Passive and hybrid passive ankle foot orthoses (AFOs) are often prescribed in these patients. Although, the effects of these AFO designs on spatiotemporal parameters during gait in passive ankle foot orthoses were investigated in many studies, the effect of different types of hybrid passives of these AFOs in these parameters seem unclear.<br> The aim of current study was to compare the efficiency of newly designed pneumatic damper ankle-foot orthoses (PD-AFO) with posterior leaf spring ankle-foot orthoses (PLS AFO) in drop foot.<br> <strong>Methods:</strong> For this reason, ten drop foot patients were recruited for this study, walked at self-selected comfortable speed and three dimensional motion analysis systems were used to obtain spatiotemporal gait parameters.<br> <strong>Results:</strong> Pneumatic damper AFOs were showed significantly increase in the speed,&nbsp; cadence, step width, percent of single support time, percent of double support time, step and stride time on the paretic side and step length (p<0.005).<br> <strong>Conclusion:</strong> This newly designed pneumatic damper AFO significantly improved spatiotemporal parameters than PLS AFO.</div> Drop foot, Ankle foot orthosis, spatiotemporal parameters, Gait 171 176 http://fdj.iums.ac.ir/browse.php?a_code=A-10-75-2&slc_lang=en&sid=1 Hassan Saeedi حسن سعیدی Hassan_saeedi2@yahoo.co.uk. 10031947532846001701 10031947532846001701 No Rehabilitation Research Center, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran مرکز تحقیقات گروه ارتوز و پروتز، دانشکده توانبخشی دانشگاه علوم پزشکی ایران، تهران، ایران.
