After a bad stroke, Judy Slater had fallen and couldn’t get back up. It had caused paralysis of her whole left side. With time Judy was able to walk, but in the 2 years of recovery her left arm remained almost entirely immobile with her elbow stuck at 90 degrees. Her hands and fingers had curled up, and she couldn’t extend them on her own.

Judy’s experience is not unknown. Many people suffer from strokes which cause long-term disability. In fact Strokes are the leading cause of adult disability in Canada. Every year in Canada there are over 50,000 new strokes. That means about 426,000 Canadians are living with the effects of a stroke. Statistics show that more than half of all people with a stroke will continue to have severe movement impairments.

Judy agreed to become the first patient to receive deep brain stimulation (DBS) for stroke recovery after longing for her former independence. A procedure where electrodes are implanted in the brain to provide small electric pulses. The procedure took place at the Cleveland Clinic.
