To determine the effects of functional electrical stimulation (FES) on the main impairments affecting gait in children with unilateral spastic cerebral palsy.
A 20-week, multiple single-subject A-B-A design included a 6-week pre-FES phase, an 8-week FES phase, and a 6-week post-FES phase. Twelve children, aged 5 to 16 years, wore an FES device (the Walk Aide) daily for 8 weeks. Weekly measures included ankle range of motion, selective motor control, dorsiflexion and plantar flexion strength, gastrocnemius spasticity, single-limb balance, Observational Gait Scale (OGS) score, and self-reported toe drag and falls in the community.
Compared with the pre-FES phase, the FES phase showed significant improvements in ankle range of motion, selective motor control and strength, and reductions in spasticity, toe drag, and falls, but no change in OGS score. These improvements were maintained during the post-FES phase.
Intermittent, short-term use of FES is potentially effective for reducing impairments affecting gait in children with unilateral spastic cerebral palsy.
确定功能性电刺激（FES）对影响单侧痉挛性脑瘫患儿步态的主要损伤的作用。
采用为期20周的多单受试者A - B - A设计，包括6周的FES前阶段、8周的FES阶段和6周的FES后阶段。12名年龄在5至16岁的儿童每天佩戴FES装置（步行辅助器），持续8周。每周测量的指标包括踝关节活动范围、选择性运动控制、背屈和跖屈力量、腓肠肌痉挛、单腿平衡、观察性步态量表（OGS）评分，以及自我报告的在社区中的拖趾情况和跌倒次数。
与FES前阶段相比，FES阶段在踝关节活动范围、选择性运动控制和力量方面有显著改善，痉挛、拖趾和跌倒次数减少，但OGS评分无变化。这些改善在FES后阶段得以维持。
间歇性、短期使用FES可能对减少影响单侧痉挛性脑瘫患儿步态的损伤有效。
