【摘要】 目的 探讨惯性步态设备在评估脑卒中患者 6 分钟步行试验（6MWT）中评估步态参数的可行性及其与 Berg 平衡量表之间的潜在联系。方法 回顾性分析 2021-06—2021-08 于北京康复医院进行康复的脑卒中患者 30 例，患者佩戴惯性步态设备并以自适应步速进行 6MWT，评价指标包括步行距离、步态的时空及运动学参数等。受试前采用 Berg 平衡量表对患者进行平衡能力的评价。结果 所有脑卒中患者均佩戴惯性步态设备完成了 6MWT，患者在 6MWT 中完成的第一圈（T1）与最后一圈（T2）之间步态差异无统计学意义（P=0.055~0.968），患侧下肢支撑相时长百分比（66.58±3.69）%与单支撑相时长百分比（29.92±5.47）%均小于非患侧［（70.14±5.07）%、（33.21±4.17）%］，差异有统计学意义（P=0.003、0.011）。6MWT 步行距离、步速及步长与 Berg 平衡量表之间呈高度相关（r=0.610~0.695，P=0.001）。结论 在6MWT中利用惯性步态设备能够提供关于脑卒中患者步行功能的步态数据，可能可作为评估脑卒中患者的步行功能的一种有效补充。

【Abstract】 Objective To explore the feasibility of inertial gait devices in assessing gait parameters in the 6-minute walk test （6MWT） in stroke patients and their potential association with the Berg balance scale.Methods Thirty stroke patients were included in Beijing Rehabilitation Hospital from June 2021 to August 2021. Patients wore an inertial gait device and performed 6MWT at an adaptive gait speed，and evaluation indexes included walking distance，temporal and kinematic parameters of gait. Each patient’s balance was evaluated using the Berg Balance Scale before being tested. Results All stroke patients completed the 6MWT wearing inertial gait devices，and there was no statistically significant difference in gait between the first（T1）and last（T2）laps completed by patients in the 6MWT（P value 0.055-0.968），and the percentage of time spent in the support phase of the affected lower limb（66.58±3.69）% and the percentage of time spent in the single support phase （29.92 ± 5.47）% were smaller than those on the non-affected side（（70.14 ± 5.07）%，（33.21 ± 4.17）%），with statistically significant differences（P value 0.003，0.011）. There was a high correlation between MWT walking distance，stride speed and stride length and Berg balance scale（r=0.610- 0.695，P value 0.001）. Conclusion The use of inertial gait devices in the 6MWT can provide gait data on walking function in stroke patients and may be a useful supplement to assess walking function in stroke patients.
