中枢神经系统的损伤往往会导致对行走功能产生负面影响的损伤。先前的证据表明，振动可能会改善步行功能。这项研究的目的是确定重复使用全身振动(WBV)是否与脊髓损伤(SCI)患者步行功能的改善有关。研究对象为17名慢性运动不全脊髓损伤患者(≥1岁)。受试者在参加为期12个疗程(每周3天-为期4周)的WBV干预之前和之后进行测试。我们通过3D运动捕捉来评估行走功能的变化，以行走速度作为主要的结果衡量标准。我们还评估了WBV干预对二次步态特征的影响，包括步调、步长和髋角-膝角的腿内协调性。步行速度平均提高0.062±0.011米/S，差异有统计学意义(P<；0.001)。WBV干预也与节奏的显著增加有关，较强和较弱的腿都表现出步长增加和肢体内协调一致性的改善。更强壮的腿的步速和步长的变化与步行速度的提高密切相关。通过WBV干预观察到的步行速度的改善与文献中与运动训练相关的报告相当。即使在非临床人群中，这种大小的变化也被确认为具有临床意义。这些发现表明，WBV可能有助于改善步行功能，其影响可能会在干预后持续一段时间。
Injury to the central nervous system often results in impairments that negatively affect walking function. Prior evidence suggests that vibration may improve walking function. The purpose of this study was to determine whether repeated use of whole-body vibration (WBV) is associated with improvements in walking function in individuals with spinal cord injury (SCI). Subjects were 17 individuals with chronic (≥ 1 year), motor-incomplete SCI. Subjects were tested before and after participation in a 12-session (3 days/week- for 4 weeks) intervention of WBV. We assessed change in walking function via 3D motion capture, with walking speed as the primary outcome measure. We also assessed the influence of the WBV intervention on secondary gait characteristics, including cadence, step length, and hip angle-to-knee angle intralimb coordination. Walking speed increased by a mean of 0.062 ± 0.011 m/s, a change that was statistically significant (p<0.001). The WBV intervention was also associated with statistically significant increases in cadence, and both the stronger and weaker legs exhibited increased step length and improved consistency of intralimb coordination. Changes in cadence and step length of the stronger leg were strongly correlated with improvements in walking speed. The improvement in walking speed observed with the WBV intervention was comparable to that reported in the literature in association with locomotor training. This magnitude of change has been identified as being clinically meaningful, even in non-clinical populations. These findings suggest WBV may be useful to improve walking function with effects that may persist for some time following the intervention.
