背景/目的：本研究评估了作用于骨盆、髋部和膝部肌肉的功能性电刺激 (FES) 对 3 名患有不完全脊髓损伤 (SCI) 的步行青少年的肌肉力量、步行能量消耗、最大步行距离和速度、步长和步频以及步态期间关节运动学的影响。方法：经皮 FES 用于增强虚弱的肌肉并增强步行能力。训练结束后，参与者使用 FES 在家中按照自己的意愿行走 1 年。在基线（干预前）、训练期后立即开启和关闭 FES 以及在训练后 3、6 和 12 个月开启和关闭 FES 的情况下收集数据。结果：13 块受刺激的肌肉中有 12 块的自愿力量有所改善。打开 FES 和关闭 FES 可以降低能量消耗、增加最大步行距离和速度、增加步长以及改善步态期间的关节运动学。讨论：FES 能够选择性刺激关键薄弱肌肉以增强步行能力。数据表明，FES 具有直接效应和遗留效应。
Background/Objective: This study evaluated the effects of functional electrical stimulation (FES) applied to the muscles acting on the pelvis, hip, and knee on muscle strength, energy cost of walking, maximum walking distance and speed, step length and cadence, and joint kinematics during gait in 3 ambulatory adolescents with incomplete spinal cord injury (SCI).Methods: Percutaneous FES was used to strengthen weakened muscles and to augment walking. After training, participants walked as desired at home with FES for 1 year. Data were collected at baseline (preintervention), and with FES on and FES off immediately following the training period and with FES on and FES off at 3, 6, and 12 months posttraining.Results: Voluntary strength improved in 12 out of 13 stimulated muscles. Decreased energy cost, increased maximum walking distance and speed, increased step length, and improved joint kinematics during gait were demonstrated with FES on and FES off.Discussion: FES was able to achieve selective stimulation of key weakened muscles for augmented walking. The data suggest that FES had both direct and carryover effects.
