The aim of our study was to determinate the effects of foot orthoses on reducing pain and increasing function of athletes with patellofemoral pain syndrome who demonstrated excessive foot pronation. Materials and Methods: 418 female athletes between 15 &ndash; 35 years old in running, soccer, volleyball, fencing and mountain climbing were examinated. Among these athletes 25 subjects with patellofemoral pain syndrome had excessive foot pronation. The severity of pain was measured by VAS (visual analog scale) and their function were measured by KOOS (knee injury and osteoarthritis outcome score). Full length firm foot orthoses were given to athletes which at least 8 hours during the day was used. After 2 weeks: pain by VAS and function by KOOS were evaluated. After 6 weeks these variables were measured again. Results: The results of analysis of variance in repeated measures indicated a statistically significant improvement in pain by VAS after 2 weeks (p value=0.001) and after 6 weeks (p value=0.001). Improvement of function on KOOS were statistically significant at 5 subscales : reduction of symptoms after 2 weeks was not prominent but after 6 weeks was significant (p value=0.001) and reduction of pain after 2 weeks (p value=0.001), reduction of pain after 6 weeks (p value=0.001) and improvement of ADL after 2 weeks (p value=0.004) and after 6 weeks (p value = 0.001) and improvement of sport activities after 2 weeks (p value=0.012) and after 6 weeks (p value=0.001) and improvement in QOL after 6 weeks (p value=0.001). Conclusion: Our results confirmed a significant improvement in reducing pain and increasing function of female athletes with patellofemoral pain syndrome and excessive foot pronation after foot orthoses.</p> Key words: Knee pain, Foot pronation, Function, Foot orthoses, Female athletes 49 60 http://journal.zums.ac.ir/browse.php?a_code=A-10-4-479&slc_lang=fa&sid=1 Parisa Nejati پریسا نجاتی parisanejati@yahoo.com 5200319475328460060550 5200319475328460060550 Yes Dept. of Sports Medicine, Iran University of Medical Science, Tehran, Iran Bizhan Forugh بیژن فروغ 5200319475328460060551 5200319475328460060551 No Dept. of Physical Medicine and Rehabilitation, Firuzgar Hospital, Iran University of Medical Science, Tehran, Iran Jalil Kuhpayezade جلیل کوهپایه زاده 5200319475328460060552 5200319475328460060552 No Medical Education and Development Center, Iran University of Medical Science, Tehran, Iran Reza Moeineddin رضا معین الدین 5200319475328460060553 5200319475328460060553 No Shahid Beheshti University of Medical Science, Tehran, Iran Mina Nejati مینا نجاتی 5200319475328460060554 5200319475328460060554 No Ghazvin University of Medical Science, Iran
