Spontaneous dyskinesia is associated with non-affective psychosis. Few studies investigated dyskinesia in individuals with subclinical psychotic experiences. We examined dyskinesia using instrumental measurements of force variability in 34 individuals with frequent auditory verbal hallucinations but without a clinical psychotic disorder and 31 matched healthy controls. Schizotypy was assessed using the Schizotypal Personality Questionnaire. We found a positive correlation between dyskinesia and schizotypy in the total group. In addition, when using a cut-off point based on the 95th percentile of force variability in the control group, we found a greater proportion of subjects with dyskinesia in the group with auditory verbal hallucinations than in the control subjects. Current findings are in agreement with the concept of psychosis as a continuous phenomenon and with movement disorders being an integral part of psychosis.
自发性运动障碍与非情感性精神病有关。很少有研究调查有亚临床精神病体验的个体的运动障碍。我们使用仪器测量了 34 名经常出现听觉言语幻觉但没有临床精神病障碍的个体和 31 名匹配的健康对照者的力变异性，以检查运动障碍。使用精神分裂症人格问卷评估精神分裂症倾向。我们发现整个组中运动障碍与精神分裂症倾向之间存在正相关。此外，当使用基于对照组力变异性第 95 百分位数的截断值时，我们发现听觉言语幻觉组中运动障碍的受试者比例大于对照组。目前的研究结果与精神病作为一种连续现象的概念以及运动障碍是精神病的一个组成部分的概念一致。
