A new method to treat dystonia, a group of diseases which cause muscles to involuntarily contract with movement, has been successfully tested by researchers in the US.

Deep brain treatment, a surgical procedure akin to flipping an ‘off’ switch in the brain, has yielded positive results for some patients.

Initial testing of the technique has shown that the treatment is more effective than other existing methods, according to a study published in Neuromodulation.

Researcher Dr. Kathryn Holloway said: “We knew from early studies that a certain type dystonia has a dramatic response to surgery.

“What was not clear, prior to this study, was whether patients with other types of dystonia would also respond in a similar fashion.”

 The surgery is most effective when it is performed in the initial stages of the disease.

Dystonia can affect muscles throughout the entire body, in certain parts of the body, or only particular muscles.
