胫骨应力性骨折是最常见的跑步相关损伤之一，与下肢负荷增加有关（即，胫骨的峰值正加速度、垂直力冲击峰值以及平均和瞬时垂直力加载速率）。本研究旨在评估步态再训练计划的有效性，旨在减少跑步过程中的这种负荷，并评估这些减少的短期持续性。10名跑步者（6名女性和4名男性）的峰值正胫骨加速度大于8克，在初步筛选中测量，参加了再培训计划。在再训练过程中，受试者在跑步机上跑步，并从胫骨远端的加速度计接收实时视觉反馈。在训练前、训练后和1个月随访时举行的地上数据收集会议期间，从受试者中收集胫骨加速度和垂直地面反作用力数据。峰值正加速度的胫骨，垂直力的冲击峰值，平均和瞬时垂直力加载率都降低后立即步态再训练。胫骨加速度降低近50%。垂直力加载速率和垂直力冲击峰值的降低分别约为30%和20%。这些降低在1个月随访时保持不变。受试者能够在完成步态再训练计划后立即和1个月随访评价时以降低的胫骨加速度和垂直力载荷跑步。这可能会降低其应力性骨折的风险。
Tibial stress fractures, which are among the most common running related injuries, have been associated with increased lower extremity loading (i.e., peak positive acceleration of the tibia, vertical force impact peak, and average and instantaneous vertical force loading rates) during initial contact. This study was conducted to evaluate the efficacy of a gait retraining program designed to reduce this loading during running and to assess the short-term persistence of these reductions. Ten runners (six females and four males) with peak positive tibial acceleration greater than 8 g, measured in an initial screening, participated in the retraining program. During the retraining sessions, subjects ran on a treadmill and received real-time visual feedback from an accelerometer attached to their distal tibias. Tibial acceleration and vertical ground reaction force data were collected from subjects during overground data collection sessions held pre-training, post-training, and at a 1-month follow-up. Peak positive acceleration of the tibia, vertical force impact peak, and average and instantaneous vertical force loading rates were all reduced immediately following the gait retraining. The decrease in tibial acceleration was nearly 50%. The reductions in vertical force loading rates and vertical force impact peak were approximately 30% and 20%, respectively. These reductions were maintained at the 1-month follow-up. Subjects were able to run with reduced tibial acceleration and vertical force loading immediately following completion of the gait retraining program and at the 1-month follow-up evaluation. This may reduce their risk of stress fractures.
