There is limited information on the relationship between plantar foot pressure and patellofemoral pain syndrome (PFPS). In addition, there is not enough research on the effects of an infrapatellar strap on PFPS.
The aim of this study was to evaluate the immediate effects of an infrapatellar strap on dynamic pedabarography in patients with unilateral PFPS.
Clinical case control study design. 18 females subjects with unilateral PFPS were included in the study. Gait parameters were tested using pedabarography during barefoot walking with and without an infrapatellar strap.
There were no statistically significant differences in gait trials comparing infrapatellar strap to no strap (P>0.05). In addition, a significant difference (P=0.043) in the % forefoot surface on the involved side demonstrated that body weight is transferred to medial aspect of the foot.
Although our results show a difference between the forefoot surface % of the affected and unaffected sides of subjects with PFPS there was no indication that an infrapatellar strap had any immediate effect on this parameter.
It is not clear whether PFPS is a cause or effect of abnormal gait. Further research is warranted to investigate the long-term effects of wearing an infrapatellar strap and associated altered foot biomechanics due to PFPS.
关于足底压力与髌股疼痛综合征（PFPS）之间关系的信息有限。此外，关于髌下束带对PFPS影响的研究也不够充分。
本研究旨在评估髌下束带对单侧PFPS患者动态足底压力测量的即时影响。
采用临床病例对照研究设计。18名单侧PFPS女性受试者纳入研究。在佩戴和不佩戴髌下束带的情况下，通过足底压力测量仪测试赤脚行走时的步态参数。
比较佩戴髌下束带和不佩戴束带的步态试验，差异无统计学意义（P>0.05）。此外，患侧前足表面积百分比存在显著差异（P=0.043），表明体重转移至足部内侧。
虽然我们的结果显示PFPS患者患侧与未患侧前足表面积百分比存在差异，但没有迹象表明髌下束带对该参数有任何即时影响。
尚不清楚PFPS是异常步态的原因还是结果。有必要进一步研究佩戴髌下束带的长期影响以及PFPS导致的足部生物力学改变。
