Abstract

Objective

Straight path gait under dual-task conditions recovers ∼2 months post-concussion. However, turning gait is more complex than straight path gait and may take longer to recover, especially under dual-task conditions. Therefore, the purpose of this study was to compare how individuals with and without a concussion history may differ in (1) turning gait spatiotemporal characteristics during single- and dual-task (serial 7 s) conditions, (2) the dual-task cost on the spatiotemporal characteristics and cognitive outcomes, and (3) the subjectively perceived task demands of single- and dual-task turning gait.

Methods

Twenty-three individuals with (age: 20.2 ± 1.9 years, BMI: 22.9 ± 2.7 kg/m², 60.9 % female, 44.7months [95 % CI=23.6, 65.7] months post-concussion) and 23 individuals without (age: 20.7 ± 1.7years, BMI: 22.4 ± 2.3 kg/m², 60.9 % female) a concussion history participated. Participants completed 3 trials of single-task serial subtraction, single-task figure-of-8 gait, and dual-task figure-of-8 gait. After each walking condition, participants completed the NASA Task Load Index to measure task demands.

Results

There was no significant group by cognitive load interaction for turning gait metrics (p-range=0.371–0.889) or task demands (i.e., NASA Task Load Index) (p = 0.598). There was no difference between groups for dual-task cost cognitive or gait outcomes (p-range=0.227–0.937). All participants displayed slower gait velocity (p < 0.001, Hedge’s g=1.149), greater double leg support percent (p < 0.001, Hedge’s g= 0.649), and wider step width (p = 0.003, Hedge’s g=0.644) during dual-task versus single-task figure-of-8 gait. Individuals with a concussion history displayed shorter step length compared to individuals without a concussion history (p = 0.014, Hedge’s g=0.664). All participants reported significantly lower task demands during single-task versus dual-task gait conditions (p < 0.001, Hedge’s g=1.532).

Conclusion

Those with a concussion history demonstrated moderately shorter step length, but the lack of any other significant findings limits clinical applicability. Greater perceived dual-task demands can be used to ensure more self-perceived challenges are being utilized during rehabilitation.

脑震荡病史对转身步态性能的影响

目的双任务条件下直线行走步态在脑震荡后恢复~ 2个月。然而，转弯步态比直线步态更复杂，需要更长的时间来恢复，特别是在双任务条件下。因此，本研究的目的是比较有和没有脑震荡病史的个体在(1)单任务和双任务（序列7 s）条件下转身步态时空特征的差异，(2)双任务成本对转身步态时空特征和认知结果的影响，以及(3)单任务和双任务转身步态的主观感知任务需求。 MethodsTwenty-three患者(年龄:20.2±1.9年 ,体重指数:22.9 ±2.7  kg / m2, 60.9 %女,44.7个月(95 % CI = 23.6, 65.7)个月后震荡)和23个人没有(年龄:20.7 ± 1.7岁,体重指数:22.4 ±2.3  kg / m2, 60.9 %女)脑震荡了历史。参与者完成了单任务连续减法、单任务8字形步态和双任务8字形步态的3个试验。在每个行走条件之后，参与者完成NASA任务负荷指数来衡量任务需求。结果认知负荷交互作用在转弯步态指标（p范围=0.371 ~ 0.889）和任务需求指标（即NASA任务负荷指数）上无显著性差异（p = 0.598）。双任务成本、认知或步态结果组间无差异（p范围= 0.227-0.937）。与单任务8字形步态相比，所有参与者在双任务中表现出更慢的步态速度（p <； 0.001，赫奇的g=1.149），更大的双腿支撑百分比（p <； 0.001，赫奇的g= 0.649）和更宽的步宽（p = 0.003，赫奇的g=0.644）。与没有脑震荡史的人相比，有脑震荡史的人的步长更短（p = 0.014,Hedge’s g=0.664）。所有参与者报告在单任务与双任务步态条件下的任务需求显著降低（p <； 0.001,Hedge 's g=1.532）。结论：有脑震荡史的患者步长较短，但缺乏其他重要发现限制了临床适用性。更大的感知双重任务需求可以用来确保在康复期间利用更多的自我感知挑战。
