Abstract

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.

双重任务对精神分裂症患者体位控制的影响。

目的:探讨双重任务对精神分裂症患者体位控制的影响。方法:15例精神分裂症门诊患者和15例健康对照。采用平衡大师系统(Balance Master System)对三种不同任务:单任务(站在力台上)、认知任务(分类语言流畅性)和运动任务(拿着一杯水)在坚实表面睁眼(1)和闭眼(2)、泡沫表面睁眼(3)和闭眼(4)下的姿势控制进行了体位摇摆速度(PSV)评估。结果:精神分裂症个体在泡沫表面睁眼和闭眼单站立时PSV更高。在认知任务中，闭着眼睛的受试者在泡沫表面表现出更高的PSV。在运动任务中，精神分裂症组在闭眼坚硬表面和睁眼闭眼泡沫表面的PSV较高。精神分裂症患者闭着眼睛在坚实表面的认知任务中表现出更高的PSV。结论:双重任务导致精神分裂症患者的姿势控制恶化。在缺乏视觉信息的情况下，认知任务特别改变了姿势控制，这表明该人群可能存在感觉运动功能障碍。

期刊介绍： The Journal of Musculoskeletal and Neuronal Interactions (JMNI) is an academic journal dealing with the pathophysiology and treatment of musculoskeletal disorders. It is published quarterly (months of issue March, June, September, December). Its purpose is to publish original, peer-reviewed papers of research and clinical experience in all areas of the musculoskeletal system and its interactions with the nervous system, especially metabolic bone diseases, with particular emphasis on osteoporosis. Additionally, JMNI publishes the Abstracts from the biannual meetings of the International Society of Musculoskeletal and Neuronal Interactions, and hosts Abstracts of other meetings on topics related to the aims and scope of JMNI.
