en پژوهشي Original Research Articles <p style="text-align: justify;"><strong>Objectives:</strong> Ankle Foot Orthoses (AFOs) are widely utilized to improve walking ability in&nbsp;hemiplegic patients. The present study aimed to evaluate the effect of Rocker bar Ankle Foot&nbsp;Orthosis (RAFO) on functional mobility in post-stroke hemiplegic patients.<br> <strong>Methods:</strong> Fifteen hemiplegic patients (men and women) who were at least 6-months poststroke&nbsp;and able to walk without an assistive device for at least 10 meters voluntarily participated&nbsp;in this study. The patients were examined for three conditions: shoes only, with SAFO and with&nbsp;RAFO. Their functional mobility was evaluated through 10-meter walk test and Timed Up and<br> Go (TUG) test. In addition, paired t-test was used to analyze the obtained data.<br> <strong>Results: </strong>When the patients used RAFO, their gait speed significantly increased (P<0.05).&nbsp;Moreover, the time of performing TUG test experienced a significant decrease using RAFO&nbsp;compared with utilizing shoe only (P<0.05).<br> <strong>Discussion:</strong> RAFO led to a significant improvement in functional mobility in hemiplegic&nbsp;patients post stroke. This may be due to the positive effect of rocker modification on improving&nbsp;push off and transferring weight during the stance phase of gait.</p> Rocker bar ankle foot orthosis, Functional mobility, Hemiplegic patients 31 34 http://irj.uswr.ac.ir/browse.php?a_code=A-10-201-5&slc_lang=en&sid=1 Farzad Farmani No Department of Orthotics & Prosthetics, School of Rehabilitation Sciences, Hamedan University of Medical Sciences, Hamadan, Iran.
