Abstract
PURPOSE:The aim of the study was to assess dual-task cost to spatio-temporal gait parameters in people with multiple sclerosis and a matched control group. METHOD:The multiple sclerosis group was composed of 17 participants with a diagnosis of multiple sclerosis and an Expanded Disability Status Scale score of less than 6. A total of 17 healthy participants were allocated to the control group by stratification. Controls were matched on the basis of age, sex, sociocultural habits, and body structure. Dual-task cost was determined by within-group repeated-measures analysis of variance. Participants were instructed to ambulate under normal conditions and perform a discrimination and decision-making task concurrently. Then, between-group analysis of variance was used to assess differences in mean dual-task cost between groups and determine dual-task cost differential. Testing was performed using three-dimensional photogrammetry and an electronic walkway. RESULTS:Based on dual-task cost differential, gait cycle time increase (-5.8%) and gait speed decrease (6.3%) because of multiple sclerosis-induced impairment. CONCLUSIONS:During single- and dual-task conditions, gait speed was lower in multiple sclerosis participants, because of a shorter step length and increased swing time. Increased gait time might be the result of compensatory mechanisms adopted to maintain stability while walking specially during the double-support phases.
摘 要
目的: 本研究的目的是评估多发性硬化症患者和匹配对照组的时空步态参数的双重任务成本。 方法: 多发性硬化组由 17 名诊断为多发性硬化且扩展残疾状态量表评分小于 6 分的参与者组成。共 17 名健康参与者被分层分配到对照组。对照根据年龄、性别、社会文化习惯和身体结构进行匹配。通过组内重复测量方差分析确定双任务成本。参与者被指示在正常条件下走动,同时执行辨别和决策任务。然后,使用组间方差分析评估组间平均双任务成本的差异,并确定双任务成本差异。使用三维摄影测量和电子走道进行测试。 结果: 基于双任务成本差异,由于多发性硬化诱导的损伤,步态周期时间增加 (-5.8%),步态速度降低 (6.3%)。 结论: 在单任务和双任务条件下,多发性硬化症参与者的步态速度较低,因为步长较短,摆动时间增加。增加步态时间可能是在双支撑阶段为保持行走稳定性而采用代偿机制的结果。
期刊介绍
《AMERICAN JOURNAL OF PHYSICAL MEDICINE & REHABILITATION》 (点击进入期刊详情)
英文简介 : American Journal of Physical Medicine & Rehabilitation focuses on the practice, research and educational aspects of physical medicine and rehabilitation. Monthly issues keep physiatrists up-to-date on the optimal functional restoration of patients with disabilities, physical treatment of neuromuscular impairments, the development of new rehabilitative technologies, and the use of electrodiagnostic studies. The Journal publishes cutting-edge basic and clinical research, clinical case reports and in-depth topical reviews of interest to rehabilitation professionals. Topics include prevention, diagnosis, treatment, and rehabilitation of musculoskeletal conditions, brain injury, spinal cord injury, cardiopulmonary disease, trauma, acute and chronic pain, amputation, prosthetics and orthotics, mobility, gait, and pediatrics as well as areas related to education and administration. Other important areas of interest include cancer rehabilitation, aging, and exercise. The Journal has recently published a series of articles on the topic of outcomes research. This well-established journal is the official scholarly publication of the Association of Academic Physiatrists (AAP).
