Abstract

Individuals with an incomplete spinal cord injury (iSCI) have increased risk of falls during walking and standing. Our previous longitudinal pilot study demonstrated that a therapeutic system (FES+VFT system) using functional electrical stimulation (FES) and visual feedback training (VFT) improved the standing balance of individuals with iSCI. This study investigated the orthotic and acute therapeutic effects of FES in the FES+VFT system. Fifteen individuals with iSCI will be recruited for this study. To date, four participants have completed the study. The four participants completed three different sessions. In the first session, participants were evaluated for their balance, postural control and familiarized with the FES+VFT system. In the second and third sessions, the participant completed training sessions with the FES+VFT system with or without FES. Centre of pressure (COP) data were collected via force platforms. Before and after the training, the motor evoked potentials (MEP) of the soleus and tibialis anterior muscles were recorded. There was a greater increase in the total dynamic range of the COP with FES+VFT than VFT (Anterior posterior: increase of 17.5 ± 14.27mm, medial lateral: increase of 17.9 ± 19.45mm). Both the soleus and tibialis anterior muscles showed greater increases in MEP after FES+VFT than VFT (Soleus: 70.4 ± 31.1% vs 5.45 ± 29.1%; Tibialis Anterior: 115.3 ± 234.8% vs 11.0 ± 42.9%). These findings suggest that FES improves the performance of VFT (positive orthotic effect) and increases the corticospinal connection (positive acute therapeutic effect) in individuals with iSCI.

不完全脊髓损伤(iSCI)患者在行走和站立时跌倒的风险增加。我们之前的纵向试验研究表明,使用功能性电刺激(FES)和视觉反馈训练(VFT)的治疗系统(FES+VFT 系统)可改善不完全脊髓损伤患者的站立平衡能力。 本研究调查了 FES+VFT 系统中 FES 的矫形和急性治疗效果。 本研究将招募 15 名 iSCI 患者。迄今为止,已有四名参与者完成了研究。 这四名参与者完成了三个不同的疗程。在第一个疗程中,参与者接受了平衡和姿势控制评估,并熟悉了 FES+VFT 系统。在第二和第三个疗程中,参与者使用或不使用 FES 完成了 FES+VFT 系统的训练。压力中心(COP)数据通过测力平台收集。在训练前后,记录了比目鱼肌和胫前肌的运动诱发电位(MEP)。 与 VFT 相比,FES+VFT 增加的 COP 总动态范围更大(前后侧:增加 17.5 ± 14.27 毫米,内外侧:增加 17.9 ± 19.45 毫米)。比目鱼肌和胫骨前肌在 FES+VFT 后的 MEP 增幅均大于 VFT(比目鱼肌:70.4 ± 31.1% vs 5.45 ± 29.1%;胫骨前肌:115.3 ± 234.8% vs 11.0 ± 42.9%)。 这些研究结果表明,FES 可改善 iSCI 患者 VFT 的表现(积极的矫形效果),并增加皮质脊髓连接(积极的急性治疗效果)。
