女性跑步者患膝股关节疼痛时，常常会出现髋关节力学异常。我们试图评估一种简单的步态再训练技术，使用全身镜，对患有膝股关节疼痛和髋关节力学异常的女性跑步者进行评估。还评估了将新的运动技能转移到单腿蹲下和台阶下降等未经训练的任务中。10名患有膝股关节疼痛的女性跑步者在跑步机跑步过程中完成了8次镜像和口头反馈，以了解她们的腿部对齐情况。在过去的4个疗程中，镜像反馈和语言反馈逐渐被移除。在再训练前后，评估了跑步步态、单腿蹲下和台阶下降过程中的髋关节力学。受试者在再培训后1个月和3个月时恢复到正常的跑步程序，并重复分析。数据分析采用重复测量方差分析。受试者在跑步时髋关节内收、对侧骨盆下垂和髋关节外展力矩的峰值降低(P<；0.05，效应大小=0.69-2.91)。技能迁移到单腿蹲下和台阶下降(P<；0.05，效应量=0.91~1.35)。在再培训后1个月和3个月，大多数机械师在没有持续反馈的情况下保持不变。受试者报告了疼痛和功能的改善(P<；0.05，效果大小=3.81-7.61)，并在再培训后持续了3个月。镜面步态再训练能有效改善肢体力学、疼痛和功能指标。技能转移到未经训练的下蹲和台阶下降任务，表明运动学习达到了更高的水平。需要长期的随访来确定这种治疗的长期疗效。
Abnormal hip mechanics are often implicated in female runners with patellofemoral pain. We sought to evaluate a simple gait retraining technique, using a full-length mirror, in female runners with patellofemoral pain and abnormal hip mechanics. Transfer of the new motor skill to the untrained tasks of single leg squat and step descent was also evaluated. Ten female runners with patellofemoral pain completed 8 sessions of mirror and verbal feedback on their lower extremity alignment during treadmill running. During the last 4 sessions, mirror and verbal feedback were progressively removed. Hip mechanics were assessed during running gait, a single leg squat and a step descent, both pre- and post-retraining. Subjects returned to their normal running routines and analyses were repeated at 1-month and 3-month post-retraining. Data were analyzed via repeated measures analysis of variance. Subjects reduced peaks of hip adduction, contralateral pelvic drop, and hip abduction moment during running (P<0.05, effect size=0.69–2.91). Skill transfer to single leg squatting and step descent was noted (P<0.05, effect size=0.91–1.35). At 1 and 3 months post retraining, most mechanics were maintained in the absence of continued feedback. Subjects reported improvements in pain and function (P<0.05, effect size=3.81–7.61) and maintained through 3 months post retraining. Mirror gait retraining was effective in improving mechanics and measures of pain and function. Skill transfer to the untrained tasks of squatting and step descent indicated that a higher level of motor learning had occurred. Extended follow-up is needed to determine the long term efficacy of this treatment.
