Thalamic deep brain stimulation (DBS) for chronic pain is performed in selected patients with a variable success rate. We report the use of recently developed directional DBS in a patient with hemibody central poststroke pain (CPSP) and its added value in the induction of pleasant, pain-distracting paresthesia’s throughout the contralateral body side. A 68-year-old man suffered from multiple strokes in the left hemisphere 11 years before presentation, resulting in medically refractory right-sided hemibody CPSP. He was implanted with a directional DBS electrode in the left ventrocaudal nucleus of the thalamus. A directional single-segment contact configuration produced a better improvement throughout the contralateral body side than ring-mode and other directional configurations. Treatment led to a reduction of almost 50% in pain. This case demonstrates the value of directional DBS in the treatment of chronic pain, as steering increases selectivity and reduces side effects in a small target area surrounded by structures with high functional diversity.
