed against the scalp near the section of the brain in control of movement.

After a few minutes, the device was removed and patients went about their regular physiotherapy exercises.
