The purpose of this systematic review was to determine the viability of the dual-task paradigm in the evaluation of a sports-related concussion.
Systematic review and meta-analysis.
Eight electronic databases were searched from their inception until the 11(th) of April 2011. Studies were grouped according to their reported gait performance variables and their time(s) of assessment(s). Raw mean differences (MD) and 95% confidence intervals (CI) were calculated based on raw means and standard deviations for gait performance measures in both single- and dual-task conditions. Dual-task deficits were pooled using a random effects model and heterogeneity (I(2)) between studies was assessed.
Ten studies representing a total sample of 168 concussed and 167 matched (age and gender) non-concussed participants met the inclusion criteria. Meta-analysis demonstrated that dual-task performance deficits were detected (p<0.05) in the concussed group for gait velocity (GV) (MD=-0.133; 95% CI -0.197, -0.069) and range of motion of the centre of mass in the coronal plane (ML-ROM) (MD=0.007; 95% CI 0.002, 0.011), but not in the non-concussed group; GV (MD=-0.048; 95% CI -0.101, 0.006), ML-ROM (MD=0.002; 95% CI -0.001, 0.005).
The results of this study indicate that GV and ML-ROM are sensitive measures of dual-task related changes in concussed patients and should be considered as part of a comprehensive assessment for a sports-related concussion.
本系统评价的目的是确定双重任务范式在评估与运动相关的脑震荡中的可行性。
系统评价和荟萃分析。
从建库开始至 2011 年 4 月 11 日，对 8 个电子数据库进行了搜索。根据报告的步态表现变量及其评估时间，将研究进行分组。基于单任务和双任务条件下步态表现测量的原始平均值和标准差，计算原始差值（MD）和 95%置信区间（CI）。使用随机效应模型汇总双任务缺陷，并评估研究之间的异质性（I(2)）。
共有 10 项研究符合纳入标准，代表了总共 168 名脑震荡患者和 167 名匹配（年龄和性别）非脑震荡患者的样本。荟萃分析表明，在脑震荡组中，双任务表现缺陷在步态速度（GV）（MD=-0.133；95%CI-0.197，-0.069）和质心在冠状面的运动范围（ML-ROM）（MD=0.007；95%CI0.002，0.011）中被检测到（p<0.05），但在非脑震荡组中未被检测到；GV（MD=-0.048；95%CI-0.101，0.006），ML-ROM（MD=0.002；95%CI-0.001，0.005）。
本研究结果表明，GV 和 ML-ROM 是脑震荡患者双任务相关变化的敏感测量指标，应作为运动相关脑震荡综合评估的一部分考虑。
