目的：确定 SCI 后两年内实施功能性电刺激 (FES) 划船计划对骨矿物质密度 (BMD) 的影响。设计：前瞻性。设置：医疗机构。参与者：方便样本；四名近期（<2 年）患有创伤性运动性完全性 SCI (C7-T12 AIS A-B) 的成年人。干预：90 次 FES 划船锻炼计划；参与者在参与期间每周大约参加 3 次 30 分钟的 FES 培训课程。 结果测量：在入组时 (T0) 以及 30 (T1)、60 (T2) 和 90 (T3) 课程后，使用外周定量计算机断层扫描 (pQCT) 测量股骨远端和胫骨的 BMD。使用前一个时间点的平均每周负荷周期数、峰值足反作用力和骨矿物质含量，计算每个划船者在每个时间点的骨刺激。使用回归分析来确定计算的骨刺激与时间点之间股骨小梁 BMD 变化之间的关系。 结果：所有参与者的股骨和胫骨骨小梁 BMD 在 T0-1 期间均下降，但在 T1-2 期间损失率减慢或逆转，大多数参与者在 T2-3 期间几乎没有骨损失。计算出的骨刺激与股骨小梁 BMD 的变化显着相关（P = 0.016；R2= 0.458）。结论：持续参与 FES 划船计划提供了足够的力量和加载周期，至少暂时地减少或逆转了 SCI 后两年内某些个体股骨远端和胫骨的预期骨质流失。试验注册：NCT02008149。
Objective: To determine the effect of a functional electrical stimulation (FES) rowing program on bone mineral density (BMD) when implemented within two years after SCI.Design: Prospective.Setting: Health Care Facility.Participants: Convenience sample; four adults with recent (<2 years) traumatic, motor complete SCI (C7-T12 AIS A-B).Intervention: A 90-session FES rowing exercise program; participants attended 30-minute FES training sessions approximately three times each week for the duration of their participation.Outcome Measures: BMD in the distal femur and tibia were measured using peripheral Quantitative Computed Tomography (pQCT) at enrollment (T0) and after 30 (T1), 60 (T2), and 90 (T3) sessions. Bone stimulus was calculated for each rower at each time point using the average number of weekly loading cycles, peak foot reaction force, and bone mineral content from the previous time point. A regression analysis was used to determine the relationship between calculated bone stimulus and change in femoral trabecular BMD between time points.Results: Trabecular BMD in the femur and tibia decreased for all participants in T0-1, but the rate of loss slowed or reversed between T1-2, with little-to-no bone loss for most participants during T2-3. The calculated bone stimulus was significantly correlated with change in femoral trabecular BMD (P = 0.016; R2= 0.458).Conclusion: Consistent participation in an FES rowing program provides sufficient forces and loading cycles to reduce or reverse expected bone loss at the distal femur and tibia, at least temporarily, in some individuals within two years after SCI.Trial Registration: NCT02008149.
