Recumbent stationary cycling is a potential exercise modality for individuals with cerebral palsy (CP) that lack the postural control needed for upright exercises. Functional electrical stimulation (FES) of lower extremity muscles can help such individuals reach the cycling intensities that are required for aerobic benefits. The aim of this study was to examine the effect of cycling with and without FES assistance to that of a no-intervention control group on the cardiorespiratory fitness of children with CP. Thirty-nine participants were randomized to a FES group that underwent an 8-week FES-assisted cycling program, the volitional group (VOL), who cycled without FES, or a no-intervention control group (CON) (15 FES, 11 VOL, 13 CON). Cadence, peak VO, and net rise in heart rate were assessed at baseline, end of training, and washout (8-weeks after cessation of training). Latent growth curve modeling was used for analysis. The FES group showed significantly higher cycling cadences than the VOL and CON groups at POST and WO. There were no differences in improvements in the peak VO and peak net HR between groups. FES-assisted cycling may help children with CP attain higher cycling cadences and to retain these gains after training cessation. Higher training intensities may be necessary to obtain improvements in peak VO and heart rate.
卧姿固定自行车运动是一种对于脑瘫（CP）患者潜在的运动方式，因为他们缺乏进行直立运动所需的姿势控制能力。下肢肌肉功能性电刺激（FES）可以帮助这些患者达到进行有氧运动所需的自行车运动强度。本研究的目的是检验在有或没有 FES 辅助的自行车运动与不干预对照组之间对 CP 儿童心肺功能适应性的影响。39 名参与者被随机分配到 FES 组（接受 8 周 FES 辅助自行车运动计划）、自主组（VOL，不进行 FES 辅助的自行车运动）或不干预对照组（CON）（15 名 FES、11 名 VOL、13 名 CON）。在基线、训练结束和洗脱期（训练停止 8 周后）评估踏频、峰值 VO 和心率净升。使用潜在增长曲线模型进行分析。与 VOL 和 CON 组相比，FES 组在 POST 和 WO 时的自行车踏频明显更高。各组在峰值 VO 和峰值净 HR 的改善方面没有差异。FES 辅助自行车运动可能有助于 CP 儿童达到更高的自行车踏频，并在训练停止后保持这些收益。可能需要更高的训练强度才能提高峰值 VO 和心率。
