"Our findings show that several brain structures are abnormal in writer's cramp, including the cerebellum, suggesting that the cerebellum plays a role in the disease," Lehericy said. "The role of this structure in the disease will probably be investigated in more detail in animal models (some animal models have abnormalities in the cerebellum) and also in humans. Moreover, cerebellum is involved in motor control and scaling of fine movements and this may influence the way rehabilitation will be performed," he said.
The Dystonia Society has more on writer's cramp.
