目的：探索早期认知障碍患者双重任务下步态参数与认知功能之间的关系。
方法：本研究共纳入轻度认知障碍者（MCI）20例，主观认知下降者（SCD） 34例，认知功能正常者（NC）24例，均采用三维运动捕捉系统及建模仿真分析软件进行单任务及双重任务下步态参数（步长、步速、步频、步态周期）的采集与分析。
结果：双重任务下MCI组步频（步/min）（102.173±11.941）小于SCD组步频（110.500±10.435）（P<0.01）；MCI组步态周期（s）（1.209±0.133）较NC组步态周期（1.122±0.117）和SCD组步态周期长（1.116±0.102）（P<0.01）。NC组在双重任务下步长（m）及步速（m/s）下降（P<0.01）；SCD组在双重任务下步长、步速及步频均下降（P<0.05）；MCI组在双重任务下步速、步频及步态周期均下降（P<0.01）。相关性分析显示步速与记忆和语言功能存在正性相关(P=0.005，r=0.312；P=0.014，r=0.277；P=0.005，r=0.317)，步频与记忆功能存在正性相关(P=0.010，r=0.289；P=0.012，r=0.283)，步态周期与记忆功能存在负性相关(P=0.001，r=﹣0.354)，与执行功能存在正性相关(P=0.022，r=0.258)。
结论：双重任务下步态参数可作为早期评估认知功能的辅助指标。 |

| Abstract
Objective： To explore the relationship between gait parameters and cognitive function in patients with early cognitive impairment under dual task condition.
Method： Twenty patients with mild cognitive impairment， thirty four patients with subjective cognitive decline， and 24 normal cognition elderly were included in this study. Three-dimensional motion capture system and modeling analysis software were used to collect and analyse gait parameters (step length， step speed， cadence and gait cycle).
Result： The cadence (steps/min) of the MCI group (102.173±11.941) was lower than that of the SCD group (110.500±10.435) (P<0.01)； the stride time(s) of the MCI group (1.209±0.133) was longer than that of the NC group (1.122±0.117) and SCD group (1.116±0.102) (P<0.01). The step length(m) and gait speed(m/s) of the NC group decreased under the dual task condition (P<0.01)； the step length, gait speed and cadence of the SCD group decreased under the dual task condition(P<0.05) and the gait speed，cadence and stride time decreased under the dual task condition in MCI group (P<0.01). The correlation analysis showed that there was a positive correlation between gait speed and memory as well as language function(P=0.005，r=0.312；P=0.014，r=0.277；P=0.005，r=0.317)， a positive correlation between cadence and memory function (P=0.010，r=0.289；P=0.012，r=0.283)， a negative correlation between gait cycle and memory and a positive correlation between executive function(P=0.001，r=﹣0.354；P=0.022，r=0.258).
Conclusion： Gait parameters under dual task condition in patients with early cognitive impairment can be used as an early auxiliary index of cognitive function. |
