OBJECTIVE
Adapt the 6 minutes walking test (6MWT) to artificial gait in complete spinal cord injured (SCI) patients aided by neuromuscular electrical stimulation.
METHOD
Nine male individuals with paraplegia (AIS A) participated in this study. Lesion levels varied between T4 and T12 and time post injured from 4 to 13 years. Patients performed 6MWT 1 and 6MWT 2. They used neuromuscular electrical stimulation, and were aided by a walker. The differences between two 6MWT were assessed by using a paired t test. Multiple r-squared was also calculated.
RESULTS
The 6MWT 1 and 6MWT 2 were not statistically different for heart rate, distance, mean speed and blood pressure. Multiple r-squared (r2 = 0.96) explained 96% of the variation in the distance walked.
CONCLUSION
The use of 6MWT in artificial gait towards assessing exercise walking capacity is reproducible and easy to apply. It can be used to assess SCI artificial gait clinical performance.
目的
使6分钟步行试验（6MWT）适用于在神经肌肉电刺激辅助下的完全性脊髓损伤（SCI）患者的人工步态。
方法
9名男性截瘫患者（美国脊髓损伤协会损伤分级A 级）参与了本研究。损伤平面在T4至T12之间，受伤时间为4至13年。患者进行了6MWT 1和6MWT 2。他们使用神经肌肉电刺激，并借助助行器。通过配对t检验评估两次6MWT之间的差异。还计算了多重决定系数。
结果
6MWT 1和6MWT 2在心率、距离、平均速度和血压方面无统计学差异。多重决定系数（r2 = 0.96）解释了步行距离变化的96%。
结论
在人工步态中使用6MWT来评估运动步行能力具有可重复性且易于应用。它可用于评估SCI人工步态的临床性能。
