Lateral wedged insoles, have shown positive effect on parameters like knee adduction moment and pain. As a result, the factors that have been shown to reduce the parameters associated with knee osteoarthritis are anticipated to be effective in improving balance. The aim of this study was to investigate the immediate and four-week effects of lateral wedged insoles on static balance in patients with mild and moderate osteoarthritis of knee medial compartment.&nbsp;<br> <strong>Methods:</strong> 18 patients (mean age=53&plusmn;6.07) and body mass index (26/1&plusmn;2.1 kg/m2) with painful mild and moderate knee osteoarthritis according to the Kellgren-Lawrence grading were recruited. Static standing balance was assessed while standing for 60 seconds on a force plate in three different footwear and two vision conditions: barefoot, wearing shoes without lateral wedged insoles and wearing shoes with lateral wedged insole in open and closed eye conditions. Pain intensity and static standing balance in the mediolateral direction (through the displacement and velocity of center of pressure) were investigated immediately and 4 weeks later.&nbsp;<br> <strong>Results: </strong>Lateral wedged insoles had no immediate effect on the center of pressure mediolateral displacement (<em>P</em>=0.70) and velocity (<em>P</em>=0.08). Using the lateral wedged insoles for 4 weeks resulted in significant improvement of pain (<em>P</em> <0.001) in mediolateral center of pressure displacement (<em>P</em> <0.001) and velocity (<em>P</em> <0.001).&nbsp;<br> <strong>Conclusion: </strong>No significant immediate effect was seen on the average displacement and velocity of the center of pressure in the mediolateral direction while wearing lateral wedged insoles. Measured parameters improved after 4 weeks. Effect of lateral wedged insoles as a non-invasive treatment can be considered for improving the postural balance in those with knee osteoarthritis.&nbsp;</span><br> &nbsp;</div> Foot Orthoses, Knee Osteoarthritis, Lateral Wedge, Static Balance 58 67 http://fdj.iums.ac.ir/browse.php?a_code=A-10-27-3&slc_lang=fa&sid=1 Mahsa Zangi مهسا زنگی Mahsa.zangi@gmail.com 1003194753284600655 1003194753284600655 No Orthotics and Prosthetics Department, Faculty of Rehabilitation Sciences, Iran University of Medical گروه ارتوپدی و پروتز, دانشکدۀ علوم توانبخشی، دانشگاه علوم پزشکی ایران، تهران، ایران Maryam Jalali مریم جلالی marjalali@gmail.com 1003194753284600656 1003194753284600656 Yes Orthotics and Prosthetics Department, Faculty of Rehabilitation Sciences, Iran University of Medical گروه ارتوپدی و پروتز, دانشکدۀ علوم توانبخشی، دانشگاه علوم پزشکی ایران، تهران، ایران Elham Esfandiari الهام اسفندیاری Esfandiari.elham@yahoo.com 1003194753284600657 1003194753284600657 No Orthotics and Prosthetics Department, Faculty of Rehabilitation Sciences, Iran University of Medical گروه ارتوپدی و پروتز, دانشکدۀ علوم توانبخشی، دانشگاه علوم پزشکی ایران، تهران، ایران Hamid Reza Yazdi حمیدرضا یزدی Dr.yazdi88@yahoo.com 1003194753284600658 1003194753284600658 No Firoozgar Hospital, Faculty of Medicine, Iran University of Medical Sciences, Tehran, Iran بیمارستان فیروزگر، دانشکدۀ پزشکی، دانشگاه علوم پزشکی ایران، تهران، ایران
