Post-traumatic paroxysmal exercise-induced dystonia: case report and review of the literature.
A young Chinese man sustained a back injury in a motorcycle accident in 2000 and had left lower limb weakness due to a lumbosacral plexopathy, diagnosed clinically and electromyographically. With rehabilitation, he recovered full function, but developed paroxysmal dystonia of the left leg only with prolonged exertion. He responded well to oral baclofen, relapsed when he stopped taking it, and remains well on low dose maintenance therapy. Dystonia occurring after trauma is well documented, but paroxysmal exercise-induced dystonia occurring after trauma has yet to be described. Paroxysmal exercise-induced dystonia responds variably to anticonvulsant therapy, but the literature does not report response to baclofen, especially in low doses.
