Dystonic postures generated from complex repetitive discharges

Article abstract-We report a woman with a chronic inflammatory myopathy who developed muscle stiffness and dystonic postures of both upper extremities. Electromyography demonstrated that involuntary complex repetitive discharges of muscle caused the posture. Rare cases of dystonic posturing may be of peripheral, and not central nervous system, origin. NEUROLOGY 1996;46: 257-258
