OBJECTIVE
To investigate the effect of dual tasking on postural control in individuals with schizophrenia.
METHODS
Fifteen outpatients with schizophrenia and 15 healthy controls were included. Postural control was assessed with postural sway velocity (PSV) using Balance Master System during three different tasks: single task (standing on a force platform), cognitive task (categorical verbal fluency) and motor task (holding a cup of water) in four conditions: on firm surface with eyes open (1) and closed (2), on foam surface with eyes open (3) and closed (4).
RESULTS
Individuals with schizophrenia presented higher PSV during single standing on foam surface with eyes open and closed. During the cognitive task, they showed higher PSV on foam surface with eyes closed. During the motor task PSV in schizophrenia group was higher on firm surface with eyes closed and on foam surface with eyes open and closed. Individuals with schizophrenia showed higher PSV during cognitive task on firm surface with eyes closed compared to the single task.
CONCLUSIONS
Dual tasking results in a deterioration in postural control in individuals with schizophrenia. A cognitive task specifically alters postural control in the absence of visual information suggesting a possible sensorimotor dysfunction in this population.
目的
研究双重任务对精神分裂症患者姿势控制的影响。
方法
纳入 15 名精神分裂症门诊患者和 15 名健康对照者。使用 Balance Master 系统评估姿势控制，评估指标为姿势摆动速度（PSV），在三种不同任务下：单任务（站在力平台上）、认知任务（类别言语流畅性）和运动任务（持一杯水），在四种条件下：在坚固表面睁眼（1）和闭眼（2）、在泡沫表面睁眼（3）和闭眼（4）。
结果
精神分裂症患者在单脚站立于泡沫表面睁眼和闭眼时 PSV 较高。在认知任务中，他们在泡沫表面闭眼时 PSV 较高。在运动任务中，精神分裂症组在闭眼时的 PSV 在坚固表面和泡沫表面睁眼和闭眼时较高。与单任务相比，精神分裂症患者在闭眼时进行认知任务时 PSV 较高。
结论
双重任务导致精神分裂症患者姿势控制恶化。认知任务在没有视觉信息的情况下特别改变姿势控制，这表明该人群可能存在感觉运动功能障碍。
