本研究旨在评估应用于腓神经和大腿肌肉的功能性电刺激（FES）对轻偏瘫受试者步态表现的影响。参与者为45名轻偏瘫（自诊断以来5.37 ± 5.43年）受试者（年龄57.8 ± 14.8岁），表现出足下垂和膝关节控制受损。根据影响步态的功能障碍，对股四头肌或腘绳肌进行大腿刺激。在有/无刺激和仅用腓神经刺激的两分钟步行试验期间评估步态。第二次评估是在每天使用六周后进行的。在初始和第二次评估时，将大腿肌肉刺激添加到腓骨刺激显著增强了步态速度测量。双通道刺激仅在初始评估时增强步态对称性，而单肢站立百分比仅在第二次评估时增强。例如，6周后，腓神经刺激和双通道的2分钟步态速度分别为0.66 ± 0.30 m/sec和0.70 ± 0.31 m/sec（P < 0.0001）。总之，双通道功能电刺激可以提高偏瘫患者的步态表现，优于单纯腓神经功能电刺激。
The study objective was to assess the effect of functional electrical stimulation (FES) applied to the peroneal nerve and thigh muscles on gait performance in subjects with hemiparesis. Participants were 45 subjects (age 57.8 ± 14.8 years) with hemiparesis (5.37 ± 5.43 years since diagnosis) demonstrating a foot-drop and impaired knee control. Thigh stimulation was applied either to the quadriceps or hamstrings muscles, depending on the dysfunction most affecting gait. Gait was assessed during a two-minute walk test with/without stimulation and with peroneal stimulation alone. A second assessment was conducted after six weeks of daily use. The addition of thigh muscles stimulation to peroneal stimulation significantly enhanced gait velocity measures at the initial and second evaluation. Gait symmetry was enhanced by the dual-channel stimulation only at the initial evaluation, and single-limb stance percentage only at the second assessment. For example, after six weeks, the two-minute gait speed with peroneal stimulation and with the dual channel was 0.66 ± 0.30 m/sec and 0.70 ± 0.31 m/sec, respectively (P < 0.0001). In conclusion, dual-channel FES may enhance gait performance in subjects with hemiparesis more than peroneal FES alone.
