目的：观察两种平衡训练策略对脑卒中患者下肢运动功能恢复的影响。方法：选取脑卒中患者 63 例， 采用随机数字表法将其随机分为对照组和观察组，其中对照组 31 例，观察组 32 例。对照组在常规康复治疗的基础上， 接受姿势矫正镜下的平衡训练；观察组患者在常规康复治疗的基础上，接受平衡训练仪下的平衡训练。两组患者的 平衡训练时间均为 4 周。于治疗前和治疗 4 周后采用部分静态平衡仪测试参数（轨迹总长度、轨迹面积图和速度图）、 Berg 平衡量表（Berg Balance Scale，BBS）、10 m 最大步行速度（Maximum Walking Speed，MWS）和计时起立 - 行 走测试（Timed Up and Go Test，TUGT），分别评估患者的静态平衡能力、步行速度和移动能力。结果：治疗 4 周后， 行组内比较，两组患者的部分静态平衡仪测试参数、BBS、MWS 和 TUGT 结果较治疗前均显著改善，差异有统计学 意义（P<0.05）；组间比较，两组患者的部分静态平衡仪测试参数、BBS 和 MWS 相比，差异有统计学意义（P<0.05）； 而两组的 TUGT 结果相比，差别无统计学意义（P>0.05）。结论：与姿势矫正镜下进行平衡训练相比，采用平衡训 练仪能够有效改善脑卒中患者的静态平衡下压力中心（Center of Pressure，COP）的轨迹总长度、轨迹面积图和速度图， 能提高患者的平衡能力和步行速度，加速患者下肢运动功能的恢复。

Objective: To observe the effect of two different balance training strategies on recovery of lower limb motor function in stroke patients. Methods: 63 stroke patients with hemiplegia in our hospital were selected and randomly divided into control group and study group, including 31 patients in the control group and 32 patients in the observation group. The control group was given balance training under postural mirror and routine rehabilitation treatment, and the observation group were given balance training under the balance training instrument and routine rehabilitation treatment. All patients were trained for 4 weeks. Using part of the static balance test parameters (including total path length, path area and velocity diagram), Berg Balance Scale (BBS), 10-meter Maximum Walking Speed (MWS) and Timed Up & Go Test (TUGT) to evaluate static balance ability, balance function, walking speed and mobility of patients respectively before and 4 weeks after treatment. Result: After 4 weeks of treatment, the results of static balance test, BBS, MWS and TUGT in the two groups were significantly improved compared with those before treatment (P<0.05). Static balance test, BBS and MWS results between the two groups showed statistically significant differences (P<0.05), while TUGT results showed no statistically significant differences between the two groups (P> 0.05). Conclusion: Compared with the balance training under postural mirror, the balance training with balance instrument could effectively improve the total path length, path area and velocity diagram on the speed of center of pressure (COP) of stroke patients, as well as improve the balance ability and walking speed of patients and accelerate their recovery of lower limb motor function.
