研究设计：单队列研究。目的：探讨跑步机步态训练期间提供的实时生物反馈对纠正无症状女性步行时膝关节过度伸展的效果。背景：膝关节过度伸展与膝关节后囊、前十字韧带和胫股关节前室的应力增加有关。以前旨在纠正膝关节过度伸展的方法取得的成功有限。 方法：10 名年龄在 18 至 39 岁之间、在行走过程中无症状的膝关节过度伸展的女性，在跑步机训练期间接受了 6 次实时运动学数据反馈 (Visual 3D)。在训练前、训练后和最后一次训练后 1 个月进行步态评估。结果：参与者在训练后和训练后 1 个月以 1.3 m/s 的速度在地上行走时对膝关节过度伸展的控制得到改善。结论：本研究表明，使用实时生物反馈进行步态再训练可能会影响膝关节矢状面运动学。 J Orthop Sports Phys Ther 201141(12):948-952，Epub 2011 年 10 月 25 日。doi:10.2519/jospt.2011.3660
STUDY DESIGN: Single cohort study.OBJECTIVES: To investigate the efficacy of real-time biofeedback provided during treadmill gait training to correct knee hyperextension in asymptomatic females while walking.BACKGROUND: Knee hyperextension is associated with increased stress to the posterior capsule of the knee joint, anterior cruciate ligament, and the anterior compartment of the tibiofemoral joint. Previous methods aimed at correcting knee hyperextension have shown limited success.METHODS: Ten women, ages 18 to 39 years, with asymptomatic knee hyperextension during ambulation, were provided with 6 sessions of realtime feedback of kinematic data (Visual 3D) during treadmill training. Gait evaluations were performed pretraining, posttraining, and 1 month after the last training session.RESULTS: Participants showed improved control of knee hyperextension during overground walking at 1.3 m/s at posttraining and at 1 month posttraining.CONCLUSION: The present study demonstrated that knee sagittal plane kinematics may be influenced by gait retraining using realtime biofeedback.
