Passive dynamic ankle-foot orthoses have potential to facilitate return to running after a lower limb trauma. However, transitioning patients to new movement patterns that enhance passive dynamic ankle-foot orthoses benefits can pose a challenge. The purpose of this case study was to report biomechanical and functional outcomes for a patient utilizing a passive dynamic ankle-foot orthoses following completion of a session-based, midfoot strike run training program.
A patient using a passive dynamic ankle-foot orthoses to run due to surgically reconstructed tibia\fibula fracture underwent eight treadmill running sessions over 2 weeks while viewing continuous visual feedback on measured foot strike.
After treatment, foot strike was changed from rearfoot to midfoot on the affected limb along with an 18% increase in mechanical work ratio of the ankle-foot-brace complex. Similar improvements were retained at one and five months following treatment.
This report provides preliminary evidence that biofeedback-based foot strike training can enhance ankle-foot mechanical performance of patients using a passive dynamic ankle-foot orthoses to run.
For patients using a passive dynamic ankle-foot orthoses to run following lower limb trauma, supplementing standard rehabilitation programs with biofeedback-based footstrike training may improve biomechanical performance and running capability.
被动动态踝足矫形器具有促进下肢创伤后恢复跑步的潜力。然而，让患者过渡到能增强被动动态踝足矫形器益处的新运动模式可能具有挑战性。本病例研究的目的是报告一名患者在完成基于阶段的中足着地跑步训练计划后使用被动动态踝足矫形器的生物力学和功能结果。
一名因胫腓骨骨折手术重建而使用被动动态踝足矫形器跑步的患者，在2周内进行了8次跑步机跑步训练，同时观看关于实测着地方式的连续视觉反馈。
治疗后，患侧肢体的着地方式从后足变为中足，踝足矫形器复合体的机械功比增加了18%。治疗后1个月和5个月时保持了类似的改善。
本报告提供了初步证据，表明基于生物反馈的着地训练可增强使用被动动态踝足矫形器跑步的患者的踝足机械性能。
对于下肢创伤后使用被动动态踝足矫形器跑步的患者，在标准康复计划中补充基于生物反馈的着地训练可能会改善生物力学性能和跑步能力。
