The epidemiology of generalized and focal dystonias was investigated in the Rochester, Minnesota, population over the period 1950-1982. The crude incidence of generalized dystonia was 2 per million persons per year, and for all focal dystonias combined, 24 per million per year. The crude prevalence rate was 34 per million persons for generalized dystonia and 295 per million persons for all focal dystonias. Torticollis was the most common focal dystonia; essential blepharospasm, oromandibular dystonia, spasmodic dysphonia, and writer's cramp were less common and had roughly equal incidence and prevalence rates.
1950年至1982年期间，对明尼苏达州罗切斯特市人群的全身性和局灶性肌张力障碍的流行病学情况进行了调查。全身性肌张力障碍的粗发病率为每年每百万人2例，所有局灶性肌张力障碍合并计算为每年每百万人24例。全身性肌张力障碍的粗患病率为每百万人34例，所有局灶性肌张力障碍为每百万人295例。斜颈是最常见的局灶性肌张力障碍；原发性睑痉挛、口下颌肌张力障碍、痉挛性发音障碍和书写痉挛则较少见，且发病率和患病率大致相当。
