摘要： 目的 探讨执行计算-平衡双重任务时，注意力分配原则对平衡能力和计算能力的影响。 方法 2016年10月至2017年12月，选取健康青年人20例，于坐位下进行睁眼+计算、闭眼+计算测试，于静态平衡仪上分别进行单腿站立+睁眼、单腿站立+闭眼、单腿站立+睁眼+计算、单腿站立+闭眼+计算测试。记录身体重心的左右最大摆幅、前后最大摆幅，外周面积，轨迹长，以及连续逆序减７计算的正确率。 结果 睁眼时身体重心左右、前后最大摆幅，外周面积，轨迹长显著小于闭眼时(t > 8.775, P < 0.001)；双重任务闭眼时身体重心左右、前后最大摆幅，外周面积小于单项任务(t > 2.276, P < 0.05)；双重任务睁眼时身体重心的左右、前后最大摆幅，外周面积，轨迹长与单项任务相比无显著性差异(t < 1.379, P > 0.05)。睁眼坐位组、闭眼坐位组、睁眼平衡测试组、闭眼平衡测试组计算正确率无显著性差异(P > 0.05)。 结论 低难度的认知双重任务不通过注意力分配原则来影响平衡稳定性和计算能力，计算任务反而改善闭眼时的单腿静态平衡稳定性，但对睁眼时的平衡稳定性无影响。

Abstract: Objective To explore the impact of attentional distribution principle on balance and arithmetic ability when performing calculation-balance dual task. Methods From October, 2016 to December, 2017, 20 healthy young subjects were selected, and asked to perform eyes opened + calculation and eyes closed + calculation tests under sitting position, and perform single leg standing + eyes opened, single leg standing + eyes closed, single leg standing + eyes opened+ calculation and single leg standing + eyes closed + calculation tests in the static balance instrument. The maximum displacement in mediolateral direction and anteroposterior direction of center of gravity, sway area and sway path length were recorded, as well as the accuracy of counting backwards in steps of seven. Results The maximum displacement in mediolateral direction and anteroposterior direction, sway area, sway path length were significantly less when eyes opened than eyes closed (t > 8.775, P < 0.001). The maximum displacement in mediolateral direction and anteroposterior direction, and sway area were less when eyes closed during the dual task than single task (t > 2.276, P < 0.05). There was no statistical difference in the maximum displacement in mediolateral direction and anteroposterior direction, and sway area and sway path length when eyes opened during the dual task compared with single task (t < 1.379, P > 0.05). There was no significant difference in the calculation accuracy among the eyes opened + sitting group, the eyes closed + sitting group, the eyes opened + balance test group and the eyes closed + balance test groups (P > 0.05). Conclusion The low-difficult cognitive dual task does not affect the balance stability and arithmetic ability through the attentional distribution principle, on the contrary, the arithmetic task improves the static balance ability of single leg standing when eyes closed, however, it has no effect on the static balance ability of single leg standing when eyes opened.
