Treadmills are important rehabilitation tools used with or without handrails. The handrails could be used to attain balance, prevent falls, and improve the walking biomechanics of stroke survivors, but it is yet unclear how the treadmill handrails impact their stability margins. Here, we investigated how 3 treadmill handrail-use conditions (no-hold, self-selected support, and light touch) impact stroke survivors' margins of stability (MoS). The anteroposterior MoS significantly increased for both legs with self-selected support while the mediolateral MoS of the unaffected leg decreased significantly when the participants walked with self-selected support in comparison to no-hold in both cases. We concluded that the contextual use of the handrail should guide its prescription for fall prevention or balance training in rehabilitation programs.
跑步机是一种重要的康复工具，可配备或不配备扶手。扶手可用于保持平衡、防止跌倒并改善中风幸存者的步行生物力学，但目前尚不清楚跑步机扶手如何影响他们的稳定裕度。在这里，我们研究了 3 种跑步机扶手使用条件（无扶手、自我选择支撑和轻轻触摸）如何影响中风幸存者的稳定性裕度（MoS）。与无扶手相比，自我选择支撑时，两条腿的前后向 MoS 均显著增加，而在自我选择支撑时，未受影响的腿的横向 MoS 显著降低。我们得出结论，扶手的使用情境应指导其在康复计划中预防跌倒或平衡训练中的使用。
