The effects of electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation on ankle dorsiflexion during walking are unclear. This study investigated whether combined electrical stimulation training affects gait performance in patients with stroke. Thirty-six patients were randomly assigned to a control (n = 13), electromyography-triggered neuromuscular electrical stimulation training (single electrical stimulation group, n = 12), or a combined electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation training (combined electrical stimulation group, n = 11) group. Both experimental groups undertook 60-minute interventions for two weeks. All patients' gait performances were evaluated according to walking speed and trunk acceleration during 10-meter walking tests undertaken pre-intervention and at two weeks post-intervention. A wireless triaxial accelerometer measured trunk acceleration, and the root mean square values of the vertical, mediolateral, and anterioposterior planes were calculated from randomly selected 10-step sequences. Compared with baseline, the 10-meter walking tests improved significantly after two weeks in the single and combined electrical stimulation groups. In the combined electrical stimulation group, the 10-meter walking tests scores and root mean square of the mediolateral plane improved significantly compared with those in the control group. Electromyography-triggered neuromuscular electrical stimulation and tilt sensor functional electrical stimulation training may improve body perturbation stability and walking quality.
肌电图触发的神经肌肉电刺激和倾斜传感器功能性电刺激对步行过程中踝关节背屈的影响尚不清楚。本研究调查了联合电刺激训练是否会影响中风患者的步态表现。36名患者被随机分配到对照组（n = 13）、肌电图触发的神经肌肉电刺激训练组（单电刺激组，n = 12）或肌电图触发的神经肌肉电刺激与倾斜传感器功能性电刺激联合训练组（联合电刺激组，n = 11）。两个实验组均进行为期两周、每次60分钟的干预。在干预前和干预后两周进行的10米步行测试中，根据步行速度和躯干加速度对所有患者的步态表现进行评估。使用无线三轴加速度计测量躯干加速度，并从随机选择的10步序列中计算垂直、内外侧和前后平面的均方根值。与基线相比，单电刺激组和联合电刺激组在两周后的10米步行测试中有显著改善。联合电刺激组的10米步行测试分数和内外侧平面的均方根与对照组相比有显著改善。肌电图触发的神经肌肉电刺激和倾斜传感器功能性电刺激训练可能会提高身体扰动稳定性和步行质量。
