foot orthoses have been described as a possible intervention for individuals with patellofemoral joint pain. No study has attempted to quantify the perceived comfort and support of foot orthoses when used as an intervention for patellofemoral joint pain.
a randomized case-control trial with crossover between contoured and flat orthoses was conducted on ten individuals with patellofemoral pain and ten healthy participants. All of the participants completed a comfort-support assessment and had in-shoe plantar pressure data collected before and after 3 weeks of wear. A 1-week washout period was used to minimize any continued treatment effect between orthotics testing. The patellofemoral pain group also completed a numeric rating scale to assess pain reduction after using each orthosis.
all of the participants perceived that greater support was provided by the contoured orthoses in the heel and arch regions. Even with a 30% difference in material hardness between the two orthoses, all of the participants rated cushioning as equivalent. Six individuals in the patellofemoral pain group reported a clinically significant reduction in knee pain as a result of wearing foot orthoses.
a key factor in the selection of contoured foot orthoses versus flat inserts is the amount of support that an individual perceives in the arch and heel regions. In addition, clinicians using foot orthoses as an intervention for patellofemoral pain should expect an individualistic, nonsystematic response.
足部矫形器已被描述为髌股关节疼痛患者的一种可能干预措施。尚无研究试图量化足部矫形器作为髌股关节疼痛干预措施时的舒适度和支撑感。
对10名髌股关节疼痛患者和10名健康参与者进行了一项随机病例对照试验，试验采用了轮廓型和扁平型矫形器交叉使用的方式。所有参与者均完成了舒适度 - 支撑度评估，并在佩戴3周前后收集了鞋内足底压力数据。采用1周的洗脱期以尽量减少矫形器测试之间的任何持续治疗效果。髌股关节疼痛组还完成了数字评分量表，以评估使用每种矫形器后的疼痛减轻情况。
所有参与者都认为轮廓型矫形器在足跟和足弓区域提供了更大的支撑。即使两种矫形器的材料硬度相差30%，所有参与者对缓冲的评分仍相当。髌股关节疼痛组中有6人报告称，佩戴足部矫形器后膝关节疼痛有临床显著减轻。
选择轮廓型足部矫形器而非扁平鞋垫的一个关键因素是个体在足弓和足跟区域感受到的支撑量。此外，将足部矫形器作为髌股关节疼痛干预措施的临床医生应预期会得到个体化的、非系统性的反应。
