恢复平衡控制是中风后康复的主要焦点。该研究开发了一种步态扰动，基于跑步机的平衡评估方案，并证明它可用于量化中风后个体反应性平衡反应的改善。该协议包括一系列的15个90秒的跑步机行走试验，在每个试验的中间三分之一期间施加一个扰动。在随机选择的步态周期中，在未受影响的腿的中间站立位，通过跑步机带的快速加速-减速来扰乱步态。初始扰动幅度基于参与者的最大步行速度，并且在每次试验中基于恢复的成功或失败而增加或减少，如从仪表化安全带确定的。该方案在24名中风幸存者接受10周治疗前后使用。结果包括最大可恢复扰动（MRP）、自行选择的步态速度、通过算法进展的水平以及跌倒与恢复的对比福尔斯。参与者能够采取恢复步骤来应对扰动。12名参与者在治疗干预前后完成了完整的评估方案。干预后，他们的福尔斯更少，恢复更多（p < 0.001），通过更多的算法水平（p = 0.043），有更高的MRP（p = 0.005），并有更高的步态速度。该方案被认为是可行的中风幸存者中度步态缺陷。数据支持的结论是，该协议可用于临床研究，以量化步行过程中的平衡改善。
Restoration of balance control is a primary focus of rehabilitation after a stroke. The study developed a gait perturbation, treadmill-based, balance assessment protocol and demonstrated that it can be used to quantify improvements in reactive balance responses among individuals post-stroke. The protocol consists of a sequence of fifteen 90-second treadmill walking trials, with a single perturbation applied during the middle third of each trial. Gait was perturbed by rapid acceleration-deceleration of the treadmill belt at midstance of the unaffected leg during a randomly selected gait cycle. The initial perturbation magnitude was based on the participant’s maximum walking speed and increased or decreased in each trial, based on success or failure of recovery, as determined from an instrumented harness. The protocol was used before and after a 10-week period of therapy in twenty-four stroke survivors. Outcomes included maximum recoverable perturbation (MRP), self-selected gait speed, levels progressed through the algorithm, and falls versus recoveries. Participants were able to take recovery steps in response to the perturbation. Twelve participants completed the full assessment protocol before and after the therapeutic intervention. After the intervention, they had fewer falls and more recoveries (p < 0.001), progressed through more algorithm levels (p = 0.043), had a higher MRP (p = 0.005), and had higher gait speeds. The protocol was found to be feasible in stroke survivors with moderate gait deficits. The data supports the conclusion that this protocol can be used in clinical research to quantify improvements in balance during walking.
