摘要

背景:步态障碍在等待全膝关节置换术的膝关节骨性关节炎患者中很常见,影响他们的活动能力和生活质量。本研究旨在评估和比较等待全膝关节置换术的个体与健康、无关节炎对照者的生物力学步态特征,重点关注使用基于传感器的测量方法较少探索的变量。方法:对60名参与者进行了一项横断面观察性研究:21名等待全膝关节置换术的患者和39名年龄在64-85岁的无关节炎的对照组。参与者完成了标准化的14米步行,并使用BTS G-Walk惯性传感器测量了17个生物力学步态参数。关键变量,如步幅、节奏、对称指数和骨盆角,分析组间差异。结果:与对照组相比,全膝关节置换术前组步态周期和步幅持续时间明显延长(p < 0.001),步频明显降低(p < 0.001),步态周期对称指数明显降低(p < 0.001)。骨盆倾斜(p = 0.014)、旋转(p = 0.002)和倾斜(p < 0.001)的角度对称指数也较低。此外,全膝关节置换术前两腿推进指数较低(p < 0.001),右腿行走质量指数较低(p = 0.005)。在全膝关节置换术前组中,详细步骤的数量显著增加(左,p < 0.001,右:p < 0.001)。其他步态参数均无显著差异。结论:这项研究揭示了在等待全膝关节置换术的个体中显著的步态障碍。虽然缺乏康复的直接证据,但未来的研究应该探索是否有针对性的方法,如加强锻炼或步态再训练,可以在手术前改善步态和功能结果。

Wearable Sensor Assessment of Gait Characteristics in Individuals Awaiting Total Knee Arthroplasty: A Cross-Sectional, Observational Study.

Background: Gait impairments are common in individuals with knee osteoarthritis awaiting total knee arthroplasty, affecting their mobility and quality of life. This study aimed to assess and compare biomechanical gait features between individuals awaiting total knee arthroplasty and healthy, non-arthritic controls, focusing on less-explored variables using sensor-based measurements. Methods: A cross-sectional observational study was conducted with 60 participants: 21 individuals awaiting total knee arthroplasty and 39 nonarthritic controls aged 64-85 years. Participants completed a standardized 14 m walk, and 17 biomechanical gait parameters were measured using the BTS G-Walk inertial sensor. Key variables, such as stride duration, cadence, symmetry indices, and pelvic angles, were analyzed for group differences. Results: The pre-total knee arthroplasty group exhibited significantly longer gait cycles and stride durations (p < 0.001), reduced cadence (p < 0.001), and lower gait cycle symmetry index (p < 0.001) than the control group. The pelvic angle symmetry indices for tilt (p = 0.014), rotation (p = 0.002), and obliquity (p < 0.001) were also lower. Additionally, the pre-total knee arthroplasty group had lower propulsion indices for both legs (p < 0.001) and a lower walking quality index on the right leg (p = 0.005). The number of elaborated steps was significantly greater in the pre-total knee arthroplasty group (left, p < 0.001, right: p < 0.001). No significant differences were observed in any other gait parameters. Conclusions: This study revealed significant gait impairment in individuals awaiting total knee arthroplasty. Although direct evidence for prehabilitation is lacking, future research should explore whether targeted approaches, such as strengthening exercises or gait retraining, can improve gait and functional outcomes before surgery.
