Concurrent cognitive and motor tasks in ataxic individuals cause functional limitations and negatively affect the independence of patients in daily life.
This study aimed to examine the effects of dual task on postural control and spatiotemporal parameters of gait in ataxic individuals.
The study included 20 individuals with ataxia. Disease severity was evaluated using the International Cooperative Ataxia Rating Scale. A force platform was used to evaluate postural sway and limits of stability and a GAITRite electronic walkway to evaluate the spatiotemporal parameters of gait. Postural control and gait were evaluated without a simultaneous task (task-1) and with dual tasks consisting of counting the names starting with "a selected letter such as A" (task-2), counting backwards aloud in threes from 100 (task-3), carrying a glass of water with a tray (task-4), and speaking on a mobile phone (task-5). The effects of dual task on postural control and gait parameters were examined with multiple comparisons.
The tasks requiring cognitive skills (tasks 2, 3, 5) were determined to have a greater effect on the increase of body sway, and gait was seen to be affected by motor and/or cognitive tasks (tasks 2, 4, 5).
From the results of the present study, it is thought that evaluations of postural control and gait performance of ataxic individuals together with the dual tasks they may encounter in daily life are important in terms of their independence in activities of daily living.
共济失调个体同时进行认知和运动任务会导致功能受限，并对患者日常生活的独立性产生负面影响。
本研究旨在探讨双重任务对共济失调个体的姿势控制和步态时空参数的影响。
本研究纳入了 20 名共济失调患者。采用国际合作共济失调评分量表评估疾病严重程度。使用力台评估姿势摆动和稳定性极限，使用 GAITRite 电子步态分析系统评估步态时空参数。分别在无同步任务（任务 1）和进行双重任务（任务 2：数以字母 A 开头的名字；任务 3：从 100 开始大声数 3 个数；任务 4：端着托盘喝水；任务 5：用手机通话）的情况下评估姿势控制和步态。采用多重比较检验双重任务对姿势控制和步态参数的影响。
需要认知技能的任务（任务 2、3、5）被确定对身体摆动增加有更大的影响，并且发现步态受到运动和/或认知任务的影响（任务 2、4、5）。
根据本研究的结果，评估共济失调个体的姿势控制和步态表现以及他们在日常生活中可能遇到的双重任务，对于他们日常生活活动的独立性非常重要。
