已经证明，互动的人的运动协调在社会交流的成功中起着至关重要的作用。据报道，精神分裂症患者在人际交往过程中会出现异常运动，运动协调障碍可以解释这种社会交往缺陷，这是这种疾病的主要和最早的特征之一。使用动力系统的框架，目前的研究的目标是（i）调查是否社会运动协调受损的精神分裂症和（ii），以确定潜在的感知或认知过程，可能会受到影响。我们研究了有意和无意的社会运动协调的参与者从手腕振荡的手持哑铃。对照组由20对健康参与者组成，而实验组由20对参与者组成，其中包括一名患有精神分裂症的参与者。结果表明，无意识的社会运动协调被保留，而有意的社会运动协调受损。在有意协调中，精神分裂症组显示出稳定性较低的协调模式，并且患者从未领导过协调。耦合振荡器模型表明，精神分裂症组协调模式是由于可用信息量的减少以及信息传输的延迟。因此，我们的研究确定了精神分裂症的关系运动特征，并为检测疾病和改善患者的社会交往开辟了新的视角。
It has been demonstrated that motor coordination of interacting people plays a crucial role in the success of social exchanges. Abnormal movements have been reported during interpersonal interactions of patients suffering from schizophrenia and a motor coordination breakdown could explain this social interaction deficit, which is one of the main and earliest features of the illness. Using the dynamical systems framework, the goal of the current study was (i) to investigate whether social motor coordination is impaired in schizophrenia and (ii) to determine the underlying perceptual or cognitive processes that may be affected. We examined intentional and unintentional social motor coordination in participants oscillating hand-held pendulums from the wrist. The control group consisted of twenty healthy participant pairs while the experimental group consisted of twenty participant pairs that included one participant suffering from schizophrenia. The results showed that unintentional social motor coordination was preserved while intentional social motor coordination was impaired. In intentional coordination, the schizophrenia group displayed coordination patterns that had lower stability and in which the patient never led the coordination. A coupled oscillator model suggests that the schizophrenia group coordination pattern was due to a decrease in the amount of available information together with a delay in information transmission. Our study thus identified relational motor signatures of schizophrenia and opens new perspectives for detecting the illness and improving social interactions of patients.
