[Purpose] Treadmill-based interventions are widely utilized in rehabilitation due to their advantages of providing controlled environments and enabling individualized training. However, the differences between overground and treadmill walking during the subacute rehabilitation phase remain incompletely understood. This study aimed to compare gait parameters between treadmill walking at varying speeds and overground walking in a subacute rehabilitation setting. [Participants and Methods] A total of 42 inpatients with cerebrovascular and orthopedic conditions were recruited from a convalescent rehabilitation ward. Gait parameters were measured using the Gait Real-time Analysis Interactive Lab (GRAIL) system during comfortable overground walking and treadmill walking at various speeds, including self-selected comfortable speeds and speeds matched to overground walking. Walking speed, stride length, cadence, and step width were calculated without markers and compared across conditions. [Results] The comfortable treadmill walking speed was significantly lower than the overground walking speed (mean [standard deviation]: 0.85 [0.23] m/s vs. 1.20 [0.20] m/s). Stride length was significantly shorter during treadmill walking at comfortable speeds compared to overground walking (0.86 [0.22] m vs. 1.21 [0.18] m), whereas step width was significantly wider (0.17 [0.04] m vs. 0.13 [0.03] m). [Conclusion] Maintaining cadence at reduced treadmill speeds promotes comfortable endurance training in subacute rehabilitation patients.
[目的] 基于跑步机的干预措施因其能提供可控环境并实现个性化训练的优势，在康复治疗中被广泛应用。然而，亚急性康复阶段在地面行走和跑步机行走之间的差异仍未被完全理解。本研究旨在比较亚急性康复环境下不同速度的跑步机行走与地面行走之间的步态参数。[参与者与方法] 从康复疗养病房招募了42名患有脑血管疾病和骨科疾病的住院患者。在舒适的地面行走以及不同速度的跑步机行走过程中，使用步态实时分析交互实验室（GRAIL）系统测量步态参数，包括自我选择的舒适速度以及与地面行走相匹配的速度。在不使用标记物的情况下计算步行速度、步长、步频和步宽，并对不同条件下的结果进行比较。[结果] 舒适的跑步机行走速度显著低于地面行走速度（平均值[标准差]：0.85[0.23]米/秒对1.20[0.20]米/秒）。与地面行走相比，在舒适速度下跑步机行走时步长显著缩短（0.86[0.22]米对1.21[0.18]米），而步宽显著变宽（0.17[0.04]米对0.13[0.03]米）。[结论] 在降低的跑步机速度下保持步频可促进亚急性康复患者进行舒适的耐力训练。
