目的.评估脊髓损伤（SCI）后骨密度（BMD）的变化，并评估功能性电刺激骑自行车运动（FESCE）干预是否可以逆转BMD丢失。纳入了15名SCI男性患者。还对15名身体健全的男性进行了BMD比较。脊髓损伤组进行6个月的FESCE，然后在随后的6个月内停止。在FESCE前、FESCE后6个月及随后6个月末分别进行BMD检查。在FESCE之前，SCI受试者除腰椎外的所有部位的BMD均低于健全受试者。FESCE治疗6个月后，股骨远端（DF）和胫骨近端（PT）的BMD显著增加，跟骨（足跟）的BMD呈增加趋势。然而，在随后的6个月没有FESCE后，DF，PT和足跟的BMD显著下降。股骨颈（FN）的BMD在整个程序中进行性下降。我们的研究显示FESCE后部位特异性BMD变化。在6个月的FESCE后，DF和PT的BMD损失部分逆转，但一旦运动停止，这种影响就会消失。
Purpose. To assess the change in bone mineral density (BMD) after spinal cord injury (SCI) and to evaluate whether BMD loss can be reversed with the intervention of functional electric stimulation cycling exercises (FESCE).Methods. Fifteen males with SCI were included. Fifteen able-bodied males were also tested to compare BMD. In the SCI group, the FESCE was performed for six months, and then was discontinued in the subsequent six months. BMD was performed before the FESCE, immediately after six months of the FESCE, and at the end of the subsequent six months.Results. Before the FESCE, the BMD of the SCI subjects in every site, except the lumbar spine, was lower than that of the able-bodied subjects. After six months of FESCE, BMD of the distal femur (DF) and proximal tibia (PT) increased significantly, and BMD of the calcaneus (heel) showed a trend of increase. However, the BMD in the DF, PT, and heel decreased significantly after the subsequent six months without FESCE. The BMD of the femoral neck (FN) decreased progressively throughout the programme.Conclusions. Our study showed site-specific BMD changes after FESCE. The BMD loss in the DF and PT was partially reversed after six months of FESCE, but the effect faded once the exercise was discontinued.
