In this review, we summarize recent advances in understanding the etiology, risk factors and pathophysiology of focal task specific dystonia (FTSD), movement disorders characterized by abnormal motor activation during the performance of specific, repetitive actions. We focus on two common FTSD, musician's dystonia and writer's cramp. FTSD may pose a threat to the patient's livelihood, and improved therapeutic treatments are needed.
